Flooring for a passive solar
I am building a home that will use a combination of a mini-split and passive solar in the Pacific Northwest. For thermal mass it has a concrete slab floor with insulation underneath.
My question is about flooring. I was planning on an engineered wood floor but my builder pointed out that this would prevent the sun from heating the slab. He suggests a stained concrete floor or tile. I really do not like either of these options.
How bad is a wood floor? Would a Terrazzo type floor using recycled glass such as Enviroglass be a good option?
