Things to decide before you order

Beads inside or out

Which windows first

Start with windows that can be reached without a ladder and are out of sight from the street. We can schedule the rest for later.

Rules that apply in England

England

Safety glass in critical locations

In England, section 5 of Approved Document K treats glazing in doors and in side panels within 300 mm of a door edge, from floor level up to 1,500 mm, and any other glazing below 800 mm, as a critical location. Glass there should break safely, be robust, or be guarded. Laminated or toughened glass meeting BS EN 12600 class 3 is the usual answer, rising to class 2 for door and side-panel panes wider than 900 mm.

Windows needed for escape

Approved Document B expects many habitable rooms in houses, particularly upstairs, to have an escape window with a clear opening of at least 0.33 m², at least 450 mm high and 450 mm wide, with the bottom of the opening no more than 1,100 mm above the floor. Changing the glass does not alter that, but locks, secondary glazing and film must not stop the window opening. Laminated glass is hard to break through, so escape always relies on the window opening.

Security glass for home windows in Barnet: questions

Do you cover Potters Bar as well as Barnet?

Yes. As well as Barnet, we can arrange surveys in nearby Potters Bar, Borehamwood and Finchley. Dates depend on installer availability.

Do I need new windows to get security glass?

No. If your frames are in good condition, we replace just the glass with laminated units made to fit them.

Will security glass make my home warmer or colder?

Choosing low-E glass, argon fill and warm-edge spacers usually matches or beats older units, so most people notice no change or an improvement.

Which windows do burglars target?

Mostly ground-floor windows at the back and side, and windows that can be reached from flat roofs or walls. Those are the ones we suggest upgrading first.
