The six chamber design of your uPVC profile traps the heat in your home more naturally, which boosts your home’s energy efficiency. Adding to this, this will help you to cut the cost of your energy bills in the long run – homeowners have the option to have triple glazing fitted in their new patio doors. Our selection can reach U-values as low as 0.8 – so what are you waiting for?

Slim Sightlines

Our patio doors have particularly slim sightlines that allow them to hold onto much larger panes of glass compared to many conventional designs. This makes it the perfect choice for homeowners who want to increase the natural lighting that passes through their homes. Our selection of patio doors will help create an ambient living space throughout the year and remember that you never have to compromise on looks or design.
