Innovative Daylighting Solutions for Superior Building Performance
Structura UK is the exclusive UK and Ireland partner for Kalwall® translucent daylighting systems, supplying high-performance skylights and skyroofs that deliver evenly diffused, glare-free natural light with market-leading insulation, strength and durability.
Our Kalwall systems are engineered to integrate seamlessly with commercial, institutional, industrial and public buildings, enabling enhanced occupant comfort, reduced energy use and standout architectural impact.
What Are Kalwall Skylights and Skyroofs?
Kalwall skylights and skyroofs are high-performance translucent roofing solutions that admit natural light from above while controlling glare, heat gain and thermal transfer. They combine advanced panel engineering with robust structural systems, giving architects, designers and building owners an outstanding toplighting option for any scale of building project. These products bring daylight deep into occupied spaces while ensuring comfort and energy performance beyond that of conventional glazed systems.
Kalwall Skylights are available in a selection of pre-engineered formats, including flat and pyramid units, designed for rapid installation and efficient on-site assembly with minimal disruption.
Kalwall Skyroofs® include factory-made geo-domes, long-span pre-engineered assemblies and bespoke roofing installations, all delivering superior insulation, diffuse daylight and extremely low maintenance performance.

Frequently Asked Questions
What makes Kalwall Skylights better than traditional glazed systems?
Kalwall offers highly diffused natural light, superior thermal insulation and greater impact resistance compared to standard glass rooflights.
Can Kalwall Skylights be walked on safely?
Yes. Properly maintained Kalwall skyroofs exceed OSHA fall-through safety requirements without external fall protection.
How does Kalwall improve building energy performance?
Kalwall’s translucent insulation and low solar heat gain help reduce heating and cooling loads throughout the year.
Are bespoke Skyroof shapes available?
Yes. Kalwall skyroofs can be configured in bespoke forms including domes, curved spans and integration with other roof glazing.
What maintenance do Kalwall Skylights require?
Weather-resistant panels require minimal maintenance, with rainwater typically keeping surfaces clean due to self-cleaning properties.
