Description

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:

  • Aluminium or thermally-broken Grid Core composed of a series of interlocking I-beams.
  • Interior shatterproof FRP faces are formulated to meet interior finish, flame, and smoke requirements of the toughest international codes.
  • Translucent Insulation options, including Cabot’s Lumira® aerogel offer exceptional thermal properties.
  • Colour stable FRP face sheets with a permanent glass veil erosion barrier to eliminate fibre bloom.
  • Clamp-tite™ aluminium fastening system, specifically engineered and available as either standard or thermally-broken with many finish options.
  • Properly maintained Kalwall Skyroofs and Skylights can be walked on without risk of fall through. Tested to ASTM E661, Kalwall exceeds OSHA 1910.23 without the need for additional protection like external screens or fixed railings.
  • The shatterproof, super-weathering FRP face will withstand a 70 ft-lbs (95 J) impact. Optional high impact FRP faces will withstand 230 ft-lbs (312 J) impact by UL 972; also rated for windborne debris protection up to large missile D.
  • Complimentary Daylighting Analysis available, consult the manufacturer for details.
  • UL and FM approved.
  • CE / UKCA marked.
  • For U-values, light transmission and G-values consult technical literature (varies depending on type, thickness and exterior face colour).


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 guidance

Kalwall 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 content

As defined in clause 7.8 of BS EN ISO 14021

95 %

Manufacturer guidance

Recycled content can be up to 95% depending on configuration and speciation.
