Separating Floors

Separating floor insulation helps to maintain a comfortable indoor climate by reducing airborne and impact sound, preventing the inefficient heat transfer between floors and providing the necessary fire resistance, required by Building Regulations.

Installation

ROCKWOOL floor insulation can be installed by a professional industry tradesperson, to prevent heat and noise transfer and to improve fire protection.

If installing yourself, you should carefully follow the product installation guidelines, which are available on our product web pages.

Key tips:

  • Identify the type of floor you’re insulating – this will affect which product you’ll need.
  • Determine the acoustic and thermal performance levels – this will also help you choose the correct product.
  • Locate where you want to place the insulation – prepare the area for installation by making sufficient room around you.
  • Accurately measure the width and thickness – do this in between joists before purchasing and installing.
Inspiration and guides for professionals

Calculator and savings

To work out how much insulation you will need, measure the length and width of your floor space to calculate the area’s m² value. You may want to order slightly more to allow for some excess.

When fitting in-between joists, make sure you select the proper width as this might affect the amount of product you want to purchase.

Work out how resistant your floors are to the flow of noise with our local available Acoustic Calculators and reports.

Use our ROCKWOOL U-value calculator to determine the thermal performance of the building’s floors and possible cost savings. For more details on technical specifications, visit our ROCKSPEC Specification Toolkit.

Case study

The challenge

Property developer Keywest 3 converted an empty high-rise office complex into 43 luxury flats in South Shields, UK.

This ambitious renovation project aimed to minimise noise travelling between apartments, and to improve the building’s wall and underfloor insulation. Originally, the company planned to use 50mm glass wool insulation.

However, the team at Keywest 3 changed their mind after an on-site demonstration of ROCKWOOL floor solutions, which showcased superior acoustic properties and met all of their criteria.

The solution

Keywest 3 picked ROCKWOOL FLEXI® 50mm for this project, deciding to double the material to bolster the sound insulation of the development.

The result

  • Building regulation requirements for soundproofing were surpassed
  • Resident comfort and fire safety were enhanced
  • Thermal efficiency was improved – resulting in reduced tenant energy bills
