Metal & Glass Limited offers a range of glazing solutions for flat roof applications. Our flat skylight system boasts large thermal breaks to provide industry leading, truly tested, U-values. Providing a minimalist aluminium structure is essential to our flat skylight design, whilst also offering a very versatile frame construction that allows for double and triple glazing to be utilised yet remain flush with the frame. Let our flat skylight design provide a frameless glazing solution for your flat roof.
Our flat skylight system is produced using thermally broken aluminium which incorporates two 27mm polyamide inserts. These polyamide inserts reduce heat transfer through the aluminium and plays a big part in stopping both condensation and heat loss. To ensure that you are comparing like for like flat rooflight quotations, we would also advise that you check as there are some skylights and rooflight systems out there are just made of a single piece of aluminium and it will be highly unlikely that cheaper systems will have genuine thermal testing results so ultimately providing a far less thermally efficient product. In addition our flat rooflights use a triple seal gasket system to ensure industry leading weather performance.
Another benefit offered by the Metal & Glass flat skylight is a 48mm frame overhang which provides an improved weather tight seal. Furthermore, our flat rooflight has no external fixings to significantly improve the weather proofing properties. To improve the installation process our frameless flat skylight glazing is supplied with metal fixings straps which are screwed into the internal timber upstand and then covered over with plasterboard, ensuring a perfect frameless look.
The Metal & Glass flat skylight should be fitted to a site built kerb upstand section which needs to provide a minimum pitch of 5 degrees and a maximum pitch of 40 degrees. The minimum pitch reduces the risk of water pooling on the flat rooflight glazing.
We offer a range of standard sized flat skylights but can also produce bespoke sizes to suit your individual requirements. The majority of our flat rooflight products are supplied with one unit, to maximise the amount of natural daylight. The maximum size of our flat rooflights is dependent on the weight of the finished product and our ability to safely lift in production and manage the delivery. The bigger your flat skylight, the thicker the glass needs to be and by increasing the unit thickness you are also increasing the overall weight of the skylight. Our expert team will be able to advise the most suitable glazing specification for your flat rooflight, taking into account safety, wind & snow loading and current regulations. With particularly large rooflights it will be necessary to divide the glass units using aluminium glazing bars. In this situation, your flat rooflight will be supplied in kit form ready for your contractor to assemble on site. We will supply all the necessary glazing tapes and silicones to achieve the perfect finish to your flat rooflight. Dividing large flat rooflights with glazing bars also makes transportation and installation easier and removes the need for costly lifting equipment. You should always consider how you will unload and install your flat rooflight and if access and weight are an issue, we would recommend using the glazing bars and onsite assembly.
If your flat rooflight is situated at a height greater than 5mts above the internal floor level then you must have an internal pane of laminated glass. Laminated glass is constructed of two plies of glass which are bonded together with interlayers to form a permanent bond. The interlayers work to support and hold the glass to create a strong, uniformed layer even when broken. Laminated glass comes in varying thicknesses and can be created using different glass combinations or coatings to provide different qualities. As laminated glass doesn’t shatter when broken, there is a reduced risk of someone being cut or injured by shards of glass.
Metal & Glass Limited flat rooflights are finished in a tough and long lasting polyester powder coat. Our standard flat rooflights are produced in either RAL7016 anthracite grey or RAL9005 black. Unless otherwise requested the internal and external frame colour is the same however, we can offer dual colours if required. We can produce bespoke flat skylights in any RAL colour. This incurs a surcharge but please speak to our team for delivery times and pricing details.
Most flat roof glazing will be manufactured in a fixed, non-opening design. Not only are fixed flat skylights more cost effective but it also allows you to have bigger sizes. Where an opening rooflight is required we can provide a range of options, including manual, electric or an access rooflight version which opens to 90 degrees. If your flat skylight has an external manufacturing size which is 1200mm x 1200mm or smaller then it will be possible to operate it using our manual screw jack winder. Should your flat rooflight be larger than 1200mm x 1200mm then we can provide an electric actuation option. This is a small box which sits within the cill profile of the skylight and pushes open the casement with a chain. Opening distances can vary but the most common chain length is 400mm. The number of drives required depends on the casement size and weight. All Metal & Glass electrically actuated flat rooflights are supplied with a wireless remote control and rain sensor, which will automatically close you skylight when it is raining. Our electric actuators can be fitted to flat skylights which have a maximum manufacturing size of 2000mm x 2000mm or 1000mm x 3000mm.
