Weather tightness of doors – what you should know
Weather performance – an introduction Unlike thermal performance, there is no minimum standard required under Building Regulations for weather performance and as a result the range of performance across various door systems and manufacturers varies greatly. When we talk about weather performance we are looking at the protection that doors offer from drafts (air permeability), rain (water tightness) and wind (wind load). Every set of door on the market should be tested, but with no minimum standards required it is the test figures themselves that offer the best indication of the quality and performance of the systems. How are doors and…
