The £3 B&M window hack to keep your house warm – it ‘prevents draughts, reduces heating costs’ & stops condensation

CONDENSATION is a common sight in millions of UK homes during winter.

But B&M claims to have the answer with a £2.99 item.

Exitex Secondary Glazing Film is said to "keep heat in your home".

It works by "creating a double-glazed window effect to minimise draughts in the home".

The product description continues: "A simple and cost effective way to keep your home warm and save energy."

It also "prevents draughts" and therefore "reduces heating costs".

And what's more, it only takes 10 minutes to install.

As for how to apply it to your windows, there are a few steps.

First, cut the film to the size of your window and attach it carefully to create a seal.

Then, using a hairdryer, shrink the film with hot air until it pulls really tight.

If there is any excess film around the edges, trim it.

As for how well it works, reviews of a similar product on Amazon give it four out of five stars.

One customer said: "I was so sceptical about this product and reading some of the reviews, I was hesitant to try. I am so glad I did.

"No condensation at all anymore and it’s certainly warmer in my rooms.

"It is so easy to fit, I am confused about the reviewers citing difficulty; each windows took me less than 5 minutes on my own.

"I didn’t pre cut it either, I got an approx size, applied the tape, and started from the top, stretching the sheet wide as I pulled it down too.

"I can barely see it on my windows. Would highly recommend this product, I wish I had purchased it sooner!"

Another said: "It's been on my bedroom windows for about a month and a half and since then condensation has been a very low amount.

"I left a decent amount of extra plastic at the bottom to allow any condensation that will (and does) form on the plastic it will not get on the window sill itself which really helps prevent damage and mould build up.

"From the first day of waking up with it on my windows, I noticed the room was a lot warmer from the days before, and it was on average colder outside.

"This means it helped keep heat in the room a lot, which is great to wake up to.

"Only issue is I will probably have to take it down in the summer if it gets warm as I don't want to melt in this room.

"I would really recommend this product as it does the job really well, however I would suggest you get a friend to help you out to set it up just to make your life a little easier."
