With so many advantages it’s no surprise that double glazed sash windows are becoming an increasingly popular choice for period property refurbishment projects. It’s a far simpler solution to replacing sash windows, especially for listed buildings where timber effect window and glazing options are limited.
What is double glazing for uPVC timber effect windows?
Double glazed sash windows incorporate two panes of glass that trap a layer of air or gas, which is a natural insulator. This high-performing method means that the draughts are kept out of your home whilst the warmth is retained, meaning your double glazed windows will significantly improve your homes’ energy efficiency and could even save you money on your heating bills. This is a much more modern alternative than older sash windows with single glazing or secondary glazing can offer.
Double glazing is classed with different window energy ratings, G being the lowest and A providing the highest levels of thermal performance. Charisma Rose and Heritage Rose sash windows can be designed with double glazing that achieves energy ratings of C, B or A.
