Laminated security triple glazing in Thornaby-on-Tees
We arrange surveys and fitting of laminated security triple glazing in Thornaby-on-Tees and the TS17 area, with a written, fixed quote after a free survey.

Laminated panes, multi-point locks and PAS 24 tested frames. 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.

Rules for security glazing in England
The rules for replacement windows in England are set by Approved Document L (2021 edition, with 2023 amendments): 1.4 W/m²K, or a Window Energy Rating of band B or better. 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.
Planning: 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.
- Free survey and a written quote fixed for the specification

Questions from Thornaby-on-Tees
Do I have to have security glass?
Not for replacements, but it is worth it on ground-floor and easy-access windows.
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.
