The Outlook range is a high quality product in a limited range of sizes meeting the basic needs of Roofers, Builders & Developers without sacrificing material specification. The Outlook flat roof dome features a double or triple skin of UV enhanced polycarbonate glazing in a dome which is long lasting and highly durable. There is also an option for either clear or obscure glazing. A 150mm high uPVC upstand is included within the package and is suitable for all traditional roof finishes with no internal decoration required. A 300mm high uPVC kerb is available, upon request, for an extra charge. As well as the standard unvented/fixed option we can offer a pole operated hinged wormgear (as shown) or an electrical hinged linear motor which can be provided with the 150mm high kerb. These work on the principle of a hinged lifting frame (with the polycarbonate dome attached) rising away from the kerb on one side. This opening will maximise at approximately 30 degrees to the horizontal. The electrical linear motor will need to be wired to the power source by a qualified technician and will require an extra on/off switch to operate too.
