Read All the Questions

Is double glazing worth it?

It makes a real difference to heat loss. A typical clear single-glazed aluminium window has a U-value of about 5.6 W/m²K; clear double-glazed aluminium is about 2.8 W/m²K. Low-e glass cuts heat loss further. Heat escapes through air leakage, conduction, convection and radiation.

Can you replace old steel or wooden windows?

Yes — it is called remove-and-fit. The existing openings are measured, new frames are made, the old frames come out by cutting their fixings, the new frames are fitted and fixed, and the plaster around them is patched. Painting is not part of the job, and tiles butted up against old frames can be damaged when the frames come out.
