Often Asked Questions (FAQ)
Does secondary glazing require preparation consent?

This consists of most Grade II noted structures, though it is always a good idea to inform the local preservation officer.

Can secondary glazing prevent condensation?
Yes. Condensation takes place when warm, damp air hits a cold surface. By developing a thermal barrier, the inner pane stays closer to space temperature, which considerably lowers the likelihood of condensation forming on the glass.
Is DIY secondary glazing a feasible alternative?
There are DIY kits available, usually including plastic (acrylic) sheets or magnetic seals. While cheaper, these do not provide the very same durability, visual appeal, or soundproofing capabilities as expertly set up aluminum systems. Professional quotes consist of the benefit of top quality glass and precision fitting.
