Natural fibre wool insulation is key to controlling your homes energy use and humidity level. All insulation looks to be the same until you scratch the surface. Don’t be fooled by R-value statements and low-price points. Chemical infused Glass fibre insulation, Expanded Polystyrene (EPS) in panel form or spray form are the ‘’go to’’ insulation products but their stated insulation R-value is immediately impacted by moisture when installed in your home. Terra Lana wool fibre is EXOTHERMIC meaning it can absorb and release moisture from the air without impacting R-value. Maintaining stated R-value is very important to reducing energy use. This dynamic performance is unique to wool insulation when installed within FOREVERBREATHE SPECIFICATION. Investing in high performance provides long term health benefits and protection from rising energy costs. HBB has all your insulation needs covered with Terra Lana wool insulation.
