UK Lintels are pleased to announce the launch of our new Special Lintel Configurator. The new Configurator tool is a unique system that allows for the swift manufacture of bespoke lintels to the client’s chosen wall construction and lengths.

The Configurator tool is a simple step process, allowing the client to select;

  1. Special lintel type (Square bay or Corner)
  2. Chosen lengths
  3. Wall construction
  4. Delivery (next-day available when ordering before 9am)

Reducing manufacturing and lead times

Special Lintels such as corner and bay lintels are made to order items that typically require the client to request a quote and wait for a price – this can take up to a week. Once agreed, the client must wait for the manufacturer to offer a technical drawing for approval, followed by a manufacture time that could take between six to eight weeks.

This whole process takes months, meaning a build could be put on hold.

UK Lintels reduces from weeks and months, to hours and days. Just order online with our Configurator tool and receive next-day delivery.

Every house has a number of openings for doors and windows. Most of these are in structural load-bearing walls. These walls are critical to the building structure as they carry the load of the floor above them and the roof.

To support this weight, you need a solid lintel to span the gap and transfer the weight onto the surrounding walls. Each lintel must be carefully positioned and installed according to specific U.K. building regulations. By following these, you know that your lintel is capable of supporting the load above it.

Concrete lintels are a common type of lintel due to their low cost and long-term resistance to fire and corrosion. They also offer superior thermal insulation and can prevent cold bridging problems that occur with steel lintels.

If you’re interested in learning about concrete lintels and the best way to install them, you’re in the right place. In this guide, we’ll explain what the advantages of concrete lintels are and how to ensure they’re professionally installed.

How Lintels Work in Your Home

Whenever you have an opening in a wall the weight of the structure above it needs to be supported. A concrete lintel beam distributes this load onto the surrounding masonry. Without a lintel, all of the building’s weight would rest on top of the window or door frame.

These wooden and aluminium frames are not designed to withstand heavy loads. In comparison, precast concrete lintels are specifically designed and built to resist large downward forces. They distribute this pressure onto the adjacent walls which are then supported by the building floor slab and foundations.

Concrete lintels are usually constructed with steel bars embedded in the concrete. These reinforce the concrete and provide the structural integrity to resist large compressive loads. The steel also gives the lintel a small amount of flexibility to bend without breaking.

Why You Might Need a Lintel

If you’re planning some DIY home renovations that involve new windows or doors, it’s vital to find out which walls are load-bearing. Breaking open non-load bearing walls is possible for a home builder enthusiast that has some building experience.

It is not advisable to attempt to make changes to a load-bearing wall without the help of a professional builder. Structural alterations can be extremely dangerous and need to be approved by an engineer before you can make any new window or door openings.

Stressline Performance for Concrete Lintels

UKLintels are major stockists and suppliers of Stressline concrete lintels which are designed with concrete strength 50N/mm2 and offer a minimum of ½ hour fire resistance.

Apart from 140×65 and 215×65 lintel sections all other STANDARD lintels are reversible, which means that they can be used either way around to suit the wall construction. Always check loadings against our load span tables.

Hi-Strength lintels are marked ‘TOP’ and the surface must be kept at uppermost all times.

Steps to Install Concrete Lintels

Concrete lintel installation is a fairly easy process if you are building your home from the ground up rather than renovating existing walls. In this guide, we’ll discuss how to install a lintel in a new wall. Let’s break down each step in more detail.

Calculate Load-Bearing Weight

When buying concrete lintels online, it’s important to check the load distribution tables associated with the lintel and to seek advice from a structural engineer as to what section of concrete lintel is required.
These will give you the uniformly distributed load (UDL) that the lintel can support in kiloNewtons per meter (kN/m). They will also provide you with the resistance movement (RM) for each lintel.

Tools Needed

As most lintels are installed above head height, it’s important to have some sturdy scaffolding that can support your concrete lintel weight. You will also need a selection of standard masonry tools.

These should include:

Bed on Mortar

On each side of the lintel, you need to have enough space to adequately support the lintel. This is known as the minimum end bearing and should be at least 150mm. For lintels shorter than 1m, you can reduce this to 100mm. With lintels longer than 3m, you should extend it to 200mm.

Lintels should always be supported by full bricks or padstones to provide a solid base. Never use a cut brick and mortar as the base of the lintel as this will not distribute the weight evenly.

