Combination Flashing Kits

Flashing is an incredibly important part of roof window installation, ensuring your roof stays water resistant and potentially providing additional insulation.

If you are installing multiple Velux roof windows side by side or one above the other, one of our combination flashing kits is a must in order for them to be seamlessly fitted together. Here at Building Supplies Online, we offer Velux flashing kits for coupled, duo, triple and quatro combination windows; browse our selection below to find the right one for you.

Choosing your combination flashing kits

The Velux flashing you need will depend on many different factors and we offer a wide selection of high quality Velux flashing kits to accommodate this. We have over 20 sizes of Velux flashing available, depending on the size of your windows, as well as multiple options for the size of gap you want between them. The type of flashing you need will also depend on the type of tile you have on your roof, with slate, concrete and plain tile options all available for you to choose from. Sort our selection by price to find the cheapest options available for your specifications, or have a look at our best sellers to find the combination flashing kits that our other customers have loved.

Coupled combination vs duo combination flashing

Both coupled and duo combination flashing kits provide flashing for sets of two Velux roof windows, but they are not the same. Whilst coupled combination flashing is for two windows side by side, duo combination flashing is for 2 windows on top of each other. Make sure you know which one you need before ordering one of our kits. Roof windows are a great solution for letting light into any extension or existing room.
