You will get various types of windposts to fit the particular job you are doing. There are four general catagories of windpost. Within each catagory there will also be various sizes available. UKLintels offer their own system of each of these for your consideration and engineers approval prior to ordering online.

WP2 – Angle (L shape) system built within the inner leaf of a cavity wall
WHAT IS A WP2 WINDPOST?

WP1 & WP3 – Channel (C Shape) system built within the cavity void leaving the brickwork undisturbed. 
WHAT IS A WP3 WINDPOST?

DU – Double WP3 (welded or bolted back to back) installed within the cavity between your brickwork inner and outer leaf leaving the brickwork undisturbed.
WHAT IS A DU WINDPOST?

Visit our Windpost Superstore now to build and order online any of the above Windposts.

SHS – A box section (Square Hollow Section) installed within the inner leaf or within the cavity void.
WHAT IS AN SHS WINDPOST?

WP2 Windposts – An angle system that sits within the inner leaf brickwork and is tied to the inner leaf with 100mm long wall ties. The angle is also tied to the outer leaf brickwork with longer wall ties. The angle is fixed at the base and top with brackets and cleats.

You can CONFIGURE ONLINE a WP2 windpost (150x90x10) section. Below is an explanation of how to use our online configurator with various tips for each stage.

The top connection will be a choice of fitting to attach to Timber, Steel or Concrete beam. You may also download our PDF Installation guide.

Step 1 – Select your top connection bracket. Once the top bracket is fixed in to place, the remaining stem can either be built in to your inner skin, or cut off on site with a disc cutter and the cut end treated with cold zinc spray which can be purchased online. The various options are shown on screen and click NEXT once you have made your selection.

Step 2 – You will decide on the length of the stem you will need. 2m to 3m stems come as one piece. Whereas, 4.0m+ options are two or three stems with a collar bracket connections. The collar bracket and bolts are supplied as part of the kit when you select these lengths and the stems are pre-dilled by UKLintels before delivery.

Step 3 – select your base connection. WP2 windposts are built within the inner wall and therefore the WP2 system has only one base connection offering. Select the below base connections for your windpost and click next. The below sketch shows the stem installed to a 100mm wide inner skin. The baseplate will sit within the cavity as shown.

Step 4 – Various extension plates are also available to suit your specific project. This is because you may wish to have a longer plate for your top connection cleat than our standard 150mm long T1 & T2. Should you need to lengthen the overall dimension of the plate length to T1, T2 then select a plate extension pack (2 plates per pack & 4no set bolts) will lengthen the plate with a mechanical bolt fixing by 100mm per pack. You can have as many packs as you like!

Step 5 – 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 27no ties at 100mm and 13no of your own choice, 40no Isolation Pads, 40no Tek Screws. You can select the Tie B length required using the options online from 75mm to 200mm tie lengths.

Unlike the image below our stems are not pre-slotted for your ties. This gives far more flexibility on site with your brick coursing. The overall sketch below gives a generic example of how a WP2 may be installed within a cavity wall with a base fixing and top cleat fixing to timber (side fix connection). The wall ties through the slots would be to tie in the inner leaf and you can see the wall ties fixed to the angle face to tie in the outer leaf masonry wall.

The length of Tie B 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 inner wall (and the inner wall thickness). Should you require a tie pack with one side longer than the other as shown below, then you can order a mixed ties pack. You can also buy online additional tie pack and other accessory components.

WP3 Windposts – A channel system that sits within the cavity tying the inner and outer wall with wall ties, fixed at the base and top with brackets and cleats.

How does a UKLintels WP3 Windpost differ from Ancon | IG or Expamet (Birtley) Section Windpost?

Below shows in one easy to see table Ancon WP3 | IG U & Expamet U Section Windposts. It also shows the UKLintels system within this range of products. This table should be used as a guide only. Please check this table against the manufacturers latest published data for accuracy.

You can CONFIGURE ONLINE a WP3 windpost (85x60x6) section. Below is an explanation of how to use our online configurator with various tips for each stage.

The top connection will be a choice of fitting to attach to a timber, steel, or concrete beam. You can also download our PDF Installation guide.

Step 1 select your top connection bracket. 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. The various options are shown on screen and click NEXT once you have made your selection.

Step 2 you will decide on the length of the stem you will need. 2.5m – 3.5m stems come as one piece. 5.0m + options are two stems with a collar bracket connection. The collar bracket and bolts are supplied as part of the kit when you select these lengths and the stems are pre-dilled by UKLintels before delivery.

Step 3 – select your base connection. The stem is pre-drilled with a slotted hole to allow for adjustment. The base bracket bolts to the stem.

Step 4 – Various extension plates are also available to suit 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.

Step 5 – 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 can order a mixed ties pack. You can also buy online additional tie pack and other accessory components.

