Car Park Ceiling Insulation

Effective insulation plays an important role in making urban car parks more energy-efficient and less disruptive to their surroundings.

To save space in cities and towns, car parks are now commonly designed to sit below residential and commercial buildings, which means the properties above can be susceptible to heat gained through the floor – as well as noise from the vehicles below.

This is especially true when you consider that car parks are constructed to deal with large volumes of traffic in wide-open spaces.

ROCKWOOL’s car park ceiling solutions – including stone wool below concrete soffit insulation – are designed to offer the utmost protection in terms of fire safety, thermal efficiency and acoustic performance. Read on to learn more.

Why do we need car park ceiling insulation?

Car parks tend to be especially noisy built-up spaces. This makes it essential to protect both the properties above – and surrounding public spaces – from the sound of high traffic levels throughout the day. The World Health Organisation (WHO) has reported that excessive traffic noise can have a detrimental impact on people’s health¹.

Other major considerations include fire safety. The chances of a fire spreading through the car park and into the properties above can be significantly reduced using effective insulation that’s fireproofed to the highest standard.

Without proper insulation in the car park’s ceiling, the buildings above are also susceptible to energy loss through the floor.

Calculator and savings

When you’ve found the ideal ROCKWOOL insulation product for the job, you’ll need to figure out how much of it you’ll need.

Product thickness should be based on local requirements for fire, thermal or acoustic performance. Consult your local market calculators and pages for more information.

Like any other space that is in contact with the outside environment, but especially given their ‘sunless’ position, underground car parks can be a particularly hot place. Insulating this area, therefore, provides good thermal performance to the upper rooms, keeping energy bills down.

It also helps protect your property and its surroundings – thereby increasing the potential value of the area.

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?

Our stone wool car park ceiling insulation range offers high density slabs or lamella – designed to assure fire protection and acoustic sound absorption to the highest standards. Increased thermal performance of the construction is an additional benefit.

ROCKWOOL insulation products are tested to the highest levels of fire safety.

Our products also offer effective acoustic protection in a variety of settings. Stone wool provides tremendous absorption of sound², meaning occupants of the spaces above and around the car park won’t be disturbed by the comings and goings below.

ROCKWOOL products are also:

Easy to install. Workers will have no problems installing the slabs due to their ease of use.
Our circular business model means the materials used in new projects are recyclable³.

Aside from the acoustic, thermal and fire safety benefits, we also look to offer great visual performance as well – especially important for spaces in shopping malls or leisure complexes.

Products can be supplied with regular re-paintable surfaces, pre applied coatings or finishing layers.

Installation

Where possible, use ROCKWOOL fixing materials and accessories for proper installation.

Follow local regulations and working methods to obtain the best performance – and to ensure you achieve the requirements you are aiming for.

Key tips and information:

Products are commonly glued with a mortar applied to the surface, similar to how ETICS products are applied to a wall with a basecoat mortar. The backside surface of the ceiling slab is covered with mortar and firmly pushed and placed against the underside of the floor. Some irregularities of the floor can be evened out, creating a levelled ceiling surface.
Mechanical fixings can also be used, drill-fixed or nailed against the floor. Here adjustments can be made to create a smooth surface layer.
Work tightly around penetrations to assure proper performance in these often difficult to reach spots.

Sustainability and energy efficiency

By installing ROCKWOOL insulation, you can have a direct impact on energy consumption. Utilising our products will benefit the properties situated above the car park by reducing the amount of heat lost through the floor – and therefore the amount of energy required to heat them.

Stone is one of the planet’s most abundant natural materials. Our products are fully recyclable, reducing waste⁴, and are designed to last a building’s lifetime.

They also help absorb car noise and reduce the impact of sound pollution on the wider environment – improving the acoustic quality of people’s surroundings.
