One of the most cost-effective and hassle-free options for insulating your property is cavity wall insulation. But is it right for you and your home? Here we answer all your questions about this efficient method to save money whilst keeping your home cosy.
Benefits of Cavity Wall Insulation:
- Improved Energy Efficiency: cavity wall insulation reduces heat loss through the walls, helping to maintain a comfortable indoor temperature, which can lead to lower energy bills and lower energy consumption.
- Quick Installation: cavity wall insulation can often be installed relatively quickly and with minimal disruption to your home. The process typically involves drilling small holes in the exterior walls and injecting the insulation material, which is then sealed.
- Condensation Prevention: insulated walls are less prone to condensation issues, which can lead to the appearance of mould. Cavity wall insulation helps to maintain a drier and healthier indoor environment.
- Sound Insulation: While primarily designed for thermal insulation, cavity wall insulation can also provide some level of soundproofing, reducing the transmission of noise from the outside or between rooms.
- Increased Thermal Comfort: insulated walls help maintain a more consistent indoor temperature, reducing cold spots and drafts. This results in improved thermal comfort and a more pleasant living environment.
Frequently Asked Questions
IS CAVITY WALL INSULATION SUITABLE FOR MY HOME?
Cavity wall insulation is not suitable for all property types. If your home is made with solid walls, which don’t have a cavity, or the condition of the walls are in poor condition, including cracks in the external finish, or existing dampness, then this type of insulation may not be suitable. However, if your home was built after the 1930, there’s a good chance it will have cavity walls and will therefore be suitable. To find out more, fill in our contact form and one of our surveyors can arrange a survey at your home.
HOW IS CAVITY WALL INSULATION INSTALLED?
Cavity wall insulation is installed by drilling 22mm holes at intervals of approximately every 1 metre on the outside walls of your home. Insulation material is then injected into the cavity through these holes, which are then sealed up by using cement. The insulation material used is usually polystyrene bead, which provides excellent thermal benefits for your property, helping you stay warm in the winter and cool in the summer.
WHAT IF I LIVE IN A SEMI-DETACHED HOUSE?
If you live in a semi-detached property, and your neighbour does not want cavity wall insulation, or their property is not suitable for the insulation, the insulation technician will insert a cavity barrier brush into the cavity wall, which helps prevent the passage of insulation beads between the attached properties. The barrier brush also prevents the movement of any debris, dirt, or even pests, providing additional benefits.
HOW MUCH CAN I SAVE BY INSTALLING CAVITY WALL INSULATION?
The amount of money you will save on your energy bills will depend on the type of property you live in; a large, detached property will generally save significantly more than a flat, due to the amount of walls being insulated and the size of living space. The Energy Saving Trust states that a detached property can save as much as £455 per year on energy bills, whereas a Mid-flooor flat can save up to £125. And as energy bills increase, you can expect to save even more!
ARE CAVITY WALL INSULATION GRANTS AVAILABLE?
Zing Energy are currently helping householders to see if they qualify for free cavity wall insulation via several energy grant schemes. These energy grants can cover the full cost of installation, carried out by our professional cavity wall insulation technicians. Currently the Government-backed Energy Companies Obligation (ECO4) scheme, which runs until 2026, is designed to help low-income households who are in receipt of benefits, gain access to energy saving grants. Contact Zing Energy today and we can help guide you through the qualifying process.
WHAT HAPPENS IF MY CAVITY WALLS ARE BLOCKED?
Prior to the installation of cavity wall insulation, Zing Energy will carry out an in-depth property assessment, to check the conditions of the cavities, and to see if your home has any obstructions. If any remedial works are required, including replacing corroded wall ties, removing rubble and installing cavity brushes, our installation teams will make good in preparation for the cavity wall insulation.
