  • Can I install your Rooflights onto any roofing substrate?

    Yes, this is no problem. However you must make sure the correct sealant is applied depending on the substrate.

  • What’s the difference between glass to glass joins and the usual bars you find in standard Roof Lanterns?

    Replacing bars with structural glass to glass joins means we can achieve better U-values, keep the Lantern more thermally efficient yet still maximise light with much thinner hips and ridge. Overall, accomplishing a more aesthetically pleasing and neater product by design.
