Glazing Options

Performance meets aesthetics

From heritage slimline units to high-performance triple glazing, we specify glass to suit your property, budget, and location.

If you're coastal or exposed…

Consider acoustic laminated glass to reduce wind noise, and marine-grade hardware for salt-air protection. Triple glazing offers maximum wind resistance.

The details that matter

Choose from heritage brass fittings to sleek contemporary locks. All hardware can be colour-matched to your chosen finish.
