Bifold doors fold concertina-style to open up entire walls onto patios and gardens — the defining feature of modern kitchen-diner extensions. S&K Glazing installs Smart Systems Visofold, Reynaers and Origin aluminium bifolds, plus Liniar uPVC bifolds, in configurations from 2-panel to 7-panel openings up to 7 metres wide.
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.
We check structural opening, threshold level and floor finish to specify track, threshold type (flush, rebated or weather-rated) and panel configuration.
Choose number of panels (2-7), opening direction (left, right or split), traffic door position, colour and glass specification.
Origin bifolds: 1-2 week lead time. Smart Systems and Reynaers: 3-4 weeks. uPVC bifolds: 3-4 weeks.
