'Structural Silicone Glazed Rooflights'
Aurora Walk On Rooflights
Our walk on rooflight is designed to be flush with surrounding flooring, typically on roof terraces with decking. As with all our Aurora rooflights a builders kerb is required for this product. The rooflight should be fitted first, with the surrounding flooring completed afterwards enabling an overall flush finish to be achieved. With a walk on product it is essential that the correct loading standards are considered, reference should be made to Eurocodes BS EN 1991.
Our walk on rooflights are suitable for residential applications and have been designed to meet with the imposed load requirements of BS EN 1991 Subcategories A1, A2, A3 and A5. This means that they are acapable of withstanding a uniformed distributed load (UDL) of 2.5kN/m² and a concentrated load of 2.0kN. Note, for new projects started after 1st October 2013, walk on rooflights stating only compliance to the lower loads defined by BS6399 (1.5kN/m² UDL and 1.4kN concentrated load) should be avoided.
Following extensive structural glass calculations our smallest rooflights incorporate an external pane of toughened laminated glass which is 25.5mm thick. As you might expect, as the rooflight size becomes larger so does the thickness of the glass that you would be walking on, so our longer rooflights feature an external pane of toughened laminated glass which is 31.5-33.5 mm thick (dependent on ultimate glass specification).
Our rooflights achieve outstanding thermal performance. True U-value and Ud-value available upon request.
The extruded aluminium perimeter frame is powder coated RAL 9005 black matt as standard. Other RAL colour options are available upon request.
Avant Garde or Sandblasted anti-slip external glass treatments to BS7976-2 are available upon request.
Structural silicone glazing is a method utilising a silicone adhesive to attach glass to metal. Wind loads and other loads such as snow and impact loads, are transferred from the glass through the structural silicone adhesive to the perimeter frame of the rooflight and from there onto the structure of the building. It is absolutely imperative for the long term performance of any rooflight constructed in this manner, that the silicone bond maintains its adhesive and cohesive integrity, which will be tested to extremes by wind load and thermal stresses throughout its service life.
Our contemporary product range has been created using the very latest structural silicone glazing techniques, standards of best practice in quality control. All Aurora structurally glazed rooflights are manufactured under strictly controlled conditions.
Our double glazed units incorporate a secondary silicone unit seal to prevent the delamination of the double glazed unit by UV light and are fully enclosed within the rooflights perimeter frame to minimise the risk of glass breakage. The silicone used in the edge of the double glazed unit has been thoroughly tested to ensure its compatibility with all other silicones and materials used within the construction of our rooflights.
The Low E, or low-emissivity coating to the glass is a transparent, microscopically thin metallic coating that works in two ways to economise heating energy. The dual action coating reflects the majority of heat back into the room thereby reducing the heat loss through the rooflight, and allows heat and light from the sun (known as passive solar heat gain) to pass through. These properties thus reduce the demand for energy to heat your home.
Bespoke sizes are available upon request.
Lead times vary from 5 working days to 4 weeks dependant on the size requested.
