How to stay cool as temperature in the south are due to hit 35 today and even 20 tonight!
Well if they are sash and not painted shut, try opening them!
I know that sounds flippant but it is a well known fact that sash windows, having an opening both top and bottom of the window, encourages free air conditioning. Because hot air rises, so it can escape at ceiling level, allowing cooler air to drop to the floor, in turn pushing more hot air towards the ceiling. Remarkably, most double glazing being fixed or casement styled block or prevent this natural cycle from happening!
Worse still, windows with top openers or which hinge from the top, act as hot air scoops.
As buildings warm, so the air from streets and pavements climbs the extranal brick face, when this air hits an open top hinged window it gets scooped into the room, thus raising the internal room temperature EVEN higher! Now please open windows, even if you have casements, just not beyond the outside face of the wall, that way you’ll get some relief and avoid additional overheating.
Don’t forget, thick curtains will help insulate your home at this time of the year. If you draw them too, on south facing elevations, you’ll avoid rooms becoming too hot, however if you can also open windows on other sides of the room then the through breeze will assist further.
Lastly, don’t forget to throw open all your windows for a few minutes at night. Its amazing how much cooler the rooms are if you can ventilate them before bedtime.
Good ventilation also helps for a peaceful nights sleep.