Once you’ve mixed up a nice firm consistency mortar you can apply it to the support on either side. Aim to distribute the mortar evenly on both sides. You can then place the lintel in position and bed it down into the mortar to ensure a thorough connection.

When installing a long lintel over 1.2m, it’s advisable to prop the lintel up at the centre point. You should leave this support in place until the mortar has set.

Ensure Its Level

As soon as the lintel is in position, it’s vital you use a spirit level to make sure it’s completely flat. It’s very important to spread the load evenly onto both sides of the support. You can use a straight edge laid along the top of the lintel to get a more accurate reading on your level.

It’s also important to check the level across the width of the lintel. This will provide you with a flat surface to place the next row of bricks on. Failing to check this can result in the rest of your wall having an undesirable angle.

Most walls require two lintels side by side to match the width of the wall. By making sure that these are exactly level you can distribute the load evenly across both lintels. If one is slightly higher than the other, you risk putting excess stress on the higher lintel.

Make sure the masonry must not overhang the lintel by more than 25mm.

Wait for the Mortar to Cure

Before you put any load on your new lintel, it’s important to allow the mortar enough time to dry. Depending on the environmental conditions, you should wait at least 24 to 36 hours. This is extremely important to keep the lintel completely level.

Once the mortar has cured you can then continue to build your walls. In some situations, it may be necessary to install a damp-proof course above your lintel. When that is in position, you can start laying bricks on the lintel. All external wall lintels MUST be installed with a DPC.

Always position your bricks in a way that evenly distributes the weight across the lintel. Avoid applying too much weight to either side as this can cause structural problems within the lintel. Avoid shock loading of lintels during the installation of concrete floor units and any sideways loading while being fitted into position. Precast flooring units should be laid on a mortar bed across the whole wall width and should not be dragged over supports.

Inspect the lintel prior to installation

Before you install the lintel, the lintel should be explained to check for any defects or signs of damage. You should also check it is the correct section as per your engineers calculations.

Advantages of Concrete Lintels

Precast concrete lintels have a number of benefits when compared to steel lintels. The most significant of these is the price difference. Concrete lintels are a considerably more cost-effective option than any other type of lintel.

If you live near the coast, then you’re all too familiar with the corrosive effects of salt-laden air. The steel reinforcement in concrete lintels is encased in concrete and this means they are less susceptible to corrosion.

Another benefit of concrete lintels is that they are more resistant to high temperatures resulting from fires. When steel is heated, it loses its structural integrity and can fail. Concrete lintels will last longer in the event of a house fire and will help prevent further damage.

The United Kingdom experienced record wind speeds of 122 miles per hour when Storm Eunice hit in early 2022.

We are no strangers to extreme winds in this part of the world. It is more important than ever to ensure stability when constructing homes and buildings. Experts believe that climate change will bring about more severe weather events in the years to come.

When it comes to construction, a windpost is a popular solution to provide extra stability to a wall.
Hundreds of years ago, our forefathers used heavy and oversized blocks of stone in their construction. A benefit of this is that it gave buildings added stability. Modern technology has made it quicker and easier to build houses.

But it has given us thinner masonry walls. This means we need extra support to ensure our homes last long and withstand extreme weather events and other structural issues.

But, what is a windpost, and do you need one? This article will teach you everything you need to know about windposts and their uses in construction.

What Is the Purpose of a Windpost?

There is never a wrong time to add an extension to your home or start that home improvement project you have always dreamt of. Whether you are looking for more space or hoping to upgrade your home, a construction project can be a significant learning curve.

Suppose you are doing a whole new building project, a major renovation that requires building walls, or a whole new floor. In this case, you may find, to your surprise, that your builder or architect is suggesting you install construction windposts.

Imagine you want to remove a wall between your kitchen and living room to create an open-plan kitchen. This may seem straightforward. However, in some specific cases, it can require structural additions such as a windpost to stabilise the build or to split a large panel of masonry.

In construction, windposts serve an essential purpose in providing stability. A windpost is a vertical steel structure usually spanning vertically from foundation to first floor, between floors, or from floor to roof. Windposts are supplied as a complete kit to include the vertical stem, bottom connection, top connection and wall ties and sometimes come with a fixing pack.

There are two general types of windpost;

  1. WP2 – Installed in the inner leaf of a cavity wall

2. WP1 & WP3 – Installed within the cavity between your brickwork inner and outer leaf leaving the brickwork undisturbed. 

