Glass and glazing
There are many glazing options for your windows and doors. We offer single glazing, slimline double glazing, double glazing or Fineo vacuum double glazing. If your property is listed this will restrict you to single glazing unless you apply for planning permission to change. In this process we can help with all detailed drawings for you to submit as part of your application.
We also offer many obscure/decorative glass designs which you may choose to have in your bathroom or entrance door.
Sound reduction can also be achieved with acoustic glazing. This is where we upgrade the outer pane of the double glazing to be thicker to achieve a better decibel rating. This is often for homes close to high traffic roads.
