Rooflight Factory Flat Roof Skylight – Compact, Durable, and Energy Efficient

Bring natural light into your home with the Rooflight Factory Flat Roof Skylight, a sleek and durable solution designed for modern living spaces. This high-quality triple-glazed skylight enhances energy efficiency, provides exceptional thermal insulation, and ensures long-lasting performance – ideal for any flat roof installation where light and comfort are priorities.

Precision Triple-Glazed Construction

Each Rooflight Factory skylight is engineered with three expertly manufactured glass layers that deliver superior strength, safety, and insulation:

  • Top Glass Layer:  6 mm Planibel Clearlite / Thermally toughened glass BS EN 12150
  • Middle Glass Layer: 6 mm iplus Thermally toughened glass with Low-E coating EN 12150
  • Bottom Glass Layer: Stratobel Clearlite 44.2 / Laminated glass EN 14449

The triple-glazed design achieves an impressive U-value of 0.9 W/m²K and a G-value of 58%, combining high thermal efficiency with excellent light transmission. The Low-E coating reduces heat loss, while the 90% argon-filled air gaps and warm-edge spacers minimise condensation and improve overall performance. This clear-tint glass also features self-cleaning technology and UV protection, ensuring long-term clarity and reduced maintenance.

Safety and Compliance

Safety and quality are at the heart of every Rooflight Factory product. This skylight is fully compliant with British Standards and Building Regulations and comes with all required Safety Markings. It is CE marked, confirming it meets all EU safety and performance directives. Designed for a maximum installation pitch of 45 degrees, it guarantees both resilience and reliability for long-term use.

Installation Guidance

For best results and a watertight finish, Rooflight Factory recommends the following installation practices:

  • Dimension Note: The top pane features a black border, extending the external size by 200 mm in all directions.
  • Opening Preparation: Allow an additional 10 mm internally from upstand to upstand for proper fitting. For example, a 600 x 900 mm unit requires a 610 x 910 mm internal opening.
  • Upstand Construction: Build the upstand (timber framework) using 2×1 or 2×2 inch timbers to ensure robust support.
  • Foam Rope and Sealant: Apply foam rope on the internal support baton to distribute the weight evenly. Seal the perimeter using Dowsil 791 black silicone sealant for a watertight finish. Acrylic sealants must not be used as they are incompatible with this glazing system.

Customisation Options

Rooflight Factory offers a wide range of custom-sized frameless skylights and oversized frameless skylights to meet individual project requirements, ensuring a perfect fit and sleek integration into your roof design.
