SheepWÜL is comprised of soft fluffy sheep wool, recycled newspaper, and borates. All is sustainable, recycled or natural. Our insulation does not contain petroleum products, and does not require considerable energy to manufacture.

No Hazmat suit required, no potential off-gassing, no petroleum based chemicals, just a thoroughly tested blend of simple materials.

Leave your drywall intact, SheepWÜL can be installed from the exterior with existing machines, using a process that has been around for decades. SheepWÜL’s density allows it to fill into gaps left by dilapidated or non-existent insulation too.
