If you’re looking for Roof Domes in Watford, then Meridian Building Plastics is the place to go!
A great alternative for a flat glass skylight may be our range of dome-shaped polycarbonate rooflights. Due to how light interacts with a curved shape, more light will enter the room below and it will cover a larger area. This is because light that travels through a dome gets bent at a larger angle than it would through a flat glass panel! There will also be less glare and a more even distribution of light, too.
If you need to remove warm or stale air and replace it with a fresh air flow, you can choose to install a ventilation rooflight.
Manufactured to the highest standards, all of our polycarbonate rooflights and roof domes at Watford’s Meridian Building Plastics are designed to give maximum weather protection, UV protection and high impact resistance. You can choose between a clear, opal, diffused or bronze tinted glazing and from a range of shapes including pyramid and domed. Extruded from high-quality UPVC, it also has an integrated water management system to shed water to the outside of the rooflight. Whether you’re retrofitting a rooflight to an existing roof or building your project from scratch, we have the best range of polycarbonate rooflights in Watford!
All of our fixed and opening roof domes come with an upstand (kerb) included as standard, which is important for dissipating rainwater.
Fixed Roof Domes
These polycarbonate roof domes do not open, and therefore are only suitable for areas that just require natural light and no ventilation. If you require some form of ventilation, then you can add hit & miss vents or rotary vents to the upstand directly.
Opening Roof Domes
These domes can be opened to approximately 300mm and are the same as our fixed dome rooflight in every way apart from the wormgear mechanism that opens them. The smoothest & quietest of the available gear systems, the wormgear mechanism is operated at ground level by hand with a telescopic handle (not included). This dome is the perfect option for rooms that require regular and consistent periods of ventilation.
Dome Only Rooflights
Dome only rooflights are supplied without the upstand, and are intended to be used when replacing an existing dome lid or when building your own upstand.
