Installing Reach Silvertanium Reflective Attic Insulation from Home Depot. This is a Radiant Barrier that reflect 95% of radiant heat and has an E of 5%. www.homedepot.c...
Hey, thanks very much for the video! I've been researching all sorts of options for my very hot attic for the past 4 months, even going so far as getting a quote for a ridge vent install. Radiant heat barriers are a much cheaper initial option to test though. Your video is the only one wherein you show actual visual proof of what a radiant heat barrier is actually doing. Not even the product vendors thought to do such, which would probably greatly increase their sales. I've been looking at the AtticFoil product which seems to be similar at 23# 1000 sqf, however the price is lower, though maybe not with shipping/tax. They also offer 60" width, which is nice. Great video, would love to see a follow-up with more pics or data.
Thank you for the comment. Yes, AtticFoil is about the same. One of my friends used it after I told him about radiant barriers. I think Homedepot does shipping free and AtticFoil charges for shipping so it comes out similar. Ideally you should have both the radiant barrier and some form of ventilation. I am still trying to work out the ventilation because my house was build in 1873 it has issue, but my friend that used the AtticFoil had a fan and found the optimum thing was to turn the thermostat on the fan form 95 down to 85 after putting the radiant barrier in. The problem is that it reflects in both direction so it reduce the high temperature but keeps what heat that does in. With the fan set to 85 it seems to work the best. Let me know how it turns out with your house.
@@yensoftware Thanks for the mention - www.AtticFoil.com A couple of things: We now offer FREE shipping on all orders. And, AtticFoil actually uses pure aluminum foil on the reflective surfaces compared to a vapor applied aluminum or metalized film (MPET). This is important since over time even though the MPET has a "protective coating" it is compromised when the product is perforated. The aluminum layer on AtticFoil is over 200 times thicker than the MPET products. MPET is MUCH cheaper to make and sell, so it's not fair comparison on price.

To date have you noticed effectiveness in the reduction of heat transfer ? I also have been researching this extensively. Looking to see if this is the route I want to take. Thank you
It cost about $166 at HomeDepot for a 4ft x 250ft roll and was shipped to my house ( www.homedepot.com/p/Reach-Barrier-4-ft-x-250-ft-Silvertanium-Reflective-Attic-Insulation-Roll-3023/203536782 ). I do not plan to take it down in the winter. The argument for taking it down would be that it might be nice to get what little warm you can get from the Sun in the winter. However the days are short and the night are long so you would be losing more that you gain so you might as well leave it up. Also it would reflex the heat that gets through your insulation back.

Did you ever do it?
how much was it and would you want to remove in the winter?

Did you measure the peak attic temps before and after the foil installation?
