4mm x 20mm x 4mm hermetically sealed double-glazed units for better heat retention, sound insulation and less condensation to room glass.

“Swiss Spacer” bars on all glass units with warm edge technology to help prevent cold transfer and internal condensation between the panes of glass.

Pilkington “K” glass, soft coat low emissivity, to further reduce heat loss and to conform to new legislation.

Argon gas filled double glazed units which, when combined with the soft coat K glass, low iron coatings and Swiss Spacer bar achieves a “U” Value of 1.29W/m2, or a “U” value of 1.2W/m2 in triple glazed options.

Toughened safety glass to BS6202 class ”A” internal and external, for safety and added strength on all glazed doors and windows with internal cills below 800mm to comply with building standards.

70mm thick 5 chamber profile as opposed to 60mm thick 4 chamber profile for better strength, heat retention and slimmer width frames.

Low level glazing gaskets, not visible between frame and glass. No unsightly black rubber.

Internal glazing beads to prevent removal of glass units from outside for higher security.

All joints on frames high quality welded to prevent any air or moisture ingress.

Galvanised steel reinforcement to all frames and external sills to fix hinges locks etc. to steel inside the frame, no dropping hinges, not RCM plastic as found in the 4 chamber systems, this gives the systems a significantly longer lifespan with fewer problems throughout the life of the frames.