In the past, if you needed stability, you would have built columns or made your walls thicker. If you tried this today, it would make your construction project much more expensive.

In recent decades there have been innovations in the building industry to make your walls more robust and resistant to bad weather and other forces. Windposts are an excellent way to add structural stability to your wall or to reduce the overall size of a panel of masonry.

Windposts are made of stainless steel or mild steel and post galvanized. However, you can fix them to a variety of materials. They can attach to timber, steel, or brick structures.

A structural engineer or architect who analyses your building plans will be able to recommend the proper spacing and placement of your windposts for your project.

How Are Windposts Supported?

If you want to stabilise your walls with windposts, you cannot just place the steel structure between the layers of brick. They need to have anchor points to provide the stability you need.

Windposts are often installed between the inner and outer leaf of a wall. However, you can also place them inside a cavity wall without disturbing the blockwork.

The windpost will often be bolted down into the foundation and supported between different floors. To do this, you will attach the windpost using a specific tie or connection. The type of tie you need will depend on the frame and the design.

These wall ties play a crucial role in reducing the lateral load from the wall. They also allow the structure to move without cracking.

Wall ties will also be placed between the bricks at several points as the wall is constructed. An engineer will calculate the intervals at which you need to tie it. When you buy windposts for construction, you will use special screws and bolts to attach to a steel beam, concrete, or timber structure.

Different Types of Windposts

You will get various types of windposts to fit the particular job you are doing.

As you can see, there are more than enough options to suit any construction project.

When Do You Need Windposts?

If a structural engineer has said you need to install windposts, you might be wondering why they are even necessary.

As their name suggests, windposts provide valuable protection to a structure if it faces exposure to high winds, earthquakes, or hurricanes. But they also offer stability from pressures that the structure itself can create and reduce the overall panel of masonry.

If you have an extensive panel of bricks or a wall that is longer than a certain distance, you may need several windposts to stabilise the structure. Your engineer may also recommend windposts if your building has several floors.

A classic use of windposts is for bi-folding or concertina doors.

We all want as much light as possible to enter our homes. In modern design, it is popular to have a large door sliding open to give full access to a terrace or garden.

The downside is that when you have such a wide opening in the brickwork, you lose stability. Windposts will be necessary to add the support you need.

If you live in an area with a high risk of extreme winds or earthquakes, you will also need to add windposts to your construction. Even living by the seaside could increase your exposure to elements which weaken the stability of your building.

When Are Windposts Not Necessary?

If you are building a small, one-storey home, you may not require windposts. The same applies if you are only constructing a small extension.

In a tiny building, there are fewer instances of large panels of masonry that will impact the stability. Wind load is more of a concern in tall buildings that use heavy materials.

If you do not have large openings for big windows or sliding doors, you do not have to worry about installing windposts unless otherwise advised by your structural engineer.

How to Order and Design Windposts

So, you have found out that you need windposts. Unfortunately, you cannot just walk down to your local home improvement store and buy as many as you need.

Typically, windposts are bespoke items. You have to get an engineer or architect to assist you in specially designing the windposts you need for your construction project. A manufacturer can configure them to your specific needs but this process will involve issuing construction drawings for review and the manufacturer will provide a technical drawing for approval prior to manufacture. This process can be stressful for the client, and can take up to 4 weeks. Once approved, the manufacture time will be an additional 4 weeks making the whole process take months to receive your product.

Windpost design has advantages because you will know that you are getting a custom-fit product. However, this means a wait of several weeks to receive your product. It also doesn’t allow for errors during this technical phase where often the wrong stem length is provided making the delivered product useless and the process needs to be started again. The global supply chain crisis has made waiting times even longer and led to price increases in the construction industry.

Is There a Faster Way to Receive Windposts?

Some people find out they will need windposts when they have already begun building. The idea of losing time and money by waiting for months can be a massive headache.

Another option to get your windposts sooner is by ordering them to your specific requirements.

You can buy three component parts separately, which will be put together at your building site.

The three parts you can order online are:

You will want to do this in close coordination with a structural engineer. Technical specifications and drawings are available to guide you and your builder. You will receive a product leaflet with tips for the installation of your windpost.

The top connection will be a choice of fitting to attach to a timber, steel, or concrete beam. 

Next, you will decide on the length of the stem you will need.

