Eagle windows recommends a 'non-setting, non-adhesive butyl based compound' for resealing the aluminium window frames to the grp window openings. I have tried ringing them today but kept getting an answer phone. Does anyone know the name and manufacturer of this stuff.
Thanks.
 
Well done Amulet. But you can download the sealant section of their catalogue and discover Arbomast BR- Butyl rubber sealant. I think that's probably the stuff that Eagle suggest.

Available from various chandlers eg Marine superstore

even Marine megastore :D :D

We recently replaced the windows on our Oyster 435. Houdini windows supplied the windows along with the sealant, which I do believe was Arbosil unfortunately cannot remember exact reference. However, you can check out by either contacting Houdini windows http://www.houdini-marine.co.uk/ or Arbo http://www.arbo.co.uk. Since fitting the new windows we have sailed from Uk to Greece. Had some serious amounts of water engulfing the windows and not one leak which I put down to both very good windows and sealant and maybe a small amount of good workmanship by us.
 
The butyl sealant they are referring to is probably available at a good hardware store or a caravan (rv) dealer. It comes in a roll separated by paper as shown. It never sets hard and has the most elongation of any sealant. My hull/deck joint is sealed with this as well as all original deck fittings, 32 years and no leaks.

I think we are looking for gloop not a roll - or have I misunderstood? btw Marine and Industrial will deal with small DIY quantities in my (a few years ago) experience. Also, although you can download their catalogue I find it pleasing to have the book. My ability to sit of an evening and read something entitled "Marine and Industrial Sealants" annoys my daughters pleasingly.
 
Arbomast BR ... Confirmed by Tradewinds as the product that Eagle windows supply ... is not a tape!

It is not supplied on a roll

It is a butyl rubber sealant supplied in a cartridge

From the data sheet ... the link to which I gave earlier ....

Application
Arbomast BR is supplied in cartridges and can be applied into the joint using an Arbo Caulking Gun
 
I have used Gutter Sealant on a leaking window.
It was done about 6 or7 years ago and is still effective.

Another source?

I have some in a roll made by 3M (08611) (8mm dia x 4.5m) which comes with a primer too, for sealing windscreens. Recommended on a Swedish Maxi site I think for replacing Maxi windows.

That too is a butyl rubber sealant! Only available in black, while Arbomast is also available in teak and grey, but probably somewhat less expensive.

The butyl I recommended is available in grey as well as white and black. While it is available in cartridges it is commonly sold in hardware stores for $5 CDN a roll (much less than any other sealant) which will last a long time. It has no shelf life and is the first choice for ports as well as any hardware above the waterline. Iy requires no primers and only clean degreased surfaces. Much better than Sika or 3M products for marine bedding. I looked at the link you posted and except for the skin in 24 hours seems to be the same. I know of no other sealant that will stay flexible and keep a joint water tight for decades. It is fully compatible with any plastics used on a boat including acrylic and polycarbonate. It is commonly used in the RV industry.

I know many people like the tape for sealing windows but the original question was to specifically identify the product that Eagle Boat Windows recommend.

I knew they recommend a butyl rubber mastic, I thought it was an "Arbo" product but could only think of Arbosil which was obviously not it.
Amulet posted a link to a catalogue that identified Arbomast BR. Tradewind subsequently confirmed it to be the product supplied by Eagle.

The answer to the question originally asked is therefore Arbomast BR !

I have not tried the tapes you suggest but I cannot see that they would be a good choice for windows in frames the shape of those on a Sadler 26 ! I'd opt for a gunned mastic even if I might prefer tapes for windows of a more angular shape, especially where the glazing is not in frames.

Eagle describe the method of using the mastic on their website.
 
Find a Travis Perkins and buy their Oil based mastic. Recommended by my window repair guy that did the windows on my boat. About £4 a tube.
 
I agree that the stuff recommended is likely to be Arbomast BR. I have a tube of it right here. It is non-setting, and described as a Butyl Rubber based sealing compound on the tube. The tube is bigger that the average B&Q bog sealant tube size, so you need a bigger gun to apply it.

Quorning, who manufactured my boat, use it to seal alloy window frames to the hull, and I'm pleased they did. I had to replace a hatch, so I asked them what to use and it is this stuff they recommended. I was expecting the usual fight to get the old hatch out, but because the sealant doesn't completely set, after removing the retaining ring, it just popped out. I had a new tube of the goop to seal the new hatch in place, but the old stuff was still in such good condition and gooey that I reused it.

No window or hatch has ever leaked for me because of seal failure so far.

Whilst the recommended stuff is probably Arbomast, I have experience of the stuff on a roll that caravan makers use. I fitted a plastic roof vent frame to the aluminium roof of a caravan with it about 13 years ago. It remained leakproof despite water sometimes sitting against it, and even freezing, so I would not hesitate to use it. (I did have to re-bed the frame a few years ago, because it was also screwed down, and the screws rusted and eventually let water through.) Any decent caravan dealer or repairer will have it. (and probably much cheaper than any boaty stuff.)

P.S. I just re-read the original post and noticed that the recommended stuff is non-adhesive. The caravan stuff is adhesive. Is there any reason why your bedding compound should not also stick the window frames in place?
