PPS 15 Planning and Flood Risk (Revised)·Page 78
Sealed Doors and Windows
Entrances and openings should use raised thresholds and water-resistant materials such as PVC frames and double-glazed windows to prevent water ingress during flooding.
Entrances and openings can be designed with raised thresholds. Water resistant PVC type material, which can provide better seals can replace traditional wooden frames, which can become warped. Shatterproof / double glazed windows should be considered as these are more liable to remain intact when exposed to a depth of flood water or floating debris.
