Security secondary glazing in Swansea

What should security secondary glazing cost in Swansea?

Our guide range for security secondary glazing in Swansea is £594 to £1,794 including VAT (£495 to £1,495 plus VAT) per window, including fitting. The survey is free for new installations and your fixed price follows in writing.

Security secondary glazing is a separate slim window fitted on the room side of an existing window, glazed with laminated glass so it forms a second barrier. It leaves the original window untouched outside, which makes it a common choice for listed buildings, conservation areas and period sash windows.

Choices you can make

Colour-matched frames to suit the room
Fixed within the reveal, leaving the original window untouched
Low-E glass for better insulation
Laminated glass in slim aluminium frames
Locks and catches that open from inside without a key
Vertical sliding, horizontal sliding, hinged and lift-out styles

Fitting in Swansea and nearby

We can arrange security secondary glazing across Swansea, the main centre for West Glamorgan, and in nearby towns including Gorseinon, Port Talbot and Neath.

West Glamorgan centres on Swansea's city centre, SA1 waterfront offices and Victorian terraces, with the town centres of Neath and Port Talbot and Gower villages to the west.

Good candidates for security secondary glazing:

Listed homes and buildings in conservation areas
Ground-floor flats in converted townhouses
Offices in historic buildings
Homes on busy roads wanting noise reduction

Before the glass is ordered

Listed building consent

Internal secondary glazing is usually seen as reversible, but consent can still be needed. Check with the conservation officer first.

Escape and ventilation

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

Wales

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.

Replacing glass in an existing frame

Welsh Government guidance says building regulations have applied to replacement glazing since 1 April 2002, which covers replacing windows and doors. Swapping only the glass or a sealed unit in an existing frame is generally treated as a repair. New glass in a critical location should still be safety glass, and the council's building control team can confirm anything unclear.

Security secondary glazing in Swansea: questions

Which areas near Swansea do you cover?

We can arrange work in Swansea and in nearby Gorseinon (5 miles), Port Talbot (7 miles) and Neath (7 miles). Dates depend on installer availability.

Will secondary glazing cause condensation?

A well-fitted unit usually reduces condensation on the inner pane. Some ventilation of the gap may be needed, which we discuss at the survey.

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.

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.
