Application

Kalwall Skyroofs provide top lighting solutions for any daylight space.

Description

Flat or curved, these systems span up to 7.625 m offering the ultimate in energy-efficient, diffuse daylighting. Designed to withstand hurricane-force winds and high snow loads, all are OSHA fall-through compliant. 70 or 100 mm thick structural sandwich panel system over a substructure (by others).


Kalwall panel standards widths are 1224 mm (4ft), 1520 mm (5ft) Maximum width is 1520 mm (5ft). Panel lengths between 914 mm and 6096 mm. Note: please check spans with Structura UK Ltd.


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.
