Showers...storms...drizzle...We hate to break it to you,but the average rainfall in the UK is between 700mm a year in East Anglia and 3,000 a year in the Scottish Highlands.
That's a lot of potential for leaks,puddles or even worse.
The composite doors are tested by the BSI by spraying six litres of water every minute directly at the door in their test chamber.That's a serious amount of rain.
So even when it's raining cats and dogs out there,your composite door will keep you snug and dry.
