Made to Measure
We manufacture around the confirmed opening, configuration, colour, glazing and hardware specification.
Discuss your projectPrestige performance
Prestige doors use Sheerline Thermlock® multi-chamber thermal technology. Published thermal values vary by product and glazing; for example, Prestige glazed single and French doors can achieve published U-values of 1.4 W/m²K double glazed and 1.0 W/m²K triple glazed depending on specification.
Thresholds, security and glazing
Door performance is about more than the frame. Threshold choice, glass, locking, hardware, drainage and installation all need to work together. We can discuss these details before manufacture rather than treating every opening as the same.
