Interactive online training from our Patron Member, Ecological Building Systems. Airtightness is critical when creating a low energy building. The benefits are significant and numerous, including structural durability and longevity, reduced energy consumption, improved levels of comfort and a healthy environment for occupants. Since we spend around 90% of our time indoors and most building failures are caused by moisture related issues, the need for active moisture management, lifetime building durability and a healthy living environment become more crucial than ever. This is covered in detail in this CPD.
