GRP profiled rooflights are available in hundreds of different profiles to match all current and most discontinued metal and asbestos cement roofing/cladding profiles. The sheets are laid to over- or under-lap roofing profiles to provide in-plane rooflights – typically in factory or warehouse roofs.
Profiled sheets fall into two broad categories:
- Sinusoidal profiled sheets – these have curved or ‘wavy’ profiles. Sinusoidal profile sheets are generally used in agricultural or utility buildings.
- Trapezoidal profiled sheets – these have angular profiles. Trapezoidal profile sheets are commonly used on industrial and commercial buildings.
GRP sheet is typically used for ‘in-plane’ rooflights that follow the line of the roof. However, out-of-plane GRP rooflight designs are also available.