The options are:

The top brackets are open brackets so the top connection bracket can slide up and down the windpost. Once the top bracket is fixed in to place, the remaining stem can either be left sailing in to the cavity, or cut off on site with a disc cutter and the cut end treated with cold zinc spray which can be purchased online.

For your base connection, you can choose between a top or a side fix to a concrete base.

Various extension plates are also available to fit your specific project. This is because cavity wall sizes change with various cavity sizes, inner and outer leaf widths. Typical walls can be anything from 250mm overall (100mm inner leaf, 50mm cavity, 100mm outer leaf) to 405mm. In addition, the position of the windpost within the cavity can sometimes be central or more towards one side (often closer to the inner leaf).

The standard baseplate on our top and bottom brackets therefore sometimes need to be extended to allow for these variations.The extension plates enable this via mechanically fixing additional plates to the existing bracket. Each extension plate consists of two plates and 4 bolts and extend the bracket by 100mm as shown below.

All windpost require tying into the inner and outer wall with the use of wall ties. We recommend that a wall tie pack is added to your configuration as we supply the stainless steel wall tie, tek-screw/ washer and an isolation pad to debond the stainless steel tie from the galvanized stem to prohibit cross contamination of materials.

Wall ties are installed to suit the brick coursing (usually at 225mm ctrs). Each tie pack consists of 30no stainless steel wall ties, 30no Isolation Pads, 30no Tek Screws. You can select the tie length required using the options online from 75mm to 200mm tie lengths.

The length of the tie should be sufficient to allow an embedment of at least 62.5mm meaning the minimum embedment of 50mm is always achieved after allowing for site tolerances. The tie length will depend on the overall cavity size, and the position of the windpost within the cavity. Should you require a tie pack with one side longer than the other as shown below, then you will need to add an additional tie pack to your order.

That’s it, next day delivery available.

Your windpost is built and can be added to basket (select the qty required) and delivered next day if required (various delivery options are available to select at basket/checkout).

Windpost Design Made Fast and Easy

A construction site can be an unpredictable place. You cannot always tell how long a project will take and what problems will crop up.

Finding out you need a windpost can add to your stress, especially if it will take months to arrive. This can stall your project and cost you money.

Our unique windpost configurator provides a quick and easy solution to this dilemma for galvanized WP3 Windpost (85x60x5 Section).

As the new year rolls in, we’re seeing continued increases in both demand and costs for raw materials leading to an unfortunate but inevitable increase in prices for lintels in 2022. We believe the other major steel lintel manufacturers will follow suit with Keystone/IG and Birtley Lintels expecting similar increases around the same time.

Here are the headlines –

As we have referenced before here at UK Lintels, the industry cannot absorb these costs as quotes from industry will outline:

“Our sector continues to experience a significant upturn in demand for building materials, however in addition we have also seen a dramatic increase in the costs to raw materials, plus other outside costs which unfortunately we are unable to absorb.”

Richard Smith, Stressline Sales & Marketing Manager

“The continued inflation on raw material, transport and packaging costs for GALVANISED STEEL LINTELS and ACCESSORIES is likely to remain at elevated levels for the foreseeable future, and we are unable to absorb these additional costs. I therefore wish to formally notify you of a price increase of 10% to our list prices, which shall be effective from 1st March 2022. As always, our efforts are directed at mitigating additional cost to you and we only pass on increases when absolutely necessary. Your business is extremely important to us.”

Mike Murphy, Catnic Sales & Marketing Director

After a volatile 2021 in the steel lintel market where we witnessed two price increases from Catnic (15.0% 1.04.21) (18.0% 1.07.21) we predicted a third increase would emerge in Q4 2021. We had hoped that prices would stabilise but the announced increase in Q1 2022 are showing no signs of price stability for this coming year. The impact of Covid-19 on the UK’s workforce is still extremely prominent and macro-economic factors such as gas prices are compounding the raw material costs and transportation issues on our sector. To combat this UKLintels have increased their stock holding in 2021 by 500% and invested in further vehicles. By having the stock on the ground means we are not relying on the manufacturers lead-times and can continue to offer steel lintels next working day, nationwide. Our own vehicles give us the flexibility as well as certainty for our distribution channels for our client orders.

Folding doors used to mean cheap MDF panels that constantly jumped the track. But today’s bi-fold doors provide an elegant and functional way to make your living space more flexible.

