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 to insulate a loft?

Do you know about 25 percent of heat that escapes from an uninsulated house are lost through the roof? Fortunately, roof insulation is something that can done by all DIYers irrespective of their experience levels. However, if you happen to lack the confidence necessary to pull off this, then it’s strongly recommended that you hire the services of a professional who can guarantee the best results and also save you time and money that could arise from potential cost mistakes. Let’s take a look!

  • Clear out all clutter. This involves taking out all the rubbish and clutter from the loft. In order to work effectively, you’ll need a totally clear and empty loft space.
  • Ensure that there’s sufficient insulation. The importance of a good ventilation cannot be overstated. Poor ventilation will result in forming of condensation and this condensation can make the roof timbers rot and compromise the structural integrity of the entire roof. If there are no roof windows which is the easiest way to provide a loft ventilation, the next best option would be to follow the loft floor along to the point where the roof comes down to meet it. There should be a gap at this point, also referred to as the eaves, between the outside wall and the underside of the roof.
  • Measure your loft area. Take a measurement of the loft space in order to calculate the amount of insulation as well as the type you need. If you’re not sure, always get more that it’s required as skimming on the amount you use will only back fire in form of increased energy costs
  • Check for water pipes.

 

To get started, simply make sure all cracks and gaps in the ceiling are filled using a standard filler or decorator caulk. Once done, clean the gaps in the joists and even to the point of hovering all the dust up. Finally,check for the hazards that can cause you problems before laying the loft insulation.

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.
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.

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.
