What are Insulation Rolls? 

Insulation rolls are a type of blanket insulation, which are suitable for a variety of building applications, including floors, walls, lofts and roofs - pretty much any part of the building structure. They are both soft and flexible and can be cut to size with a simple utility knife and fitted into place with staples or other fixings. Insulation rolls are purposed to reduce heating bills and boost indoor comfort - making your home cosier and cheaper to run in the long run.

Types of Insulation Rolls

Loft roll insulation and acoustic roll insulation are the two most widely used insulation rolls on the market. Insulation rolls are most commonly made from either glass mineral wool, mineral rock wool or sheep's wool.

Glass mineral wool products are geared more toward thermal performance - making them the go-to choice for those wanting to bump up the temperature in their home and reduce energy bills. Whilst rock mineral wool products (such as Rockwool RWA45) tend to exhibit stronger acoustic benefits. Rock mineral wool also works excellently when it comes to insulating cavity walls. 

Loft Insulation Rolls

Loft roll is a form of fibreglass insulation, otherwise known as glass mineral wool insulation.
As its name would suggest, glass mineral wool insulation is made of glass and a bonding agent which are manufactured together to create a flexible and air pocket-filled product. 

These small pockets trap gas (a poor conductor of thermal energy), ensuring heat is trapped in the insulation, thus preventing it from rising through the roof. Effective roof insulation helps you to keep energy costs down; with a thermal conductivity of 0.044 W/mK, loft insulation rolls are the perfect energy-saving companion.

What's more, loft insulation rolls are also non-combustible and achieve the highest possible level of fire performance with an A1 rating on the Euroclass scale.


  • Laid in attic spaces
  • In-between and over floor joists and beams
  • Pitched roofs at ceiling level 
  • Loft floors

Should your project require it, we also stock popular loft rolls like Knauf Earthwool Loft Roll 44 and Isover Spacesaver 44 Loft Insulation rolls.

Acoustic Insulation Rolls

Simply put, acoustic roll is an insulation roll which inhibits the transmission of sound. Unlike the majority of insulation products (which are purposed to protect against heat loss), acoustic rolls, as the name would suggest, are designed to reduce the volume of noise from both inside and outside your home. Otherwise known as acoustic partition rolls, these rolls are primarily designed for use in walls, floors and partition walls.

Acoustic roll is commonly made from fibreglass (otherwise known as glass wool) and exhibits high acoustic performance thanks to its manufacturing process. The way in which recycled glass is spun results in a product that is packed with tiny air pockets. These pockets trap sound and prevent it from getting through the material.

Knauf Insulation Roll 

Knauf Insulation has over 40 years experience in the insulation industry, and is considered one of the major brands of fibreglass insulation. Knauf Insulation Roll is made using glass fibres that are woven together to form a soft wool. They contain Knauf's special ECOSE technology, which makes the rolls softer and less irritable than those of other manufacturers. The two most popular products in the Knauf Insulation roll range are the Loft Roll 44 Combi-Cut and the Acoustic Roll. 

Knauf promise ‘smarter choices’ to people who want to invest in premium-quality thermal and acoustic insulation. The Earthwool range contains premium sound-deadening insulation such as the acoustic roll. For friction fitting between resilient timber battens and timber studs in robust detail separating floors and walls, check out Earthwool Acoustic Roll. 

Frequently Asked Insulation Rolls Questions

How Thick Should Loft Insulation Rolls Be? 

Current building regulations stipulate the need for at least 270mm of insulation thickness in a loft to meet the required U-value of less than 0.16w/m2k. 

For an existing building use 250mm. For added performance in an existing building or for a new build use 300mm.

You should always consult insulation experts when installing and insulating any applications. They'll advise on how to install and what other building materials will be needed to complete a project.

What is the Thermal Conductivity of Acoustic Roll?

Acoustic Roll is not assigned a specific thermal conductivity as it is produced to meet the min 10kg/m3 as per building regulations. As its name would suggest, the product is purposed to perform acoustically as opposed to thermally, although there will be slight thermal benefit from installing acoustic rolls.
