On several occasions, I have mentioned the need for products that are innovative, green and affordable. In Las Vegas, I spent a great deal of time seeking out products that meet these criteria. As part of my continuing efforts to share green methods with the world, product reviews will become an vital part of this blog moving forward. So, the lucky winner of the first review is….
Fi-Foil Company: Radiant Insulation Solutions
In Las Vegas, I had the pleasure of meeting Tim with Fi-Foil. The one product that stood out was Flash & FOIL frame wall insulation with VR Plus Shield. This is a unique product that combines with spray foam insulation to provide a high r-value in normal 2x4 construction wall.
As a builder and purchasing manager, I reviewed pricing for spray foam insulation on a number of occasions. Each time, the benefits of spray foam were far out-weighed by dramatic increase in cost. In addition to the cost, filling wall cavities with foam makes repairs to electrical, plumbing and any other product contain in those walls a little more challenging. Thus enters a revised system.
This system consists of 2-½” of spray foam combined with the VR Plus Shield. VR plus shield is a multi-layer foil product with a paper face which, when applied to the studs, separates allowing air to pass between the layers contributing the insulative properties of the product. This system allows wiring and plumbing to be installed so as to not be covered in foam. It also reduces the quantity of foam required replacing it with a less expensive, more effective product.
So, Fi-Foil makes a great insulation product that increase energy efficiency, improves indoor air quality and reduces the cost of installation. Find more information on their website at: http://www.fifoil.com/

Green Your Home – Crawl Space & Attic (Part 3)
On Monday, I inspected my crawlspace because of a mouse problem. When I was in the crawl space, I found an incomplete repair of the HVAC system. From the builder, I learned after closing there had been a problem with a duck in the crawlspace that died in the ductwork and was eventually removed and damaged items were “repaired”. When I did the inspection for the mouse problem, I found uncorrected damage, pictured here.
So, with a couple of assistants out of school for the week (my 7 and 5 year olds), we took our supplies and went under the house. Upon further inspection and preparation, we also found a disconnected duct to the utility room, an area always difficult to heat and cool since it was not getting any air. So, we set to work on the two repairs. First the hole, then the disconnected duct.
To fix the hole in the trunk line, I began by covering the entire hole with foil tape (UL 181 tape, the same type used for Energy Star Homes). With the hole covered, I wrapped the trunk line, including a previous repair, with duct insulation and completed with foil tape to secure it to the trunk line and seal off any holes/leaks.
The disconnected
duct was easily repaired as well. After cutting the end of each line, the two ends fit more closely together. With the foil tape and a little maneuvering, the two lines came nicely together. As I was completing the repair, the air turned on in the house and I was able to check the reconnected line for leaks. While chec
king, I noticed several other ducts where the duct tape had deteriorated enough to allow air to freely flow from the seams. I resealed those with foil tape as well (if I had mastic – a sticky sealant that will seal the lines air tight – it would have been an easier fix).
After a few more tests and cleanup below the house, the crawlspace was as good as new and will be a little cooler next time I go down there.
I also completed the insulating foam on the attic stair. This will reduce the amount of air loss around this opening.
Next article will discuss indoor sealing techniques.

Green Your Home – Preparation (Part 2)
The list is complete, so it is time for a trip to my local Home Depot. I spent about an hour at the store recording items, alternatives, costs, etc. I quickly found that with less than $100 I could do most of the work that needs to be done on my home. You can also do your shopping online, if you so desire, to save the time driving to and walking around the store, although some items are not available online at HomeDepot.com.
The items I purchased are as follows:
• Great Stuff Gaps & Cracks – This is expanding foam that can be used in any openings, holes, and cracks in the exterior shell of you home. Be careful where you us it because it will expand. Great Stuff should not be used around window frames, as it will affect the opening and closing of windows by pushing on the frame. This is great for any holes not filled in from electrical or plumbing lines entering the crawl space, garage or attic. [Price: $4.98/can]
• Caulking & Sealants – I found two products I like for this. DAP makes an
Elastomeric Latex sealant which will stretch with the moving and settling of you home. [Price: $3.37/Tube] You can also purchase GE Silicone II Window & Door. es the peace of mind it is silicone. Personally, I prefer latex because it is easier to paint after it dries. I buy this p rod uct by the case and use it for a number of projects around the house.
• Rubber Foam Weatherseal – It comes in a number of sizes depending on the application (I purchased ¾”x5/16”x10’). This can be used to seal any doors, whether to unconditioned space or an unused room/closet which will not be heated. Simply apply to the frame where the door will close and you have a better seal against airflow. [Price: $2.88]
• Replacement Door Seals – Most entry doors have weatherstipping that can be removed and replaced. This product will breakdown overtime allowing both air and, eventually, little critters (bugs and spider) easy access to your home. [Price: 3.99/strip]
• Replacement Door Sweep – This product attaches to the bottom of your door and serves a similar purpose as the above Door Seals. Many types are available. If you know the slot configuration on the bottom of your door you can purchase a door specific replacement to match your current sweep.
• Duct Insulation – For un-insulated or damaged insulation, you can install new insulation very easily, provided you have access to the ducts. Several versions are available (I purchased foil faced 12”x2”x15’). I recommend foil faced as it provides the best insulated value. [Price: $10.97] 
• UL181 Duct Tape – Different from typical duct tape, this is a foil tape specially designed to not breakdown overtime, or with heat/cold, as typical duct tape will. This product is used to seal any seams, gaps or tears in duct lines. [Price: $14.75/Roll]
• Air Filters – Replacement filters are important to the overall performance of your system. I will not go into great detail here as filters can be a discussion all of there own.
Your overall cost will vary depending on how much you purchase and what you need for your home. The associates at Home Depot were very helpful, so when in doubt ask for assistance.
Now the work can begin. Stay tuned as I bring you pictures, tips and tricks to using these products effectively in Greening your Home.
