The types of roof insulation available depend on the kind of roof covering that it will be used with. With a pitched roof, either cozy or cool loft insulation can be suitable. Cold loft space insulation is the most inexpensive alternative, just entailing putting insulation beyond wooden joists. Nonetheless, as this only stops warm leaving the living location of the residence, it isn't suitable for those seeking to hidden the loft into a home. Cozy loft insulation is placed straight under the roof, and also hence will maintain the loft room at a consistent temperature over the program of the year. Thus, it is excellent if the loft is utilized as a space. Cozy loft insulation can be found in various forms, be it glass-wool or polystyrene. Spray foams can also be used, yet in some situations might be inappropriate.

 

Kinds of loft space insulation

Blanket Insulation

One of the most common type of loft space insulation, this can be found in rolls of rock, glass or mineral fiber (we utilize Earthwool by Knauf which is a really excellent environmentally friendly option), or else foil-backed felt. It's usually the least expensive option as well as good all-purpose insulation, particularly for in between joists. It's the simplest type to fit yet isn't suitable for the roof.

 

Loose-fill Insulation

This sort of insulation consists of a loosened, lightweight, product, such as cork granules, cellulose fiber, mineral woollen or perhaps recycled newspaper. It can be made use of to cover up existing insulation or by itself. The main downside is it isn't really safe as well as can be really untidy!

 

Sheet Insulation

Firm boards of either artificial or all-natural materials, this is the best option for protecting the underside of your roofing. The boards offer extremely reliable insulation for your loft room as well as can also be embellished over. The disadvantage is that sheet insulation often tends to be one of the most pricey type.

 

Blown-fibre Insulation

Loosened materials of different kinds blown in between joists, this is ideal for hard-to-get-at places but does not provide a full service, specifically in a draughty loft space. It's also costly and needs to be installed by a specialist.

FAQs

how much is loft insulation?

More often than not, several homeowners fail to realize there’s so much value sitting right under their roof - the loft. When a loft is insulated, there are so many juicy benefits that can be derived. It can go a long way to save increase you energy savings and several more functions. Therefore, if you really wish to maximize the space under your home’s roof, you’d have to considering insulating it. So how much would it cost to have your loft insulated? Here, you’ll discover the cost of insulating your lofts so you that you can set a budget and start to plan.

 

The cost of insulating a loft is actually affordable for several individuals, however, this depends on a wide range of factors such as the size of the house as well as the type of insulation being installed. One significant factor is the insulating material that you choose to install. If done properly, you’d be able to prevent heat from escaping through the roof of the house which helps improve energy efficiency and ultimately, save you some money on heating bills.

 

If you’d prefer to make it a DIY project and you go for a blanket insulation it costs about £5 per m2. therefore, this will cost within the range of £100 to about £150 for a small home.

 

For a professional service, you’ll be provided with a quote for both the materials and labour. The amount will be based on the number of insulation required, the company hired, your location as well as the method selected. The price to purchase and install blanket insulation  would be between the range of £300 to £400 depending on the size of your home.

Will insulation save me money on my energy bills?

This depends on the amount of insulation already present in your property. However, adding insulation has been proven to improve the energy efficiency of your home and decrease your heating bills, this is more obvious in older properties or where single glazing is still in situ.

how thick should loft insulation be?

Over the years there has been an increase in the recommended thickness of loft insulation by the government. Obviously, the reason behind this is pretty simply - the thicker the layer of your loft insulation the bigger your savings. The UK government is very keen to every house in the country to have loft insulation fitted where possible as it helps to minimize the heating demands of these properties. Households get to benefit from loft insulation in so many ways which includes reduced energy energy bills as well as having a home that stays at a more comfortable temperature for longer.

 

Generally, for the government energy efficiency is crucial as it implies that the highest demand ( which is usually the time of the day when gas or electricity use is at its peak ) reduces, since each building requires slightly less energy. Overall, that ultimately implies that new power plants don’t have to be built which is some nice cost savings for the government.

 

In the 1980’s, any thickness of loft insulation from 25 mm to 50 mm was considered the standard. But then, building regulations stated that homes should have as much as 100 mm of loft insulation. Over time, this gradually increased to 270mm for new builds and also recommended for other properties, although not essential. As a result of this, there’s always a need to check how much insulation you currently have in your loft before you decide to purchase more. You may discover that you already have something within the range of 20 mm to 200 mm up there and knowing this and the insulation values will assist in determining how much more you’ll need to purchase, if any at all. You should also note that some modern materials can offer the same thermal insulation whilst not being as thick.

what is the best loft insulation?

If you have a loft, then the next thing that’s crucial is a loft insulation. Asides from cutting down on your carbon footprint, when you’re able to install an effective loft insulation you can slash your heating bills by up to £250 per year. What’s more? Besides making your home more energy efficient, it can also increase the value of your property a great deal. So if you’re also considering the insulation of your loft, one of the few things that comes to mind is, what loft insulation is the best to incorporate? In order to help you make the best informed decision possible, this post is going to address this issue and put you on the right path.

 

In truth, there’s no way to say exactly which type of insulation is the best as all types usually have a different purpose as well as usage. The insulation you choose for your home’s loft is be based largely on the how you’re going to make use of the space as well as any unique challenges you might face given the shape of your home’s loft. Below are some types of insulation to give you a better idea:

  • Blanket insulation. This is the most common type that comes in rolls of rock, glass or mineral fibre ( or foil-backed felt ). It normally the most affordable and also a good all-purpose insulation which is easy to fit although not suitable for the roof.
  • Loose-fill insulation. This type of insulation features a loose, lightweight material such as cork granules, cellulose fibre, mineral wool etc. It can either be incorporated as a top up or on its own. The primary drawback is it isn’t very secure and can also be very messy.
  • Sheet insulation. This is the best solution for the roof’s underside as it offers a highly effective insulation for your loft space and can also be decorated over. The drawback here is that it’s usually the most expensive type to purchase and install.
