Vented Soffit Boards - 10mm
A pre-vented soffit incorporating air slots that provide ventilation to equivalent to a 10mm clear air gap, which conforms to current UK building regulations for new pitched roofs of 30 degree pitch and above.
SOFFIT BOARD PURPOSE
Soffit boards are used to close the gap at the underside of the rafters between the back edge of the fascia board and the external brickwork.
VENTED SOFFITS ON LOW-PITCHED ROOFS
For flat or low pitched roofs a double vented board is required for new build projects. Please contact us if your require further details and prices of double vented boards (please note we are currently experiencing production problems for double vented soffits and therefore the ETA for special orders will be longer than usual).
INSTALLING VENTED SOFFITS
Soffit boards should be fixed using 2 x 40mm Polytop pins spaced no further than 600mm apart (400mm for woodgrain boards). The range is available in white, rosewood, golden oak and black ash. For further information on the installation of fascia and soffit boards please visit our Guides & Tips section.
VENTED SOFFIT FIRE RATING & GUARANTEE
Our Soffit Boards are manufactured by FloPlast and are guaranteed for 10 years.
Is PVC Soffit Safe?
Our FloPlast fascia 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 box over, between dwellings, it is important that the box is firestopped at compartment walls with a proprietary fire stop material.
