How Does Loft Insulation Work?

If you’re a homeowner, then the chances are you’ve looked into your loft and taken note of the insulation found there. 

This stuff is vital for your home because it provides thermal insulation. But if you’re not sure exactly how insulation works or what the benefits are for your home, not to worry; this month at Loft Storage Rooms, we’ll talk you through everything you need to know about loft insulation.

How does my loft insulation work?

Throughout the colder months in the year – and let’s face it, there are quite a few of those – you’ll no doubt have your heating on. Any warmth you have when it’s cold, whether naturally generated or provided by central heating, is something you want to keep. 

Heat, however, always rises, which means many uninsulated or poorly insulated properties lose heat through their roof. That’s because the warmth goes through your ceilings, up into your loft and out through your roof. This is the second law of thermodynamics, the main gist of which is that heat will always try to redistribute itself to colder areas.

With insulation in place in your loft, particularly over the boards in your loft, more of that heat is retained in the rooms below, as the warmth of the air is unable to escape as easily through the material.

What is loft insulation made of?

What loft insulation is made of is crucial to how it performs. Most modern insulation is made from materials that prevent the conduction of heat from below. This stops the heat from being transferred upwards and out of your home.

Loft insulation is commonly a fibre of some sort with a foil backing. This fibre layer, varying in thickness depending on the manufacturer, is what prevents a loft from warming up as the heat is blocked.

  • ROCKWOOL insulation, for example, is made from ‘a rock-based mineral fibre’, created from melted components that are spun into a wool material. This is then laid in your loft space, creating the barrier required to retain more heat in your home.
  • Solarshield is double-sided reflective foil insulation, with a thinner fibreglass core, so while this material has a high fire rating, it’s also excellent at reducing the amount of heat lost through your loft space.

The benefits of loft insulation

Having loft insulation in place is not just a great idea for the winter months coming, but for long into the future. Here are just some of the loft insulation benefits you can expect if you’re adding insulation or upgrading:

  • Lower heating bills – the better your home is insulated, the less you’ll have to rely on your heating
  • Better energy efficiency – the heating you do use will go a lot further since it will be retained for longer, giving your home a better energy rating and lowering your carbon footprint
  • Increased property value – with the best performing loft insulation in place, your home will be more attractive to prospective buyers
