Rim Joist Project with Lauren and Ashley

If a weatherization specialist came to your home, your rim joist insulation is the first thing he would check. Your rim joist is an easy place for cold air to enter your home. And because of it’s connection to your walls, it easily transfers the cold air right up into the rest of the house.

Sealing and insulating the rim joist (also called sil plate) is quick and easy. The energy savings from having a tight air seal in your rim joist is amazing.

Seal the gaps where your home meets the foundation today. Ideally do 2-3 inches of closed cell Foam it Green - you’ll maximize R-value and stop mold, moisture, bugs, rodents, and cold air.

Start Saving Now

• 1 inch of closed cell Foam it Green gives you a tight air seal and keep air from crawling up your walls.
• 2 inches of closed cell Foam it Green meets r-value requirements in most areas in the U.S.

Project Tips:
Use a drop cloth on the floor to protect areas from any falling “snow” (foam particles)

Spray on Foam it Green so it rises to an inch or two in each cavity. Move to the next cavity and repeat. Once the first coat is cured, repeat with a 2nd coat to achieve the thickness you desire.

Some Customers Who’ve Done it

I used your Spray Foam Product on my basement walls and within the rim joists. I couldn’t believe how easy this was to use. I took me about 1 hour to finish 175 linear feet of space. That’s a fraction of the time it would have taken me if I used rolled up batt insulation.

I received the biggest compliment on the temperature of my basement just this past weekend. A neighbor and I were completing our basements at the same time. He, a former construction contractor, commented on how much warmer my basement was than his. He asked me what kind of insulation I used and when I told him, he was surprised of the effectiveness and warmth it provided. He used styrofoam boards for insulation and in his words, didn’t come close to the effectiveness of spray on foam. From a former contractor’s mouth, that’s quite the compliment.”

I received my kit by UPS 3 days after I ordered. I was very nervous about using the product but after I started I found out how easy it was to use. I have TJI floor joist system and I built my house 8 years ago. With TJI joists the rim is very dense and stays cold in winter. If there is any humidity in the basement you get moisture. With a new tight house you have humidity. This is the only product to properly insulate the rim joist in this application. Anyway, I started taking down the batt insulation at 2pm, my house is 50 feet long so I had 2 runs of 50 feet. I started foaming at 1:45 and was finished at 3:30pm. I started in a store room to get it down first and ended in the family room. With an old rag in hand I did not drip once on the floor, even though my wife prepared the family room floor with old sheets. I will recommend your product to everyone. Thanks, Very satisfied customer.”
