How To Insulate Wall Cavities With PolyTech Polyurethane Portable Spray Foam Kits

There are older houses in the nation that are not insulated at all. Without the existence of reasonable insulations, heat or cooling generated inside the house flows to the exterior ambients continuously. This creates problems for old houses that exist in locations with severe winters and summers. With rising energy costs, monetary and natural resources wastage is significant. The PolyTech two-component polyurethane foam presents an ideal solution. Each inch of cured foam has an R-value of over 7.30. The foam kits are self contained. All necessary tools and accessories are included with the kit. The end user can initiated the project by simply connect the dual hoses to the Resin-A and Resin-B cylinders. The mixed resins expand and cure rapidly in any cavity. The two pound density foam is light in weight, yet the thermo insulation value is high. Removal of existing drywall is not required A rough guideline for insulating wall cavity with spray foam:

1. Walls are supported by studs that are spaced 16" apart at dead center. The following application is based on the assumption of a 8 feet ceiling height.
2. Bore three(3) vertical 3/8" diameter holes along a wall section between the 16" spacing studs. The holes are 28" apart vertically, with the lowest hole 36" from the floor.
3. The holes are bored at a 45 degree downward angle.
4. Connect the dual hoses of the kit to the Resin-A and Resin-B cylinder. Turn both cylinders fully on.
5. Shoot the foam resin into the lowest hole for 3 seconds.
6. Wait 30 seconds. If foam does not expand to the level of the lowest hole, inject foam resin into the same hole for an additional 3 seconds.
7. Step 5 and 6 will indicate how long will it take to inject enough resin to fill the section of cavity completely without over filling.
8. Repeat steps 5, 6 and 7 for the middle hole and then the top hole. 9) Execute the same procedure for wall sections that needed to be insulated.
