Intermediate Floor Insulation

You can install intermediate floor insulation in both new build and renovation projects, using light to medium-weight slabs and rolls. A variety of products are easily applicable in the low to mid density range. 

• Wooden floor – Place the chosen product between the floor beams. 

• Concrete floor – Install against the underside of a concrete floor. Use regular, available mechanical fixings or cement glue for long-lasting adhesion.

Insulation rolls can be cut to size or even produced at a width that fits perfectly between floor beams, while slabs are available with or without a flexible edge for friction fitting.

Key tips:

• Choose the best product – Products with flexible edges are easily installed, but if cutting is required, ensure you have extra width.
• Remember aesthetics – For concrete floors especially, a mechanical fixing or glued application can affect the aesthetics of the room, so it can be common to apply a lowered ceiling for visual perfection. 
• Consider the floor beams – If granulate is used to fill in between the wooden floor beams, this requires tiny holes in the construction to enable proper installation.

Sustainability and energy efficiency

All of our ROCKWOOL separating floor insulation products are recyclable. They are made from one of the most abundant natural materials around – stone⁴.

Mid floor insulation is designed to last the lifetime of a building, whether it’s installed in a brand-new property or used to renovate an existing one. 

It also provides thermal benefits to help promote indoor comfort, and meet modern building targets for energy efficiency.
