Double & Triple Glazing

All of our uPVC windows are available in triple glazing as well as double glazing. 

With home energy bills continuing to rise it’s no surprise that Triple Glazing is becoming an increasingly popular option that more people are asking about. 

Not only is there improved energy efficiency and warmth, triple glazing also greatly improves sound reduction.

Sapphire Windows products come with a huge range of glass design options. From obscured patterned glass, leaded designs, Georgian bars, coloured glass and bevels, the options are limitless.

Visit our Glazing page for further information on the choice of glass available. 

"Around 40% of heat loss in the home occurs through standard single pane windows. Double glazed windows substantially reduce heat loss."
