Sleek Frameless Design
Thermalight frameless roof lanterns are designed to maximise natural light and create a stunning architectural feature for any flat roof. The ultra-slim, glass-to-glass joints use structural silicone bonding for a clean, modern look with no bulky framework in sight.
Built for Strength and Security
Every roof lantern is made using heat-soak tested, toughened safety glass for complete peace of mind. For new builds or projects needing enhanced protection, Secured by Design Part Q compliant options are available, fully tested to meet LPS 2081: Issue 1 standards.
Each double-glazed unit is fully enclosed within the aluminium perimeter frame to protect the glass edges and help rainwater drain away quickly – reducing cleaning and keeping maintenance to a minimum.
Premium Materials & Energy Efficiency
Made from thermally broken aluminium for excellent insulation, our lanterns are powder-coated Anthracite Grey (RAL 7016) externally and White (RAL 9910) internally as standard. Other RAL colours can be supplied on request.
