What are Insulation Rolls? 

Insulation rolls are long, continuous rolls of insulation material that provide thermal resistance and improve energy efficiency in buildings.

Highly versatile, they can be installed in various parts of a building structure, such as walls, ceilings, floors, or attic spaces, to reduce heat transfer, maintain indoor temperatures, and enhance overall comfort.

Predominantly, insulation rolls are 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.

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. 

What's more, 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. 

Where Are Insulation Rolls Used? 

  • Timber Frame Separating Walls
  • Timber Frame External Walls
  • Internal Timber Floors
  • Internal Concrete Floors
  • Timber Separating Floors
  • Roof Junctions
  • Partition Walls


Benefits of Using Insulation Rolls 

  • Effective thermal insulation
  • Energy cost savings
  • Enhanced indoor comfort
  • Sound reduction
  • Moisture control
  • Fire resistance (depending on material)
  • Versatile and easy installation
  • Long-lasting performance
  • Reduced environmental impact


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.

Applications

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


Acoustic Insulation Rolls

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.

Applications: 

  • Separating walls and floors
  • Internal walls and floors
  • Timber and metal stud partitions 


Knauf Insulation Roll 

Knauf Insulation Roll is made using glass fibres that are woven together to form a soft wool. 

Knauf promises ‘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.
