Many people overlook ventilation during summer. They think that winter is the time when effective ventilation is more important, and it is, but we shouldn’t ignore ventilation solutions just because the weather is nicer.

Our Air Box trickle vents give you full control over ventilation, regardless of the time of year. Let us explain the pros and cons, and why you need to fix them to your windows ASAP.

 

The Importance of Effective Ventilation in Summer

Ventilation is key to preventing a number of issues for your home or commercial building. If no fresh air is able to enter a space, the existing air becomes stale, and packed with moisture. As the room cools, this moisture is deposited, creating the perfect breeding ground for mould.

This is remedied by opening a window, but this isn’t always the best solution. If it is a large space with small windows, the fresh air won’t reach far enough. And if you close the windows overnight, or over the weekend in a commercial building, there will still be a risk of mould and damp.

In summer, this is less of an issue. The warmer nights mean that less moisture is deposited. So unless the ventilation is particularly poor, you won’t have to worry about it much until later on in the year.

However, there are some ventilation related issues that get much worse in summer.

 

Reducing Allergens with Effective Ventilation

One of the biggest, and often unnoticed, ventilation issue is airborne allergens. With your windows wide open, pollen, pet hair, and other airborne particles can freely enter the room, triggering allergic reactions or affecting people with breathing difficulties.

Ventilation is especially important in commercial buildings. With dozens or even hundreds of people working together in a shared space, ventilation is vital. In the heat of summer, you want to leave your windows open to let as much fresh air in as possible, as air conditioning and fans are less effective.

So you have to strike a balance between keeping the room cool and free from allergens. If a colleague or member of your family has severe breathing problems or allergies, you don’t want them to suffer.

To do this, trickle vents seem like the obvious solution.

 

Improving Ventilation without Opening Windows

The usual way to ventilate a room without opening windows is using trickle vents. All modern windows are fitted with them, and a lot of older properties are installing them too.

They allow a small ‘trickle’ of air to enter the space. This helps to introduce clean air, diluting the stale and humid air inside, without the need for an open window. As a result, they’re great for ventilating a room overnight, as you can keep windows securely locked. The smaller gaps also allow fewer airborne particles in, and the cleverer designs have built-in filters to catch them.

However, a trickle of air only does so much. It cannot reach far into the space, so the areas furthest from windows may still become damp or smell stale. This is especially true in commercial buildings, which often consist of large spaces and windows on only one or two walls.

In a school or similar establishment, windows can only be opened a small amount for safety reasons, which puts even more pressure on trickle vents.

Thankfully, we have exactly what you need.

 

The Genius of Air Box Trickle Vents

The Air Box is not designed to replace your trickle vents, although they have a similar design. Instead, they work alongside the permanent fixtures, essentially doubling the amount of air that can enter the space, and therefore double the amount of ventilation.

They are smarter than traditional trickle vents too. Despite being compact, they channel more air than trickle vents, pushing it further into the room. This is because the air is directed upwards instead of forwards, so it spreads out along the ceiling. As an added bonus, this means you won’t feel a draught while they’re open.

Fitting your Air Box is quick and simple, with no drilling necessary. Simply attach the device to your window frame using the clamps provided and secure them in place with a screwdriver. Instructions will be included, and we have a handy installation video if you need it.

Because of how the installation works, there will be no damage to your window frame. If you need to remove your Air Box for any reason, that can be done in a matter of minutes. But if you leave them be, they’ll work well for years without any maintenance other than a quick clean to remove built-up dust every now and then.

 

A Ventilation Solution you can Trust

We put years of time and effort into designing our Air Box trickle vents, and the benefits are plain to see. Its ergonomic design means it is extra efficient, channelling plenty of air into a domestic property or commercial building. The simplicity of installation means that you can install them on every window, taking just a few minutes each.

With an Air Box or two in place, you’ll see an immediate improvement in ventilation. Plenty of air will enter the space, but it won’t be full of allergens. This will help to keep people safe and healthy, without making them live/work in humid conditions.
