Uw — thermal transmittance of the whole window (frame + glass unit), for a 1.23 × 1.48 m window with the best glass unit for the system. The exact value depends on size and glazing — we state it in the quote. * calculated by us to EN ISO 10077-1.

Uf is the thermal transmittance of the frame only. The Uw value for the whole window depends on the glazing and dimensions.
Reference test AEV: 1.23 × 1.48 m, 2 sashes. Thermal insulation depends on the combination of profiles and the thickness of the infill.
