High-Performance Flat Roof Daylight Solutions by Coxdome

For decades, Coxdome has been a trusted brand name for roofers, builders, and homeowners across the UK seeking high-quality natural lighting solutions for flat roof applications. At LB Supplies, we supply the complete Coxdome range, offering robust, energy-efficient, and easy-to-install daylighting products designed to transform dark interiors into light-filled spaces.

Why Choose Coxdome Rooflights and Domes?

Coxdome roof windows and skylights meet the highest structural and thermal standards, making them an ideal choice for new builds and refurbishment projects. Key advantages include:

• Maximum Natural Light: Specially engineered profiles maximise the clear glazing area to draw abundant natural daylight deep into property interiors.
• Exceptional Thermal & Acoustic Insulation: Options like the Coxdome Lumiglaze feature double/triple glazing with thermal breaks and high noise reduction properties to keep heating bills low and external noise out.
• Durable & Weatherproof Construction: Made from high-impact UV-inhibited polycarbonate or toughened safety glass, paired with high-grade extruded aluminium or PVC kerbs.
• Flexible Ventilation Options: Available in fixed designs for pure illumination, or manual and electric opening units for controlled background airflow and smoke ventilation compliance.

Frequently Asked Questions

What is the difference between a clear and a diffused Coxdome dome?

A clear Coxdome provides high clarity and direct sunlight penetration, making it ideal for living areas and open workspaces. A diffused (frosted) Coxdome scatters light evenly across the room to reduce glare and eliminate harsh shadows while offering privacy for spaces like bathrooms or corridors.

Can Coxdome rooflights be installed on existing timber kerbs?

Yes. Coxdome glazing units can be ordered as glazing-only (top unit) to fit onto existing builder’s timber upstands, or supplied complete with a matching Coxdome insulated PVC upstand for standard flat roof installations.

What opening mechanism options are available for Coxdome rooflights?

• Fixed: Non-opening unit, optimal for daylighting with zero maintenance.
• Manual Opening: Operated via a hand pole and spindle mechanism for easy airflow adjustment.
• Electric Opening: Powered by a 230V mains actuator (or 24V for specialist smoke ventilation), controllable via wall switches or remote controls.
