Insulation Installer FAQs

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.

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.

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.

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 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.

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 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.

How to get free external wall insulation?

This is a very great opportunity to not only get free external wall insulation, but also cut down your energy bills depending on the type of property you live in. Generally, to enjoy free external wall insulation you must at least be part of the group receiving one of the benefits listed below and also depends on the amount of money you earn.

Good news is, if you fit the aforementioned criteria and you’ve already installed an external wall insulation, you just may be entitled to receive a refund for the good job done.
