Security double-glazed units in Hatfield

How much should I budget for security double-glazed units in Hatfield?

Budget £174 to £594 including VAT (£145 to £495 plus VAT) per unit for security double-glazed units in Hatfield, supplied and fitted. Larger panes, thicker makeups and difficult access cost more; the price is fixed in writing after the survey.

A security double-glazed unit is a sealed unit in which one or both panes are laminated glass, usually the inner pane, so the window keeps its insulation but resists being broken through. It fits the same frame as a standard unit and is the simplest way to add security to modern windows and doors.

What to think about first

Which pane is laminated

Laminating the inner pane is the usual security choice. Laminating both panes adds protection on high-risk elevations.

Internal or external beads

If your beads are on the outside, we add security tape or clips so the unit cannot be lifted out after the beads are removed.

Consents and safety: 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.

Security rules for new homes

Approved Document Q has applied to new homes in England since 1 October 2015. Easily accessible doors and windows, meaning any part within 2 m vertically of the ground or another accessible surface, should meet PAS 24 or an equivalent, and glazing in doors and in windows within 400 mm of a door should be laminated to at least BS EN 356 P1A. It does not apply when you change the glass in an existing home, although it is a sensible benchmark.

Security double-glazed units in Hatfield: questions

Can you survey in Hatfield and nearby towns?

Yes. Surveys in Hatfield, Welwyn Garden City and St Albans are booked around installer availability.

Will a laminated unit be heavier?

A little. A laminated pane weighs about the same as a solid sheet of the same thickness. On large opening sashes we check hinges and friction stays.

Which pane should be laminated?

Usually the inner pane, so smashing the outer pane does not create an opening. On doors and low panes the outer pane is normally toughened to meet safety rules.

Do security units reduce noise?

Laminated glass already damps sound better than plain glass, and acoustic interlayers improve it further, which helps on busy roads.
