01
Interfaces matter
Profiles, joints, fixings, thermal bridges and assembly details all affect whole-panel performance — so THOM tests the assembled panel, not just the materials.
Thermal Performance
Two thermal configurations. One engineered platform.
THOM’s basic configuration targets c. R50. A 65 mm high-performance configuration targets up to R110. Both are built on the same controlled panel platform — with final whole-panel performance subject to accredited validation.
Thermal architecture
The number belongs to the whole panel.
Materials are not the same thing as a finished envelope. Profiles, joints, fixings, interfaces and thermal bridges all contribute to the final result.

Whole-system performance
Test the assembled envelope — not the material datasheet.
The controlled configuration is the unit of evidence, so published performance can be tied to the exact product version tested.
01
Why whole-panel testing matters
Materials are not the same thing as a finished envelope.
02
One platform, two tiers
Basic and 65 mm high-performance variants share the same engineering ecosystem, so thermal specification can be matched to the application without re-qualifying a new system.
03
Controlled configuration
Each variant is represented by the exact product version and test configuration to which any published result applies.
02
What it means for the building
Low U-values translate directly into lower running cost and lower carbon.
01
Lower heat loss
The c. R50 design target corresponds to an indicative U-value of approximately 0.11 W/m²K; realised whole-panel performance remains subject to accredited validation.
02
Smaller plant
Reduced peak demand supports smaller, lower-cost heating and cooling systems.
03
Future-proof compliance intent
The design targets are intended to support performance beyond current UK Part L and Future Homes Standard thresholds, subject to final validated specification and project-specific compliance review.
c. R50 and up to R110 are current design targets for the basic and 65 mm high-performance configurations respectively; they are not certified whole-panel results. Accredited whole-panel validation is underway.
