Laminated security triple glazing in Harwich
From the first measure to the handover pack, we handle laminated security triple glazing for homes in Harwich and the rest of Essex.

Glass that cracks but stays in place, on the windows that need it. 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 Harwich
In Harwich, midday sun in late December sits around 15° high, with roughly 7 h 45 min of daylight. For windows facing north or shaded by neighbours, cutting heat loss matters more than solar gain; on open south-facing glass, ask about a higher solar-gain unit.

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.

Questions from Harwich
What does PAS 24 mean?
PAS 24 is a British test standard for the security of doors and windows against attack. We specify products tested to it.

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.
