Glass Specification in Flat Rooflights

Over recent years there has been a huge surge in the popularity of modular rooflights which are widely specified for domestic and commercial projects – and with good reason.  There’s a range of excellent, very high quality examples available from reputable suppliers, all of which offer superb aesthetics and very high performance, with excellent U-values.
