Zenon Pro

Zenon Pro is Hambleside Danelaw’s tried and tested range of traditionally reinforced GRP rooflights.  Manufactured at our ‘state of the art’ facility in Daventry, the rooflights are CE and UKCA marked and are profiled to match the building envelope cladding system.

With 100s of profiles available, our Zenon Pro rooflights can be used in new builds and refurbishment projects.

Zenon GRP rooflights are ideal for Industrial, Commercial or Agricultural Buildings

Made-to-order, our rooflights can be used in single, double or triple skin assemblies, with a choice between polycarbonate, or Zenon’s unique Insulator core for the intermediate layer.

Hambleside Danelaw are the first UK in-plane GRP rooflight manufacturer to achieve an independently verified Environmental Product Declaration from BRE, making a commitment to raising awareness of the embodied carbon content and environmental impact of our materials on the built environment.

Zenon Pro rooflights are available in all sheet weights defined in the UK Annex to BS EN1013 and when used in the right configurations offer a range of non-fragile solutions compliant with ACR[M]001.

Passionate about Daylight

Hambleside Danelaw are members of The Rooflight Association (National Association of Rooflight Manufacturers) and are passionate advocates of the beneficial impact natural daylight can have in the working environment.  Zenon Pro can be combined with our Insulator which forms a transparent ‘honeycomb’ cell structure perpendicular to the plane of the rooflight, for excellent daylighting diffusion.

This ‘honeycomb’ directs the reflectance aspect of the daylight into the building through the rooflight with minimal impact on the overall light transmission. The cell structure is of a lightweight high-gloss material designed to maximise reflectance and minimise absorptance to best effect, creating a ‘lens’ type effect.  This, combined with the glass fibres in the GRP rooflight which act as natural diffusers causing light to bounce through the Zenon Pro provides a better, wider spread of dispersed light.

Incorporating GRP rooflights into your design will bring the benefits of diffused light to your project, potentially reducing the energy costs associated with artificial lighting.  To learn more about Zenon’s Light Transmission properties, take a look at our dedicated brochure.

Increasing Thermal Efficiency

When developing or refurbishing a building, it is becoming increasingly important to consider the U-value of that build.  The U-value reflects the thermal transmission through the assembly.  The lower the U-value, the better the insulation.  Hambleside Danelaw provide a performance calculator which can be used to establish the U-value, as well as other key performance indicators for our Zenon rooflights.

All of Zenon rooflight assemblies can have thermal layers added, with Hambleside Danelaw’s Insulator being the perfect choice for low U-Values.  Made from cellulose acetate, a recycled wood pulp product and compostable at the end of its service, our Insulator provides U values that can far exceed the regulatory requirements.

Zenon rooflights combine an environmentally aware product with low U-v­­alue – making the Zenon Pro with Insulator a great choice for lower carbon embodiment and energy costs.  For a product with even lower embodied carbon and a GRP rooflight with high non-fragility, take a look at Zenon Evolution.
