In short

X-Pyramid Rooflights are provided as single units, which can be installed individually or in groups to fill an interior with natural light and create an attractive design feature. For projects that require a more architectural statement, X-Pyramids offer an elegant alternative to single-unit rooflights. These pyramid-shaped rooflights combine contemporary styling with outstanding daylight performance, transforming flat roofs into striking design features. Available in polycarbonate or glass, X-Pyramids deliver excellent thermal efficiency, durability and visual impact, making them ideal for both modern and traditional buildings.

X-Pyramid rooflights are designed for straightforward installation. They can be mounted directly onto the roof surface or fitted to an existing upstand, providing reliable weather protection and helping to seal the building envelope quickly. Interchangeable kerb options make alignment simple and ensure compatibility with all standard roofing membrane systems.

X-Pyramid Rooflights are provided with a 10-year warranty, and experts can offer support throughout design, specification and installation.

Functions and sizes

Product details

X-Pyramid is compatible with all commonly used roofing membrane systems and is suitable for installation on flat roofs as well as roofs with pitches of up to 15°.

A comprehensive range of interchangeable and interlocking kerbs is available, including vertical, splayed and adaptor options, allowing installation to suit different upstand designs and insulation depths. Kerbs can be manufactured from extruded uPVC, thermally broken aluminium, or aluminium for unheated applications.

This system removes the need for on-site construction of metal frames or timber supports. Vertical riser sections are designed to accommodate both flat board and tapered insulation, enabling a fully customised kerb height.

Glazing options

Glazing options include single-, double- or triple-skin polycarbonate, as well as double-glazed glass as a low U-value alternative, and a hybrid combination of polycarbonate and glass. Solid metal domes can also be provided.

Performance

Our dome rooflights have been carefully designed and tested to ensure they meet or exceed the necessary performance standards:

Thermal efficiency — Dome rooflights which meet the requirements of Building Regulations Part L.
Non-fragile — Classified as non-fragile and achieve Class B rating to ACR [M] 001:2014.
Fire performance — Dome rooflights have been tested according to BS 476 Part 7 and achieved a Class 1 rating.
Air permeability — 3m³/hr/m² at 50 pascals
Reaction to fire — Classified ad TP(a) and achieves Class B- s2, d0
External fire performance — Achieves B_ROOF(t4)
Fragility — ACR[M]001 Class B

They are also TP(a) rated, meaning the material self-extinguishes within five seconds after a flame has been removed.

Security options

VELUX Commercial offers a range of security options to prevent unauthorised access, depending on the level of security required and product selected.

Security screws

Thread assemblies into which the security screws locate are inaccessible.

Intruder grid

Intruder grid systems can be added to all dome rooflights. They are positioned between the glazing and the roof opening and consist of a 3mm diameter, solid steel fully welded mesh in a 75mm grid. This system will resist entry, even if the rooflight has been damaged or removed.
