The fact is, the winter months mean our homes are less ventilated, and we spend more time in them and we often dry our clothes indoors. These small and unobtrusive window and door enhancements provide genuine benefits in providing controlled ventilation and fresh air into the rooms we use every day and those we don’t. Allowing air to circulate from the outside to inside a building displaces moisture from the internal air. Over the past few decades, considerable advancements have been made in the art of draught-exclusion. Modern windows are airtight, which is great – in terms of energy efficiency.

At Everest, Energy Efficiency Is at the Core of What We Do

Thermal comfort, energy-saving, and reducing heat loss mean better all-round comfort. However, it also means better-sealed homes resulting in the air unable to escape and of poorer quality inside the room. This poor-quality air comes in several forms. CO2, candles, paint fumes, cooking and bathing and those rarely opening windows in their homes. All this adds to moisture, stale air, and having to deal with condensation.

Ventilation in buildings is critical to maintaining healthy living spaces. As windows and doors are considerably more draught-proof, and buildings become more energy efficient, natural ventilation from outside fresh air is reduced.This is set by Hotjar to identify a new user’s first session.

It’s not an alternative solution to having a Building Regulations requirement for ventilators in window. Without good ventilation, there will be more substances in the air that can cause harm to people. This includes pollutants from cooking, cleaning products, hygiene products and fabric furnishings. Diluting pollutants generated inside the home using ventilation is necessary, but importantly, outdoor air quality effects indoor air quality. There is also a high risk of mould in homes which are poorly ventilated. We do get asked how to cure damp and mould around windows and the first question we ask is "what ventilation do you have in the room , read more below on how why it happens and your route to ventilation Some windows do have a night latch and can be securely left open with a small gap. But it’s worth noting that a night latch is not an acceptable ventilation option for building regulations (see above).
