Suspended ceiling Insulation

Suspended ceiling insulation panels, slabs or rolls can enhance thermal performance, reduce sound transfer and reduce the risk of fire spreading.

Suspended ceilings are normally applied beneath concrete floors. They serve many purposes in commercial and residential properties – covering up pipes and air ducts, creating space for light points and forming an aesthetically pleasing finish.

With effective installation, the gap between this construction and the intermediate floor above can be filled with insulation material – whether you have a wooden or metal frame in place.

A suspended ceiling is in many ways considered an acoustic ceiling made from a metal grid with ceiling tiles. Rockfon provides a full portfolio, which also includes solutions for commercial buildings, where Rockfon ceiling solutions are often used to combine the visual and acoustic aspects.

Why do we need suspended ceiling insulation?

Suspended ceilings offer the opportunity to improve the thermal, acoustic, and fire performance of a building – as well as adding design benefits – whether you’re working on a complete new build or a renovation project.

Adding insulation boosts thermal performance by preventing circulated cool air from escaping through the ceiling. This helps maintain a consistent room temperature and reduce energy use – at a time when energy consumption is at its highest¹.

Suspended acoustic ceiling solutions provide extra advantages by reducing noise transfer from adjacent dwellings in the same building.

Key benefits can include:

Reduced cooling costs
Improved fire safety
Acoustic absorption
Visually appealing designs

Calculator and savings

The amount of insulation required depends on the size of the ceiling surface where it will be applied. Calculate the ceiling area to work out how much material you’ll need.

Insulated suspended ceiling panels, slabs and rolls vary in thickness and density. The best size will depend on whether you are prioritising thermal, acoustic or fire performance.

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

Why choose ROCKWOOL solutions?

You’ll find a wide variety of ROCKWOOL products ideal for suspended ceilings – designed to meet and even surpass local requirements.

Rolls and slabs can be easily installed to either cover the area in one go, or be customised where detailed cutting and fitting is needed.

ROCKWOOL solutions significantly boost the thermal comfort of a room. They also reduce the risk of fire spreading, helping create fire barriers in suspended ceilings. In residential properties, stone wool’s acoustic absorption characteristics dampen unwanted noise from neighbours above, as they walk around on the intermediate floor.

Our insulation material can be added and removed without the need for additional fixings, with all ROCKWOOL products fully recyclable to reuse again and again.

Benefits of ROCKWOOL suspended ceiling insulation include²:

Easy installation
Fire resilience
Reduced sound transfer
Thermal properties
Aesthetics
Circularity

Since our stone wool products are usually placed on a suspended ceiling without additional fixings, they are easy to take out and re-use when dismantling the ceiling. Circularity at its best.

Case Studies

The challenge

Solar Spectrum opened new offices, housed within a 38-year-old concrete tower in central Kansas City, USA. Working with Hoefer Wysocki Architecture, they wanted to open-up the space to create a modern office with exposed steel pipes, ductwork and concrete, while reducing noise with the help of effective acoustic insulation.

The solution

The company chose Rockfon ceiling systems and acoustic islands, positioning them strategically throughout the office. This way the existing ceiling elements they wanted remained exposed – but they were able to bring additional acoustic benefits into the space.

The results

Solar Spectrum’s modern offices have a contemporary and appealing aesthetic. The Rockfon panels reflect external light throughout the office – and reduce noise transfer to neighbouring workers from the floor above.

Rockfon acoustic islands were the best thing available to meet the acoustic design and aesthetic needs, and they included recycled content.

Effective ceiling insulation helps to retain heat and absorb sound between separating floors.

Insulation

Basement & Cellar Ceiling Insulation | ROCKWOOL Asia

Basement & cellar ceiling insulation can improve the liveability of converted below ground spaces.

Insulation

Floor Insulation | ROCKWOOL Asia

ROCKWOOL floor insulation is made from premium stone wool and can improve a building’s thermal and acoustic performance.

Installation

Installing ROCKWOOL suspended ceiling insulation is relatively straightforward – whether you have a wooden or metal frame.

Insulation rolls can be placed in the suspended frame and quickly rolled out across the large area in one go. Where possible, it’s easiest to do this before the suspended ceiling finishing layer is put in place.

The same is true when installing slabs. These can be cut to specific sizes, so they fit the frame well.

Key tips:

Consider lights and ventilation – Use a standard cutting knife to make adjustments in the insulation for light and ventilation spots.
Measure the ceiling – The surface area of the ceiling provides the best indication of how much insulation material is required.
Insulate before applying a finishing layer – When applying a board finish to the underside of a suspended ceiling, place the insulation before mounting this in place for easier access.

ROCKWOOL products are also assessed and certified via Environmental Product Declarations (EPDs)⁴. Find these on our local websites or ask our Technical Support teams for more information.

Suspended ceiling insulation can also help meet passive house standards, when applied in residential properties⁵. It improves thermal comfort and airtightness, reducing energy consumption to heat or cool a property, while lowering the impact of external noise pollution on the occupants.
