Brett Martin Flat Skylights

PDF Installation guide can be found on the downloads tab

The size you select to order should match the final dimensions of your external upstand. For example, an external upstand measuring 1000mm x 1000mm would require a purchase measuring 1000mm x 1000mm.

The width of your upstand should measure 75mm.

There is a 20mm margin already built into our roof light design dimensions. This means that if your external measurements were 1020mm x 1020mm, it would still be suitable for a 1000mm x 1000mm fit.

Margin:

Fixed Flat Glass Rooflight = rooflight size (External Upstand) +20/-0mm

Self-clean glass is only fully effective when used with pitches of 10 degrees or greater. Please get in touch if you would like to include this option.

To fit this flat roof skylight a minimum pitch of 2 degrees is needed. For some larger sizes of Brett Martin Flat Glass a minimum of 4 degree pitch is required. The maximum pitch should be 15 degrees.

Additional options:

The following options may be selected for the glass on the non-opening flat roof windows:

• Solar control: An advanced coating is applied to the class which minimises the heat which penetrates the building
• Easy clean/self-clean: Coated to decrease the frequency and time required to clean the class
• Satin: Allows light to permeate but provides an extra degree of privacy
• Grey tint: the glass is tinted grey

Stippolyte: an opaque glazing which offers heightened privacy. Typically used in rooms or spaces which are overlooked from neighbouring buildings or from the exterior. The textured glass finish on Stippolyte will alter the light distribution.
