How to Find the Best Cavity Wall Insulation Installer

Cavity Wall Insulation is a fantastic way to keep you home warm and costs down however, it is important to find the right installer to get the job done properly. Eco Home Insulation are a fully qualified PAS 2030 standard and gas safe registered company working in compliance with British Building Standards. Our company delivers grant funded measures to a wide customer base via an expansive range of energy efficient methods to directly reduce your energy bills and carbon footprint. 

Our role involves checking your eligibility for funding, sending our trusted surveyors out to your home to see what measures are required, accessing the funding from the Government for these measures on your behalf, installing the necessary products and helping with any maintenance needed after.

Cavity Wall Insulation

There are many different types of insulation that are used within construction. Depending on the type, location and age of your property different methods will be applied, which are all predetermined by a surveyor. The Energy Companies Obligation (ECO) scheme incorporates 3 main types of insulation within its funding including loft, cavity wall and internal wall.

Most homes that were developed between 1920 – 1990 will have a gap between the internal and external walls of the property, known as a ‘cavity’. When this gap is filled with an insulating material, it ensures that the house is well insulated, meaning the warm air is kept in and the cold air is kept out. 

Cavity wall insulation also reduces the speed at which warm air can escape from your property and in doing so means you won’t need to heat your home as regularly – saving you money! The Energy Saving Trust (EST) states that having your cavity walls insulated as opposed to uninsulated, can save you more than £280 per year on your heating costs.

However, not all homes are suitable for this type of insulation. Timber framed, metal clad, and stone properties do not typically require this type of insulation due to their lack of ‘cavity’ within the walls. It is also noted that if the walls within your home suffer from ‘cold wall syndrome’ [damp or cold walls within the interior of your home] then this issue will need to be addressed before the cavity wall insulation is installed. The external wall of your property needs to be in good order before we start this process, and we will of course advise should there be any issues impending the install.

How does it work?

If your property is deemed to be conventionally constructed (most properties post, but not limited to, 1920’s onwards) it is likely to have a cavity (gap/void) between the external and internal walls. 

We use the Therma-bead system, which consists of the polystyrene beads being injected into the cavity wall via our unique injection gun into a small hole in either the external or internal skin of the property. As the beads are pumped in, they are mixed with a binding agent forming a homogenous mass that fills the cavity void in its entirety, resulting in a protective barrier that gives permanent reduction in the heat loss to your home.

All cavity wall insulation installs will benefit from a retrofit assessment, along with additional checks being sent to a chartered surveyor first – who will assess the property type prior to install. This pre-check takes things like the property construction, wall thickness and property location into consideration.

There are many factors which can affect the viability of cavity wall insulation and the insulation will not be installed unless the property meets all the necessary requirements. Upon completion, you will be issued with a 25 year, independent backed, quality assurance guarantee. If we were to ever cease trading, your guarantee will still be in effect.

Is Cavity Wall Insulation the best option for my home? 

Before looking into having Cavity Wall Insulation installed to your home, you first need to identify whether it is the right option for you. C.W.I is best suited to properties that have an uninsulated cavity between the internal and external walls. However, if your home has C.W.I within the walls it is worth checking to see if you have an existing guarantee and that the current insulation is of a sufficient standard. If this C.W.I isn’t sufficient then you may want to consider Cavity Wall Extraction and Installation. 

If you are unsure of how to check any existing C.W.I or do not know whether your property benefits from C.W.I it may be worth asking a trusted fitter to come and survey your property who will; be able to advise you on the best options. 

We at Eco Home Insulation are UK registered and experienced installers of Cavity Wall Insulation. 

How much does Cavity Wall Insulation cost? 

The cost of Cavity Wall Insulation will typically vary from home to home, depending on the size and age of the property and the type of insulation used. However, The Energy Saving Trust states that regardless of your home type, you should recover the costs of installation within 5 years or less due to the money saved on your energy bills. 

Below is a table displaying the estimated average costs of installation, how much you could save on your energy bills and how many kilograms of CO2 emission you could save per annum with C.W.I:

How long will the installation take?

Cavity Wall Installation can typically be installed within a day, and you can expect the process to be fairly quick and hassle free. You are not required to leave your home whilst the installation is completed as most of the work constructed is outside of the property. 

However, there can always be complications with any construction so please bare this in mind.
