What is the cost of getting your property maintenance company to redo failed foam seals? It is better to pay a little more for a quality solution and do the job properly and know that you wont have to return over and over again to fix up failed foam seals. Why are EVS Draught seals so good? Well, firstly the are rigid seals that can be fitted to cover gaps that can taper from 1mm to 10mm. They are made of materials that are durable and have been tested for over 20 years with little deterioration. Provided they are fitted correctly they should last at least 20 years. 

Fanlight windows are used for providing ventilation however that are can be difficult to seal closed due to their hardware or being poorly fitted. They are also higher and can lose a lot more heat and waste energy. Follow our step by step instructions to provide your Fanlight windows with the best draught protection for ongoing peace of mind.
