Sub-1.2 W/m²K. No site adaptation required.

Multi-chamber UPVC profiles with installation-ready geometry. Thermal performance and coastal-rated weatherseal assemblies documented before the first frame is ordered.

/ Transparent Technical Data

Three performance parameters. All published.

Frame U-Value

Weatherseal Rating

≤ 1.2 W/m²K

Class 4 / E1500

UK Masonry-Ready

Achieved across all standard profile depths. No additional insulation inserts or site-applied thermal breaks needed to meet Part L compliance.

Gasket and seal assemblies rated for salt-air exposure. Test certificates are part of the standard technical pack — not available on request only.

Profile tolerances pre-engineered for standard UK brick-and-block openings. On-site adjustment time is measured in minutes, not hours.

▸ Installation-Ready Geometry

Engineered for the opening. Not the other way around.

Frame dimensions are toleranced to standard UK masonry reveals. No custom packers, no on-site profiling — the section drops in and seals first time.

Coastal-rated gasket assemblies are pre-fitted at manufacture. Salt-air exposure class is documented in the technical pack, not listed as a feature claim.

Full section drawings, gasket specification references, and fixing centre schedules are included in the downloadable technical pack.
