The Best Spray Foam Kits for Insulating a House

Froth-Pak 210 Fire-Rated Insulation Kit by Dow Chemical Co.

If you’ve never used a spray foam insulation kit before, then you should definitely get the Froth-Pak 210 Kit on Amazon here. It has very high customer reviews and very few complaints.

It’s very easy to use with the spray nozzle. It also includes ten different tips to try out, including six fan tips and four con tips to figure out which one is the best for your home.

The ‘210’ in the description of this product refers to the fact that it covers 210 sq. ft. of an area with one inch of foam. Spray it evenly back and forth to get the most out of it. You should never aim a spray nozzle directly at a single area for too long.

One of the most notable features of this foam insulation is that it’s moisture-resistant. You won’t have to deal with mold growing all over it, unlike insulation batts and other types. It also has a chemically-cured formula to expand and dry quickly.

Pros

  • Comes with enough foam to cover 210 square feet with 1-inch thick foam
  • Easy for beginners to use
  • Moisture resistance to prevent mold and bacterial growth
  • Includes ten different nozzle tips

Foam It 202 Fire Retardant Spray Foam Insulation Kit

https://www.youtube.com/watch?v=6-u6phkLgSA

Next up on the list is the Foam it 202 Fire Retardant Spray Foam Insulation Kit. This pack covers 202 sq. ft. with a 1-inch thick layer of high-quality insulation. It also comes with safety gloves, a handful of adjustable tips to change the spray style, and coupons to save money on your next purchase with the company.

This foam insulation expands to create a seamless barrier that’s airtight and watertight. It has a green tint to show you exactly where you’re spraying it, rather than blending in with the surface that you’re using it on. The barrier also prevents mold from growing, much like the previous entry on the list.

The total R-value of this insulation foam is 7, which is much higher than the vast majority of spray foams on the market. Many customers have used it to insulate houses, campervans, and other enclosures.

Pros

  • Includes gloves and numerous tips to change the nozzle spray pattern
  • It comes with 202 sq. ft. of spray foam insulation
  • Has an R-value of 7
  • The green coloring distinguishes the foam from everything around it
  • Mold resistant!

DOW FROTH-PAK 620 Spray Foam Sealant Kit

If you’re working on a big project, such as an attic or a garage, then the Dow Froth-Pak 620 Spray Foam Sealant Kit is the way to go. Given the name, you’ll notice that it has enough insulation to cover 620 sq. ft. with high-quality insulation foam. Perhaps the most impressive trait is that it cures in under one minute.

The two-part formula used in this insulation foam works to expand and harden quickly, but it also forms a moisture and air barrier to maintain the interior temperature of the area. Whether you’re fixing a small corner of a crawl space or a massive room, this solution is an excellent choice for all buyers.

If you decide to buy this kit, you’ll also receive a petroleum jelly packet, a small wrench, 12 nozzles (8 cone-style and 4 fan-style nozzles), as well as a 15-foot hose. A thin layer of skin begins to form in under 40 seconds, creating an insulation barrier right away.

Pros

  • Comes with everything you need to get the job finished on time
  • Quick curing process
  • More than enough insulation to cover over 600 square feet of space
  • Maintains interior temperature and prevents mold from growing

Foam Kit 110

 Last but certainly not least is the Foam Kit 110 by Touch ‘n’ Seal. This top-tier pack is designed for small areas, such as tiny sheds, crawl spaces, patch jobs, and so on. It comes with a pre-connected 10’ hose that gives you enough range to move around without feeling limited or tethered to the box.

The gun is made to prevent a cross-over of the chemicals by using two separate tubes. The mixture combines as you squeeze the trigger, creating a new bond that hardens in minutes. It expands up to 30 times larger than the original liquid, so make sure that you don’t spray too much at a time.

Another great feature of this spray foam is that it already has everything set up as it arrives. You don’t have to hook up the hose as mentioned earlier, but the two bottles are already upside down as well. Rather than manually mixing and applying the foam, you only have to point and shoot right out of the case.

Pros

  • Quick and easy setup process
  • Applies in seconds; Dries in under a minute
  • Includes a 10’ hose and additional nozzles
  • Perfect amount for small spaces; Save money by using less

How to Use Spray Foam Insulation

You can either have professionals do the installation, or you could save money by applying the spray foam insulation by yourself. If you DIY the project, follow the suggestions below to have the best chance of success.

  1. Wear head-to-toe protection. Spray foam contains toxins before it hardens, not to mention that you don’t want to breathe it in. Put on gloves, safety goggles, a breathing mask, and long sleeve clothing.
  2. Dry off all surfaces that you intend to spray the foam. Otherwise, it won’t stay in place.
  3. Cover windows and other areas that you don’t want to get insulation foam on.
  4. Start by spraying the outside areas of the portion that you’re insulating. Slowly spiral inwards to ensure an even coating.
  5. Once it’s thoroughly dried, use a curry comb to remove excess foam bits that stick out.
  6. Ventilate after you apply the foam for an hour afterwards to remove any fumes and make the area safe.

You also need to keep in mind that you’ll have to replace the nozzle every time you stop using the sprayer for 30 seconds or more. The foam hardens, making it impossible to spray. You’ll also need to use the petroleum jelly packet to lube the nozzle when you replace it to prevent the foam from drying right away.

Takeaways

Department of Energy

Spray foam insulation is easy, convenient, and affordable. Whether you’re a DIYer or someone who loves an efficient job well done, foam is almost always the way to go. Don’t forget to wear safety gear and follow the steps mentioned above.

Here are a few takeaways:

  • Safety – Wear a respirator, gloves and suit to protect yourself from the foam and fumes. Also, ventilate the area to remove any of the fumes afterwards.
  • Prep work: Have a clean and dry area for the foam to attach.
  • SQ FT – Make sure you have a good idea of the actual sq ft area that you plan on insulating. It is best to buy more foam than you need or else you will run out. It is better to have more than enough.
  • Directions: don’t stop and forget to clean off the tip and turn off the tanks.
