Are you wondering how to insulate a loft? Loft insulation is a material installed in attics or roof spaces to prevent loss of heat through the roof. It is usually made of fiberglass, mineral wool, or sheep's wool.
With our easy-to-read step-by-step guide on insulating a loft, learn how to insulate a loft the real DIY’ers way and cut costs at every corner. In this article, you will learn:

What is loft insulation and why do I need it?
Loft insulation is a material that is placed in the attic between the roof rafters in order to keep the heat inside during winter and outside during summer. It minimises conductive and convective heat loss, as well as radiation heat loss.
Loft insulation can help to reduce energy costs and your carbon footprint, as well as saving you money by reducing your energy bills.
The benefits of insulating a loft:
- Increased energy efficiency
- Lower energy costs
- Reduced carbon footprint
- Keep your home warmer in the winter
- Keep your home cooler in the summer
Choosing the right material for insulating a loft:
When choosing the right material for insulating a loft, it is important to consider its R-value, or its ability to resist heat transfer. The higher the R-value, the better the material will be at insulating your space.
You should also consider what you want to achieve for the loft, and decide whether you will be using the loft as a living space, or for storage, as this will greatly impact the insulation needs.

DISCLAIMER: This guide acts as a brief outline for loft insulation. Be sure to consult a professional before starting your project.
Measure the width, length and height of your loft, then calculate the total square footage to determine how much insulation is needed for effective coverage. Make sure that you factor in any recessed areas into your measurements.
Ensure that all electrical wiring in the area is securely covered with a fireproof material before laying down any insulation roll. This is particularly important in lofts as these areas are often used for storage, meaning there may be items sitting around which can easily catch fire if exposed to an electrically live environment.
Lay out the first layer of insulation on top of any existing flooring or joists so that it lies flat across the entire area of the loft. Ensure that each layer is cut precisely at each corner or wall junction without overhanging.
Securely fasten the layers by using staples to hold it in place along with any other appropriate materials such as masking tape where necessary; this will ensure that the insulation remains stationary and secure once completed. Repeat this step until all layers have been successfully laid down.
Once all areas have been successfully insulated, check all corners, wall junctions and non-recessed areas for gaps or air leaks that may need additional insulation or further attention.
What are the benefits of loft insulation?
The benefits of loft insulation include increased energy efficiency, lower energy costs, and reduced carbon footprint to name a few.
Can I still insulate my loft if I use it as a living space?
If you’re using your loft as a living space, you should instead opt to insulate the roof as oppose to the attic floor. Learn all about roof insulation and how to insulate a roof yourself here.
