The Science Behind Loft Insulation

Some homeowners with lofts that are not insulated have reported losing up to 25% of their heat through their roof.

This is a substantial amount of heat to lose and can be very costly when it comes to energy bills.

Loft insulation is incredibly important when it comes to helping your home retain its heat.

But how does loft insulation actually work?

How Does Loft Insulation Work?

Loft insulation works by adding an extra layer between the roof and the inner framework of the roof.

This extra layer of insulation helps to trap heat inside the house, meaning it can’t escape as easily through the roof.

It enables the air inside your home to remain warmer for much longer, ultimately ensure that the house holds it heat.

Having loft insulation means that you will not have to turn your heating on as much, and can aid in reducing the costs of energy bills.

How Can Loft Insulation Help Reduce The Loss Of Heat?

When your home is heated using a traditional fireplace or stove, or when heated using central heating, much of the heat produced will eventually rise up to the roof and escape.

Scientifically, heat will rise, and unfortunately there is no way of stopping this.

By installing loft insulation, you can help add an extra layer of material that the heat has to rise through.

As loft insulation is thick and is designed to trap heat, the heat will rise much slower through the insulating material, thus reducing the amount of heat lost.

The loft insulation will ensure that your home remains warmer for longer, meaning that you do not need to turn your central heating on as much or for as long.

This can result in massive savings in your energy bill over the course of the year, ultimately saving you up to a few hundred pounds each year.

Keep The Insulation Thick For Better Results

By keeping the loft insulation thick, it will generally further increase the amount of heat that is trapped within your home.

Thicker loft insulation is generally much more effective when it comes to reducing the amount of heat that can leave your home through the roof.

What Are The Best Types Of Loft Insulation?

There are multiple types of loft insulation that can be used when it comes to insulating your loft.

The most common type of insulation used is blanket loft insulation, which consists of rolls of glass, rock, mineral, felt or wool fibre which contains a foil backing and can be easily installed across the back of your roof.

Another common type of loft insulation to use is known as loose-fill loft insulation, which is made from lightweight materials that can be applied to the loft using a spray-on, pressurised system.

It is ideal for loft spaces that are hard to access and contain lots of harder to reach spaces.
