[Greenbuilding] fastening a subfloor over foam over a slab

[JOHN SALMEN]

I agree. I keep looking to have the envelope, structure, insulation, and
finish as distinct items and it gets very difficult. I made a big argument
for adhesive because it works for that detail and increasingly to make
things work buildings are glued, screwed and impossible to get apart.  I'm
still trying to figure out whether to mechanically adhere an eifs project
but have heard very good arguments from wjohn to equally consider the
adhered system as that is what is being considered the workable approach.
I'm sure that ground up foam, polymers and cement will have some market at
some point - or we will be cursed for it.

 

Ironically we just had a project that involved removing a small building
(1960's) so I looked at the cost of the big dumpster and thumbed excavator
and then built a budget for hand demolition with each material isolated for
recycling. It is easier to do than 10 years ago as there are homes for
materials but still not easy. The end budget was still roughly about 20%
more than the cut and slash and that cost is borne by the overall budget for
the replacement building - which is how it should be. The kicker is that the
building was a conventional old building nailed together with very distinct
(however inefficient) layers. It made me realize I specify too many screws.

 

Hard to know what to do but I do hope that humankind endures long enough to
figure out how to recycle well and will forgive me for the glue and screw.
The only really good news is that given the economy we will be building less
and perhaps talking about it more.

John makes excellent points based on experience and well considered
rationale.  However, it occurs to  me that there is one advantage of
mechanically fastening the floor assembly, which is disassembly and reuse at
some time in the future.

that is, if mankind endures beyond the tenure of the building.
