Insulation Installer FAQs

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 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 does external solid wall insulation cost?

Before the commencement of any project, it’s always best to get an estimation of the cost. However, determining the cost of an external solid wall insulation is not the easiest of tasks as it relies on varying components such as the insulation materials to be used, labour cost and installation as well as the type of decorative finish to be incorporated. And depending on your choice of insulation material, some may need some adhesives while others may require some fixings which also contributes to the differences in price. As a result, the determination of the material cost alone can be tricky and even more so when various materials cover varying areas.

With that in mind, the cost of external solid wall insulation generally ranges between £80 to £100 per square metre2. As a result, a small flat can cost from £6000 to £9000 whereas a large detached house can have a price ranging between £21000 to £23000. To earn back your investment in terms of energy bill savings can take a couple of years, but it’s surely worth the try as there are several other benefits associated with installing an external solid wall insulation system. What’s more? Another huge factor that can influence the cost of your system is also the amount of work that’s required, how easy it is to be accessed by the installers and lots more

If you’re looking to cut down on the cost of your external solid wall insulation, then the best time for an installation might just be when you’re having another decorating or building project done such as fitting a new roof, window painting, installation of solar PV panels and more. This way, you’ll be able to spread the cost and have a greater value for each penny expended.

how to insulate a loft roof?

Insulating your loft roof comes with a wide range of benefits. Not only do you get to maintain a comfortable temperature in your house for longer, but you’ll also get to cut down on your heating bills. If you wish to insulate your loft roof, you’ve come to the right place! This process can be very tedious and time consuming especially if you don’t what you’re doing or lack the required confidence to pull it off. It’s advisable to hire the services of a reputable professional who can guarantee the best results for help and also save you some time and money that can come from potentially costly errors.

 

Before you start rolling out, you’d have to make sure that all cracks, gaps and holes in the ceiling are filled with either a standard filler or decorators caulk. You can also clean between between the gaps in the joists thoroughly. And finally, check for hazards that can cause you problems before getting stated.

  • Remember to leave ventilation gaps as you start from the eaves. Then work towards the loft’s centre, starting from the point furthest from the hatch.
  • Lay the first layer between the joists which should be 100 mm and then the subsequent layer should be 170 mm to make it up to the recommended 270 mm.
  • Carry the electric cables above the insulation and work around visible light fittings.
  • Cut the roll in the centre of the floor when rolling out from the eaves on both sides with the help of a craft knife. Ensure that there are no gaps between the insulation and the joists’ edges.
  • Lag pipes as you go in order to prevent walking over the insulation to get back to them.
  • Ensure that the loft is totally insulated
  • Insulate the hatch.
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 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 does loft insulation work?

A lot of an uninsulated property’s heat is lost through the roof and that’s even more alarming, when you realize this figure is up to a quarter of the total heat of the house. Hence, the tremendous importance of preventing this heat loss through loft insulation which will go a long way to help you against spending unnecessary thousands of pounds on heating bill as well as energy loss.

 

Loft insulation is an effective method to achieve the desired result, however the question is, how exactly does it work? Well, it’s time to find out!

 

Using either a fireplace or central heating to heat up your home, a large quantity of that heat would be lost through the roof of your home. Generally, heat rises and when it does, there’s simply no way to prevent it - it’s just science. Escaping by both the conduction and convection methods via your roof, the heat escaping through your ceiling, into the loft space and out into the open air outside can only be significantly reduced by laying loft insulation.

 

Generally, the added layer of insulation works by trapping the heat inside the room below the loft so as to enable the air within your house to stay warmer for longer. What’s more? The layer of insulation also keeps cold air from the outside from entering your home. As a result, you don’t have to heat your home as much in order to achieve the same temperature for each individual room. Over time, just by doing this you can potentially save hundreds pounds. Getting it installed in your home may actually seem a bit expensive at first, but it’s something that’ll eventually pay off.

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.
