Celsius Performance GlassWhether large or small, simple or complex, sheltered or exposed, Celsius glass delivers the ideal balance of solar control and high visibility.

For walls and roofs, K2 uses Celsius high performance glass. Engineered specifically for use in conservatories, Celsius glass has a unique micro-coating which enables it to block excessive heat from the sun and reflect heat from inside the home back inside. Celsius delivers the ideal balance of solar control and high visibility, blocking more damaging UV than typical sunroom glass while still allowing the visible light to stream in.

Additional Benefits:
Available in Blue, Grey, and Bronze roof tints
Utilizes warm-edge technology
Safety tempered roof glass
Rainfall and traffic noise are reduced by over 100% when compared to 25mm polycarbonate

For roofs, K2 also offers an alternate material: Silver/Opal IR Reflective Heatguard, a multi-layer 25 mm polycarbonate offers exceptional strength, thermal performance, and structural integrity when used in conjunction with a proper conservatory roof system.

PolycarbonateThis unique system delivers a wonderful balance of solar reflectance, insulating value, and light transmission. The soft glow of the opal interior gives the room an open and airy feeling while keeping glare and solar heat gain to a minimum. In addition, the silver exterior looks great in any design and reduces the visibility of dirt and debris that may collect on the exterior of the roof.
