Internal Wall Insulation Grant – Your complete Guide

Adding insulation to the interior of solid walls is one means of boosting the energy efficiency of buildings. Wall insulation of this nature is known as inner wall insulation. It decreases energy expenditures, keeps the warmth inside, and makes the inside of the home more comfortable.

What is internal wall insulation grant?

The Internal Wall Insulation Grant is a government program that assists people with solid walls pay for insulation to be added to the inside of their homes. The major ways to get it are through ECO4 and the Great British Insulation Scheme. These programmes seek to make houses warmer, lower energy expenses, and limit carbon emissions. It makes insulation more accessible for low-income and fuel-poor households by paying for much or all of the installation costs.

How Internal Wall Insulation Works

The technique consists of affixing walls with insulation or insulation boards to the interior surface of the exterior walls. This creates a thermal barrier that prevents cold air from entering and heat from escaping.

Types of Internal Wall Insulation

• Insulated Plasterboards

Insulated plasterboards are boards that already have insulation on them. This makes it easy and quick to place them directly onto existing walls. They are light, don’t make as much noise, and are great for places with limited room. This choice is usually less expensive than other ones and leaves a clean finish when it is plastered and painted.

• Stud Wall System

The stud wall system calls for making a wooden or metal frame that is a little bit apart from the wall that is already there. The space between the two walls is then filled with insulation and covered with plasterboard. This strategy lets you use thicker insulation, which works better at keeping heat in. But it takes up more space inside and costs more and takes longer to put in.

• Rigid Foam Boards

PIR or phenolic boards are examples of rigid foam boards that are cut to size and attached to the inside of walls. They are very good at insulating. They are great at keeping heat in with a thin covering, so they are good for dwellings with little room. They are also a fantastic alternative for places that are often damp because they don’t let moisture in.

• Mineral Wool Insulation

Mineral wool is a flexible and breathable textile formed from spun rock or glass fibres. It is widely used in stud wall systems. It keeps heat in and noise out, which is helpful for both. It costs less and is better for the environment, but it needs greater depth than rigid boards.

• Multi-Layer Foil Insulation

There are numerous layers of reflective foil and insulation material in multi-layer foil insulation. It works by bouncing radiant heat back into the space, which makes it a good way to save electricity. It may not be as common as other approaches, but it can be helpful in small spaces or as an extra layer of insulation.

Benefits of Internal Wall Insulation

• Minimises the chance of heat loss and makes your property warm and cosy
• By enhancing the use of energy more efficiently, the heating cost must be low.
• Also prevent cold walls from moisture.
• Make the temperature constant inside your home.
• By improving its energy rating, you can enhance the property’s value.
• Reduce carbon footprints and spend your life in an eco-friendly way.

Cost of Internal Wall Insulation Grant

Depending on the materials used and the amount of work that needs to be done, the cost might range from £40 to £100 per square metre. A typical property with three bedrooms will cost anywhere between seven thousand British pounds and eight thousand British pounds. Although the initial cost is substantial, it is a worthwhile expenditure in the long run due to the savings it will generate on energy bills.

Factors Affecting Installation Costs

• Type of insulation method

Stud walls are more expensive than plaster planks.

• Material choice

The cost of foil insulation, mineral wool, and rigid foam boards varies.

• Wall condition

The cost is increased by preparation work, plaster repair, or damp treatment.

• Property size

Larger homes cost more since they need more labour and materials.

• Fixtures and fittings

Labour costs increase when radiators, outlets, and skirting boards are moved.

• Finishing work

The ultimate cost increases if plastering, painting, or remodelling are done after installation.

Internal vs External Wall Insulation

The majority of the time, internal insulation is less expensive and does not alter the appearance of the outside of the property. On the other hand, it occupies a little amount of space in the room and makes installation more difficult. External insulation is more expensive, but it preserves the space within the property and improves the appearance of the exterior.

Suitable Properties for Internal Wall Insulation

For older residences with solid walls that do not have the ability to be filled with cavities, this is the most effective method to accomplish this. It is also effective for listed or conservation properties where modifications to the outside are restricted. When compared to the use of external insulation, this is a common alternative for homeowners who are wanting to bring down their overall cost of living.

Step-by-Step Installation Process

• Wall Preparation

Make sure all surfaces are clean and moist, and take off any fittings or wallpaper.

• Taking care of insulation

Insulated plasterboards can be applied directly, or stud walls might be constructed and then filled with insulation.

• Filling up the Gaps

To avoid draughts, make sure all joints, edges, and gaps are sealed.

• Plastering and Completing

Put plasterboard over the insulation, apply plaster, and get ready to decorate.

• Redecoration

To finish off the look of the space, repaint or wallpaper the walls.

Common Materials for Insulating Internal Walls

Some of the most common parts used include rigid foam boards, mineral wool, and plasterboards with insulation. Each unit has a different level of moisture resistance, insulation, and cost-effectiveness. The finest material for you will depend on what you require and how much money you have.

Things to think about that might be bad

The extra layer makes the room a little smaller, but the insulation within works well. It may be essential to move objects such as skirting boards and sockets throughout the installation procedure, which can be bothersome. If you don’t install it correctly, you could have problems like thermal bridging or getting wet.

Saving Energy and Money

Insulating the walls of a home can save homeowners hundreds of pounds on their heating bills every year. It cuts down on energy waste by a lot, which makes homes more energy-efficient and better for the environment. The amount saved over time made up for the expense of installation.

Grants and other ways to get money

Government programs like ECO grants may be able to help with the costs of insulation for houses that meet certain requirements. Local governments may also be able to help people with money, depending on their condition and income. You might be able to afford the makeover if you look into these other options.

Maintenance and Lifespan of Internal Wall Insulation

After it has been installed, inside wall insulation requires no maintenance and will endure for decades. It remains thermally efficient over its entire lifespan with minimal maintenance requirements. Maintaining performance is easier when one routinely checks for the presence of cracks or moisture.

Common Mistakes to Avoid

Before starting the installation procedure, homeowners often don’t think about how wet the walls are, which might cause problems later on. It also takes longer to get things done if you use installers who don’t know what they’re doing or use low-quality items. To keep draughts from coming in, it’s important to make sure that all of the spaces are sealed properly.
