How Many Rolls of Standard Loft Insulation Do I Need?

There is no definite answer to this question. Each loft has different dimensions and therefore, different insulation needs. We suggest that you measure the width and length of the areas that you want to insulate to work out the m2. Then divide the total number of m2 by the size of the roll. From this, you can work out how many rolls you would need. We always recommend allowing between 5-10% for wastage. If you are unsure, feel free to get in touch with our insulation experts and a member of our friendly team will be happy to help.We also recommend using rolls that come pre-perforated. Pre-perforated rolls allow you to choose between using the full width roll or splitting it into a length that better suits your needs. This helps to maximise on site efficiency. Uncut rolls offer the versatility of being trimmed to fit between joists, or you can utilise them as full width rolls for a swift installation process.

How to Cut Loft Insulation Rolls?

You can cut rolls in a few different ways based on the width and length of your space. You can use a utility knife, a carving knife, or even shears. Always mark your measurements on the roll before you begin cutting.Before you get cutting, we recommend wearing goggles, aprons, and even protective glasses. If you are concerned about safety precautions, always consult with a professional.

What Is The Difference Between Combi Cut & Ready Cut?

Combi-cut rolls come with partial perforations, allowing you to either fit them between joists or use them in their full-width roll form, optimising your on-site workflow. Meanwhile, ready-cut products are tailored to size, ensuring seamless and efficient installations.

How to Install Loft Insulation Rolls?

One of the benefits of loft insulation rolls is that they are very easy to handle and install. The real work starts when you inspect your roof and loft for signs of rot and deterioration. Before installation, you should always check your joists to make sure that they are safe to stand on.We also recommend checking whether the back end of the light fittings from rooms below protrude into the loft. You should cover them with downlight covers so that they do not overheat.Next, you want to lay the insulation between the joists. Once there is a layer of insulation between your joists you should lay another layer across the top in the opposite direction. It is important to not leave gaps between the rolls or to allow them to overlap so that you can ensure maximum thermal efficiency.It should be noted that you can lose up to 5% of the heat in your home through your loft hatch. You should cut two pieces of insulation roll to match the size of the hatch. Staple them in place and attach draught-proof strips to the outside of the hatch to reduce heat loss and heating bills.It's common to board your loft once you have insulated it, so you may need other building materials such as chipboard flooring.

What The Different Types of Loft Insulation?

Mineral wool: This is a popular choice and looks a bit like wool, but it's made from molten glass or rock. It is often referred to as glass wool and offers good thermal performance in a host of applications. You can find plenty of glass mineral wool roll solutions on our mineral wool category page. Fibreglass: A type of fibre primarily composed of glass. PIR: Rigid insulation board can be used to insulate almost any part of the home, from the roof to the foundation. Whether you're looking to insulate cavity walls or your basement, PIR has you covered. Sprayed foam: Expanding foam that can be sprayed into a space.
