I cannot rate this product highly enough. There is no going back to the unpleasant stuff. It was, and continues to be, a pleasure installing sheep’s wool. Fast, efficient, clean, effective. I have undertaken a sustainable, self-build and need to hit all the ‘u’ buttons. Speed is important and involving family is essential to keep costs down. Sheep’s wool has acoustic, fire retarding, damp controlling and has impressive insulating properties. Easy to cut, size and install in standard and unusual wall, loft and ceiling spaces. I like to think I am giving British farmers a means of generating income and preventing the next generation from have to deal with my non-biodegradable building products. Buy with confidence and without hesitation.
