Façade membranes will never receive the gold medal for being the most glamorous products ever to grace a construction site.  That prize would probably go to some of the incredible cladding and glass structures that ultimately give buildings their individual style and character. 

But beyond their bland appearance, façade membranes play a critical part in ensuring a building is watertight, airtight and above all, safe.  

So it’s vital that all façade sealing membranes are tested to the correct stringent standards so that regulatory compliance is achieved.  But crucially, it also needs to be established beyond any doubt that they will continue to perform the primary function for which they are designed, ie. to form a robust, weathertight and airtight seal. 

This is why the well-proven 0500FR Class B Interface Sealing Membrane has become the industry standard for sealing windows and façade interfaces, and has been trusted by architects, main contractors and installers for over 6 years.  

It is the only Window and Interface Sealing Membrane system that offers:  

  • full compliance with the regulatory requirements for minimum Class B 
  • the highest level of water penetration resistance 
  • a proven track record for over 6 years, on hundreds of projects across the UK and Europe 
  • a Paste Adhesive that is truly Class B 

0500FR was first used on a project in early 2018, following over 2 years of research and development, and has undergone 22 different tests by third-party testing houses.  Since it was launched, over 10 million metres of 0500FR have been specified and installed on projects across the UK and Europe.  Testament indeed to its high performance and long-term durability.
