Ritchlight Ultra, a major new development in architectural rooflights by market leaders Brett Martin Daylight Systems, introduces a fully thermally broken frame for the first time in any skylight system.

The addition of a thermal break in the Ritchlight Ultra’s kerb splits the aluminium structure of the high-performance roof light into internal and external components. For the first time this provides a roof light with a frame which matches the performance of the glazing, which is available in a range of options which enable specifiers to achieve U-values up to 1.1 W/m²k – exceeding Part L Building Regulation requirements by 50%.

• Thermally broken kerb
• Powder coated to match any RAL colour
• 20-year guarantee against leakage
• Available in glass or structured or solid polycarbonate
• Can achieve U values as low as 1.1
• Cost-effective runs of unrestricted length, up to a five-metre span
