The Importance of Ventilation When Having Cavity Wall Insulation Installed

Cavity wall insulation is a great way to improve the energy efficiency of your home and save money on your heating bills. It is one of the key upgrades you can apply to your home and features heavily in the government backed ECO 4 Scheme funding.

However, one crucial factor that can often get overlooked in the process is ventilation. Proper ventilation is paramount for ensuring the effectiveness and longevity of cavity wall insulation.

Confused?

If you’re confused about why you would want to ventilate your home when you’re trying to keep heat in, you’re not alone. This is why it’s so crucial.

Why is ventilation important?

Ventilation is important for a number of reasons:

  • First, it helps to prevent condensation from building up in your home. Condensation can cause a number of problems, including mould growth, which can be harmful to your health. 
  • Second, without proper ventilation, the insulation material itself can become a trap for moisture. This moisture can come from various sources such as rain penetration, condensation, or leaks. By keeping the cavity dry, ventilation helps in maintaining the optimal performance of the insulation material.
  • Third, ventilation helps to remove pollutants from the air in your home. These pollutants can come from a variety of sources, including cooking, cleaning, and smoking.

Won’t Ventilation Increase My Bills?

No. Good ventilation works hand-in-hand with insulation to improve energy efficiency. While insulation helps in retaining heat within the house during winter and keeping it cool in summer, ventilation ensures that any excess moisture is expelled from the cavity. 

This balance is essential because moisture-laden air has a higher thermal conductivity than dry air, which can reduce the insulation’s effectiveness. Thus, by keeping the cavity dry, ventilation helps in maintaining the optimal performance of the insulation material.

What are the consequences of inadequate ventilation?

If you don’t have adequate ventilation, you may experience a number of problems, including:

  • Moisture build up and mould growth
  • Poor indoor air quality
  • Increased risk of respiratory problems
  • Increased risk of structural integrity compromises

Will it cost me anything to install?

No. Ventilation is included as standard at UKEM and the cost is covered by government backed funding. 

We do not install cavity wall insulation without taking care of this crucial element, and therefore look after you, your household and your property.

How can I get cavity wall insulation installed?

If you’re interested in having cavity wall insulation installed free of charge, fully funded under the government backed ECO 4 scheme, simply complete an eligibility check on our website. It takes less than 60 seconds to complete. We will then check your eligibility and confirm back to you what measures your household qualifies for.

There is no catch and nothing to pay. There is not even any obligation to get the work done should you qualify; it’s entirely up to you. But the measures we install can save you massive amounts of money on your energy bills.

Conclusion

In summary, ventilation is a crucial part of having cavity wall insulation installed. By ensuring that your installation includes adequate ventilation, you can 

  1. prevent a number of problems and create a healthier living environment for yourself and your family. 
  2. You also protect your property integrity and ensure the insulation measures run at an optimum level.

The Form

Don't worry, many homes do not have a current EPC certificate. Let's find your address from the Royal Mail instead:

 

Your address does not have a valid EPC certificate

Don't worry, whilst your property doesn't have a current Energy Performance Certificate (EPC) we can still check your eligibility by taking some more details from you. Just click next button to proceed.

Your rating score is:

C

The lower your home's energy efficiency rating, the more money the government make available for you to improve it.

Due to the EPC rating of your property, your home's rating is unlikely to be improved by the measures we install. We are sorry that we cannot help you further in this instance.
