Basement and cellar ceiling insulation is essential for newly renovated below ground spaces, protecting them from heat loss and nuisance noise.

Using slab and lamella products that are fixed to the underside of the floor above, these spaces can be transformed into comfortable living areas for occupants.

Once installed, stone wool insulation can also improve fire performance – crucial for private housing and public underground spaces such as car parks, where insulation can also be applied.

Discover how ROCKWOOL solutions can raise the thermal, acoustic and fire standards of your next construction or renovation project – creating a space that is energy efficient and safe.

Why do we need basement ceiling insulation?

Whether in private houses, apartment blocks or public parking garages, basement ceiling insulation is needed to protect these underground areas from cold temperatures, raise fire safety standards and shield occupants – or those in the adjacent environment – from nuisance noise.

Because these below ground spaces are susceptible to heat loss and sound transfer, effective insulation can help keep heat in and unwanted noise out – especially if they’re being transformed into a living space.

In both new builds and renovation projects, insulation can improve the acoustic performance of the room and – through increased energy efficiency – lower heating or cooling costs for the people living there.

Calculator and savings

To calculate how much insulation you’ll need for your development or renovation project, you’ll need to work out the ceiling area you are insulating.

Once this has been measured, use this figure to determine how much you should purchase for the job.

Product thickness should be based on desired and/or necessary requirements in thermal, acoustic and fire performance. Local available reports can support this choice.

When installed, ROCKWOOL insulation can start creating savings for you and any building occupants. Learn about energy efficiency

Installation

ROCKWOOL basement ceiling insulation can be installed in several different ways, utilising products and fixings that we supply in our range.

• Using a mortar glue applied to the surface of the insulation, it can be pressed against the underside of the above floor – potentially levelling out an uneven ceiling surface.
• Insulation can also be put into place using mechanical fixings that are first attached to the sides of the insulation boards, then drilled or nailed into the ceiling.
• Selected products can be encased in a concrete floor, using a lost casing method. The floor is poured on top of the insulation and held firmly in place after removing the casing, with ‘pigtails’ applied to the back-side of the insulation.

Sustainability and energy efficiency

The cellar ceiling insulation we produce has a direct impact on reducing energy consumption in buildings.

With more and more urban development projects emerging to cope with the expected two billion growth in the world’s population by 2050, ROCKWOOL insulation can therefore help reduce the energy needed to support this growth5.

Our products are also created using natural materials that are abundant and fully recyclable – and will not degrade in quality6.

Our stone wool insulation solutions are designed to last the entire lifetime of a building – protecting and helping your renovation or development throughout its existence, without any dip in performance7.

FAQs

Should I insulate my basement bathroom ceiling?

Basement bathrooms can create issues with sound transfer, like any other room in a basement or cellar. Insulation can help reduce noise pollution from showers or other bathroom appliances in shared living spaces.

Does a basement ceiling need a vapour barrier?

Installing a vapour barrier is optional when utilising ROCKWOOL solutions, as stone wool insulation is water repellent. However, adding a vapour barrier can help to prevent additional moisture coming through the ceiling space.
