Frequently asked questions

Is secondary glazing good for reducing noise in Cardiff offices?
Yes - a well-sealed secondary unit with a wide air gap can cut traffic and rail noise in Cardiff 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.
Are you insured for commercial glazing in Cardiff?
Yes - we carry full public liability insurance for commercial glazing work in Cardiff and across South Wales, and can provide details on request.
