A simple tweak may help improve summer cooling ventilation and make a noticeable difference to how cool your home feels
Experts suggest that your windows could be contributing to heat accumulating inside your home, and a straightforward adjustment could make a significant difference. Window specialists Express Bi-Folding Doors have disclosed how a clever, little-known mechanism can help keep homes cooler during hot spells, along with other ways to get your windows working harder for you this summer.
Many modern windows feature a small built-in adjustment screw that controls how snugly the window sits against its frame. While pulling the window closer to the frame helps retain heat during winter, loosening it slightly in summer allows for improved airflow and ventilation when you need it most.
To switch to summer mode, open your window and locate the small adjustment screws on the inside of the frame. These typically require an Allen key and will have a notch currently positioned at around 3 o’clock if you have already applied the winter setting.
Turn the screw anti-clockwise by a quarter turn so the notch moves back to 12 o’clock. This releases the window slightly from the frame, permitting air to circulate more freely when the window is open or on its vent setting.
This minor adjustment can make a noticeable difference to airflow throughout your home, particularly overnight when you want to allow cooler air to circulate without fully opening your windows, reports Kent Live.
Use your windows to create a cross breeze
One of the most effective ways to cool a home naturally is through cross ventilation. Open windows on opposite sides of your home to create a through-breeze, ideally in the morning before temperatures peak, and again in the evening once the outside air begins to cool.
If you have bi-folding or sliding doors, throwing these open alongside a window at the far end of your home can substantially boost airflow, transforming your living space into a far more comfortable setting.
Block out direct sunlight during the hottest part of the day
Between roughly 11am and 3pm the sun is at its most intense, and direct sunlight streaming through windows can heat a room rapidly. Drawing blinds or curtains on south and west-facing windows during these hours can considerably lower the indoor temperature.
Thermal curtains, typically associated with retaining warmth throughout winter, actually work in both directions — their thickness also serves to block solar heat gain during the summer months.
Check your window seals are not trapping stale warm air
If your windows are failing to open or ventilate correctly due to worn or stiff mechanisms, it is worth giving them a thorough inspection. Clean the tracks and hinges, and ensure that ventilation features such as trickle vents are unobstructed and functioning properly, so you can make the most of even the faintest breeze.
Consider window film for south-facing rooms
Solar control window film can be an affordable solution for south-facing rooms that receive a great deal of sunlight. In contrast to ordinary window film, solar film is specifically engineered to deflect heat away from the glass before it penetrates the room, assisting in maintaining cooler temperatures while still allowing natural light to filter through.
