Geo-Roofs®, 70 mm-thick panels (0.57 W/m²K)
EPD
Certificate type
Kalwall diffused natural daylighting Skylights. Man safe and OSHA fall through compliant.
Rooflight applications.
S-lines:
Budget friendly, flat curb-type skylights are available in standard 1′ increments, either 4′ or 5′ W, from 4′ to 20′ L. Units are curb ready, with factory sealed aluminum perimeters, for rapid install.
Pyramids:
Factory pre-engineered in three standard pitches, from 4′ to 20′ W, in even one foot increments. Pyramids are designed for rapid installation from the outside and may be removable.
Geo-roofs®:
A stunning and cost effective top lighting option, Geo-roofs® come from 8′ to 24′. Geos are a favorite in retail and lobby areas, as diffuse daylighting bathes areas below and showcases goods with perfect colour.
Features and benefits:
Kalwall is not a glazing panel but rather a structural sandwich panel with outstanding load capacity and structural integrity that polycarbonate systems
and insulated glass units (IGU) simply cannot match.
With a high strength-to-weight ratio, Kalwall panels are both strong and lightweight. This makes the installation process easier and reduces extraneous structural support framing, saving both time and money. All Kalwall systems are very low maintenance. The panel’s FRP faces have self-cleaning properties, are resistant to dirt and particulate build-up, and can handle harsh chemical and environmental exposure.
The panels block harmful UV-A and UV-B rays while transmitting the full spectrum of visible light for perfect colour rendition within interiors. With a wide range of translucent insulation options, Kalwall’s thermal performance reduces HVAC heating and cooling loads while harvesting daylight to cut artificial lighting usage.
Fibreglass Reinforced Polymer (FRP) Faces:
Kalwall has developed a full line of high performance FRP face sheets including the latest generation of Super Weathering (SW) formulations that are unrivalled in the industry. Along with a variety of high performance options, Kalwall offers both standard and optional colours and finishes in order to provide designers with more flexibility. Translucent White and Crystal FRP face sheets are standard. The four Kal-tints are optional. Optional FRP finishes are available for interior face sheets only.

Recyclability | Can be recycled - See guidance Manufacturer guidanceKalwall has a design life of 25 years with minimal maintenance. Made from Aluminium and FRP it is chemical and rot resistant. UV stable to full body depth, it will not yellow. The FRP facesheets are also engineered to incorporate a glass erosion barrier, preventing fibre bloom. The Aluminium frame is easily recycled, the FRP sheets can be separated and ground to a powder and added back into GRP production. |
Recycled contentAs defined in clause 7.8 of BS EN ISO 14021 | 95 % Manufacturer guidanceRecycled content can be up to 95% depending on configuration and speciation. |
