1708 Fiberglass Cloth: 17 oz Biaxial 3/4 oz Mat Back
Fiberglass Biaxial Cloth is a #1708 E-glass Biaxial (+/-45 degree) Cloth with 3/4 oz mat backing. The fiberglass tows are held together by light nylon stitching which do not affect the structural integrety of the cloth.
The flat non-crimped fibers yield reduced print-thru and higher stiffness than other woven fabrics
The mat backing adds extra thickness and makes for a smoother finished product when applied over scratches and dents. This cloth is ideal for repairs, tabbing, and reinforcing.

1708 signifies the weight of each layer.
+/- 45 biaxial weave cloth is 17 ounces per square yard.
mat backing is 8 ounces per square yard
yields a total weight of 25 ounces per square yard
Does this happen to be shipped rolled or is it folded?
It is shipped in rolls.
What is the general thickness per ply with hand layup?
1708 with mat backing is @ .042" thick. To build up 1/4" of biaxial cloth with mat backing, you would need approximately 6 layers. (.042" x 6 = .252, or approximately 1/4")
how many layers would be required to make up 1/2 inch in thickness, using epoxy?
Hi Jed, its very hard to answer that because it depends on whether you are doing a hand layup or a vacuum bag setup, and depending on how much pressure is exerted to remove air and excess resin, we really can't pinpoint a number.

Can this be used to build a fiberglass pool?

I need to add firmness to my boats upper deck after removing the teak. It is 7 by 13 feet. Will this product do the trick and if so, will one layer be enough?
Yes the 1708 biaxial with epoxy or polyester resin will strengthen up the area.

This product states it is a pack - can you clarify please?
When I bought it, the cloth was rolled up in a 3' roll and simply covered with brown paper.
This was delivered to me as a roll, but perhaps it depends on how much you order.
Clarification.... Brevity is key.Folded pack, not roll.
I am looking to make my own shower stall. I have seen this done with the mat before, however, I do not know how the product comes. It references PK? if I order the 3 yard product, what are the dimensions?
Janice,I think the product your looking at is a 3yard piece of material. Thus a package (PK) of material that is 38 inches wide by 3 yards (9 feet) long. I hope that helps.
This comes in a 38" by 3 yd package or 50" wide sold by the yard. Also the 38" width comes in 10 yard and 25 yard rolls.
Janice, The widths available for this product are 50" or 38" on the Jamestown website. You will have to check with Jamestown directly, but a short length is likely to be folded, and a long length is likely to be rolled.Building your own shower stall from scratch is quite an undertaking in terms of cost, along with the resin & hardener. To achieve a nice looking end result will require considerable time, even for an experienced user. However, Jamestown has all the necessary products at a fair price if you decide to pursue this project.Good luck
is this product equivalent to the west 738 biaxial fabric? I assume you put it in with the cloth up -- smooth side up?
Biaxial is what you want to use with epoxy resin. It's chopped strand mat on one side and woven on the other and very strong when laminated in multiple layers with epoxy resin. I only used west systems epoxy for one part of my job,and a different companies (non-blushing) epoxy for most of by bow rebuild project. Chopped strand side down. Epoxy doesn't like UV rays, so you'll need to paint or gel coat over if exposed to sun
Hi Jill,I'm sorry I do not have a specific answer to this. In order to verify equivalency I would email the manufacturing company w/ these type of questions. What side of material to use would also depend on what it is being used for, and the environmental conditions it would endure. For example: will it be used next to solvents,acids, high or low temperatures. Also if you use this in a specific way: sculpture or repairing boats etc, I'd talk to specialists who already do that kind of work/repair to get their opinion.
Fiberglass Biaxial cloth is stronger than the west 738 cloth. The West system is for light duty, surface layups. The Fiberglass Biaxial from Jamestown is ideal for heavy duty layups such as inside corners.You are right Gill - smooth side up!Derek

