How does Triple Ultra Low-E work?
6 layers of thermal and acoustic protection, each with a precise role.
Outer glass
Tempered, with Ultra Low-E coating on the inner face. Reflects thermal radiation back to the exterior.
Chamber 1 - Argon
16-18mm space filled with argon, which insulates 3x better than air.
Middle glass
Laminated and tempered glass with Low-E coating on both faces. Central thermal barrier.
Chamber 2 - Argon
The second argon chamber completes the insulation. Heat-soaked edges for maximum durability.
Inner glass
Tempered glass with Ultra Low-E coating on the outer face. Reflects interior heat back into the house.
SWISSPACER Ultimate
PHI-certified warm-edge spacer that eliminates the thermal bridge at the glass edge.
