Getting It Done the Right Way

Below is our team of experts’ top three tips for ensuring that your SPF jobs get done right, the first time around:

  1. Get the ratio right. Two-part SPF formulations require the right ratio of the “A” and “B” components for a proper chemical reaction to occur. As a result, the insulation needs to be good quality. There are numerous variables that can affect the ratio and the mix—all of which can be addressed with the right equipment. SPF rigs can be outfitted with a “fault-interruption ratio” (when the mix goes off ratio, the rig shuts down) and a temperature monitor.
  2. Watch the lift thickness. A lift is a single layer of foam, sprayed in one pass. Each SPF product should be installed at the specific lift thickness recommended by the manufacturer. Most recommend or require lifts no greater than 1.5 to 2 inches. In closed-cell spray-foam installations, if the lift is too thick, the heat generated by the chemical reaction that forms the foam can result in chemical decomposition – or even ignition. With open-cell spray foams, there are typically no heat-of-reaction issues, but the expansion rate can result in the formation of large gaps in certain types of open-cell foam, impacting the material’s R-value.
  3. Get the substrate right. The temperature of the substrate is an especially big deal in winter installations; really cold substrates can pull enough heat out of the reaction that the SPF doesn’t expand properly or bond to the substrate adequately. And substrates that are too hot can also cause quality issues.
