Laminated security triple glazing in Crowthorne
If you live in Crowthorne (RG45) and want laminated security triple glazing, start with a free survey: every opening measured, then a written quote that fixes the price.

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 Crowthorne

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.
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.
