Loose fill insulation is increasingly preferred amongst industry leaders in the built environment. Havelock Wool loose fill insulation is widely used in residential and commercial construction applications that require superior thermal, moisture and acoustic insulation. Havelok Wool loose fill insulation is comprised of 100% wool and no synthetic mix. The loose fill is made of small balls, which are hugely effective at trapping air while avoiding slump once installed. Havelock Wool loose fill is all-natural, renewable, and sustainable in its production while being compostable at the end of an extended useful life. Wool is inherently self-extinguishing and manages moisture against 65% relative humidity. Havelock Wool loose fill exceeds the R-values of all other insulation mediums (except the most toxic: spray foam) with an R-value of 4.3 per inch. Loose fill insulation is a more recent entrant into the insulation market. Installation begins with a membrane placed over open stud bays, or a hole poked in an existing wall, and insulation is blown in behind. The perfect insulation for a healthy home.
