Frequently Asked Questions
How does double glazing offer security?
With high-quality double glazing, it is possible to enhance the security and strength of your PVCu flush sash window. Double glazing consists of two panes of glass that are layered on top of each other. The gap between the layers of glass is filled with argon gas. This is in contrast to normal window glass which consists of a single layer of glass.
Double glazing naturally offers enhanced security as it is more difficult for intruders to break through two layers of glass instead of one. Triple glazing also offers enhanced security using the same method but with three layers of glass instead of two.
Are your PVCu flush sash windows suitable for conservation areas?
Generally speaking, yes, our flush sash windows are indeed suitable for conservation areas. If you perhaps have a new build in a conservation area, then this may make our PVCu flush sash windows the ideal window solution.
As the name suggests, our PVCu flush sash windows have flush external frames and contours. This specific shape and style meet the requirements of most conservation areas. It is always worth checking with the local planning or conservation officer as it may differ from office to office.
