THERMAL EFFICIENCY (PART L)

Compliance with current Building Regulations is essential for every installation, and while it can sometimes be complex, we make it straightforward.

Our entire product range complies when used in conjunction with the correct glass specifications, delivering energy ratings for renovations when installed with a double-glazed unit that has a U-value of 1.2 W/m²K and a solar gain of 0.71 or better, using an Edgetech Super Spacer Bar or equivalent.

All our Casement Windows achieve an ‘A’-rating if the aforementioned glass unit is upgraded to low-iron glass. The thermal efficiency of the REAL Aluminium range can be enhanced further by using higher performance double-glazed or triple-glazed units.

The addition of low-iron glass will not improve U Values but will improve WER/DSER rating due to solar gain. The addition of triple glazing will improve U Values but due to reduced solar gain has limited effect on WER/DSER ratings.

FRESHER, CLEANER INDOOR AIR (PART F)

The new TTF Slimline is a through-frame trickle ventilator that is a robust, yet attractive aluminium ventilator. With its built-in updraught and various operating modes, the TTF Slimline is a stylish and effective product that perfectly complements our profiles.
