Martin, I would not call your web site put up "reporting". Your significantly strident "musings" are sensationalistic, deliberately deprecating to Individuals you disagree with, use scientific information and mathematical formulations selectively, include things like conclusions not supported by your possess evidence, and appear to therapeutic massage the facts to suit a predetermined summary.
Garage door reinforcement struts Participate in an essential purpose in keeping sections straight during operation.
Thanks for your response. Perhaps what is complicated to me, not less than, is the "shiny area" which not simply reflects light-weight, but will also reflects heat. The inside of my portable kerosene heater, as an example, contains a chrome backing which displays the heat within the kerosene burner in direction of the entrance Considerably like a shiny steel roof demonstrates heat through the Sunlight again into the sky.
Thank you, thanks, thanks! That is a subject matter which has been haunting me for numerous months. We've got an organization that is inviting senior citizens to lunch and looking to offer them a radiant barrier that they say will Slash their utility expenses (not just heating and cooling, your entire bill) by forty%.
I'm a loyal reader of yours, and of GBA in general, and might not say adequate about the quality of material you fellas present.
Ultra NT Radiant Barrier is actually a large duty radiant barrier sheet produced up of an individual layer of woven polyethylene materials bonded to and sandwiched amongst two very reflective aluminum surfaces.
This is a lot more typical in salty or wet environments. Magnetic ornamental garage door components eliminates these challenges by utilizing solid rare earth magnets for attachment and ABS vinyl that's created to hardly ever rust, chip, peel, or flake.
Is usually a ventilated attic inside a scorching-humid local climate the very best Answer naturally not, but it is healthier that not owning it. Finally, my water heater is likewise from the attic, so 1 side result is sort of no standby warmth decline from your drinking water heater into Spray insulation the attic at 115 degrees:)
Martin, many thanks for your Perception and information. I'd a couple inquiries. my house is in Dallas and I just lately altered out the roof which integrated radiant barrier about the decking. When I measure the decking temp in the summertime its is surprisingly cool even so the roof rafters are surprisingly very hot.
I suppose my order Operating from The within to the outside would in truth be Drywall, XPS the ISO with foil facet dealing with the airspace/back again of sheathing, would it not not?
In case you are burying ducts in blown-in fiberglass, I hope they are 1st insulated with duct insulation Geared up having a vapor barrier. Usually, the ducts will probably be dripping damp throughout the summer season months.
Next, insulation is built better by a radiant barrier. If the insulation in your attic stays cooler, your living Area stays cooler. Also, your AC unit gained’t have to have to work practically as tough to cool it down. Which means decrease Electricity costs and speedier cooling.
The best way to retain your ceiling cool is always to improve the depth of your attic insulation. If your ceiling has become eighty two levels, then your insulation is insufficient. Your ceiling temperature need to be the same as your indoor air temperature.
This is why I routinely set up foil/bubble/foil under an in-flooring radiant heating program 4" with the subfloor. This is probably the two simplest and price-successful sites to work with a radiant barrier. The opposite is beneath the roof in any weather, Except the roof masking is white.
