A double glazing window is made up of two panes of glass, separated by a bar and seals to create an airtight environment. The width between the two panes and the type of spacer bar used will determine its effectiveness to insulate and reduce outside noise.
The gap (cavity) is filled with dehydrated air to prevent condensation and improve insulation.
This unit is then inserted into a frame that should be thermally broken to stop heat and sound transfer.
Our windows are fabricated from high grade REHAU un-plasticised polyvinylchloride which is a pure form of PVC. See our sales process section for more information on the process.
