Hambleside Danelaw have been manufacturing GRP rooflights in the UK for decades. Hambleside Danelaw have been focusing on improving building energy performance, while reducing the carbon footprint through the efficient and effective use of daylight.
Zenon GRP rooflights diffuse natural daylight throughout the entire building, which comes with a range of additional benefits, from reduced artificial lighting cost to the occupant’s health and welfare.
Hambleside Danelaw rooflights have been tested for safety in accordance with the requirements of ACR001 produced by the Advisory Committee for Roofsafety to ensure that the products supplied are non-fragile. Even when non-fragile, it is important to note that the rooflight assembly should never be walked on.
GRP and other rooflights used in ‘top-lit’ buildings such as industrial and commercial buildings are essential in delivering the most energy efficient buildings through the free and natural resource that is natural daylight.
Specifying Rooflights
When specifying rooflights there are some important things to consider such as:
- Light Transmission – this is the amount of light that passes through the rooflight to the interior of the building.
- Total Solar Transmission (or g-value) – this is the combination of the directly transmitted heat energy and the re-radiated secondary component that accompanies natural daylight.
- Thermal Transmission (U-value) – A measure of the flow of heat through an insulating layer or building material. The lower the u-value, the better the insulating function.
- Fire Performance – How a product responds and resists heat and fire, for more information on Zenon rooflight’s fire performance click here.
- Sound Transmission – Acoustic properties or sound transmission considerations in building design cover the methods by which sound transfer, from one part of a building to another, or from inside to out and vice versa, can be controlled.
- Non-Fragility – Specific to roofing, the term non-fragile refers to a roof assembly rather than any one component. This is a critical issue and assistance is available from all responsible rooflight manufacturers, as well as from RA (Rooflight Association).
By specifying the Zenon range of GRP Rooflights, building users can be confident in their specification of quality products delivering the benefits of natural lighting with minimised heat loss; benefits that can enhance the financial and environmental performance of the building in service and improve the internal environment and make it a more pleasant place to be.
