Concrete Deck Insulation

Our products help to lower energy bills and reduce health risks

Concrete Deck

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 gained 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 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.

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

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 our ROCKWOOL U-value calculator to determine the thermal performance of the building’s roofs and possible cost savings. For more details on technical specifications, visit our ROCKSPEC Specification Toolkit.

Why choose ROCKWOOL solutions?

ROCKWOOL insulation provides robust energy efficiency and enhanced protection from the elements. Made from volcanic stone rock⁴, our products are designed to ensure that your construction will be both comfortable and sustainable.

ROCKWOOL wedge systems, sometimes known as ‘cut to falls’, also allow you to maintain efficient roof drainage in your concrete deck structure. This ensures your project is fulfilling and surpassing key requirements – across a range of local conditions and regulations.

Stone wool insulation can also help protect against the risk of fire, and insulate against nuisance noise.

Key benefits of our concrete roof insulation include:

Energy efficiency – stone wool insulation helps regulate temperatures inside your building, helping to reduce fuel costs and energy bills.
Fire safety – our insulation is non-combustible, resistant to temperatures above 1,000º C⁵, and acts to slow the spread of flames and smoke while meeting or surpassing local market classifications.
Acoustic blocking – the dense properties of ROCKWOOL insulation block out unwanted sounds and offer added noise protection.
Easy to install – our products are simple and convenient to fit, and can be tailored to a range of building types and shapes.
