Edwardian Roof sheets can be designed with polycarbonate sheeting or glass, though of course polycarbonate sheeting was not offered all through Edwardian times and as a result glass is a much more genuine product to make use of as the roof sheets, as well as having a perfectly better-quality performance depending on the glass requirement selected. Current advances in nanocoating expertise for glass have radically superior the heat maintenance performance of glass, so extraordinary care requires to be taken with the glass condition if the room is to be used all year round.
