Frequently Asked Questions
What are Insulation Rolls?
Insulating a cavity wall, floor of loft space can be a tiresome endeavour. Whilst traditional insulation slabs are incredibly efficient, they can be difficult to handle and challenging to cut. Insulation rolls on the other hand, are highly flexible and come conveniently sized to suit a variety of applications.
Benefits of Insulation Rolls
There are several benefits to using insulation rolls in your home. They’re a very popular choice amongst homeowners looking to make their home more comfortable while minimising utility bills.
Loft insulation rolls boast fantastic thermal insulation. This is thanks to the medium density materials used in their manufacture such as mineral wool, which are specifically designed to retain warm air.
In addition to their excellent thermal insulation, their porous and non-directional fibres also provide great acoustic insulation. This makes loft insulation rolls an ideal choice for noisy streets or towns. Insulation rolls are also generally provided pre-split, meaning you can easily install them between the rafters of your loft or frames in your walls.
Varieties of Insulation Rolls
There are several different varieties of insulation roll, not only varying in material and composition but also thickness. Common materials found in loft insulation rolls include mineral wool and low-emissivity foils. Mineral wool insulation rolls are also shown to offer excellent thermal insulation.
According to the Mole Valley District Council, installing 270mm of insulation into your loft could reduce your home’s CO2 emissions by up to 720kg. We also stock loft insulation rolls that come with a foil facing. This helps to reflect unwanted heat during the summer while retaining warmth inside during the winter.
The combination of proven materials such as mineral wool and innovative features such as foil used in modern insulation rolls offers unrivalled efficiency for energy-saving households.
How Do You Cut Rolls of Insulation?
While loft insulation rolls are generally supplied in conveniently sized widths, it may be necessary for you to cut them to suit the spacing between your timber frame. You’ll need to wear protective clothing and have a sharp utility knife to hand before following the steps below.
- Wear a protective dust mask, eye protection, and gloves. If possible, wear coveralls or a long-sleeved shirt to protect your arms.
- Measure and take note of the spacing between the studs of your attic, floor or wall. Then roll out your insulation on a flat surface.
- Use a straightedge to mark out where you’ll need to cut. If possible, use a level to ensure your line is straight and prevent any angles.
- Whilst being careful not to compress the insulation, use a sharp utility knife to cut through the insulation. You may need to slice several times.
How Often Should You Replace Your Insulation?
Insulation will begin to settle after a year, at which point its fibres will provide less thermal efficiency. Insulation can also become damp in poorly ventilated loft spaces.
Whilst this doesn’t necessarily require you to replace your insulation rolls, it could have a negative impact on your home’s insulating properties.
Refer to EnergyStar’s guide to inspecting your insulation. It reveals how to check your attic and wall insulation throughout its lifespan.
Can I Get Free Rolls of Insulation?
The ECO Scheme is a government initiative to combat fuel poverty and reduce carbon emissions. The scheme requires energy suppliers to assist in the introduction of particular efficiency measures in homes across England, Wales and Scotland.
To be eligible you must be part of the core group within the existing WHD Scheme or receive an eligible benefit whilst meeting the relevant income requirements. A complete guide to the requirements can be found on the Ofgem website.
