"I used this product to waterproof my summer house walls prior to installing insulation. It has provided a barrier between the wooden walls and the insulation to keep the inside completely dry. It rained shortly after I installed it and the inside was bone dry - maybe another use for this versatile product!"
"Bought this to do a small repair on my porch it was that easy to use I ended up doing the whole porch roof, A1 is the right name for this product, if it holds up as good as it was to use you will never hear any complaints from me.billm"
"Bought as a temporary cover before I cover the roof of the garage with Cladco. Was going to use my breathable felt, but at a 1/3 of the cost this presents excellent value for money. I'm also going to try it as an alternative to breather felt for vertical slating. Would highly recommend this product."
"Bought this as an waterproof underlay to lay on a cabin roof prior to putting shingles on.it meant that I could take my time knowing the cabin was watertight also an extra layer of protection.does the job and was the best value by far.would use again"
"Used this as underlay on a pitched roof and it was left exposed for about 2mths in the worst part of winter and it gets really windy where I am. Even after this it didn't let a drop of water in and shows no signs of ripping or tearing , even on the loose flaps exposed to the wind."
"I am constructing an all weather tree house for our three amazing Foster children so needed quality roofing underlay to facilitate over night camp outs. Brilliant product will be back for more if the children decided their tree house needs an extension!!!!"
"Needed some roofing felt to line the inside of my roof space to stop everything getting covered with dust and dirt. This fits the bill perfectly. It's excellent value for money, it's easy to cut but is thick and strong enough to provide excellent cover. Very pleased."
"This material was designed to replace bitumen roofing felt but it is so much more versatile than the old felt. It can protect a roof without any other covering for 6 months at least. I use a piece in the back of my estate car to protect the carpet and cover tools from view, it has been in there 5 years and still going strong. Excellent product would thoroughly recommend."
"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"
"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."
