In short

X-Glaze is a bespoke single unit rooflight which can transform a dull room by flooding the space with natural light from above. Due to the glass top construction the light incidence is maximised, meaning that the light area is equal to the hole in the roof. X-Glaze consists of a glass top unit and a wooden upstand and is available as a fixed or comfort venting unit.

Product details

Functions and sizes

X-Glaze Rooflights are made to measure and can be configured, manufactured and delivered in bespoke sizes for specific requirements. They are also available in a range of standard sizes suitable for installation between 0–15° roof pitches. All units are supplied with a CWCT Class 2 laminated inner pane as standard for safety.

Walk-on rooflights

The X-Glaze Walk-on is a variant of the X-Glaze, designed to meet the floor loadings of a project. Ideal for accessible roof areas, it is available in bespoke sizes and loadings, offering both functionality and safety for walkable surfaces. Perfect solution when natural light is required beneath an accessible roof. It is manufactured with a 30 mm (2×15 mm or 3×10 mm) outer pane.

The rooflights comply with CWCT Class 0 for unrestricted access roofs and are designed to BS 6399-1 to withstand:

3.0 kN/m² UDL (Uniformly Distributed Load)
2.7 kN point load (commercial loads)

Slip resistance options include fritted dots or a deep sandblasted finish. Frames are polyester powder coated to any standard RAL colour range

Glazing options

X-Glaze can be designed with double or triple glazing units with the following features:

Toughened outer glass. For Walk-on, toughened and three-layer laminated glass (EVA foil) with step
Laminated inner safety glass. Class P4A for burglary-resistant glazing
Warm edge spacer (protects insulation properties over time and minimises the risk of condensation at pane edges)
Sun protection coating (optional)
Optional anti-slip for Walk-on
The glazing unit is glued into the aluminium frame with a UV resistant silicone
The glazing unit has a 115mm black silk print along the edge of the rooflight preventing thermal breakage

Performance

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

Air permeability — 3m³/hr/m² at 50 pascals
Reaction to fire — achieves B_ROOF(t4) in accordance with EN 13501-5
External fire performance — Achieves B_ROOF(t4)
Fragility (Standard X-Glaze) — CWCT Class 2 as standard, CWCT Class 3 or fragile glazing available upon request
Fragility (Walk-on) — CWCT Class 0

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