Flat Skylights Installation

A period property in Stockwell required a solution to bring natural light into a dark rear extension that had been used as a kitchen and dining area. The existing flat roof offered an opportunity to introduce daylight, but the space suffered from a dark, enclosed atmosphere that made it feel uninviting. The goal was to install flat skylights to flood the area with natural light, reduce reliance on artificial lighting, and create a brighter, more pleasant living environment.

Our Solution

We supplied and installed high-performance flat glass skylights designed for the flat roof extension. The solution included:

• Thermally broken aluminium frames to prevent condensation and heat loss
• Double-glazed units with low-E coating and argon gas fill for energy efficiency
• Walk-on rated glass (up to 150kg per square metre) for safe roof access during maintenance
• Anti-slip coating on the external glass surface
• Fixed glazed panels with optional electric opening mechanism for ventilation
• Skylights powder-coated in white to match the interior ceiling
• Tapered insulated upstands to ensure proper water run-off

Installation Process

• Conducted site survey and measured the flat roof opening dimensions
• Coordinated with the homeowners to confirm placement and access
• Cut the roof opening and installed timber upstands with proper insulation
• Applied waterproof membrane flashing around the upstand perimeter
• Lifted the flat skylight frames into position on the upstands
• Secured the frames using mechanical fixings through the upstand structure
• Installed double-glazed sealed units into each frame
• Applied external lead or aluminium flashing for a weatherproof seal
• Tested the electric opening mechanism (where specified) for smooth operation
• Completed internal plastering and decoration around the skylight reveals
• Cleaned all glass thoroughly internally and externally
