Ground to floor solutions and effective concrete floor insulation prevent unnecessary heat loss in buildings. They can help to maintain a comfortable temperature and improve energy efficiency.
Without under slab insulation, the direct contact from the floor to the ground makes it an easy route winter cold to get in.
Insulation can be installed above or under concrete slabs to improve thermal efficiency, with around 30 percent of all heat in homes lost through the floor.
Concrete slab insulation between the ground and the floor is vital to create a comfortable living environment. Not only does it make a building more energy efficient, it also helps to create cosy, comfortable and habitable conditions for people living or working there.
Some of the main benefits of under slab insulation include:
Costs and savings will vary depending on several different factors. But the initial cost of insulation will be outweighed by the savings made over time on energy bills.
Installing concrete floor insulation can significantly reduce heating costs over a building’s lifetime. The slabs can also be used again in other projects if the building is demolished, making them an investment for future projects.
Concrete insulation is placed underneath a floor in between the building’s foundations. Calculating the size of the surface area will directly provide the m2 needed. The m2 measurement of floor equals the m2 of insulation required.
For more information, a locally available U-value calculator can help determine the insulation type and thickness required for your project.
ROCKWOOL concrete slab insulation is strong and durable, lasting for the lifetime of a structure1.
As the insulation sits under the weight of the floor, its compressive strength makes it ideal for both domestic properties and commercial premises, where heavy product displays – for example – can weigh down on the floor2.
The energy efficient properties of ROCKWOOL products are what makes them such a great choice for your project. As ground to floor insulation helps to prevent any cold getting inside your building, it creates a comfortable living or working space, reducing heating costs at the same time.
The benefits of choosing ROCKWOOL concrete insulation include3:
Concrete slab insulation is simple to install once you’ve measured up the surface area of your building and got all your equipment ready.
Key tips for installing insulation under concrete slabs:
ROCKWOOL insulation products are fully recyclable. Since ground to floor slabs are usually ‘loose laid’ on the ground, the slabs can easily be taken out and reused.
Ground to floor insulation is mainly used in new build projects – and one of our company’s key values is helping to make our towns and cities as sustainable as possible for future generations4.
This is why all of our insulation is made from one of the most abundant natural materials in the world: stone5. It also lasts for the lifetime of your building, making it a sound investment for the future.
Concrete slab insulation can also be used to ensure your building passes international standards and meets – or surpasses – regulations in local markets.
