Do not use this company. I ordered some acoustic foam from Efoam. We ordered a slightly bigger piece, more than we needed to ensure there were no gaps in the frame it was going into. There was no reduction in noise whatsoever. The foam was thin and more like something you’d use in a case to protect camera equipment. The foam arrived with two marks on it which I didn’t make a fuss off as when it was up you'd not notice them. So I sent a friendly email to Efoam stating the foam had made no difference in noise reduction at all. They asked for photos which I sent but they came up with every excuse in the book. Basically they said nothing they can do. So I sent the foam back they said it had marks on it, which were the marks I was referring to earlier in this review and white hairs on it, which is odd as I don’t have any pets. They said they would not pay a refund and after this they ignored my emails. In the end my partner emailed them and after a few days they said they’d pay £15 back as a good will gesture. So I’ve ended up with no foam and only £15 refunded, this product cost me nearly £40 I did however write to trading standards they replied and told me a route to go down and said I’m well within my rights. Unfortunately I have a chronic illness and this is more hassle than it’s worth. Don’t go down the route i went down and use this business. Stay clear. The acoustic foam isn’t fit for purpose. Please find attached a photo of the piece of foam in situ. The marks on it…
