I don't think I got the full 40 mil depth that they recommend, but I'm pretty happy with it. I did two coats of ceramic on the walls and ceiling, but only one coat on the floor. For example, I did two coats of sound deadener on the floor and the larger sections of metal. I decided to get 6 gallons of each and prioritize the areas that I thought needed it most. (Ceiling = 66 sq ft, side walls (not including windows) = 99 sq ft, floor = 66 sq ft, back doors and cab area = ~ 54 sq ft). After doing my own research I decided on the following insulation plan:Ĥ) 1/4" cross linked polyethylene between all finish wall panels and frame (the places not covered by Thinsulate)Īccording to the Lizard Skin website, I needed 12 gallons of ceramic and 12 gallons of sound deadener to do two coats of each. I am at the beginning of my build and also learned about Lizard Skin from Ken's videos (thanks again, Ken!). I live in a place that is commonly over 100-deg in the summer, so I will take all the help I can get. The shaded area under the solar panels stays cooler much longer with the Lizard Skin in place. The ceramic particles slow the transfer of heat, making the steel less efficient at heat transfer. Steel is a very efficient conductor of heat, so the heat was flowing from the hot exposed metal to the cooler shaded part. Another hour or so after that and it was nearly as hot as the exposed metal. Another hour later and the steel under the solar panel (always shaded) was starting to warm. Under the solar panel the steel was cool. An hour after the sun is up the portion of the ceiling in direct sun was so hot I couldn't leave my hand on it. As an example, my solar panel covers much of my roof (40"x 65"). It wasn't an easy decision since I had to tear my van apart to do it, so I spent a lot of time measuring and observing heat gain in the van prior to having any insulation installed. I'm happy I did it and the difference in heat gain is noticeable. Just doing the ceiling alone would help versus nothing at all. Starting over today with a bare van it's one of the first things I would do. Keep in mind I did not do this when my van was bare and brand new, so compromises had to be made. The same day we used 2 gals to spray the ceiling and entire walls of my friend's 144, although like mine we skipped the sliding door. Specifically, my van took 1.5 gal to do the entire ceiling and walls, except I did not spray below window level (cabinetry in place), did not spray the floor and did not spray the sliding door or rear door for fear of mucking up sensors, cables, latches, etc. Lizard Skin has a calculator on their website, and assuming a 144 van is about 50 sq ft (not sure on that), it states 2 gal. Around 2 gallons will get you the correct depth on a 144 Sprinter. See a video tutorial on LizardSkin application at think your conversion from sq ft to linear feet might be incorrect. LizardSkin also tosses in a mil gauge to ensure the optimal coverage thickness. It includes the spray gun (which connects to a shop air system), plus a quart cup and a drill-driven stir paddle. Use LizardSkin’s SuperPro application kit to properly apply the coatings. LizardSkin has a handy application calculator on its website. One two gallon container will cover about 40-45 square feet at 40 mils thick. The coating will also enhance interior cabin acoustics, making it a perfect complement to high-end audio systems. LizardSkin Sound Control is an effective way to combat annoying rattles, vibrations, and road noise. Two gallons will cover 45-50 square feet at 40 mils thick. The composition sprays easily in one step-additional coats are not necessary. LizardSkin Ceramic Thermal Insulation Coating will squash excess heat in racecars, street rods, trucks, and virtually anywhere cabin heat is a problem. They’re available in one and two gallon containers. Both water-based coatings are class-A fire rated. In addition to the thermal and acoustic benefits, these coatings create a tough, seamless moisture barrier to prevent corrosion. Lizardskin is an environmentally friendly way reduce, heat, noise, and vibration from entering the vehicle's interior-testing showed that applying LizardSkincan reduce heat transfer by up to 30 degrees, and sound transfer mitigated by up to 12 dB. Summit Racing now carries Lizardskin Sound and Thermal Insulation products.
