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 loss through the floor – as well as noise from the vehicles below and an increased fire risk.  

As such, safety must be a key consideration and the use of fire tested Soffit solutions reduces risk from fire.

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 soffit solutions are designed to offer the utmost protection in terms of fire safety and thermal efficiency. 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

Fire safety is an important consideration, particularly within underground car parks. Fuel from vehicles has the potential to generate rapid rising and very high temperatures in the event of a fire which can compromise the structural integrity of concrete soffits. Specifying fire resistant insulation that is successfully tested and proven to perform can further protect concrete soffits during a fire.

Without proper insulation in the car park’s soffit, 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 UK requirements for fire, thermal or acoustic performance. 

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 cold place. Insulating this area therefore provides good thermal performance to the rooms above, keeping energy bills down.

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