What to check before ordering fire-rated windows in Darlington
Why fixed lights are common
An opening sash introduces gaps and hardware that all need testing. Fixed fire-rated windows are simpler and more widely available.
Ventilation
If a fire-rated window cannot open, ventilation may need another route. We coordinate with the designer.
Matching appearance
Rated windows can usually be finished to match the rest of the elevation.
