Why Choose Velux Flat Roof Domes?

When it comes to bringing natural light into flat-roof extensions, offices, or hallways, standard pitched windows aren’t an option. That is where high-quality Velux roof domes come in. Designed to deliver maximum daylight while offering exceptional durability, these units are the industry gold standard for modern flat roof renovations.

Every dome features a double-glazed inner unit paired with a protective outer polycarbonate cover. This unique dual-layer construction provides outstanding insulation, keeps your home secure, and significantly dampens the sound of heavy rain and hail.

Key Features of the Range

  • Fixed vs Opening Models: Choose fixed domes for simple, cost-effective light, or opt for electrically operated Velux Integra® domes to introduce fresh air at the touch of a button.
  • Glazing Options: Available with either clear polycarbonate covers for a direct view of the sky or opaque (frosted) covers for maximum daylight with complete privacy.
  • High-Security Design: Certified to European Security Standards (EN 1627-30), these domes feature sturdy steel-reinforced frames and tamper-proof security fixings.
  • Superior Thermal Efficiency: Excellent U-values help keep your space warm in winter and cool in summer, reducing your energy bills.
