It's easy to install and helps you to lower energy bills, by improving the energy efficiency of your home. As a result, this can also have a positive effect on the overall value of your home.
What is loft insulation?
Loft insulation creates a barrier of material within the structure of the roof to slow down the transfer of heat between outside elements and your home. This helps to keep your entire house warmer during the winter months and cooler during the summer, boosting all-around energy efficiency.
How does loft insulation work?
Lofts will either be insulated using a glass mineral wool quilt or foil-backed felt. In many respects, insulation works as a blanket to retain warm air circulating around your home. Loft insulation is usually installed in-between the ceiling joists to prevent the heat from rising into the loft area.
What is the best insulation for lofts?
Knauf products are generally considered the best and the Knauf Earthwool Loft Roll offers high levels of thermal resistance and low rates of thermal conductivity (0.044W/mK). Fire retardant properties also place it in the highest Euroclass A1 reaction class.
How to insulate a loft
Installing Knauf insulation quilt products can be easily completed following these steps:
Clear the loft space so it is ready for installation.
If you have pipes and a water tank in the space these must be lagged to retain their heat so they do not freeze. This is because the loft becomes cooler once the insulation is installed.
Any electrical wiring will need to be above the insulation, ensuring the wires are not stretched. You may need a professional electrician to help with this.
Ensure the insulation material has a depth of at least 270mm.
Unroll the insulation and carefully place it between the ceiling joists. Use scissors to cut to size and avoid tearing or stretching.
The second layer should be at a right angle to the layer below. If the first layer is 200mm, the second should be 100mm.
If you are planning to install insulation in the ceiling, ensure that two layers are used, with one at the right angle to the other.
How much loft insulation do I need?
The easiest way to calculate how much insulation you need is to measure the length and width of the loft in metres. Once you have both figures, multiply them together which will tell you the square meter (m2) of the space. This will tell you how much loft insulation material to buy.

FAQ
All of our C16 and C24 graded timber is regularised
Regularised timber is timber that has been processed to have a uniform shape and size. This means that the wood has been sawn and planed to remove any irregularities and ensure that each piece of wood has consistent dimensions. Regularised timber is often used in construction, particularly in the framing of buildings, as it is easier to work with and can be more efficiently installed than irregularly shaped timber.
We have one of the largest ranges of timber lengths, dimensions and grades available to buy online.
The variation you require will determine the exact lead time and delivery method.
Most orders arrive within 3-4 days, the maximum is 7 days. Please get in touch before you order if you need a specifc delivery date.
