The purpose of guttering is to protect your property from the wet and to lead water away from the house block in an effective way. Each millimetre of rain corresponds to one litre per square metre of roof surface. Therefore, 20 mm of rain during the day on a roof surface of 150 m2 gives 3 m³ of water to be led away from the house. A heavy shower of 50 mm on the same roof gives 7.5 m³ to be led away in one hour. Our guttering system is designed to safely and effectively lead away rainwater to avoid water damage to the foundations and basement walls.
