Cavity wall insulation is a popular construction method that can significantly reduce heat loss and help create more energy-efficient properties. However, new build cavity wall regulations are placing greater emphasis on the U-value of insulation, meaning that a higher standard needs to be met. This article explores the evolution of this regulation and discusses how it can be navigated.
Building Regulations and Approved Document L dictate that all newly built homes must meet a minimum standard of insulation. This includes the use of insulation in the walls, roof, and lofts. While achieving these standards may seem daunting, a qualified expert can offer insights that are tailored to your specific project and help you achieve compliance.
Whether you are building a home or commercial property, meeting new build cavity wall insulation regulations is crucial to the success of your project. This will help you make the most of your investment and create a more sustainable living space. Here are a few things to remember:
The Right Type of Insulation
Before installing insulation, it is essential to consider the location, property type and age, climate, and exposure to external elements of your property. This will determine if your property is suitable for cavity wall insulation, as well as the most appropriate type of insulation for your site. The best option is full fill, which involves filling the entire cavity with insulating material, giving the most efficient result. Partial fill is also available, which only insulates a portion of the cavity, allowing ventilation and preventing dampness.
When looking for a professional to carry out the work, look for an installer who is registered with CIGA or the National Insulation Association (NIA). This way, you can be sure they are fully trained and qualified to perform the job correctly. Also, it will give you peace of mind that the company is fully insured and backed by a guarantee should anything go wrong with the installation.
You should always ensure that your existing wall structure is in good condition before insulating it. Cracked or damp walls can affect the performance of your insulation and lead to costly repairs. Also, you should check for defects like faulty window seals, leaking gutters, and damp patches inside the walls, which could cause damage to your new wall insulation.
A reputable installer will be able to assess your property and recommend the best method of insulation for you. They will also know how to choose the correct materials and check that they are compatible with your existing wall structure. They will also be able to identify any dampness issues and rectify them, so that you don’t have to face expensive repair bills.
