Up to the test of time
5 Dec 2012
By DannyMic

"I've used this felt several times and found it easy to use strong and durable, but what surprised me the most I used this felt about 8-9 years ago on a job where i just replaced the bottom course of felt three rows of batten etc the customer then phoned me a couple of weeks ago and asked me to do the entire roof as they had a bit of storm damage and a couple of ridge tiles had blown off etc but to y surprise when i stripped the roof the bottom course hadn't even began to deteriorate it was still like brand new which was a shock considering the old bitumen type felt use to start rotting in the gutters after about three years highly recommend to trade or diy"

"Of all the various membranes out there this one has good tear resistance and is reliable. The material has a good water resistant and non slip surface which is good for tradesman safety"

Great for sheds
2 Aug 2011
By Hanno
, St Ives, Cambs
"I used this on a shed before laying felt as a double-insurance. It's thick enough that it doesn't rip easily and easy to work with.
I bought some more recently to line the inside of large flower boxes to give the wooden surrounds a longer life. Great product."

My number one roofing underlay
28 Oct 2008
By Umboman
, Trowbridge,Wilts.
"Fantastic product,easy to use & cost effective.I have used this as the first line of defence on my sheds,garage,bin store & arbour.I have covered it with garage felt,feather edge wooden boards & green corrugated bituminous roof sheeting.All with 100% success in weatherproofing.
It is not tear & uv resistant(like VP400) but is half the price & as you have to cover it I have had no problems with tearing or perishing.I prefer it to traditional felt underlay(& think it gives more value) & theoretically as long as it is covered & secured down with galvinised staples it should continue to provide long term back up if your top covering fails.Even under wooden feather edge it is still performing well,but be careful using some wood preservatives as they can eat into the protect A1.
I used it stapled to a flat suface(chipboard) & hung over joist's 18" apart(arbour & bin store) with no problems.I think when protect A1 is used with 10 year garage felt or green bituminous corrugated sheeting I am very confident of no problems or maintenence issues.Feather edge carries more risk & I have never built a house so cannot comment on its intended use?
Buy with confidence.

"Used this as underlay for a pantiled verandah and it's light, strong, waterproof as promised. BUT take care to drape it well if you're laying it in sunshine. It expands a good deal when warm and if you leave only the recommended drape allowance it will tighten like a drumskin when cool."
