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.
