Frequently asked questions

Will commercial double glazing cut energy bills for a Londonderry business?
Yes - replacing single glazing or failed units with modern double glazing noticeably lowers heat loss and running costs for Londonderry premises.
Can you replace just the failed (misted) units?
Yes - where frames are sound we replace only the failed sealed units, which is faster and far cheaper than full window replacement.
What U-value should commercial glazing achieve?
Modern sealed units reach U-values around 1.0-1.4 W/m2K, helping meet Building Regulations Part L.