So, you have found out that you need windposts. Unfortunately, you cannot just walk down to your local builders merchants and buy as many as you need. Unless you come to UKLintels Windpost Superstore!

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?
Yes, order for Next day delivery from UKLintels Windpost Superstore

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.

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.

UKLintels are CE (UKCA) accredited for fabricated steelwork to BS EN 1090-1 to execution Class 2.

Did you know CE/UKCA Marking for fabricated constructional steelwork is a legal requirement? Don’t put yourself or your projects at risk. YOU are responsible as a purchaser of constructional steelwork to make sure the supplier you are using is CE (UKCA) compliant. Unfortunately, many small and medium sized steel fabricators still do not carry this accreditation putting many people at risk who purchase non-compliant constructional steelwork.

As of 1st July 2013 legislation, as a manufacturer or distributor of fabricated steel products, under the CPD, it is a legal obligation to adhere to the stringent requirements of BS EN 1090 and for the CE Marking of constructional steelwork. CE Marking ends on the 30th June 2025 in Great Britain. From then on, UKCA marking takes over. Failure to comply with BS EN 1090-1 is heavily penalised within the UK. Starting with suspension notices, application for forfeiture and prohibition notices. Failing to comply may also lead to fines up to £5,000, forced product removal and even imprisonment.

There is also a responsibility for anyone purchasing fabricated steelwork to make sure that they are purchasing from a certified CE (UKCA) supplier/manufacturer. Failure to purchase CE (UKCA) approved steelwork can lead to prosecution and rejection of products from Building Control which can be a costly process to remove and replace goods that were non CE (UKCA) accredited.

In order to achieve our accreditation UKLintels undertakes stringent control measures to comply with BS EN 1090-1 and are measured, audited and accredited by an external body; SCCS (Steel Construction Certification Scheme) who are a UKAS accredited Certified Body (subsidiary of the BCSA). This consists of criteria such as;

What does this mean? In essence UKLintels have total traceability of all elements that go in to the steelwork we supply. From our job specific work sheet we can clarify the source of the material used, the welding wire and gas used on your job along with many other control measures that result in you receiving CE/UKCA accredited steelwork to Exc. Class 2.

If you require constructional steelwork which is BS EN 1090-1 compliant, you can do so by browsing the associated products on our website covered under this standard such as Structural Steelwork | Windposts | Special Lintels | Steel Lintels | Thermally Efficient Lintels | Timber Post Supports | Coping Clips .

At UK Lintels, we have designed our own concept of Thermally Efficient Lintels. Which are the most cost effective and most available from stock, on the market!

What are they?

They’re an energy efficient type of steel lintel used in masonry cavity wall constructions. They provide support over the structural openings (doors and windows), whilst reducing linear thermal bridging heat loss compared to regular cavity lintels. Our own brand version is a split lintel solution. Split lintels are also the most thermally efficient lintel on the market with 0.010 Psi value (Catnic BSD & Angle) compared to 0.043 (Catnic one piece Thermally Broken Lintels).

Psi Value Image Source: Catnic Sept 2022 Product brochure & Separate Lintels Full Fill cavity Wall Construction Psi values 5-2-15. Split lintel data an example of using a Catnic BSD insulated & ANG angle lintel. UltraTherm lintels are am alternative to these two lintels.

What are the advantages of our UltraTherm Lintels?

Why use an UltraTherm Lintel?

Using an energy efficient lintel improves the thermal performance of the wall and focuses on the increasing proportion of heat lost through thermal bridges. Lintels can be a major thermal bridge in a building. Therefore, the lower the psi value, the better for the overall performance.

How can I improve the psi values?

Thermal Performance

Target fabric energy rates, target CO2 emission rates, and target primary energy rates for the foundations of the Building Regulations Part L 2021. They set the energy requirements for the new buildings and are all influenced by the performance of the fabric. Selecting a Thermally Efficient Lintel can play a significant role in reducing heat loss associated with thermal bridging.

Heat loss through the building fabric is expressed as a U value and measured in W/M2K, while heat loss via linear thermal bridges is expressed as a psi value and measured in W/Mk. The total fabric heat loss is the sum of the combined fabric U value multiplied by the total area, plus the product psi value of junctions and their total length.

Improving the thermal performance of the wall emphasises the increasing proportion of heat lost through thermal bridges in the building fabric such as lintels. Lintels can be a major thermal bridge in a building, and the lower psi value, the better for overall performance.

Buildability Myths of 2 piece lintels vs 1 piece lintel

There are some myths (created by the manufacturers of the product) that using split lintels isn’t as efficient for buildability purposes. We give some simple answers to those myths;

What we offer

In our Thermally Efficient Split Lintels we offer different duties (Standard, Heavy, Extra Heavy) and various inner/outer leaf sizes to suit your requirements.
