Added Insulation

Although we now have double glazing on all our windows, we don't have shutters on a couple of them. This means that although outside heat doesn't make it into our house, direct sunlight through windows can cause a rapid increase in temperature. This is called solar gain and is not a good thing.

In 2019 I wrote about hanging my old beach towel over the back door, an approach that works well, and which we still use. This still leaves the problem of the windows in the kitchen.

I now have a new approach, which involves aluminium kitchen foil. All you need do is tear off a suitable length of tinfoil, wet the back of it, and apply to the outside of the glass. And that's it. Works superbly, and if you're a little careful you can remove the foil at night and reuse it time and time again. The water tension holds the foil in place in even quite high winds.



Even this slipshod application was massively effective, but by the time I had got outside I had already spent too much time in the heat, and couldn't be bothered making it look good.

Of course, as soon as I worked this out it has cooled down for a couple of days, but I have no doubt I'll be applying it again within a week.
