Soffits for new builds and refurbishments
Soffit boards are the boards that run horizontally from the back edge of the bottom of the fascia board to the top of the wall, closing off the roof space at the eaves.
Our soffits are manufactured from PVC and can be used in new builds and refurbishments in order to add an eyecatching finish to your property. There are three main style variations of soffit:
Furthermore, each style soffit comes in varying lengths and five main colours; white, black ash, golden oak, rosewood, and anthracite grey (except vented soffits).
Features and Benefits of UPVC Soffits
We sell FloPlast UPVC soffits which means that our product is supplied with the high quality and product reliability to be expected from an award-winning manufacturer. In addition, our UPVC Soffit conforms to a number of British Standards and comes complete with industry-leading guarantees.
The UPVC soffit boards stocked by PVC Cladding offer a blemish-free, maintenance-free solution as they are impermeable to weather and hence will not deteriorate or rot.
Roofline ventilation options are numerous with UPVC Soffit Boards ranging from the installation of circular disc soffit vents and soffit vent strips to vented Soffit Boards.
As with timber UPVC soffit boards can be drilled, screwed, pinned, and cut using suitable tools; however, unlike timber, they do not ignite easily so are more fire retardant.
Soffits are non-load bearing, so this is something to be mindful of if there are plans to attach decorative features, such as hanging baskets. This can cause tension in the soffit that cannot be withstood, resulting in bending, bowing or even to become unfastened.
Where does the Soffit Board fit?
For those that are a little unsure about which sections go where on the eaves construction, the following video gives a brief introduction of the key terms used in the trade.
UPVC Soffit Board Styles
PVC Cladding stock a variety of different styles of UPVC soffit depending upon the desired finish and application.
- In a refurbishment project involving the replacement of old timber, plywood or masterboard type soffits, our plain soffit boards are the ideal solution. These multi-purpose soffit boards are 10mm thick and come in a range of widths from 100mm (4") to 404mm (16").
- If the board which is being replaced has ventilation strips cut into it then our vented soffit boards would be the ideal solution to ensure ventilation to the roof space. These vented soffit boards are 10mm thick and come in a range of widths from 100mm (4") to 404mm (16"). In the case of a new build project, whether this be a new section of roof or a complete build our range of Vented Soffit will provide the ventilation to the roof space required by Building Regulations, and depending upon how the architect has decided to vent the roof space will often provide the simplest and most easy to install solution.
- In circumstances where the dimension of the soffit is particularly wide for example in a porch area, or where a "tongue and groove style" effect is desired our range of hollow soffit is the ideal solution. As well as producing an attractive "cladding style" effect the Hollow Soffit stocked by PVC Cladding is easy to install as it is light in weight terms.
All the styles of UPVC soffit stocked by PVC Cladding come in 5m lengths as standard.
Plastic Soffit Colour Finishes
PVC Cladding stock a range of colours of plastic soffit boards in white, anthracite grey, black ash, golden oak and rosewood.
Guarantee and Fire Rating of UPVC Soffit
The UPVC Soffit Boards stocked by PVC Cladding carry a product performance and discolouration guarantee of 10 years.
Is PVC Soffit Safe?
Our FloPlast soffit boards carry a Class 2Y surface spread of flame rating in accordance to BS 476-7: 1997, while our hollow soffit boards have achieved a Class 1Y rating. This means that although the spread-of-flame across the surface of PVC is limited, the material does tend to char and may fall away when exposed to fire.
However, it is unlikely that the roof trim system will significantly affect the overall fire performance on any roof on which it is installed. Where it is normal practice to carry the eaves over, between dwellings, the box must be fire stopped at compartment walls with a proprietary fire stop material.
UPVC Soffit Installation Guidance
UPVC plain and vented soffit boards should be fixed using two 40mm Polytop pins at intervals of no more than 600mm for white boards and 400mm for woodgrain boards. In the case of hollow soffit boards, these should be fixed with stainless steel cladding pins which are hidden by the "tongue and groove style" effect.
Full soffit board installation instructions can be found in our Guides and Tips section.