Can you tell me if this is used with the 105 epoxy resin and 206 hardener?
Gary E. Sims
No, it's used with polyester resin. It's csm with cloth stitched to it
i used mas epoxy had to thin it a little i was happy with the cloth
Sure, but the cloth is thicker and will take more than the usual cloth.
Gary, I have used West 105 (any hardener) and MAS epoxy with this cloth works fine. The biaxial cloth is stronger and does not unravel when cut. It takes about 128cc (16 pumps) of MAS resin for a square foot. The slow 206 hardener is especially good over 70F. BTW, Biosolv is good for cleaning the grooved fiberglass rollers. Put it in a container of Biosolv, wipe dry later and reuse. I use white vinegar for cleaing resin from my hands. Good luck!
Yes, I used West 105 & 206 epoxy building new amas (pontoons) for my trimaran, I used 1708 biaxial E-glass and also one layer of carbon fiber.Ron
Yes. I have tried several brands of Epoxy and have found that the West systems with the pumps is the most consistent and easiest to use. I have successfully used the 105/206 combo with several different cloths from 4oz to 8oz as well as biaxial cloth. Just need to make sure that you saturate the cloth fully.
Biaxial is the way to go with epoxy...I used west systems with it and it worked fine. I also used another local brand of epoxy as well and it worked great too. You can tint the epoxy with typical pigments used for fiberlass. You can also add cabosil or other fillers if you need a little thicker epoxy. I rebuilt an area on the bow that had rot and supports a windlass. The repair is super strong now. Epoxy doesn't like UV light so make sure and paint or even gel coat over, just sand a bit if you gel coat over.
That resin system would work fine for this cloth
the price sais per pack what is in a pack?
The pack just designates that these are pre cut, you can use the drop down menu to see the correct length you require..< a href="http://www.jamestowndistributors.com/userportal/show_product.do?pid=1441" target="_blank">http://www.jamestowndistributors.com/userportal/show_product.do?pid=1441< /a>
1708 is an amazing product!
I purchased a 1990 hurricane deck boat that had been neglected for years. The foam was saturated with water and most of the wood stringers was rotted or rotting. After researching many options I came across 1708. I am glad I ordered and used this product in my total boat rebuild.
Great product for fast thickness build and durability
First impression is that this is some thick material, great for fast lamination, or single layer over wood. I was pleased to see that the product is shipped rolled up, not folded, to avoid kinks in the glass. I used this as a glass layer over a replacement plywood transom on a dinghy. I will use it again as a tough deck lamination over plywood. I used west system epoxy, best to not overwork the material. Requires minimum fairing after installation. Great fiberglass!
Strong enough for the bumpers on my race car.
This mat is very strong. The fiberglass bumpers on my race car were cracking but not after I used this mat to help support them.Perfect product.
great price , American Made
I used this type of cloth for most everything. I have seen people say it is hard to wet out, not really. Lay some resin down first, place cloth over it and lay some resin on the top , work it with a brush slightly and wait a minute or two. Then add additional resin as needed on top. It wets out great and you have plenty of time to work it if you are using the correct hardener . This cloth does not wet out clear it turns green , keep that in mind for your application . The cloth will form arround contours very well once wet out. I have used it in multi stress loaded areas by positioning the layers in different directions , or you could use triaxial or quadraxial cloth but the don't contour as well.

Very good with epoxy
Used this glass to laminate a new bulkhead using MAS epoxy. It wet out easily and handles well. I've also used it for tabbing where it conforms to curves and corners equally well.
Great for fabrication of motorcycle parts
I try and make custom motorcycle parts for my bike and this material works great.
Easy to work with, made a perfect repair
I had to re-glass a deck repair on a 32 year old boat and make it blend to un repaired section.this cloth paired with epoxy resin was easy to work with and gave me the finish I was looking for
Quality fiberglass mat. I used this product when I re-cored floor hatches. I used it in conjuction with TotalBoat epoxy and balsa core. This was my first time recoring hatches and my first time using biaxial cloth. It is a bit difficult to fully wet the cloth; you have to spend some time working the resin into the cloth. This was not an issue on a horizontal surface, but might be difficult on a vertical surface. That said - My hatches are now rock solid. After re-coring two rotted hatches, I used this mat to add another layer on a floor hatch that had IMO too much flex - it is now rock solid too.
Used this biaxial and CSM fabric to rebuild Rudder on a 82 hunter
i've fixed three transoms on glasrtron boats now and this is the best product i have used. it wets well but you need to make sure that the resin is at a warm temperature. i had the resin in the garage and it was a little thick at first. the flat roller and corner roller work great when forming. for the beginners, try to wet the structure and both sides of cloth before you lay it in. of coarse i mean this when you use it on a vertical not horizontal. good luck!jamestown was the best price for all the materials i purchased. resin, rollers, fiberglass(cloth, mat) and don't forget the pumps.
