Product Description

Transform your home or commercial property today with our Framed Rooflight Infinity Glass 400 x 400.

If your home or office lacks natural lighting, stop wasting energy on artificial lighting and invest in beautiful, framed rooflights. These are designed to sit perfectly on flat or low-pitched roofs, improving both kerb appeal and the convenience of your daily routine. 

Despite its compact size, our 400 x 400 rooflights offer reliable thermal insulation and efficient lighting, making any room feel more expansive and airy. Designed from 6 mm double-glazed, toughened safety glass, our rooflights are argon gas-filled for improved heat retention. 

UV glazing helps to prevent distracting glares and protects your furniture from fading. The glazing has a U-value of 1.2 W/m²K and is fully compliant with BS EN 1279 standards. All of our 400 x 400 skylights include a dark grey frame with a durable thermal break, providing consistent indoor temperatures by minimising heat loss and draughts. 

It’s also highly resistant against harsh winds, leaks, and heavy forces, keeping your property safe throughout every season. 

Key features:

  • Double-glazed, argon-filled glass and a low-E coating, which reduces heat loss and limits solar glare.
  • Compact 400 × 400 mm size, ideal for small rooms, hallways, and work areas.
