The kinds of roofing insulation offered rely on the sort of roof covering that it will certainly be utilized with. With a pitched roofing, either cozy or chilly loft space insulation can be appropriate. Cold loft insulation is the most affordable choice, merely involving putting insulation over wood joists. Nonetheless, as this only stops heat getting away the living area of the home, it isn't appropriate for those seeking to concealed the loft right into a living space.

It's typically the most inexpensive option and great all-purpose insulation, particularly for in between joists. It's the easiest kind to fit yet isn't suitable for the roof.

 

Loose-fill Insulation

This sort of insulation includes a loosened, lightweight, product, such as cork granules, cellulose fibre, mineral woollen or perhaps recycled newspaper. It can be utilized to top up existing insulation or by itself. The main drawback is it isn't very protected as well as can be really untidy!

Blown-fibre Insulation

Loosened materials of various kinds blown in between joists, this is excellent for hard-to-get-at locations but doesn't offer a complete option, especially in a draughty loft space. It's likewise pricey and needs to be mounted by a expert.

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.

how much loft insulation do I need?

Over the years, more and more home and property owners are beginning to realize the huge benefits that can be derived from loft insulation being a worthwhile investment. It’s quite worrisome the way in which energy bills have soared over the past 10 years and loft insulation is a considerable affordable energy efficiency measure that can go a long way to help increase your home’s energy savings.

 

As far back as the 1980’s, the standard when it comes to insulation thickness was 25 mm to 50 mm which was, at the time, considered to be sufficient. However, building regulations have changed the norm that now states that a new build needs to possess 270 mm of insulation in the loft in order to achieve the required u-value of less than 0.16/m2k based on the standard rock wool or sheep wool insulation.

 

Generally with loft insulation, there’s a law of depreciating returns which implies that the first couple of insulation centimetres will save you many times the cost of the installation, however an extra layer or centimetre is going to add less value to the point where it’ll no longer be wise or worthwhile to add any further centimetre. Therefore, with cheaper energy prices 30 years back, that additional couple of centimetres was not just worthwhile, but with the recent alarming rises in costs of fuel, that additional £10 savings per year has all of sudden changed to £30 which makes it become a lot more attractive.

 

If you already have 270 mm of loft insulation, regardless of the material you’re looking to add you’re most likely not going to benefit from a top up. The cost of the materials and installation will definitely be too high for the couple of pounds it’ll save you per year.

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.

Is loft insulation flammable?

When thinking about the right insulation material for your loft, some of the first few things that comes to mind is the various properties of that material as well as how good they fit with your home’s needs.naturally, you’d like to ensure that the insulation will be efficient enough to add to the overall energy efficiency of your home, however there are also other features that may not get as much attention but also happens to be equally important. As the primary function of an insulation is to blanket your house to offer a barrier against heat loss, going for an insulation material that’s also fireproof is crucial as loft insulation can burn. Although most insulation materials are fireproof, a myriad of problems can actually make your insulation burn.

 

For instance, fibreglass insulation is produced using glass combined with plastic polymers and is naturally resistant to fire. However, even at that you’d have to be careful with batts that are supported with foil or paper due to the fact that these materials can burn pretty quickly. Cellulose, on the other hand, is not fireproof and is required to be treated by other flame retardants in order to help reduce combustion. Some of the best insulation materials that are resistant to fire includes the following:

  • Fibre glass. This is made of glass that’s spun into fibres, then combined using plastic polymers. As a result, fiberglass insulation is naturally resistant to fire.
  • Mineral wool. Having a high melting temperature, this insulation material happens to be a great fit for thermal applications due to its superior fire resistant properties. In fact, mineral wool is still naturally non-combustible even if composed of recycled iron and steel by-products, or from actual mineral rock itself.
