Insulation Rolls vs Insulation Slabs: Which Type is Better in a Partition Wall

There are many factors to consider when insulating a partition wall in your home. You need to think about the climate, the type of insulation, and how much you want to spend. In this blog post, we will compare the two most common types of insulation used in partition walls: slabs and rolls. We will discuss the pros and cons of each type and help you decide which one is better for your needs!

What Are Insulation Rolls and Insulation Slabs

Insulation slabs are made of Rockwool, which is a type of mineral wool. They are typically used in colder climates, as they provide more thermal value than rolls. They are also more dense, which makes them effective as acoustic insulation. However, they can be quite expensive and can take up a lot of space since they don’t compress very well.

Insulation rolls, on the other hand, are typically made from fibreglass. They are less expensive than slabs and can be easier to install. However, they don’t provide as much acoustic insulation value as slabs as they are less dense.

Now that you know the basics of each type of insulation, let’s compare.

Why Use Insulation Slabs?

Using insulation slabs in a partition wall is ideal in colder climates. The mineral wool material will help keep the heat in your home, and the slabs are less likely to sag over time. They also work well as acoustic insulation, and can help reduce noise pollution between rooms.

Why Use Insulation Rolls?

Insulation rolls are a good choice if you’re looking for an eco-friendly option since fibreglass insulation is made from recycled glass.

Insulation rolls are a good choice for warmer climates or for homes that already have insulation in the walls. They are less expensive compared to insulation slabs, and they don’t provide as much of an acoustic insulation value.

Which type of insulation is better for a partition wall?

It depends on your climate, but the main reason to insulate a partition wall is to stop sound travelling between walls. In most cases, Rockwool insulation slabs are a better option for this purpose.

Both types of insulation have their benefits and drawbacks – it’s important to weigh up the pros and cons before you decide which type is best for your home.

Insulation Slabs vs Insulation Rolls

The pros of using insulation slabs in a partition wall are that they’re denser than rolls which makes them perfect material to stop sound transfer.

They are also easy to install, and you can get them in a variety of thicknesses to suit your needs. Rockwool RWA45 is the most popular slab, and comes in 25mm, 50mm, 75mm, and 100mm thicknesses.

Insulation rolls are more flexible than slabs, so they can be adapted to fit different spaces and shapes. However, they don’t provide as good acoustic insulation as slabs.

Knauf provides a range of acoustic insulation rolls, again in thicknesses of 25mm, 50mm, 75mm and 100mm.

Which type would we recommend in your home?

If you’re looking for maximum thermal and sound protection, and don’t mind spending a bit more money, we suggest going with insulation slabs. However, if you’re on a budget and want something that’s easy to install and can compress easily, insulation rolls would be a good choice.

We hope this has helped you understand the pros and cons of both types of insulation. If you have any questions, please don’t hesitate to contact us. We’d be happy to advise you further!