Because the door panels fold and stack as the doors are opened, you can turn a wall into a large opening. But since this means the wall goes away, proper support across the top of the opening is crucial to hold the doors in place when closed and keep the roof from falling in when open.

The horizontal beam or lintel running across the top of the door jam provides that structural support. While the lintel can have some give or flex for standard doors and windows, it needs to maintain its straight line for bi-fold doors to function properly. 

Let’s take a look at what makes a lintel for a bi-fold door different and how to choose the proper one.

Types of Lintels

Lintels are found above all the doors and windows of a house, with different types called for depending on the size of the opening and the amount of load. They hold up the upper floors and roof where there is no wall to do so.

Here’s a quick look at your choices:

Which Lintel for Bi-fold Doors?

Normal structural loads in a building come from the roof trusses, exterior masonry, and floor joists. Your choice of lintel has to take into account the amount of load. For bi-fold doors, you have an additional load as the lintel has to be able to support the additional weight of the doors when they are closed.

Most exterior openings use lintels of concrete, wood, or steel. Because even a small bend can keep your doors from sliding open or shut. This is known as permissible deflection for lintels and most bi-fold door manufacturers would request that a lintel is installed with a maximum deflection of less than 5mm. A Lintel should not exceed a maximum vertical deflection of 0.003 x the effective span (effective span = distance between centre of bearings) when subjected to the safe working load (SWL). heavy-duty steel is recommended for bi-fold doors, especially for large openings.

As a minimum we would recommend looking at our Extra Heavy Duty Range. In most circumstances we would recommend using our CXL Lintels (Extreme Load Lintel) (the links take you to a 50-65mm cavity lintel, please select the cavity size required from the dropdown box). CXL Extreme load lintels offer the minimum deflection in our lintel range. These are in stock up to 6.0m long in every cavity size (50,60,70,90,110,130,150mm).

Below is a table of loadings that these lintels can achieve. To achieve the loading figures shown, the lintel must be laterally restrained and have 200mm end bearing supports and inner to outer load ratios between 5:1 and 19:1. Please consult a structural engineer to check the product suitability and deflection for your project prior to ordering.

Structural Considerations

Bi-fold doors add dramatic flair to your space along with flexibility. Added to an exterior wall, these doors can extend a living room into the patio. Added to an internal wall, they allow separate rooms to turn into a single larger space when needed.

But adding a bi-fold door requires more considerations than a standard opening. The installation has to take into account the thickness of the walls and the size of the opening. Your choice of lintel must also consider the weight of the door, the type of masonry above the door, and how much masonry is on either side of the opening. Loading ratios should also be taken into consideration. Safe working loads (SWL) as defined by BS 5977:Part 2: 1983 for cavity wall lintels refer to uniform distributed loads applied in the inner to outer leaf ratios:

Your choice of a door should also be taken into consideration. Top-running doors put more load on the lintel than bottom-running doors, which get more support from the floor.

For this reason, there can be a lot of math involved in choosing the right type and size for your new bi-fold door, which is where a structural engineer comes in. The larger the size or the more the new door will vary from the old, the more helpful it can be to have a professional work with you to ensure you have adequate structural support.

Size, load, and movement have the most impact on choice and installation. Size is simply figured by measuring the size of your opening and adding at least 150mm to each end for support (200mm for CXL profiles). Going beyond that delivers extra cost more than it does extra support.

Lintel Installation

Whether you plan to replace an existing door or add in a new feature, installation starts by calculating how much support your doors will need. A steel lintel is a safe bet to handle the weight of your door and the load of the above structure.

Bi-fold doors can be placed on an interior or exterior wall and even added to a load-bearing wall. Opening up a load-bearing wall to add a door can weaken it as there is less to support the weight of the upstairs floors and the roof. A rolled steel lintel can provide the extra support that ensures the wall won’t collapse under the weight.

Proper installation should involve bedding the lintel in the mortar and placed perfectly level. Both are important to ensure the load is evenly distributed. Mortar should be cured adequately to ensure the load is transferred through the lintel to the walls on either side of the door.

Installing a Bi-fold Door?

Bi-fold doors open your home to more light and add flexibility to your interior layout. Installing them requires adding a lintel across the top to provide structure to the opening and support the weight of the doors. For bi-fold doors, steel lintels make your best option as they have the strength for the job.
