Why do we need floor insulation?

Floors in buildings are magnets for sound and heat to travel through. This can cause long-term issues for tenants and owners, such as nuisance noise, high energy bills, and warmer living conditions.

These problems are becoming ever more common. By 2050, it is expected that more than 50% of the world’s population will be living in cities – a prime location for noise disturbance.

Correctly insulating floors below, in-between, or on top of, wooden, metal or concrete constructions can help to overcome these obstacles.

Optimum insulation can help to:

Block out unwanted noise
Reduce thermal transmission through floors
Improve a building’s energy efficiency

Premium ROCKWOOL stone wool floor insulation does this over the lifespan of a building – without deteriorating in performance.

For wooden floors meanwhile, the non-combustible properties of our stone wool product range help to increase fire safety levels.⁵

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.

Why choose ROCKWOOL solutions?

ROCKWOOL floor solutions use stone wool.⁶ Made from abundantly available natural rock, our products’ fibre structure insulates buildings effectively:

A1 classified – ROCKWOOL insulation is non-combustible up to 1000°C.
Thermal regulating – steady temperatures are maintained by trapping air in the stone wool fibres, reducing air and heat flow through flooring.⁷
Sound proofing – acoustics from above or below can be blocked out and absorbed, helping to improve quality of living.⁸

Adaptable for architecture – various sizes are available, with flexible edges making installation easy.
Robust – throughout the lifespan of a building, ROCKWOOL floor products won’t sag and will maintain their insulation performance.⁹
Sustainable – our stone wool can be recycled.

Our floor applications range from thermal products that reduce energy bills, to acoustic products that substantially reduce sound going through a floor. All are designed to help you stay comfortable and safe.

Applications

Insulation

Floating Floor Insulation | ROCKWOOL

ROCKWOOL floating floor insulation boards can transform the thermal and acoustic performance of ground, separating and intermediate floors.

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

Once installed, ROCKWOOL products can achieve optimal performance. They meet, as well as go above and beyond, building requirements.
