K Systems
Converting or upgrading your attic into a room requires insulating multiple surfaces without sacrificing floor space or headroom. Our specialised systems provide seamless thermal protection for every surface:
Loft Roll
Green Loft
Up to 25% of your home’s heat escapes directly through an uninsulated roof. Whether you have an unused loft void or a fully converted attic room, EZY-FIT has a tailored solution.
M IWI Internal Wall
K Internal Wall
Green IWI
Uninsulated solid brick or stone walls account for up to 35% of total household heat loss. EZY-FIT provides complete, space-saving internal wall solutions tailored to any property type across every floor.
UFI
The Ezy Fit underfloor insulation is made for suspended timber floors, which have a gap underneath. This gap can vary in size, sometimes as large as a cellar. Savings can be around £40 per year and you gain a more comfortable room.

“It’s always a pleasure using Ezy-Fit, over 3 years we’ve installed IWI in more than 1000 properties using their systems”
What VERFIED customers say
“It’s always a pleasure using Ezy-Fit, over 3 years we’ve installed IWI in more than 1000 properties using their systems. Most have been straightforward, but Darren has always been available for technical support & advice if we came across anything that left us scratching our heads.
They are very quick to arrange training and their on-site visits are a great help, I would heartily recommend them.”
