UPVC Roofline Installation - PDF
Take a look at our leaflet on installation tips for UPVC roofline components, in refurbishment and new build replacement projects.
PVC Cladding sell Vented Soffit which complies with UK Building Regulations by providing the equivalent ventilation of continuous a 10mm wide air gap, this is the requirement for roofs with a 30° pitch and over. These UPVC Soffit boards bridge the gap between the wall and the rear facing side of the fascia board effectively closing it off whilst also allowing air access to the loft space to prevent condensation build up. We can also supply double-vented soffits for very low pitched or flat roofs - please contact us for further details (please note we are currently experiencing production problems for double vented soffits and therefore the ETA for special orders will be longer than usual).
Even where vapour permeable underlays have been used instead of bitumen based roof felts it is still likely that the amount of moisture carried into the roof space will exceed that which the underlay can deal with at certain times in the year, this could result in damp insulation so our Vented Soffit is an excellent solution for the eaves venting.
Soffit is installed horizontally at the back of the fascia - the video below explains this in visual terms.
Watch our video where we explain the different types of fixings used for PVC Fascia and Soffit Systems.
Watch our video to see how to install corners and joint trims on PVC Fascia Boards, allowing the system to expand and contract.
