By fully insulating your loft, you can save as much as £215 each and every year on your energy bills, as it works to keep your property so much warmer. This is an easy fix to do in order to make your home much more energy efficient, but it can be quite confusing given how many different types of loft insulation there are on the market.
In order to make this a bit more clear, we have put together this handy guide on the various different types of loft insulation.
Blown Fiber
Because this type of insulation is blown directly into the gaps that are between the joist in the roof, it needs to be installed by a trained professional. Some of the benefits of this type include it being convenient, light, easy, and quick to install, being environmentally green, and it is ideal for use in those hard to reach places. However, it can be expensive and is not particularly effective in loft spaces that are very drafty.
Blanket / Bottom
This is the most common type of insulation, which is used in properties up and down the country. It comes in rolls and is usually made from mineral, glass, rock, or felt fiber. Because of this, it is very easy to install, it is environmentally green, and can also be used to insulate wall cavities too. However, it can cause irritation to your skin when installing, so make sure you are well covered if doing it yourself. Another downside is that the large rolls that it comes in can be difficult for use in small or restricted spaces.
Sheet
Sheet insulation is specially designed for placing on the sides of the roof that are sloping and are available in firm boards. Some come with decorative coverings on them, and some are even resistant to moisture and fire. At an additional cost, you can order it to a specific size that has been precut to fit in your loft. It is the ideal option for loft conversions and represents good value for money when you consider how thick it is. However, lots of energy is required to make this type of insulation and so it is not a very environmentally friendly product. Because of this, it is actually quite expensive.
Loose Fill
This comes in a number of different materials, including cellulose fiber, mineral wool, and cork granules. Environmentally greener options do exist that are made from recycled newspapers. Where joists are not spaced in a regular pattern, this type of insulation is easy to install. It is also good for placing on top of any existing insulation that may already be in the space. However, with it being loose, it can get blown around in those lofts that are particularly drafty. In order to install it, specialist clothing and safety equipment is required.
Having determined which type of loft insulation is best to use in your particular property, you then need to learn how to install insulation in your loft. Where you do not feel confident in doing this yourself, make sure you hire a professional.
