Frequently asked questions

Is secondary glazing good for reducing noise in Welwyn Garden City offices?
Yes - a well-sealed secondary unit with a wide air gap can cut traffic and rail noise in Welwyn Garden City premises by up to around 80%.
Can secondary glazing go on listed buildings?
Yes - because it is internal and reversible, secondary glazing is widely accepted on listed and conservation-area buildings.
Does secondary glazing help with heat loss?
It traps a still layer of air against the existing glass, sharply reducing heat loss and draughts.
