Acoustic Insulation

Shop our range of Acoustic roll insulation including glass and stone mineral wool insulation from Key insulation brands such as Knauf, Isover and Rockwool. Our selection of Acoustic insulation is intended to increase the acoustic and thermal insulation of partition walls, ceilings, floors and roofs by absorbing sound waves and reducing noise transmission between spaces.

Mineral Wool insulation is also known for its fire-resistant properties, making it a popular choice in construction for both its acoustic and safety benefits. Additionally, it's relatively easy to install and can be used in various forms such as batts, boards, or loose-fill insulation


What is Acoustic Roll Insulation?

Acoustic roll, also known as sound insulation roll or acoustic insulation blanket, is a type of insulation material designed to reduce the transmission of airborne noise between rooms or floors in a building. Typically made from materials such as mineral wool, acoustic roll comes in rolls of varying thicknesses and densities. To install acoustic roll, simply roll it out evenly between the joists or studs in walls, floors, or ceilings, ensuring it fits snugly without any gaps. Our most popular acoustic roll is manufactured by Knauf and Isover, and is made from a glass mineral wool.

What Sizes Does Acoustic Insulation Come in?

Our acoustic insulation is available in a variety of lengths and thicknesses, but the common theme across most brands is their width, as they are specifically sized at 600mm to fit between the studs in most modern stud walls. The most common thicknesses are 25mm, 50mm, 75mm and 100mm. When selecting a thickness, choose the closest size to the depth of your cavity - try to avoid more compression than is necessary. 

How to Calculate U Value

The U-value (thermal transmittance) of a building component such as a wall, roof, or window, measures its thermal conductivity or how easily heat can pass through it. The lower the U-value, the better the insulation. To calculate the U-value, you typically need to consider several factors, including the materials used, their thicknesses, and any air gaps. A general formula for calculating the U-value:

U = 1 over R


U = U Value

R = The total thermal resistance of the building component, including all layers of materials and air gaps.

However, with Acoustic insulation, some manufacturers do not supply a R value, as the primary focus of the product is acoustic performance rather than thermal, and it is therefore not tested against that criteria. Though virtually all acoustic insulation will have some thermal insulating properties, Acoustic insulation should be selected where sound resistance is the primary goal, rather than thermal.
