All thermal and compliance data. Published. No request needed.
U-value (W/m²K)
Spacer λ (W/mK)
U-values, psi-values, spacer bar conductivity, and regulatory certificates in one place. Specify with confidence; the numbers are here to check.
Data sheets and BIM objects. No registration.
Every file is available immediately. Data sheets carry full U-value tables, psi-values, and glazing configurations. BIM objects are IFC-compliant and dimensionally verified.
Aluminium Thermal Data Sheet
UPVC Thermal Data Sheet
BIM Objects — IFC & Revit
U-values by glazing configuration, psi-values at frame junctions, and load-test reference data for all aluminium profiles.
Multi-chamber section performance figures, weatherseal ratings, coastal exposure classification, and spacer bar conductivity values.
IFC-compliant and Revit-ready objects for all current profiles. Dimensionally verified against manufactured section geometry; no interpolated tolerances.
Certifications across UK regulations and European compliance
Part L — England & Wales
Section 6 — Scotland
CE Marking — European Projects
Thermal performance data includes Section 6 (2022) compliant U-value declarations. Psi-values at sill, jamb, and head are published for linear thermal bridging calculations.
CE-marked to EN 14351-1. Declaration of Performance documents are downloadable for each system, covering air permeability, water tightness, and wind resistance classifications.
All profiles meet Part L 2021 notional U-value requirements. Certified centre-pane and whole-window figures available for SAP and SBEM submissions.
