Serious subfloor shrinkage!

Weezbo

You are right. two summers ago heading into winter, same sh different person... looked like the ripples on the deep blue sea. some of it thickend up some of it shrank back, 1/4" gaps ? no problem those were some of the good ones. risers sags man it was a mess. buh i have to say rain blasting down on the wood on the deck was THE cause. turn the heat off altogether, drill a hole into the floor here and there, the moiture will slow a timberwolf down to a snails pace with a new bit.

Ran fans in the crawl space for maybe a month to get the moisture out of it, pumped base board on the perimeter..

The contractor calls in a panic

I need heat for the sheetrockers to hang and tape. No problem I say, and head over.

I get their and look up to see there is no insulation in the ceilings. Contractors tell me it is all spray foam and they need the sheetrock taped before the foam. Make sense, I suppose.

So I crank up the radiant wondering if I can even get 50 degrees for them.

I took the boiler all the way to 135 on the heat transfer plates trying to warm the space. Engineered wood products people tell me 140 is the max continous temperature for the woods and glues, so I stopped at 135 supply, from the Ultra.

The Advantech subfloor has opened up 1/2" in places! Surprised me. Glad the hardwood wasn't nailed down.

This home was framed in the spring and saw a lot of rain, but I thought this high tech subfloor was geared for that.

I did get hhe place warm enough, however and turned the temperature back down to 110.

good thing

HotRod,

I't a great thing this happened now. If it had happened after the floor was down, they would be trying to blame you for ruining the floor. If it happens on your shift...

I make sure these contractors

are aware that I do not have to supply heat for the drywall guys. One time the stone masons drained all the glycol mix out of a system to mix mortar when it was 30 below. Day before Christmas. 80 miles away. I got a big laugh when the rocks fell off the chimney later. Drywall guys are dangerous and should supply their own heat. I used to bring a big Modine power vent unit heater and set it in the basement and hook it up temporarily; it worked well for several jobs, but then they destroyed it as well.

Shrinkage but no sign (at least can't see) any delamination or edge swelling.

Shrinkage!

I was in the pool! I was in the pool! :-)

Not shrinkage,
