EcoGard Flat Rooflights and Flat Roof Skylights

The contemporary high performance roof light guaranteed not to leak



The new EcoGard range of roof lights for flat roofs are manufactured to the highest standards and competitively priced. Careful attention to detail and selection of high performance sealants that last, ensure we can confidently offer a 10 year guarantee against leaks when installed within our recommendations. However, building owners can be confident EcoGard will give many years good service with a design life of 25 years and virtually zero life-cycle costs.

Designed for easy fixing to builder’s curb, but why not save valuable time on site and order one of our flat pack timber curbs which incorporate the necessary 5° fall? These are available in standard sizes and can be sent next day so the roof opening can be prepared prior to delivery of the roof light.​

“When it came to a rooflight for my own studio, Lonsdale proved the obvious choice” - Sir Terry Farrell, Terry Farrell & Partners

FIXED - A range of fixed glass rooflights in various shapes and sizes are available, so don’t be limited to square or rectangular shapes! We can manufacture round, triangular or irregular shapes in any standard RAL colour. Similarly, if you have a requirement for a continuous rooflight made up of several glass roof panels, we can build rooflights up to 2500mm wide x infinite length.

OPENING - Opening rooflights are available for both access and ventilation including smoke ventilation to EN12101. A range of motors and gears are available for both electric, automatic or manual operation and there are few circumstances we have not yet encountered if you require a custom solution. Various Ecogard Access Rooflights or Opening Rooflights are available to suit flat roofs or pitched roofs upto 45 degrees. Please ask

WALK-ON - We work to the highest standard of safety and exceed building regulations as we build our walk-on rooflights without compromise. Non-slip patterns are also available.

MANSAFE - Non-fragile rooflights are available by using upgraded glass in accordance with CWCT TN92 non-fragility recommendations.
