Kömmerling windows and doors from Alex Trade

Kömmerling’s uPVC system is naturally insulating. Our windows achieve a WER rating of Grade C compliance without the need for costly warm edged Swiss spacer bar in the double glazed units. A-Rated windows are also available on request. Our standard double glazed units consist of 4mm Planitherm Total Plus glass, 20mm cavity with 90% Argon gas, standard aluminium spacer bar and 4mm float glass.

So, any combination of frame, colour, and reinforcement fitted with our standard unit is compliant. All the BBA inspectors in Cheshire and the wider region have a copy of our specifications together with the relevant B.F.R.C. simulation reports. This means they will be satisfied of compliance for any job of yours they may inspect.

Kömmerling profiles are all certified to BS7412, BS7413, PAS023, PAS024, and BS7950, letting you install with confidence.
