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.

Are there grants available for external wall insulation?

External wall insulation works to keep your home cosy and comfy while also helping to cut the energy bills. However with the great benefits also comes great costs, so it’s actually a logical decision to know whether there are grants out there which you’re eligible for to help you handle the cost of the external wall insulation.

There are grants available for external wall insulation, but rarely will you find one that covers the full installation cost. With the help of the government’s Energy Company Obligation (ECO) scheme, a couple of energy companies assist in making your home more energy efficient by offering grants or free insulation. In certain cases whereby you receive particular state benefits, you may as well qualify for a higher grant that’ll cover more of the insulation cost.

However, if your energy supplier doesn’t offer any grant, you need not worry as you can save as much on energy bill after installation. Here’s what insulation can help you save per year on energy bills:

• Floor insulation can help you save within a range of £30 to £75 each year.

• Cavity wall insulation can help you save about £85 to £280 a year.

• Loft Insulation (270mm) can help you save about £135 to £250 a year.

Generally, the amount you’ll be able to save on your energy bills depends mainly on the type and size of your property, as well as how energy efficient it already is without the insulation. In the long run, your external wall insulation will more than give you back your investment on the valuable project through your savings on energy bills. In other words, whether or not you’re eligible for a grant should never stop you from installing an external wall insulation.

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.

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 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 external wall insulation add value to your home?

The answer is yes! Houses whose external walls have been insulated are more valuable than their uninsulated counterparts. And not only does it add to the value of a home, but also significantly reduces the amount of electricity consumption. This is a major turn on for potential investors which implies a greater demand and ultimately, a higher price. The real estate market is a very dynamic one which can be hard to predict at any particular time. The frequent changes in price are usually down to factors beyond the owners’ control, but if you’re looking to put up your house for sale in the near future, it would be a wise decision to consider ways in which you can increase its value. While renovating each room can be on the expensive side, a great solution would be insulate the external walls.

An insulated house is one that is well secured against the harmful impact of extremely high or low temperature, humidity and other atmospheric factors. Hence, the reason why a house with external wall insulation has a greater value which you would not want to miss out on. What’s more? You’ll get a great thermal insulation with the top notch materials like foamed polystyrene, high quality renders, mineral wool or polyurethane.

With an external wall insulation, you know the transaction will always be favourable on both ends. You get to smile to the bank, while the buyer also gets to enjoy great value for every penny spent. To employ the services of a reliable external wall insulation expert, simply conduct an in depth research from family and friends, online and other sources. Go through their online reviews and ask questions to become more familiar with the process and its value-adding potentials.

Is external wall insulation safe?

With the numerous benefits that comes with the installation of an external wall insulation in a building, it’s also important to find out whether it’s also safe before proceeding to fit one in your home. Firstly, to ensure that external wall insulation systems are safe, they must be BBA approved, which means they’ve been subjected to a thorough testing by the British Board of Agrement and therefore, suitable for use in UK homes.

Given the fact that cladding materials have recently generated a lot of debate and negative press about how reliable some particular materials are, questions are being asked of the safety and reliability of external wall insulation. However we must clarify that, although external wall insulation can be classified under cladding, it is very different to rainscreen cladding - which caused the Grenfell fire tragedy.

External wall insulation is completely safe. However, when it comes to fire, the safety of your system depends largely on the insulation type in question. The safest type of insulation you can have installed is the Rockwool insulation boards which are rated as Euroclass A1 non-combustible. The board is specially designed in such a way that it contains fire - preventing it from reaching the other areas of the building. They also do not produce harmful emission or smoke when impacted by fire.

Meanwhile, the Wood Fibre, is also a great insulation which is known to char and not burn. Contrary to many beliefs, it actually burns slowly creating this charring effect which produces an oxygen barrier that helps reduce the spread of fire.

To make your system safer, you can also make use of Fibreglass Mesh for reinforcement. It helps to improve the strength of the tensile which promotes the security of the boards attached to the wall.

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.
