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.

How good is external wall insulation?

External Wall Insulation (EWI) is the act of insulating a home by fitting insulation to the exterior parts of the building which in turn improves thermal performance, cuts energy consumption ( savings on energy bill) and also adds to the home’s visual appeal. The systems are built in multiple layers, with the insulation board offering a plethora of options with each being suitable to varying projects and their needs. Installing an external wall insulation comes with a variety of benefits, let’s have a look!

• Thermal Performance Improvement

With EWI, the thermal inertia of the walls are greatly enhanced while also restricting the loss of heat. Ultimately, this lowers heating costs, enhances the comfort of indoor thermal and also reduces CO2 pollution.

• Eliminates Noise Pollution

When the noise levels are high, it can have a bad impact on our overall well being. A great way to reduce the disturbances from the outside like traffic noise is by fitting an External Wall Installation system.

• More Comfortable Living Space

Do you know the damp in homes can contribute to respiratory problems? A properly insulated home will greatly limit the impact of condensation by combating the damp issues. As a result, you can always expect your house to be cosy and comfy irrespective of the season. A cooler summer and warmer spring is guaranteed with EWI.

• Enhances The Property’s Visual Appeal

Looking for an excuse to rejuvenate your home’s aesthetic appeal? Well, you can as well try out adding an EWI system. There are a plethora of unique colours and styles you can pick from to beautify your home effortlessly.

• Adds Value To Property

An insulated home will generally cost more than an uninsulated one at the time of resale. Potential home buyers are more interested in the acquisition of a home with an EWI system due to its various benefits - and a higher demand can only imply a higher price!

does loft insulation cause condensation?

The short and simple answer to this question is yes, loft insulation does cause condensation. Over the years, problems with condensation in loft spaces have become increasingly common. While this may not be harmful in anyway, when the condensation becomes excessive it can lead to more serious issues taking root in your loft like wet rot, dry rot as well as black spot mould. Generally, the best thing to do if you’re concerned about the condensation in your loft space and that it may rapidly become a bigger problem is to get in touch with a damp specialist as soon as possible.

 

Even though insulating your loft space comes with a wide array of benefits like making the top floor rooms warmer, it’s however comes at the cost of making your loft or room space cooler. Condensation in lofts take place primarily due to the humid air making its way through insulation or other gaps into the loft space and touching a cooler surface which in turn results in beads of moisture on the timbers, lintels as well as the underside of the roof. This is why its always a great idea make use of thermal insulation with a vapour barrier that’s installed on the warmer side of the insulating material.

 

Condensation in loft is caused by excess moisture in the air and lack of adequate air ventilation. Here are some top reasons that gives rise to this in the loft:

  • Extra insulation has been installed in the loft leading to a restriction on the natural air circulation in the property.
  • When the storage boxes or other items that has been stockpiled in the loft blocks the roof vents.
  • The release of steam and moist air into the loft space by hot water tanks.
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.

Will external wall insulation stop condensation?

Damp issues on a property are usually generated by a lot of factors such as a poor or broken guttering, condensation and lots more. The question arising here is what is the possibility of External Wall Insulation (EWI) preventing condensation? Not only is EWI a reliable way to reduce condensation-caused damp, but it’s also one of the major reasons property owners in solid wall homes consider thermally rendering or cladding their external walls.

Condensation arises as a result of warm moist internal air hitting a cold surface such as the steaming up of both windows and mirror when having a shower. What happens here is the condensation of the water vapour in the air from a gas to liquid in the process of touching the cold surface - one whose temperature is significantly reduced to reach the dew point. At the dew point, condensation is very rampant, and to tackle this issue you’ll have to heighten the wall temperature in order to convert the moisture to vapour and permit it to pass through the wall. And that’s exactly the job of an external wall insulation!

To get started you must ensure that the walls are clean and dry prior to fitting the external wall insulation. The month of May through to September when the weather tends to be dry and more stable are usually the best period to carry out the project. The external wall insulation will function just like a cosy blanket around the building. Ultimately, changing the feel and temperature of the inside of your home. As a result, the previously cold walls will no longer be cold which goes a long way to mitigate the effects of condensation. Furthermore, when an EWI is installed, the rooms of your home will automatically trap more thermal mass as the heat is saved in the walls’ fabric and released back when the temperature drops.

How do I know if I have cavity wall insulation?

With cavity walls being very similar to other type of brick works, it can be quite confusing to figure out the type of wall your property possesses. If your house was constructed after the 1920s, then its highly likely the you have cavity walls, while older houses (houses before the 1920s) are likely to have solid walls. What’s more? If you happen to own a home that was built in the last decade, then it’s very possible that it was built with insulation installed during construction.

An effective way to determine whether or not your property is built with cavity wall is to examine the brickwork on your home’s exterior. The bricks will typically possess a regular pattern if it features cavity walls. In the event whereby the brick work is covered by render, you can also figure it out by taking a measurement of the wall’s width. If the brick wall is beyond 3000mm in thickness ( from the exterior wall to the interior wall), then it probably features a cavity. Meanwhile, a wall that’s narrower is very likely to be solid. Stone walls, on the other hand, may actually be thicker but are most times solid.

In a situation whereby your house is built using steel frame or timber frame, or made using pre-fabricated concrete, there are varying rules that applies when it comes to insulation and should be examined by an expert before any insulation is installed. More often than not, most contractors will have installed special air vents, which can also be a good indicator that a cavity wall insulation has been done.

How long does it take to install insulation?

How long it takes to install insulation will depend on the size of your property. In general, loft and cavity wall insulation can be installed in a day or two. External wall insulation will usually take longer to install. The rep or installer will be able to advise you when quoting for the job how long this will be.

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.
