FAQs

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 cavity wall insulation a good idea?

Cavity wall insulation is basically the process of installing an insulating material between the two layers of brick making up a cavity wall, either as a retrofit measure or at the time of building. Obviously this is not a choice if you have solid wall, but for those who do possess a cavity wall, it represents an opportunity you may not want to let slide as it is a worthwhile and affordable wall insulation option. Clearly, cavity wall insulation will make your home or property feel warmer, but it also does come with a range of other benefits which is why we’d recommend installing it. In this post, we’re going to look at a number of reasons why having a cavity wall insulation done is a good idea.

  • It’s one of the cheapest energy saving measures that’s available. Not only is cavity wall insulation really effective, but it can also deliver great saving. In other words, it possesses a bigger payback compared to other options. When compared to other types of insulation, you can’t install cavity walls insulation by yourself, however it’s not so expensive to have it installed. The cost of the insulation will be determined by a number of factors such as your location, the company hired and more.
  • It reduces your energy bills. Cavity wall insulation can save you about £100 to £200 on a yearly basis on heating bills. In other words, this is usually able to pay for itself in as little as two years.
  • It reduces your carbon carbon footprint. If your home is heated with gas or electricity like several other homes, producing that energy involves burning fossil fuels which is known to be hazardous for the environment. If the heat generated is now allowed to escape through the walls, that means you’d have to use more to keep up your required temperature. Installation of cavity wall insulation in homes will enable a more efficient usage of the energy which will ultimately cut UK’s carbon usage.
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 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.
