Triple Glass
Super Insulating Door
Do the environment and your heating bill a favour and fit super insulating doors with triple glass.
Triple glass can be delivered with an U-value down to 0.5 (a normal double glazed super low E glass has an U-value of 1.1). With the triple glazed unit you can save up to 30-60 % on your heating bill, depending on the general insulating level of your house.
We supply a wide range of both classic and modern style doors. The Danholm systems contain outward opening entrance doors and french doors. All types are combinable with head lights and side lights in one or more items.
