Steel Security Doors in Northwood
Steel security doors are an increasingly common sight on Northwood’s Arts & Crafts and period homes, where homeowners want front-door security that matches the value of their property across the HA6 postcode. Gerda doors carry BS EN 1627:2011 RC2 certification (with the RC3 upgrade available on Optima and Thermo Premium) plus 17-point locking and a 1.5mm galvanised steel skin against sustained forced entry. SteelR doors offer BS EN 1627:2011 RC4 single-leaf unglazed certification, Secured by Design accreditation, and a more contemporary aesthetic. Both systems are available in 200+ RAL colours and heritage panel designs that suit period Northwood front elevations. The insulated steel core (U-value from 0.8 W/m²K) also eliminates the cold bridging and draughts common with older timber and composite doors. Vitrum Solutions surveys Northwood homes throughout the area, including near Northwood Golf Club and Ruislip Woods (adjacent). Properties inside the Northwood Conservation Area need London Borough of Hillingdon approval for replacement glazing. We handle that liaison as part of every quote.
