ARC Hosts First Webinar on Tackling Damp & Mould at the Eaves Junction

ARC Hosts First Webinar on Tackling Damp & Mould at the Eaves Junction

04th September 2024

Catch up on our webinar

In case you missed it, we have just launched the first in a series of webinars focusing on the technical aspects of ARC products. Committed to driving innovation, we ensure that we don’t only make great products, but that we know them inside-out and have the technical knowledge and expertise in-house to provide expert support.

Designed to make technical information more accessible, the sessions will focus on the key site challenges facing ARC customers and how our innovative products can help you tackle them.

The first session was hosted by our very own Product Innovation Manager and insulation expert, Dr Alex Boote. With three patents and an engineering PhD already to his name, if there’s something he doesn’t know about our products, it isn’t worth knowing.

Correct Insulation Is Vital

Focusing on the pervasive issue of damp and mould, which makes national headlines on an almost weekly basis, Alex highlighted the importance of correct insulation in tackling damp and mould development, particularly at the notoriously challenging eaves junction.

The session began with Alex explaining why insulating homes is so crucial, particularly in the modern era where sustainable building practices and the cost of living are bringing greater emphasis to energy efficiency within the home.

Ventilation and Insulation

Things got technical as Alex explained the basics of U-values and why ventilation is another critical factor in reducing a property’s risk of developing mould and damp. A gap in the insulation at the eaves detail will result in a thermal bridge and a cold spot on the internal walls where moisture in the air can condense and mould will begin to grow. As a result, maintaining a ventilation path is crucial.

One of the biggest challenges is the huge variance we see in properties in UK housing stock. From pitched roofs to flat and varying rafter dimensions and spacings, correct insulation is not one size fits all. With regulations like PAS 2035, Awaab’s law and NHBC requirements bringing added pressure to get this right, having the right solutions has never been more important.

The Retrofit Eaves Insulator

Launched in 2024, the Retrofit Eaves Insulator is our answer to this problem. The only product of its kind on the market, the Retrofit Eaves Insulator has been developed specifically to address heat loss at the eaves junction, providing sufficient insulation, whilst maintaining a ventilation gap. Alex explained the need for the product and its role in tackling mould and damp in diverse UK housing. He also offered tips and tricks for simple installation and how our robust range of sizes ensures every home can be retrofitted effectively, protecting against damp and mould formation.

The session was well attended and invited some interesting questions from the audience, including whether the insulator is suitable for use with sarking. The answer from Alex was that yes it was, again proving the versatility of this fantastic innovation.

Thank you to all those who attended our damp & mould webinar, it was a great experience to have the opportunity to share knowledge.
