Glazing Options
All of our windows and doors come with high-performance double glazing as standard, with triple glazing available on selected products for enhanced insulation and energy efficiency.
We offer a variety of ways to tailor your glazing specification, including options for upgraded glass types, spacer bars, and gas fillings. To enhance privacy without compromising on style, we provide a wide selection of obscure glass from Pilkington, each with its own unique texture and level of opacity.
For composite doors, each manufacturer offers their own distinctive glazing designs, ensuring a seamless match with the door style. If you’re considering a specific door, we’re happy to guide you through the available glass options.
Colours and styles change regularly and you should always check with the Team Frames branch on the availability. Above is a small sample of what we can offer.
