Technical Specifications

Supplied with Bespoke Upstand

To comply with building and safety regulations, all skylights must be fitted with an upstand to keep the glazing unit raised above the surface of the roof.

Our O-lite round rooflight is provided with a timber upstand at no extra cost. The structure conforms to the minimum, low-level height for a flush-glazed appearance.

We recommend that our round rooflights are installed with a minimum of five degrees pitch.

What is a U-value?

The U-value of a product measures how effective its insulation properties are. The lower the U-value, the better the insulation. As a guide, a standard double-glazed window typically has a U-value of 2.8 W/m². Our triple-glazed units have a U-value of 0.6 W/m².

What is a thermal break?

A thermal break is a material with low thermal conductivity placed between conductive materials to reduce or prevent the flow of thermal energy.

In our products, these thermal breaks include resin, silicone and styrofoam, which separate the conductive aluminium components to provide superb thermal insulation

Will it be noisy if it rains?

Sound insulation is important when choosing a skylight product. There are four main factors that can limit rain noise:

  1. The number of panes of glass — noise levels are reduced with each additional pane;
  2. The distance between the panes — the greater this distance, the better your sound insulation will be;
  3. The thickness of each pane of glass — thicker panes absorb more noise; and
  4. How well your skylight is sealed against the roof.

Many Roof Maker products are triple-glazed as standard with 6mm toughened safety glass and a generous 16mm gap between the panes. Further insulation in the skylight’s structure keeps rain noise to a minimum.

What pitch should my flat-roof skylight be?

We recommend that our flat skylights are installed with a minimum five-degree pitch. This angle is enough to ensure that rain water will run off the surface of the skylight rather than pooling.

If your flat roof does not already have a five-degree pitch, the angle will need to be achieved by creating a small timber frame.

Read our helpful article on the correct pitch for flat rooflights.

What sizes should I measure?

The measurement we work from is the INTERNAL hole size — so measure the size of the hole.

If you want to leave the black aluminium frame of the skylight showing, then include finish plasterboard. If not, then give us the size of the hole before plastering.

Our skylights are designed using a 70mm wide aluminium kerb detail profile. This can sit on a minimum 70mm wide x 25mm deep timber frame.

What is the largest size skylight you could make for me?

The largest size we currently offer our O-lite round rooflight in is 1,500mm

Can I see your products in person?

Yes , our Leicester showroom welcomes both trade and residential customers. Here you can see our range of products and our manufacturing facilities. Our experienced sales team will be on hand to answer any questions and demonstrate the product features, such as the manual or electric opening roof vents, which provide natural ventilation.

Can I collect from you?
