Free Insulation for Hard to Treat Cavity Wall

Cavity Wall Insulation

Put the coat to your home!

The un-insulated walls are responsible of the 35 % of the heat loss in your homes, provoking a huge squandering of energy and even more expensive bills. The un-insulated wall in UK are responsible for around the 27 % of the Carbon Dioxide Emissions.

For some houses a ‘classical’ intervention (e.g. Cavity Wall Insulation) is not suitable, because their walls are classified as ‘Hard to Treat Cavity Wall’. ‘Hard to treat’ mean walls that are not straight forward to fill because, for example, they need corrective work or have been already partially filled. People with cavity wall insulation that is defined as ‘hard to treat’ can benefit from subsidy under the Energy Company Obligation.

How does it work?

Under the ECO initiative to improve UK’s energy efficiency, the Carbon Emissions Reduction Obligation (CERO) has funding for the solid-walled homes and for the Hard to treat properties. CERO works as a non-repayable grant funding.  Anyone living in a solid-walled property is entitled to funding regardless of age, income or benefit entitlement.

3.2.2 Cavity Wall Insulation

Wall InsulationPut the coat to your home!

Un-Insulated walls are responsible of the 35% of the heat loss in your home, provoking a huge squandering of energy and even more expensive bills. The Un-Insulated wall in UK are responsible for around the 27% of the Carbon Dioxide emissions.

To solve these problems, many of our houses do not need a big intervention, but just a small precaution known as Cavity Wall Insulation.

In fact, in many houses built after 1920s there is a big chance that there is a gap or a ‘cavity’ between the external bricks and the internal walls. Cavity Wall Insulation just means that this gap will be filled with any insulation.

How does it work? Our Cavity Wall Installation team will drill little holes in your external wall, to inject the insulation into cavity from outside. It is a simple process that will take some hours and will last approximately for 20-25 years.

Cavity Wall Insulation is a simple and profitable solution. You can save up to £140 per year with a payback period under four years (even if you are not eligible for any governmental funding)[i].

3.2.3 Internal Wall Insulation

 

Put the coat to your home!

In an un-insulated home the heat loss through the walls count around the 35 %.  Above all, if your home was built before 1920s is likely to be constructed with solid brick walls without cavity. This means that is much easier for the heat to escape. There are around 7 million homes in UK built with solid wall and for them a Cavity Wall Insulation is simply not possible. Furthermore, your home could have some typical architectural features or a charm face that you would not change.

 

Internal Wall Insulation

 

 

The solutions to all these problems is an Internal Wall Insulation.

Internal Wall Insulation is done by fitting rigid boards to the wall or by building a stud wall lining filled with mineral wool insulation between. The work is finished covering it with plasterwork. Internal Wall Insulation helps your home to become warmer inside and to not alter its appearance outside.

Installing Internal Wall Insulation, allow you to save up to £460 per year and 1.8 tonnes of Carbon Dioxide emissions in Atmospheres.

Unlike the External Wall Insulation, the Internal Wall Insulation has got a cheaper price, with prices ranging from £5500 to £8500, depending of the number of the rooms to be insulated.

The thickness of the Internal Wall Insulation is around 100mm (4”) that will slightly reduce the floor area of any rooms in which it is applied.

3.2.4 External Wall Insulation

External Wall InsulationPut the coat to your home!

In an un-insulated home the heat loss through the walls count around the 35 %.  Above all, if your home was built before 1920s is likely to be constructed with solid brick walls without gaps or cavity. This means that is much easier for the heat to escape. There are around 7 million homes in UK built with solid wall and for them a Cavity Wall Insulation is simply not possible.

There are two common solutions to insulate the solid walls: the internal insulation and the external insulation.

The External Wall Insulation consist of fastening a layer of insulation material to the outer walls of your homes and then covering it with a special type of render and cladding. In this way, the walls of your home will become warmer, more weatherproof and sound resistant.

External Wall Insulation could help you to save up to £490 per year in your bills and 1.9 tons of Carbon Dioxide emissions in the atmosphere.

How is External Wall Insulation installed? First of all a survey is carried out to establish the existing wall type, required insulations thickness and render finish. Then the ‘building furniture’ (such as external pipes and fittings) are removed from the walls of your home. Next a layer of insulation material is fixed to the outer walls of your home. Finally a render is applied and the ‘building furniture’ is refitted. Now your home is ready to be warmer in winter and cooler in summer, with less energy’s use and more savings.

Even if your savings in your bills could be dramatic, the cost of the External Wall Insulation is quite expensive. Prices range between £9,400 to £13,000 per property, depending on size and access to the walls to be insulated. Nevertheless, every private family is entitled to a grant.

3.2.5 Loft Insulation

Loft Insulation

Put the hat to your home!

The 25 % of domestic heat in our homes is lost through the loft, provoking energy inefficiency, squandering of money and Carbon Dioxide emissions in the atmosphere. Putting the hat to your home, you reduce heat from escaping and you keep your home warmer through less use of energy.

With a loft insulation you can improve the energy efficiency of your home cutting down heat loss by up to 25%. With this simple Green Solution you can also help reduce your heating bill up to £180 per year[ii].

According to the Energy Saving Trust, the loft’s thickness recommended is 270mm (11”), but most of UK houses have loft insulation with only 100mm (4”). Topping up your Loft Insulation, you could save more energy, reducing the CO2 emissions by up to 730 kg, and you could save up to £180 per year, with a possible payback period as one to three years[iii].

What is a loft insulation? Loft insulation is a simple and effective process. It involves lining the space between the roof joists with either a glass mineral wool insulation rolled out in layers or alternatively by blowing a loose material directly onto the roof space to the recommended depth of 270mm.
