Looking for composite doors in Belfast? S&K Glazing has been installing across County Antrim for over a decade. Composite doors combine a solid timber core, GRP outer skin and high-density polyurethane foam insulation — making them stronger, more secure and more energy-efficient than any single-material door.

S&K Glazing installs Solidor, Rockdoor and Door-Stop composite doors with multi-point locking, anti-snap cylinders and a 25-year colour warranty.
Belfast's Victorian and Edwardian terraces, the modern Cathedral Quarter regeneration, and the post-Troubles commercial expansion drive glazing demand across BT1-BT17. Heritage sash restoration, commercial shopfronts, and large-volume re-glazing on the urban estates all feature in our Northern Ireland workload.
For doors and glass extensions in Belfast, residential property style typically drives the design brief across Northern Ireland — whether that's contemporary aluminium bifolds spanning a garden-facing rear elevation, slim-frame sliding doors that maximise glass area on a modern extension, or heritage French doors fitted to a period façade. Most commonly we're working across BT1 and BT17 postcodes. Typical lead time from survey to install: 4-6 weeks for standard configurations, 8-10 weeks for bespoke or large-span builds.
