A Sturdy Subfloor


Bill found a 1 1/8" thick tongue and groove plywood made by Georgia Pacific which will meet code to span the 35"on center gaps between Christian's old trunk/beams that support the dining room floor. These 1780's floor beams are oak tree trunks made flat on top and are in remarkably great shape. The old floor here wasn't, so I located these (rare here) sub-floor boards from a left-over lot in PA since we just need nine of them. Each 4' X 8' board made in Oregon weighs 99 lbs., and they ship free to a NJ branch and then here in four days.

The earlier image above shows the tree trunk beams best, which had bark still in some spots while all were inches away from solid clay ground.

Installing a New Air Handler and Ducts


Christan has hired Stellitano Heating and Air Conditioning to install a new air handler and duct work to complete his heating system. They are absolutely the best in our area and we have watched them grow from a few to a fleet of hard to miss red trucks with great logos and a terrific team of workers... over the years.

Initially Gary Stellitano (owner) surveyed the house with advice and then returned to critique the boiler system Bill and Christian built. Last week in record breaking cold weather, we made a few revisions and are now ready for the red trucks and some team work! Luckily the single digit temperatures disappeared the day they arrived, and the air handler is being fit into the new crawl space Christian created.


My job as "gopher" has been to pick-up bales of insulation and find tools like a vintage Ridgid pipe threader on craigslist; while Christian has run his wood stove, installed insulation, and brought space heaters from home and work to keep the water now in pipelines from freezing. Bill remains our driving force.

Roxul Vs. Fiberglass Vs. Foam Insulation


The upstairs bathrooms and ceilings in Christian's old farmhouse are being insulated with "Roxul" insulation bats made for either ceilings or walls, which have "R" values of 23 and 15; respectively. The largest room will accommodate two layers of R15 in the ceiling which will well insulate the main part of the oldest structure of the house. This insulation is made of lava-type stone making it fire and water/mold resistant while deadening sounds - which is all perfect for Christian's locations. Fiberglass is a bit less expensive, but the difference felt in a completed room is remarkable while the installation of "Roxul" dense bats (cut with a bread knife), is easy and less irritating. 


The R value per inch for fiberglass insulation is 3.14, Roxul is 4.1, and closed cell foam would be around 5 for the rafter depth we have here. An install of 5" thick closed cell foam in the open ceilings of Christian's old farmhouse cost $3,000; however a partial house install does not work with this product. Spraying foam on old wooden beams, floor boards and electrical wiring seems wrong and too expensive for us besides. Single cell foam would be $2,000 for the same areas with the same issues and an R value of 3.7 per inch.

Five of the upstairs rooms in this farmhouse have had their plaster ceilings removed and recessed lights as well as fans in the bathrooms have been installed. Two layers of Roxul 2" X 4" insulation bats have been installed in two ceilings, with single layers of 2" X 6" bats in the others.

The main bathroom above, had Roxul Safe & Sound also installed in the tub surround area which sound proofs the space from the adjoining guest bedroom.


Update: Below are the finished rooms...

Planning the Master Bathroom


Christian's master bathroom will have hydronic floor heat feeding a new cast iron floor radiator in the adjoining dressing room which is not usual, but both rooms are furthest from the boiler and the latter has one hot air duct we are supplementing. New "Ruxul" insulation made in Canada will be installed here as well which is superior in R value, non flamable and sound deadening.


The PEX lines will again run 6" apart which is terrific in a bathroom floor as opposed to the usual 8" span.




Christian has rewired the main wall here (and room) to allow for a mirrored medicine cabinet, double wall sconces for maximum lighting, a recessed shower light, and ceiling exhaust fan. 


Early on, the sub-floor was removed to replace the toilet connection with a taller pipe...
