Emerald use precision cut uPVC profile supplied by Duraflex on all of our products. It is cut using the most up-to-date high-tech computer controlled machinery. All Emerald products are extruded from 100% virgin compound and are not diluted by second or more generation reground extrusion profile.
The glass forms the inner pane of a double glazing unit, with its coating facing the cavity. The coating reflects longer wavelength heat from radiators and room surfaces back into the building. Meanwhile it allows in warming short wavelength solar energy. Conveniently, these short wavelengths of solar energy are re-radiated by internal building surfaces as longer wavelengths, which are then reflected by the coating back into the room.
Our high quality compound windows remain retain their original pristine colour and will not become discoloured over time like some of our rivals' inferior quality products.
