Understanding Fiberglass Types - Different Weaves, Weights and Uses - Basics of Fiberglass Fabric

We discuss the different types of fiberglass reinforcement, including woven vs stitched, cloth vs mat and more. Including why we use certain types of fiberglass on certain boats and a few helpful how to tips too. This includes several types of fiberglass we use in our boat designs - 10oz cloth, 1208 & 1708 biaxial 45/45 and 1808 biaxial 0/90. Learn how to select the right fiberglass for your boat build.

You can build your own boat using our plans and instructional videos!

Super informative and easy to follow! Keep up the good work!

this was the most informative fiberglass video I've ever watched. Thank you.

[rosalindewinston]

nice to hear it explained. chop is for soaking resin. i didn't even know you had option to have a woven top on it. thanks. I don't build boats, but jigs.

Really helped me in replacing my transom thankyou

Very informative video! I’m planning on using a 6 ounce cloth and EcoPoxy on a small rowboat I built using Glen-L plans. Does it matter which side of the cloth goes up and which side is down on the plywood?

Great tutorial for beginners wanting to understand fiberglass types and their applications.

[Uae_streaming]

Please explain more about ( what will happen if we glassed full new boat hull with 1708 only ? ) do we have to use 090 in a boat if yes please make a video about it and how to lay the mats and where )

And how the boat will be effected if use one type of mat or 2 types

[philipthomas]

Which one of them should i used first in the building the bottomof the boat?

[philipthomas]

So if i have to build a new fiberglass boat which glass should used?

[haziqhashim]

Is woven fibreglass and 0/90 fibreglass the same ?

[khalidalbagdadymd]

Many thanks for this nice video, may I ask you what fiberglass type I can use to seal under waterline small holes ? I am going to fill them with epoxy and thickener but for more safety I would like to use fiber glass cloth also . Thank you

[yasermohmmmed]

Can I use this type of fiber to manufacture (the panels are flexible)
Or is this a type of fiber that is not flexible?

[outlawflyer]

ok, so I have an 18 foot sailboat that I need to do a mast step repair where the wood is rotten and I want to replace with nothing but fiberglass. Build up layers. which is best for this project?

[richardwallinger]

how about a coremat and chopped strand fabric layup.

[borna]

Great Video. I know this is related to boat, but I am working on classic car and there is a piece of metal rusted and I want to replace it with fiberglass instead of welding a new piece. which cloth and resin you recommend?

[lostattheoffice]

Thanks for the video. What type of glass would you recommend for stingers in a 15' fiberglass v hull? The 1708 looks like the stuff I cut out. And how many layers do you recommend for adequate hull integrity?

[Rick-tbso]

I have seen boat builders use matt shot out of a gun, how would that be strong ??

[bornsublimis]

“I don’t think an extra gallon or so of resin is a bad thing when it comes to the strength and integrity of the structural components of the boat”

Adding to much resin can be a bad thing.
Adding to much resin can cause the fibres to “float” and not bond together which will cause weakness. You don’t want a a lot of resin, you want enough to wet it so it bonds together. (Getting cardboard or a smooth wooden bench to paint it onto the glass works) If you use too much resin, use a roller to push the excess resin out along with your air bubbles.
Clean with a rag and acetone.
To keep your glassing bench clean (if not using cardboard) lay down strands of chop with resin over the top when finished, let it go hard. It will peel off as one and leave you a smooth working area the next time you use it.

The itchiest of them all is glass veil tissue
