Insulation Installer FAQs

Is Planning Permission needed for Sound Proofing?

In general, you won’t need planning permission to install soundproofing. If you are installing soundproofing against a shared wall, you will usually need to follow the rules and restrictions set out in the Party Wall Act. In listed buildings and conservation areas, there may be extra restrictions on soundproofing.

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 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.

Does cavity wall insulation lead to damp problems?

Insulating a cavity wall should not affect the damp proofing of the wall. All insulation approved for use in cavity walls has been tested to ensure that it does not allow damp to pass through the wall. Some walls which receive a lot of wind driven rain are unsuitable for cavity wall insulation.

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 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 does cavity wall insulation work?

In recent times, more and more home and property owners are starting to come to terms with the large returns and little investment in cavity wall insulation provides. For a relatively little amount you can achieve a lot, from an increase in your home’s energy efficiency and reduction in heating bills to a huge boost in your property’s resale value and lots more. This makes you wonder how an ordinary insulation can help you achieve so much, right? Well, you’re definitely not alone! Several other potential investors are also eager to know exactly how the cavity wall insulation works to deliver all these juicy benefits. In this post, we’re going to go provide you with a detailed insight on how cavity wall insulation works. Let’s take a look!

 

Typically, cavity wall insulation works as acting as a shield which prevents the escape of heat from your home. It features a reflective surface which serves as a barrier to reflect heat from one side of the panel, effectively minimizing the amount of heat conduction that escapes through. This protection of your home from heat penetration comes with a couple of benefits with the obvious one being an incredible thermal efficiency. An insulated home or property is able to maintain a much more balanced temperature throughout the year – staying a lot cooler during the summer months and retain the heat generated during the winter months. However, a less talked about benefit is the fact that when an insulation is done during the construction of a house, the whole development phase can be completed a lot quicker. This is mainly because insulation offers total protection against weather conditions which enables internal trades to continue without the need to wait for brickwork or cladding to be completed.

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.
