Security and safety glazing in one triple unit. Laminated security triple glazing uses a pane made of two sheets of glass bonded to a plastic interlayer, so it cracks but stays in place when hit.

Winter light and glass choice in Carlisle

Winter days in Carlisle are short: about 7 h 11 min of daylight on 21 December, with the sun peaking near 12°. That low angle reaches deep into south-facing rooms, so we match the glass to each elevation rather than using one spec for the whole house.

Rules for security glazing in England

England requires replacement windows to achieve 1.4 W/m²K, or a Window Energy Rating of band B or better, which good triple glazing passes comfortably. Replacement windows are a controlled fitting. A competent person scheme installer (such as FENSA or Certass) self-certifies the work and notifies the council within 30 days; otherwise a building control body approves it.

Before ordering: Replacing windows on a house is normally permitted development if the new ones look similar. New upper-floor windows in a side wall must be obscure glazed and fixed, or open only above 1.7 m. Flats and maisonettes have no householder permitted development rights, so a change that alters their appearance needs planning permission. An Article 4 direction in a conservation area may mean permission is needed, and listed buildings need listed building consent.

How it works

We start with a survey, not a sales pitch: measurements, the structure above any bays, trickle-vent needs and escape windows. The quote that follows fixes the price, and anything unexpected on the day is agreed with you first.

Questions from Carlisle

Is laminated glass the same as toughened?

No. Toughened glass shatters into small blunt pieces; laminated glass cracks but stays in one sheet. Both are safety glass; laminated is better for security.

Do I have to have security glass?

Not for replacements, but it is worth it on ground-floor and easy-access windows.

Do you fit laminated security triple glazing in Carlisle?

Yes. We arrange surveys and fitting in Carlisle and across Cumbria. Send your postcode and the windows or doors you want replaced, and we will book a free survey.

Do I need permission for laminated security triple glazing in Carlisle?

In England, like-for-like replacements on a house are normally permitted development; flats need permission if the change alters their appearance, Article 4 areas may need permission, and listed buildings need listed building consent. Check whether your street is in a conservation area or covered by an Article 4 direction before changing the style.
