UltraTherm Lintels

UltraTherm Lintels

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.
This lintel solution is in stock and available for Collection from our branch in Bristol, Next Day Delivery or Fast Track Delivery, Nationwide.
