FAQs

What does “Thermally Broken” mean?

“Thermally broken” describes a type of reinforced building material that enhances insulation in a building. This material could be aluminium, steel, or bronze. Combined with the rest of the components of the SpanGard rooflight, you will notice that your building uses the artificial heat you provide it far more efficiently thanks to the thermally broken materials.

Do SpanGard Roof Lanterns make a room cold in winter?

No. SpanGard roof lanterns do not make a room colder. If your room isn’t artificially heated, the rooflight will not introduce heat to it, but it will prevent heat from escaping. You will notice that your rooms feel warmer for far longer with a SpanGard roof lantern, as the insulating properties of the rooflight will prevent the heat from egressing your room. 

Are SpanGard Roof Lanterns liable to leak?

SpanGard roof lanterns are not liable to leak if installed correctly. The silicone seals which surround the roof lantern are water-tight and prevent moisture from getting into your building. But if the silicone seals aren’t laid properly, water will get through and cause problems around your rooflight and in your room. 

How much does a SpanGard Roof Lantern cost?

Due to the sheer number of variables that go into our SpanGard roof lanterns, we cannot publish an accurate price estimate on our website. We offer many shapes and sizes that are all custom-made to order, so if you need a rough estimate, please don’t hesitate to contact us! We’ll send you a personalised quote!
