Collection: Underfloor Insulation for Steel Joists - Joisties

Underfloor insulation will reduce your energy bills by 20% while significantly improving the comfort of your home.   Steel framed floors can be particularly cold and have specific fixing challenges.  

Joisties is an elegantly simple DIY system that not only hold the insulation in place, but also insulate the steel joists to reduce thermal transfer.  Purpose made fitting tools and “stick once” glue make it a snap to fit your Joisties to the underside of your steel joists. No matter if your joists are “C” sections or box sections, Joisties have you covered.

Think of them as socks for your steel joists.
