Things to decide before you order

Escape and ventilation

On windows used for escape, the secondary glazing must open quickly from inside without a key or tool.

Frame colour and sightlines

Slim frames that line up with the existing meeting rails make the secondary glazing almost invisible from outside.

Rules that apply in Wales

Wales

Planning permission

In Wales the local planning authority decides whether a new or altered shopfront needs planning permission. Replacing glass in an existing frame usually does not, because the outside of the building looks much the same. Bollards or barriers on the pavement need consent from the highway authority, normally the council.

Windows needed for escape

Approved Document B for Wales sets out escape window provisions for homes broadly in line with England's, including minimum clear opening sizes and a maximum sill height. New glass does not change those, but locks, secondary glazing and film must leave an escape window able to open. Laminated glass is not designed to be broken out.

Security secondary glazing in Llantwit Major: questions

Which areas near Llantwit Major do you cover?

We can arrange work in Llantwit Major and in nearby Bridgend (8 miles), Barry (9 miles) and Porthcawl (11 miles). Dates depend on installer availability.

Can I still open my sash windows?

Yes. Secondary glazing slides, hinges or lifts out so the original window can be opened and cleaned.

Is secondary glazing safe for escape windows?

It can be, as long as it opens quickly from inside without a key. We design catches and handles for that.

Do I need permission for secondary glazing in a listed building?

It depends on the building and the council. Internal secondary glazing usually has less impact than replacement windows, but listed building consent may still be needed. Ask the conservation officer before ordering.
