Ventilation
Why is ventilation such a crucial component?
Enhancing a home’s energy efficiency can result in significant cost savings, thanks to excellent features like insulation, draught-stripped windows and doors, and double glazing. Despite their advantages, they may also lessen a home’s ventilation and air permeability. This is not advised since stale air can include a lot of contaminants, including carbon dioxide.
Fresh air is essential for a home, and in most UK homes, extract ventilation fans help achieve this by providing more airflow in the kitchen and bathroom, which are frequently moist areas.
While increasing a space’s airtightness can increase energy efficiency, it may also result in inadequate ventilation, which can have major negative effects on your health. Increasing a home’s energy efficiency can result in significant cost savings. Excellent features like double-glazing, The suitability of the current ventilation should be evaluated before adding any insulation and, if necessary, upgraded.
Do I have adequate ventilation?
For the purposes of claiming funding for any insulation, a complete ventilation system shall have one of the following:
- an intermittent extract ventilation (IEV) system consisting of correctly sized extract fans in all “wet” rooms and correctly sized background ventilators (to admit “fresh” external air) in all living spaces and bedrooms
- a passive stack ventilation (PSV) system consisting of passive stack ventilators serving all “wet” rooms, and correctly sized background ventilators (to admit “fresh” external air) in all living spaces and bedrooms
- a continuous positive input ventilation (PIV) system that supplies “fresh” air, combined with correctly sized background ventilators (to allow moist `stale’ air to escape) in all living space and bedrooms
- a continuous mechanical extract ventilation (MEV) system that extracts moist, “stale” air from all “wet” rooms combined with correctly sized background ventilators (to admit “fresh” external air) in all living spaces and bedrooms
If you already have one of the above and it is deemed adequate at survey then no additional ventilation work will be required.
However, if you don’t or the existing ventilation arrangement is deemed inadequate, we will have to fit additional ventilation solutions in your property in addition to the insulation work.
In living areas not deemed “wet rooms” we will fit air-box vents to openable windows which take around 5 mins per vent to install, don’t require any drilling and are fitted from inside. No mess, no damage and totally controllable airflow in and out.
In “wet rooms” we will fit extractor fans of adequate size and design to pull “stale” moist inside air out of your property.
Applications for free well-ventilated cavity wall insulation are limited

Why should I fit them?
The first indication that the home’s microclimate is failing is condensation on the windows; higher humidity encourages the growth of mold, germs, and fungus. Typically, inadequate ventilation is the reason.
Fungi and mould can be harmful to your health. Fungal spores can cause bronchitis, allergic cough, headaches, nausea, and other uncomfortable symptoms.
Heat loss is always a problem with ventilation. Heat loss through open windows happens 10 times more quickly than it does with the Air-Box system®.
In compliance with LBN 231-15, “Heating and ventilation of residential and public buildings,” the Air-Box system® guarantees air exchange. The system fits quickly and doesn’t require cutting the window profile, which makes it really helpful.
- Noise reduction filtration of entering air to remove soot, dust, spores, and pollen.
- If normal sealing rubbers are changed with special ones, fresh air enters the channel between the frame and sash.
- The adjuster handle regulates airflow, resulting in a consistent and seamless modification of the air supply.
- The likelihood of allergic responses and other illnesses is decreased by fresh air.
