Precautions to Take When Opening Windows in Summer

Ah, the Great British Summertime. If we’re lucky, for a few days this year will we have the simple pleasure of opening our windows and letting a breeze flow through our homes. However, before you rush to lift any hatches, let’s go over some precautions to take when opening windows in summer as it may not be the most effective way to cool your home.

Unless you have the luxury of a fitted AC system in your house, you’ll have probably started to feel the effects of a heatwave this summer – especially at night. You might instinctively open the curtains and windows in an attempt to cool your home. Let’s go over some of the things you should take into consideration before doing so.

Precautions to Take When Opening Windows in Summer

Select the right time of day

When it comes to opening your windows on a hot summer’s day, timing is everything. If you have your windows open all day long then you’re only going to let the warm air in. Avoid opening your windows during the hottest parts of the day, typically the late morning to early afternoon. When things are cooler, in the morning and evenings, feel free to open your windows wide and enjoy a refreshing cool breeze.

Another tip is to utilise your blinds and curtains. If there is a direct beam of sunlight shining into a room then we suggest that you close the blind to prevent the internal temperature of your home from increasing. Additionally, if your property is fitted with air conditioning or a fan then allow that to circulate and cool the air inside your home.

Mind your allergies

If you or any of your family members have allergies, you should be cautious when opening windows. Depending on how bad a person’s symptoms get, it could have an incredibly negative impact on their quality of life. If you insist on keeping windows open this time of year then we highly recommend looking at purchasing an air purifier. Air purifiers pull in unwanted particles from the air in a specific room, such as pollen.

Secure your home against intruders

While enjoying the fresh air, you shouldn’t compromise on security. The easiest and most obvious way in is through an open window, so always close windows when you leave the house. If you are concerned about ventilation then leaving your windows locked on the latch is a secure option as well.

PVCu windows are extremely secure and extremely difficult to break into. Here at SCI Windows, we offer a wide range of styles including sliding sash, casement and tilt & turn. Our PVCu windows come with an “A” energy rating as standard; this is solely on heat retention, without bringing in solar gain. We also have “A+” ratings available if that better suits your needs.

The unpredictability of UK weather

Those that have lived in the UK for any amount of time know how unpredictable the weather can be, even in summer! We can go from clear skies to sudden rainstorms in what feels like an instant. Be prepared to close your windows quickly as mold is a common outcome.
