How is the aluminium frame constructed?

Our aluminium frames are designed to work perfectly with our laminated insulating glazing units. They are crafted from highly durable and strong 5 mm aluminium, selected for its high corrosion resistance, joint strength and malleability. All our frames are hand-welded on the inside of the corner sections to ensure a smooth surface and a completely tight connection. They are treated with a polyester powder coating to ensure a hard and durable outside finish. The standard RAL powder coating on our frames is a RAL 9005 Jet Black.

How is the upstand constructed?

Our rooflights come with a wooden upstand that uses rock wool insulation. The natural wood allows for an easy and safe installation and is a perfect match to the remaining rooflight construction. The upstand comes with a superior pre-fitted gasket system, ensuring a 100% tight and secure connection between the frame and upstand construction. The internal surface and the top of the upstand is treated with a membrane of waterbased white coating (RAL 9010) on the waterproof plywood. The external surface of the upstand consists of untreated waterproof plywood , which is great for applying roofing felt or other flat roof or roof terrace materials. The upstand comes with a pre-installed vapour barrier, which ensures a safe and easy connection to the roof itself. Our upstands come in 150, 300, 450 mm, depending on project requirements and architectural specifications.

Can the upstand be custom-sized?

If you have a special project where you need an upstand with bespoke measurements, please reach out to our daylight experts to discuss it further.

Does the Round one come with an upstand?

The Round One is the only product in Vario's product portfolio, which does not come with an upstand. However, we don't leave you entirely on your own! Vario will supply a top-plate (RAL 9010) with a pre-installed gasket system for optimal air tightness, ensuring a 100% tight and secure connection between the frame and upstand construction. It will be necessary for the upstand for The Round One to be constructed by others. The upstand can be built in various ways to fit the architectural requirements of the building, but if you are interested in the Vario way of building them so you know what to specify, we use a wooden upstand of min 150 mm that is insulated with rock wool.
