Sheerframe flood doors have been independently accredited and Kitemarked to meet the specifications of PAS 1188-1 (Flood Protection Products Part 1: Building Aperture Products) for single and double doors.
At the respected test centre at HR Wallingford, inward opening Sheerframe PVC-U doors recorded “no leakage” at 0.6 metre external submersion under static test over 48 hours.
The doors also remained watertight under dynamic tests simulating waves and rapidly moving water. French doors are also approved with just 0.001 litres of ingress after 48 hours, which compares most favourably to the standard test pass leak rate of up to 1000 ml/m/hour.
Sheerframe flood doors not only hold water out but, unlike the alternative of flood boards, they function easily and look like normal doors. In addition, they are fitted with specialist hardware to provide near impregnable watertightness and achieve PAS 24 levels of security. When locked, the Sheerframe flood doors are fully primed to prevent water ingress and virtually airtight as well as watertight. The doors can be internally bead glazed to achieve exceptional U-values down to 0.9 W/m2K when fitted with 44mm deep triple glazing.
“There’s a real market demand for flood doors” comments David Strang, Group Key Account Director at Sheerframe Ltd. “It is said that UK properties are more at risk of being flooded than being burgled and over 5 million properties are considered at risk according to the insurance industry. In the last 10 years there has been growing evidence that global warming has affected the nature of rainfall in the UK, with more intense rainstorms resulting in the worst floods in recorded history. Following the 2007 floods the Pitt report estimated flood damage cost in the UK as worse than anywhere in the world that year, with insurance industry costs of over £3 billion. Since then severe flooding has occurred in many parts of the UK with 2013 causing substantial damage, especially in the south of England.”
