Thats correct, they are not cheap, but they aren't cheap either. Typical travel trailers are built using plywood, (kown as "stick and tin" in the industry) certainly come at a lesser cost based on the lower quality materials used in manufacturing

@boreascompositepanels Not dogging you. If you can get those kinds of prices good for you. It seems to be based on market price not cost plus.

Hello, the overall thickness is 1.78 inches

I was thinking the same thing. The mitered corner would place the rivets much further inboard from the edge of the fiberglass and give the Sika an actual surface to bond to rather than just being pressed onto foam (which has no strength).

There is always more than one way to skin a cat. The Boreas Campers product uses butt joints in its construction process. This requires a larger peice of alum angle to cover the corners. We just posted up another video using a lap joint. The lap joint process will be used in our pre cut and/or pre assebled camper kits. Here is a link kzfaq.info/get/bejne/o7-UlNebtM-ZcY0.html

Yes, that is correct at the $17 per square foot. We do have a select panels sizes available at $10 per square foot

Thanks a lot!

You are able to bend the panels up 20 degrees for a sloped roof or you can cut multiple pieces to add angles. No interior struture is necessary, but yes you can cap the corners if desired for asthetics or additional strength. Small conduit on the exteior of the walls works great for running wire. Check out @boreascampers for an example of this composite panel and aluminum exoskeleton system

Nailed it.

Thank you!

Yeah, I’d have just done a full length piece nice and strong and not visually abrasive. On all four corners, may add 5 lbs and $75.

I know that many pontoon boat manufactures are going to composite decking/floors as opposed to marine plywood, however, I'm not sure what their exact specs are. Using our panels as a floor is not an issue. You do need to have support members at a minium of 18 inches. I also recommend using a secondary finish, such as LVL in high traffic areas.

I like the material & it looks like it's easy to handle. Tough -n- light weight is all good. I'm still researching but I wouldn't use plywood anyway, not marine or any other b/c it's too heavy. This stuff has some good attributes but do know if can be covered w/ fiberglass? I'm real new to all of this & I thank you for sharing the info here. I do like it, thanks a lot.

Good call

None

@alsnyder1660 look again. SikaFlex was used

​@@kevinrusso6849wrong

​@@michaelcagle4662you blind? Sikaflex was applied

You do not want to fully compress the bonding surfaces and squeeze out your adhesive. With the XPS foam core being porous you are able to keep a tight bond line.

Thats correct you do not want to have exposed edges on the panels. However, the water intrusion needed to cause any type of delamination is infintiley greater than a traditional plywood (stick and tin) camper. When you cut a hole for a door or a window the FRP and XPS foam core will stay bonded together and you won't need to glue any exposed edges. Just make sure the final installation of the door/window is well sealed.

@@boreascompositepanels What sealant do you use/recommend?

Thank you!

The overall thickness of the panel is 1.78 inches

Great, thank you!

I saw a video from Australia showing i think 15 people standing on the roof of a similar construction trailer. No frame required is why this construction is so awesome. I build mine with moulded rounded corner construction and no caps, still plenty strong but not for offroad. Great to see a company selling product for the DIY crowd.

@@steveogilvie5203 I would love to see that! I'm trying to figure out how to assemble the roof transition, I wish this video explained it...

@@hellogoodwin i have built 3 so far. I use a removable wooden mold. I won't post a link but I have made lots of videos, just do a search.

@@hellogoodwin Styromax has posted lots of videos too. You might find your answer there .

Thanks Steve!

thank you!

thanks!
