Our range of Decorative PVC-U conservatorieS utilize the technical benefits of our drained and gasketed PVC-U window and door sections, and the conservatory roofs have been designed on the same principles. The roof sections have been designed to allow for thermal expansion and contraction, and incorporate an external drainage system to prevent any possibility of water ingress. All the roof rafter sizes are calculated to ensure that our conservatories perform to the requirements of CP3 Chapter V pt.2 with reference to wind and snow loading for any location in the U.K. specified to us.The roof rafters comprise an aluminium “T” section cloaked in PVC-U capping. There is one standard rafter size covering all glazing options - polycarbonate and glass. Variable thickness aluminium “T” sections are used to accommodate imposed loads and design spans. Correctly designed rafter sections enable: -

a) protection of the unit’s perimeter seal from ultra-violet light,
b) support of the unit on the horizontal plane thus avoiding stressing of the unit and the perimeter seals,
c) thermal expansion of the glass unit independent from the rafter

Elevation Modules are linked to each other with 10mm alumiunium reinforced PVC-U “joiners”. The standard module width without a mullion does not exceed 1200mm. 90 degree angled modules are linked with an aluminium reinforced 59mm PVC-U corner post, and non-90 degree angled modules are linked with an aluminium reinforced 50mm PVC-U pole. The Heads of all elevation modules are reinforced with 1mm galvanised steel to provide a fixing point for the roof eaves beam.
Roofs are “low maintenance” incorporating PVC-U finials, crestings and glazing beads. The aluminium “T” section structural roof rafters are sleeved in PVC-U

Roof systems can be mixed and matched with any of our window systems thus enabling you to create a conservatory which is unique and blends harmoniously with your house and surrounds. Similarly the PVC-U elevations enjoy the benefits of low maintenance.
