Van Insulated with Kraken Fast Coat Spray Foam Insulation Can

Step-1: Assess & Plan Your Needs

The first step is to determine the areas that require insulation. Insulate the wall, ceiling, and floor with spray foam. However, there are instances where you use a protective coating on the van floor in place of spray foam. Then, consider the climate and the amount of spray foam insulation. 

Step-2: Clear & Clean the Van

Ensure the van is clean. Remove any unnecessary items, debris, or existing insulating materials that can obstruct the new insulation. This step also involves removing the seats or bedding in the van's cargo area.  Clean the insulation surfaces from dust, moisture, dirt, and grease.

Step-3 Prepare Insulation Area 

The main focus for van insulation should be the cargo area. Prepare the insulation area by demarcating the front seats from the cargo area. The spray foam must be applied directly to the metal, so removing any paneling on the walls, floors, or ceilings of the van is important. Use plastic sheeting or tape to create the demarcation. In addition, cover and protect areas such as windows, doors, electrical components, and fixtures. 

Step-4 Choose the Right Spray Foam Insulation

Use high-quality spray foam products to guarantee effective van insulation. We recommend using Kraken Bond FastCoat Spray Foam product for all types of cargo van insulation. It is a premium Spray foam product with high adhesion formula, low expansion, and excellent thermal resistance. FastCoat Spray is a closed-cell spray foam with an R-value of 5.66 that will create a tight seal in your cargo van, camper, or sprinter. 

Step-5: Gather Materials & Tools

Gather the necessary materials and tools required for the insulation process. You will need a foam gun to aim and apply spray product efficiently, a utility knife, gloves, goggles, and other protective clothing. 

Step-6: Apply the Spray Foam Insulation

To apply spray foam on your van, start with the ceiling. After insulating the ceiling, then the walls, and lastly, the floor. For the walls, apply the foam 12” - 18” away from it in vertical applications. Then for ceilings, apply spray foam at a distance of 6 - 8” in horizontal positions. Avoid applying too much foam at a spot. The application should be even across the wall, ceiling, and floor of the van.

Fill gaps, cracks, and cavities with the spray foam, ensuring complete coverage and an even insulation layer. Pay close attention to corners, seams, and areas prone to heat loss or air leakage. The same spray foam application process applies to cargo, sprinter, and camper van insulation.

Step-7: Trim Excess Foam 

As the foam expands, use a utility knife to trim off excess foam to give a smooth and even finish.

Step-8: Wait for the foam to Cure 

Allow the foam to dry and cure properly according to the manufacturer's instructions. Kraken FastCoat requires a curing time of at least 24 hours.  

Step-9: Inspect Sealing and Insulating Gaps

After the curing, check for missed spots and apply foam. Also, inspect and seal gaps properly.

Step 10: Finishing Touches

After applying insulation, add finishing touches to cover the foam. There are different finishing touches, such as paneling or fixtures, that can make your van conversion look neat.
