    They work a treat!

    Bought these a while back and thought I would see how they worked before reviewing. As a woman on my own, I am never sure if I trust the words of builders as I have come across some cowboys down the years. I needed more of an air flow through the loft area to reduce condensation patches in the loft and after googling what I needed to do, I decided to have a go on my own. These have worked really, really well. It was a bit fiddly to fit them, but I am amazed at the difference to the condensation problem this winter. I am really proud of myself for getting to the bottom of the problem and fixing it myself. This is such a simple idea and easy peasy to fit. Couldn't be happier with the results. They do seem a little expensive for bits of plastic, but due to the fact that they work so well, means it was worth the cost. Very happy customer

  • Most critical review

    Flawed

    Good idea but has issues, wether it works depends on a few factors such as the amount of overlap your felt has, a large overlap and the vent is not able to separate the felt at the bottom to allow the air in. I had issues pushing many of the vents in because of nails being in the way, also when correctly in place the gap it creates is an opening for flies and insects and such into your loft space, If your felt is a bit old it'll just break when you try to separate and insert

  • Here's to a dry roofspace!

    In recent winters we've experienced annoying condensation problems in our roofspace. Putting in soffit vents made some difference, but didn't eradicate the issue completely. Whilst browsing an online DIY forum I came across a recommendation for these lap vents from someone who claimed that a condensation issue with his roof space had been completely eradicated after he fitted Manthorpe lap vents. So I bought some, fitted them and I'm hoping to be able to wave Bye Bye to condensation in my loft this coming winter. Unlike more expensive solutions to roof space condensation, they're very easy to fit, and also easy to remove if you want to move them or decide they're no longer suitable.

  • Easy and immediately effective solution

    Having topped up the loft insulation to 300mm I wanted to insure there was good loft air circulation to prevent condensation in the winter. This product is ideal as it is really easy to fit between the under tile felt wrap-over. I could immediately feel increased air circulating through the loft trap as I exited the loft. The supplier is a good one and the delivery was made ahead of schedule and I managed not to put my foot through the ceiling. RESULT!!

  • A Simple easy to install and cost effective solution to vent your roof space

    Took about 10 seconds to install the 1st vent and about 5 mins for all 20 to go in. The Companies website shows where they should be placed for best effect, Such a simple idea and so effective. Wish I had heard of it nearlier

  • Vents

    Although these don't meet building regulation requirements for full condensation control ,but great for refurb where major condensation is not the cause to use these vent . Would highly recommend these as quick and easy to fit they done the job which I intended to do .

  • Easy to use.........

    Having moved into a bungalow just four months ago, I quickly realised we had a condensation problem. Together with roofing vents ( done)and gable end vents (still to do), these little stars just clip in between the felting to allow a little air gap which helps to allow the air to flow freely around the loft space. I fitted ten, which is five each side. I'm probably going to order ten more, I'm that impressed.

  • Not yet 'tested'

    Prompt delivery and well made. Easy to install, but it might be a good idea to wear gloves to protect your fingers from scraping on the roof felt. I put them in the loft just yesterday and haven't been back up to see if they have done the trick and got rid of the condensation hence only four stars.
