A cavity wall is essentially an external wall. For any home there are many different cavity walls, especially if they have been built after 1920. Almost every home built after 1920 has at least some type of cavity between the external portion of the wall in the interior part of the wall. If the insulation has broken down, was non-existent, or there are other problems with it, it can cost a tremendous amount of money and waste a lot of energy. That’s why the government provides grants for free cavity wall insulation.
They make these grants available to energy suppliers and also encourage these energy suppliers to make sure every home -whether it is a detached or semi-detached house, flat, or other structure- has proper cavity wall insulation to reduce carbon emissions throughout the country.
A lot of homeowners don’t even consider the prospect of getting cavity wall insulation for free. It is generally thought of as a necessary expense. Installing cavity wall insulation can cost several hundred or even thousands of pounds, depending on the house, it’s size, and accessibility.
How can you tell if your walls have cavities in them?
A cavity is any space that may need to be filled to help protect the interior portion of the home from the cold outside during the winter. It can certainly be difficult for the average homeowner to determine whether or not their external walls have cavities or are properly insulated and filled.
One way to try and determine this is increasing the temperature differential between the interior portion of the house and the outside environment. On an extremely cold night, by turning the heat up in the house and then walking throughout the house, you should be able to place your hand on the wall and feel for warm and cold spots. Every time you feel cold against the wall (to the touch) that’s usually a pretty good indicator that there is either poor insulation between the space or cavity of your external wall, it has broken down, or you have a solid external wall.
The other way is to get an energy audit. You can contact just about any energy supplier to come out to your home and inspect it to determine whether or not your external walls are efficient and properly insulated. They have equipment that can determine where draughts exist, including along the windows and those external walls. Some of the big energy suppliers in the UK are:
When you begin to notice all of the different draughts that exist around your home, the more you can understand and appreciate just how much energy is being lost every single day.
The average homeowner throughout the United Kingdom spends 55 percent of their energy expenses on their boiler. That’s 55 percent of the amount of money they pay on energy bills that is being used to run the boiler, usually in the autumn, winter, and spring months when it is cold outside. An inefficient boiler is certainly a problem, but even more so is poor or non-existent external insulation.
This is one of the main reasons why it’s so important to begin looking at various cavity wall insulation grants if you’re financially strapped or don’t have the resources at the moment to pay for insulation yourself.
The main priority of the government.
When it comes to insulation, the government has developed schemes through the years that are designed to help homeowners just like you get proper cavity wall insulation to reduce energy consumption. The primary goal of reducing energy consumption isn’t necessarily to save people money on their energy bills but to reduce carbon emissions.
Every minute a boiler is running, it’s producing carbon emissions. Even for homes that rely on electric heat, the electric supplier is generating carbon emissions for every single kilowatt hour (kWh) of consumption.
Cavity walls that don’t have proper insulation allow the cold air to press in from outside, thus cooling the air inside the house. In order to make this more understandable, think about a greenhouse.
A greenhouse is used to help grow plants, especially during the early spring months when the temperature outside is still too cold to be conducive to good growth in the open environment. When the sun’s ultraviolet radiation penetrates through the glass, it generates heat inside the greenhouse. This heat is optimal for growing those plants.
Now, instead of heat pushing through the glass and getting trapped inside, think about the cold air in a similar way pressing through the walls of your house. When that cold air pushes through, it replaces the hot air inside the house.
You might have noticed this affect if you ever had a problem with your boiler or you lost power during the winter months. You may have had a nice, warm house when the power went out or the boiler failed, but before long you began to notice the temperature dropping. Each and every hour the temperature inside your home would get lower and lower, closer to what the outside temperature happened to be.
Now, when you have electricity and a working boiler, you might not notice just how much energy you’re losing because of those draughts in your external walls. When you have empty cavities in the walls, the external cold air has a free pass into your home and replaces the warm air quickly.
There’s no reason to continue throwing money away.
With government grants for loft insulation and to fill in those cavity wall spaces, there’s no reason for any citizen throughout the UK to continue throwing money away every single month during the winter just to keep their home warm.
How do you go about getting cavity wall insulation free?
Contact any number of energy suppliers in your area and inquire about their cavity wall insulation grants. You will likely have to fill out a simple questionnaire or application to determine eligibility, but thanks to the new government scheme known as Energy Companies Obligation (ECO), it’s designed to help make sure every home throughout the United Kingdom is properly insulated, thus reducing their carbon footprint and helping protect the environment while saving money for those homeowners.
