Are Trickle Vents Really Necessary?

So you have already invested in double glazing? But are you making sure your home is well ventilated as well as efficient?

In recent years, with the aim of reducing our bills and minimising the loss of heat, we have developed the ways in which we insulate our homes.

Whether you choose to protect against the elements with wall insulation, roof insulation, or of course double (or even triple) glazing our homes are subject to increasingly restricted ventilation.

The resulting factor is an increase in moisture in the air leading to condensation, mould, and damp. Not only does a lack of ventilation cause problems within our homes but it can also become damaging to our health as we experience an increase in humidity, allergens and other irritants.

However, rather than defeating the object of insulation by opening windows and doors to rid our homes of additional moisture, trickle vents are an ideal solution.

What Are Trickle Vents? 

We understand that thermal efficiency is extremely important but you must recognise that so is ventilation.

You may question their purpose, as many people do, after all you have already invested in insulation to rid yourselves of cold air. However, trickle vents are designed to allow air, as the name suggests, to trickle into your home at a rate that goes unnoticed without any cold draughts.

They are small openings which are integrated into your window frame to allow air into the property without compromising the effectiveness of your double glazing, or in fact the security of your home like an open window or door would.

Building Regulations States That There Should Be Adequate Ventilation in Your Home 

However, this doesn’t necessarily point directly to the use of trickle vents.

Whilst we highly recommend background ventilation, like trickle vents, which are designed to provide controlled measures of ventilation for a secure and draught free environment, there are two other types required in any building.

Purge – The removal of occasional pollutants such as smoke and the smells from cooking, or perhaps even painting and decorating, is referred to as purge ventilation whereby a simple operable window or door will suffice.

Extraction – For rooms regularly exposed to pollutants such as the kitchen, or those where excess water vapour is evident such as in your Bathroom, building regulations suggest that permanent or intermittent extraction is the answer to limiting the spread of fumes and pollutants.

If you are replacing old windows with new double glazing, it is important to note whether your original windows feature background ventilation. If this is the case then you must make sure to include trickle vents in to your new frames. On the other hand, if your old windows don’t have any form of ventilation, although feasible that they are not required by regulation, it might be worth considering hem nonetheless, especially in rooms where airflow is crucial.
