In a prior life I was a plant manager there.
I do understand, the wall comparison is because even if the wall is sealed 100% it's still not considered insulation, the R value is almost...
I wasn't confused by your question, I understood you wanted to understand the R value with a laminate on both sides. It's low, to the point of not...
Frequently when stronger fibers are used and the laminate becomes thinner you end up doing other things to regain stiffness and durability, or at...
As fallguy says, it's so low that it isn't worth researching or advertising on their part. Plywood has an R value, but it's not considered an...
If the keel was a separate component and attached to the hull, then it's a sacrificial piece and is intended to take a beating and look like that....
Looks like there is a core in that section, it will probably be foam or balsa wood. If it has been exposed to the weather it will be wet, this...
If what looks like air in some locations in the fabric is just thick and discolored epoxy, then it would lead me to look at the silica. Silica...
It looks like there's quite a bit of air in the laminate, plus epoxy weather's poorly, so discoloring after UV exposure is normal.
The differences between manufacturers, and the difference in products within a manufacturers lineup can be significant. Glass can also be...
Your laminating resin cured tack free because DCPD isn't as air inhibited as other types of resin, it will become tack free on its own in a few...
Under cured and changing shape after its been de-molded. Up the skin coat catalyst level to at least 1.5 % or more. After infusing leave it in the...
It has been tried for many decades, without government funding it isn't profitable enough for great success yet. Regulations and other...
Magnum is the most common and is supported just about everywhere. Phoenix is a bit less common, but I've heard good things about it.
What made you choose surfboard resin?
The degradation takes quite a while and starts at the surface, the initial oxidized layer protects the underlying resin somewhat. This surface...
Putties, fairing types, make a poor mold or plug surface, sticking is very common. They need to be covered by either the same resin type, a...
They didn't fail as is, but you can do whatever let's you sleep better at night.
What you see is typical construction for the that time, it's piss poor, yet didn't fail, and other than rotting, most didn't. What it means is...
What makes you feel the original build wasn't up to the task, did it fail in its prior life?
