Thermadome Kerb Options

Why choose Thermadome upstands?

Thermadome upstands are designed for use with Thermadome rooflights and as a result provide the best thermal interface when combined as a unit. This helps to make the roof more thermally efficient and cuts down on energy bills.

Thermadome upstands have a multi-chambered construction which makes them tough and adds to their thermal efficiency. The upstands are suitable for most roof finishes, come in a range of heights from 150mm – 350mm, and are compatible with various ventilation and access hatch options.

Thermadome Rooflight Kerb Options

Thermadome upstands provide outstanding value for money, are easy to install, and enhance the overall look of the rooflight. Plus the upstands are pre-finished in white on the inside so they don’t need additional painting.

Upstands are available as both splayed and vertical units. The splayed units are best for spreading the light through a room however the vertical units are more suitable where the dimensions of the roof aperture need to be preserved.

Thermadome upstands come with high security fixings that make it difficult for intruders to get in. However for those who require an even higher level of security an optional security frame is available which fully encloses the fixings within an aluminium framework.
