Achieve a 0.15 U-Value with Confidence...

After a comprehensive review of U-value calculations across a wide range of commercially available insulation products, we found that many timber warm roof systems currently on the market do not achieve the U-value requirements set out in UK building regulations.

For this reason, we have tried and tested a number of alternative build-ups before ultimately settling on the Thermacore warm roof make-up, which reliably achieves the necessary performance requirements.

Achieve a 0.15 U-Value with Confidence...

After thoroughly reviewing U-value calculations across a wide range of available insulation products, we discovered that timber warm roof systems not using our specified materials consistently fail to meet the required standards.

For this reason, we have tried and tested a number of alternative build-ups before ultimately settling on the Thermacore warm roof make-up, which reliably achieves the necessary performance requirements.

High-Performance Insulation...

Every ThermaCore roof is pre-fitted with 90mm PIR insulation boards, one of the leading insulation solutions on the market, and pre-fitted with SuperFOIL SF40, a high-performance, multi-layer reflective insulation that acts as a 3-in-1 solution for thermal insulation, radiant barrier, and vapour control.

We use 12.5mm fol-backed plasterboard, with the foil backing acting as a moisture barrier, providing added protection and helping maintain a dry, healthy internal environment.

Get Answers to Your Questions...

What does a ThermaCore warm roof come with?

A ThermaCore Warm roof comes to site 80% complete, the only things you will need to complete the installation are fixings to fix the roof to the house wall, lead flashing and plaster to finish inside!

Can I get Installation Training?

Yes, we offer guided installs! We also have a technical helpline, so anytime you have a question, we have an answer!

Do your U-Values meet the regs?

Yes, we meet building regs for U-values in England, Wales and Scotland and we are prepared for the next increase due in 2025!

Wat makes the ThermaCore Warm Roof different from other roof systems?

Firstly, it’s made from timber so is up to 800 times less conductive than aluminium meaning there is no hot and cold bridging and no condensation issues. It has also been designed so no insulated-plasterboard is needed to hit the all-important 0.15 U-Value, so our roofs can be finished with a 12.5mm Plasterboard!

Do you offer different tiles?

The ThermaCore Warm Roof comes as standard with Britmet shingles or liteslates. Ther Low Pitch Roof is finished with our Low pitch roof sheets, but can supply different tiles if required (including concrete tiles if the supporting structure is strong enough for the additional weight)

How do I survey for one of your roofs?

Just like traditional conservatory, we base everything on internal frame sizes. It is always best to provide the correct pitch as well, but we can help with that!

Is it Building Control approved?

Every Thermacore Warm Roof has been independently tested and certified by LABC. We also handle all building control matters in-house, so if your project requires submission to building control, just let us know - we’ll take care of everything.
