ROCKFLOOR

Floating floor insulation boards provide a barrier to noise and cold temperatures coming from both outside and inside a building.

Installing insulation under floorboards helps to improve thermal and acoustic performance of ground, intermediate, separating and floating floors.

Learn how our high density, stone wool insulation boards lower the carbon footprint of buildings, improve the acoustic performance of their floors – and make them more energy efficient too.

Floating Floor Insulation Products

Why do we need floating floor insulation?

High-rise developments often use floating floors to block unwanted noise from travelling through the floor and reaching occupants below.

Floating floor insulation boards disconnect the surface that is being walked on, from the load bearing floor. This helps to block excess sound travelling through and helps tenants enjoy better sleep, and improved quality of life – thanks to the reduced noise.1

Insulation boards can also be placed underneath ground floor spaces, helping to lessen draughts and block heat which may escape the property – reducing heat loss.

 

Premium floor insulation boards:

  • Reduce noise between floors2
  • Prevent excess energy consumption3
  • Lower heat loss through floor spaces


ROCKWOOL stone wool won’t deteriorate over time. Maintaining its shape and performance throughout the lifespan of a building, it provides insulation for life.4

Calculator and savings

To work out how much insulation you’ll need, determine the m2 surface of the entire floor space. Then, for the required thickness, you can find acoustic reports and required performance levels on our relevant product webpages.

If you need to find out the thermal performance of your construction or renovation, please use one of our U-Value calculators. To reduce energy bills, the insulation of ground floors is often extremely valuable. Adding a thermal insulation layer, in combination with acoustic floor products, can help achieve lower energy bills.

Statistics from the Energy Saving Trust estimate that homes with insulation under floorboards could benefit from annual energy bill savings of:

Detached – £70

Semi-detached – £40

Mid terrace – £25

Bungalow – £60

Case Studies

The project

University Hospital Olomouc’s new intensive care centre became the first healthcare unit in the Czech Republic to be named a zero-energy consumption development.

The Pavilion II Clinic, a five-storey building, was built in 2018.

The solution

The chief architect chose ROCKWOOL solutions for pipes, walls and flooring. They cited the thermal performance of stone wool in the insulation as a way to hit their zero-energy level target.

ROCKWOOL floor insulation boards were part of the package. Resistant to the growth of mould, rot and harmful bacteria, these boards were a natural choice for a hospital setting where hygiene is crucial.

The results

  • Lower energy bills per month
  • Comfortable environment for patients and staff
  • Regulated temperature inside during summer
