Guidelines for Installation and Best Practices

Measurement of Internal Dimensions and Structural Opening:

Please be aware that the quoted size is the internal size of the unit which when measured should be taken from upstand to upstand plus an addition of 10 mm in width and length to allow to skylight to fit freely in the structural opening (e.g. a 1000 x 2000 mm skylight would require a structural opening of 1010 x 2010 mm from upstand to upstand)

Upstand Framework Construction and Installation Tips:

For the construction of the upstand that the skylights overhang sits on we would suggest using 4 x 2 inch timbers and 2 x 1 inch or 2 x 2 inch timber batten running on the inside where the bottom pane of glass rests.

We recommend the upstand to have a minimum of 6 degree pitch (preferably on the short side) to avoid water pooling in the middle of the unit which would mean roughly 10 cm for every 1 linear meter of skylight. For instance, a 1000 x 2000 mm unit would require one end of the upstand to be 10 cm higher than the other if skylight pitched on the short side and 20 cm higher if pitched on the long side.

Make sure a foam rope is placed on top running all along the timber batten eliminating any unevenness and aiding in the distribution of the weight of the skylight evenly across the surface.

Apply black weatherproof sealant generously along the surface of the upstand where the overhang sits to fully seal the unit and guarantee protection from the elements.

Please make sure you only use silicon or polyurethane sealants.

Do not use any acrylic sealants as these could react chemically with the units finish material and could subsequently compromise the seal of the unit.
