Started Oct 19, 2015 0 Replies

I have been a big fan of National Fiber's Cel-pak cellulose since about 2008. Located in Belchertown, Massachusetts, National Fiber made one cellulose insulation product, named Cel-Pak. It contained…Continue

Brad Cook replied to Luis Hernandez's discussion Vapor Barrier on top of basement concrete floor
"An appropriate type and thickness of XPS rigid insulation will be a vapor barrier (check the perm rating for your local products). If the seams and perimeter are sealed, and especially if the XPS is glued to the concrete, you will have a vapor…"

Brad Cook replied to Rob Buchanan's discussion High-use headscratcher
"To give some perspective, at 11,568 KwH per month, that would be 16.07 KwH per HOUR, or 67 AMPS at 240 VAC (134 amps at 120 VAC) running 24/7. Yes, that is HUGE for the situation described. Put an amp meter on those circuit breakers. A 1 HP…"

Cellulose insulation is not all the same

I have been a big fan of National Fiber's Cel-pak cellulose since about 2008. Located in Belchertown, Massachusetts, National Fiber made one cellulose insulation product, named Cel-Pak. It contained about 85% chopped up newspapers, primarily from overruns (a very clean newsprint), with Borate as a fire retardant and a little mineral oil for dust control. Last year some yahoos bought Greenfiber and then bought National Fiber. Last month, they closed the Belchertown plant, so Cel-Pak is not…See More

"But the good news is that lower fuel prices: will free up more $$ for the lower and middle class to spend on important things and help the economy will create a disincentive for the Keystone Pipeline and Hydrofracting it might free up enough money…"

Brad Cook replied to John Shillito's discussion Fixing a water heater?
"A common cause that I have seen is undersized gas supply piping, especially when a combustion appliance is added to the line. Undersized gas supply pipe = lower gas pressure => high CO"

Brad Cook replied to Patrick Michaelyan's discussion Closed-Cell Foam & Brick Walls
"Here in central Vermont, we see houses from the 1800s with brick walls as part of the foundation, but the brick is not structural. Large slabs of granite are holding up the typical 8x8 sill beam. If we were to spray SPF (Spray Polyurethane Foam) on…"

Brad Cook replied to Mike Rogers's discussion Where do you fall in the "staged" versus "gotta be all at once" discussion?
"I would argue that ALL projects are "staged", unless it is a NetZero project. There will always be room for improvement. Let's look at projects as degrees of comprehensiveness. On a scale of 1-10, with 1 representing a little air…"

Brad Cook replied to Kim Tanner's discussion Long term average
"When the wind is breezy, I use long term averaging. The more the pressure jumps around due to breezes, the longer the term that I use. Even then, I mentally average the readings. This is after I have taken steps to shield the end of the outside hose…"

Brad Cook replied to James Murray's discussion Water Water Everywhere
"Walk away. To be blunt, in my opinion, if you are asking these questions on this project, you should be starting with less complicated jobs. Manufactured homes are not the same as stick built, although there are similarities. The bathroom vent fans…"

Brad Cook replied to Bud Poll's discussion Calculating attic ventilation
"Everything that I have read on the subject agrees with what John Nicholas presented. What appears to be a big misconception by many people is that we ventilate a roof to make it "cold" to minimize ice dams. The real reason is that the…"
