| Do the environment and your heating bill a favour and fit super insulating doors with triple
glass from Vrogum.
Triple glass can be delivered with an Ug-value down to 0.5 (a normal double glazed super low
E glass has an Ug-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.
On the basis of the Old Danish craftsman traditions - combined with modern technology
- Vrogum has developed these high insulating outward opening door systems in order to be
able to supply the demand of the customers today.
Vrogum offers a number of combinations in both classic and modern style. The Danholm
system contains outward opening entrance doors and french doors. All types are combinable
with head lights and side lights in one or more items.
