Using opal-coloured plastic roofing for a pergola offers a balanced combination of light transmission, heat reduction, and comfort, making it an increasingly popular polycarbonate roofing option for outdoor spaces.
Light Transmission:
Soft, diffused light: Opal allows a moderate level of natural light to pass through, usually around 50% light transmission depending on the specific material and thickness. This ensures the area under the pergola remains bright without being harsh.
Heat reduction:
- UV protection: High-quality opal roofing blocks up to 99% of harmful UV rays, helping to protect both people and furnishings from UV damage.
- Lower indoor heat gain: If the pergola is attached to a building, using opal roofing can help reduce heat transfer into adjacent indoor areas. Opal, being a lighter colour tends to naturally reflect heat making it a good choice for areas that get a lot of sun.
Comfort:
Cooler temperatures: The combination of light diffusion and heat reduction helps maintain a cool, shaded environment, ideal for relaxation or entertaining.
Privacy: Opal roofing offers semi-opacity, meaning it allows light in but limits visibility from above—offering a degree of privacy without enclosing the space too much.
