Applications

Blown-in sheep wool insulation from Havelock Wool can be installed as blown-in (loose fill) insulation in attics, as well as blown-in behind INTELLO Plus or netting in walls, floors and cathedral ceilings. Made from high quality wool in USA.

Sheep have been adapting to severe climatic environments for thousands of years. Over such time, their wool has evolved to offer protection from the elements of each season – hot and cold; damp and dry. Over generations, people have come to understand the benefits of wool and created numerous applications for its inherent advantages. Wool’s five follicles and natural crimp, trap air, moisture and harmful chemicals so as to improve air quality while keeping warmth inside during winter and outside over the summer months. Wool is a natural insulator but only minimally applied to living spaces – until now.
