Insulation

Cavity wall insulation

Around 35% of all heat loss occurs through the walls of your home. However, a fully insulated cavity can save an average household up to £210 a year*.

There a multiple type of blown cavity wall insulation available in the UK. Our partners install some of the highest performing products available which reduce the risk of condensation and provide the maximum amount of potential savings. We recommend ‘Bonded Bead Insulation’ is an oil-based, waterproof product which is injected within the cavity walls and bonded with a glue to form a solid structure however allows water to pass through it into your homes damp proof course. Following the installation of Cavity Wall Insulation, you will be issued with a 25 year insurance backed guarantee

Cavity Wall insulation extraction

Unfortunately, due to a combination of factors including rogue installers, there are many properties in the UK that have cavity wall insulation installed that were unsuitable for the measure. This has led to a number of problems across the country, including damp and condensation.

Thankfully injected insulation can be extracted from within cavities and replaced with Bonded Bead Insulation providing that the property is suitable.

Problem

Wind and driving rain against exposed brickwork can damage bricks, or more commonly, the pointing, allowing water through the wall and into the cavity. Some of the materials used in the past, particularly anything fibre-based, can absorb and hold this water, allowing it to cross the cavity to the inner walls of the home, causing damp problems. In addition, if a property does not have a Damp Proof Course (DPC) cavity wall insulation is not suitable. Coastal areas are the most effected

Solution

Extracting the cavity wall insulation is a quick, clean process, completed from the outside of the property. Compressed air is blown into the wall through drill holes, and the insulation is removed via strategically removed bricks at the bottom of the wall. Once the process is completed, the brickwork is repaired and Bonded Bead Insulation is reinstalled into the property. For properties / walls that are highly exposed products such as ThermiDry can be applied to the external wall which provides a waterproof barrier to stop driving rain penetrating through the walls into the cavities whilst still allowing the cavity to breathe.

Solid wall insulation

For homes where cavity wall insulation is not an option, solid wall insulation is another viable solution.
There are two types of wall insulation; external and internal.

External wall insulation

A system of insulation boards and render is applied to the outer walls, refreshing the look of the property and improving the insulation and draught-proofing properties internally as well.

Internal wall insulation

Perfect for those who are unable to alter the outside of their house for any reason (for example the building is listed, or the house is in a conservation area and unable to get planning permission), internal wall insulation applies a system onto the internal walls on a room by room basis, creating a dry-lined, insulated internal wall. All fixtures and fittings are put back as new, with the new wall taking around 10cm of space from the existing wall.

Loft insulation

Around 25% of heat escapes through the roof and according to the Energy Saving Trust, a typical detached house could save up to £215 by installing loft insulation. It is one of the quickest and easiest ways to make your home more energy efficiency. Although most homes have some form of insulation, not all have the correct amount.

Room in roof

Around 25% of all the heat is lost through loft rooms without insulation. Adequate insulation could save you up to £400* per year.

If you have a Room-in-Roof or Loft Room it may not be properly insulated, especially if it is an older property. 

A Room-in-Roof is defined by having a permanent, fixed staircase to your loft room which is heated and has a window. Roof rooms are often difficult to keep warm in the winter and can get uncomfortably hot in the summer.

Room-in-Roof insulation is for dedicated loft rooms – not boarded storage spaces. It is a combination of measures, ensuring that all ceilings, eaves and sloping rooves are correctly insulated.

Cavity Wall Insulation (CWI)

What is it:

Around 35% of all heat loss occurs through the walls of your home and insulation is recommended as a primary way to save money a Cavity Wall Insulation is a method of retaining warmth in properties who have a wall structure made up of two separate walls with a space between them, this is known as a Cavity Wall. There a multiple type of blown cavity wall insulation available in the UK. If a property has not had a Damp Proof Course (DPC) this measure is unsuitable.

Savings

  • Tip: If your property has cavity walls you will usually see an even pattern with bricks lying sideways.

Problem

  • Unfortunately, due to poor fitting and poor choice of materials some cavity wall insulation has been the source of problems such as mould and damp as rain water hitting outer walls has been absorbed by insulation fibres and then carried through to internal walls.

Solution

  • Warmer Communities partners install some of the highest performing products available, reducing the risks of such problems whilst maximising potential savings by using materials such as ‘Bonded Bead Insulation’. This oil-based, waterproof product which is injected within the cavity walls and bonded with a glue to form a solid structure however allows water to pass through it into your homes damp proof course. Following the installation of Cavity Wall Insulation, you will be issued with a 25-year insurance backed guarantee

Cavity Wall Extraction

Cavity wall insulation can be extracted and replaced with a new type of insulation material such as Bonded Bead Insulation, providing that the property is suitable. Extracting cavity wall insulation is a quick, clean process which is completed from the outside of the property.

How?

The process involves blowing compressed air into the cavity wall through drill holes before bricks are removed and the insulation is strategically removed.

The brickwork is then replaced, and Bonded Bead Insulation is installed into the property.

For properties with walls that are susceptible to weather damage, products such as ThermaDri can prevent rain soaking into walls as it provides a waterproof barrier whilst (importantly) allowing the cavity material to breathe.

Solid Wall Insulation (SWI)

What is it:

For homes where cavity wall insulation is not an option, solid wall insulation provides a solution, creating a warmer and more energy-efficient home.

There are two types of Solid Wall Insulation; external and internal.

Savings

  • Tip: If your property has a solid wall, bricks are usually alternating with brick laying patterns that are inconsistent.

External Wall Insulation (EWI)

  • A system of insulation boards and render is applied to outer walls, refreshing the look of the property and improving the insulation and draft-proofing properties as well.

Internal Wall Insulation (IWI)

  • Not all buildings can have external alteration due to restrictions, but Internal Wall Insulation is an excellent solution to optimise energy efficiency in such properties. Buildings which are listed or located in areas of conservation can still improve heating at home through the application of this system.

How

  • The application of a special system creates dry-lined internal walls, improving insulation. This is carried out on a room by room basis, reducing internal space by around 10cm but creating a more energy efficient space.

Loft insulation

What is it:

Around 25% of heat escapes through the roof and according to the Energy Saving Trust, a typical detached house could save up to £215* by installing loft insulation. It is effective for at least 40 years and is one of the quickest and easiest ways to make your home more energy efficient.

Problem

  • Amongst homes that have some form of insulation, not all have the correct amount.

Solution

  • Warmer Communities partners use quality Euroclass A1, non-combustible Glass Mineral Wool to insulate your loft space creating a warmer, more energy-efficient home which will save you money.

Did you know?

  • Loft insulation pays for itself in the amount of money you save.

Room-in-Roof

What is it:

Around 25% of all the heat is lost in an un-insulated room in the roof.

Did you know?

  • You could save up to £400* a year on your fuel bills through adequate insulation of your room-in-roof.

Problem

  • A Room-in-Roof is defined by having a permanent, fixed stair case to a loft room which is heated and has a window. Roof or loft rooms are often difficult to keep warm in the winter and can get uncomfortably hot in the summer and it may not be properly insulated, especially if it is an older property.

Solution

  • Warmer Communities trusted installers carry out Room-in-Roof insulation through a combination of measures ensuring correct ventilation and that all ceilings, eaves, and sloping rooves are insulated properly.
