Aluminium entrance doors for Harpenden jobs

For communal entrances to flats, access control is usually supplied and wired by a separate contractor. We can prepare the frame for an electric strike if you tell us the model.

Door closers, panic hardware and electric strikes affect how the frame is prepared, so they need to be decided before manufacture.

• Overhead or concealed door closers
• Toughened or laminated safety glass
• Low accessible thresholds
• Thermally broken or non-thermal aluminium sections

Regulations for jobs in Harpenden

Replacement external doors in England should meet a U-value of 1.4 W/m²K under Approved Document L. Glass in doors and side panels below 1500mm is a critical location under Approved Document K, so it must break safely (toughened or laminated to BS EN 12600), be robust or in small panes, or be permanently protected. Doors into new homes also need to meet Approved Document Q for security, which is usually shown with PAS 24. Replacing a door that is more than half glazed is notifiable building work, self-certified through a competent person scheme or approved by building control.
