Have taken on quite a project. Trying to create 2 walls around our bed in our loft that will allow as much light and air in as possible, yet give us somewhat of a sound barrier, when one of us is in the bdrm and the other is outside of it, walking on our old squeaky floors or watching TV.
Want the look of the 60's sliding glass/or plexiglass floor to ceiling doors (see attached jpg sketch). Need help in choosing materials to use, how to install, and trying to come in at or under $4000 including installation. (two probs: (1)overhead pipes necessitating a header, soffitt, & transom next to it and (2)construction of corner between the two walls),
Is the wall load bearing? Need to know in order to figure what you will need for a header.
-For sound proofing, do a search for sheetrock with a db rating. Installed properly some of the new products have excellent results---at a price.
For your patio doors, Anderson has doors that come in kits however their threshold/sill sticks up 2.25" from the base which can cause a tripping hazard unless you can build the floor up. Pella has great wood patio doors however the come pre-assembled. I regards to price, you might end up better off using a stock 6' door and ordering a 3' sidelight. Sometimes a 5' + 9' special order doors can add to the price. However you might be able to fit a 60"x80" door on your elevator if you can fit a 96" piece of sheetrock.
