Hello, and thank you for your enquiry. We would recommend the GCA / Butyl bead tapes for this application - Matt, Product Support Manager
A sample of the Reviews for some of our High performance GCAS Butyl tapes in this range
Don't take our word for it, see what some of our past customers have said about products in this range.
The sealant tape we bought from PSA Solutions was good quality and at the right price. We used it as a lap tape for 6000 square feet of profile sheeting and associated flashings. We have no hesitation in recommending this product and will use it again on the next roofing job we undertake.
Great product, work wonderfully for sealing door panel of my Seat Leon mk1. Easy ordering process, fast delivery, good quality product.
The mastic tape is a very effective seal 100% waterproof Easy to apply and easily managed.
5 star I use this for adhering a moister hygrometer to a subfloor To determine the amount of moister in a floor. Far cheaper than my trade suppliers and delivery Was spot on too.
I used this product to install and seal a Motorhome Roof light in to my Citroen Relay van. Because of the ribs on the roof I was finding it difficult to just seal properly with silicon sealant. After doing abit of internet searching I came across PSA Solutions found this product. It has exceeded my expectations considering to excellent price. The roof light has not leaked even with strong winds , heavy rain and travelling up the motorway at 70mph. If your looking for an excellent sealing product then I would highly recommend it.
Needed to replace the glass in 2 Velux windows. As Velux overhaul kits very expensive decided to buy the glass locally. Not possible to get original glass at 3-10-3 however 4-8-4 is available and also has an E coating so not much different. Needed a sealant when replacing and the original 5.5 mm Velux butyl sealing bead is ridiculously expensive so purchased from PSA at a very reasonable price. Size is not critical and 6 mm has worked fine. If I had purchased all from Velux cost would have been about GBP 160. Using PSA sealant and local supplied glass the cost was about GBP 65. So overall I would give a score of 5 to PSA both for quality and price.
