Concrete Deck Insulation

Find products

Concrete deck insulation can greatly enhance the energy efficiency of your building. In an uninsulated or poorly insulated property, a great deal of heat is lost through the roof¹, making it an especially crucial area to focus on.

ROCKWOOL concrete flat roof insulation provides excellent thermal, acoustic and fire resilient benefits, helping to create a more comfortable living or working space within².

Not only does the use of our products help to lower energy bills and reduce health risks³, but by reducing the energy needed to heat or cool the building, our premium-quality stone wool insulation also helps to cut carbon emissions too.

Why do we need concrete deck insulation?

Concrete deck structures are typically used in connection with larger industrial, commercial or institutional buildings. However, they are also becoming increasingly popular in residential designs – including individual family houses.

As a valuable addition to this building design style in towns and cities across the world, quality concrete roof insulation can provide extra protection from overheating in warmer climates and cold temperatures in cooler regions.

This raises energy efficiency, and provides great long-term value and sustainability for constructions.

Relevant resources

Calculator and savings

How much insulation you’ll require depends on the size and shape of your project. Since there is usually no limitation to the installation height on a roof, insulation thickness can be adjusted to your specification – and to reflect the local regulatory energy demand.

Use the tools and calculators available in your local market to work out the potential cost savings you could make.
