Welcome to our forum.
I think that is what the dealer said. Maybe he said R-19. It's a HS grandee, and the local HS dealer was talking about the R value of the covers for all of the HS lines.
Ever the practical one, let me add this to the mix:When you look out in the morning and see frost on the cover of a 102 degree spa, does that mean that there is no heat being transfered through the cover?it seems to go away first at the seam, but then the rest of it stays until the sun hits it, and it goes away exactly as the sun travels across the cover, or it will go away en-masse if a the temp climbs quickly as is Santa Anna winds coming up.
Can you say lineal heat seal?
Stuart.....now who do you know that uses a linear heat seal....
It starts with an M and ends with ARQUIS. If you have trouble figuring that out call me.....
Do you mean MHotSpringarquis? No, I guess not.But I like the idea. I don't know how much it adds to the cost of making a cover, but it sure looks like a good thing to have.
"Can you say lineal heat seal?"No I can not We call it a hinge seal"It starts with an M and ends with ARQUIS"mROBERTS HOT TUBSarquis? hmmmm, I'll discuss a name change at the next board meeting.......As far as efficiency, the HINGE SEAL, adds from 3% to 5% more insulation value to the total cover. The larger the cover, the less over all percentage.
This is getting way off topic. I say let Arctic's slip down the list and/or start a new thread on covers.
how about MdimensiononeARQUIS............or McalderaArquis?
