I am building a house and I gave the builder the floor plan of house I wanted. I signed off on the plan, not knowing how to read a blueprint, not realizing the builder changed the entrance to the basement from my kitchen to entrance to the basement from my foyer. Also the arch from the foyer was to be wall-to-wall, it looks like an entrance from the foyer.

I have a severe allergy to anything new (carpet, paint, most flooring, etc.). I currently live on the 2nd floor of a 3 story apartment building. I just found out that the tenant above me will be moving out - so the apartment will be painted and prepared for the next tenant. My concern is that the VOC's from the new paint will pass through the flooring into my apartment. Is this something that occurs rapidly almost effortlessly, or something that is rather slow? I really appreciate your time.

I'm working on a project that would be made a million times better if I could embed LED diodes into the EPS that I am using....

I understand that EPS is by nature highly flammable, but seeing as it's used as insulation, I'm wondering if embedding the diodes in it would really be a problem.....

Any insight would be very appreciated...

I am considering having the fiberglass insulation removed from the attic floor and having open-cell foam sprayed in its place. Most foam installers are pushing the idea of sealing my ridge and soffit vents, spraying the underside of the roof and creating a so-called conditioned attic. This is a 2,100 square foot all brick ranch with a 6-12 roof built in 1967. We want to keep the insulation within the 2 X 6 framing as we have much of the attic floor covered with osb. We use it for some light storage.
