Double Glazing (SIG Units)
Sealed Insulated Glass Units (SIG’s) are manufactured from two or more panes of glass held apart by a spacer and bonded with a hermetic seal, trapping dehydrated air between the glass panes.
- Improved resistance to wind-loads
- Improved thermal insulation
- Improved solar energy control
- Minimized condensation
Warm Edge Spacer
National Glass Distribution manufactures SIG Units using flexible spacer bars and promote “Warm Edge Technology”, which contributes to energy efficient buildings. Our spacer performs 8% better than the traditional aluminium spacer
