How we specify aluminium windows here
Thermally broken extruded aluminium, meaning a polyamide barrier separates the inner and outer faces so the metal does not conduct heat straight out of the room. Powder coated finish rather than a foil. Rigid frames that resist flexing at the lock point, multi point locking and laminated glass options. The stiffness of the frame is itself a security property.
- Thermally broken profile only, we do not fit non broken aluminium in habitable rooms
- Powder coated finishes in the full RAL range including matt black and anthracite
- Same 10 year insurance-backed guarantee and our own fitters
- Roughly double a comparable uPVC window, which is why most homes we work on use aluminium selectively at the rear and uPVC elsewhere.
