Insulation Guidelines for Foam-in-place Insulation
By Masonry
The following is a checklist of items and/or procedures to watch for when inspecting an application of foamed-in-place insulation. All of these items are covered in the standard installer certification program — a program required of all licensed foamed-in-place insulation contractors.
- A copy of the foamed-in-place insulation Material Safety Data Sheet should be on all foaming trucks.
- Foamed-in-place insulation is to be applied to closed cavities where it is not left open or exposed. In residential applications, an interior wall vapor barrier should cover it.
- Verify the foamed-in-place insulation product label with a batch number. Be sure the material has not passed the expiration date.
- Ask to see the installer's identification card. Verify that his training date is current. Determine the installer's identity by looking at the picture on the card.
- Ask to see the sample of the material saved in the QC "container."
- Make sure the date, weight, material batch number, installer's name, and job address are all clearly marked on the sample container.
- Make sure the weight recorded falls within the parameters of foamed-in-place insulation weight standards for freshly foamed material.
- Verify that there is a gram scale in the truck or on the jobsite.
- Make sure there is a vapor barrier installed on the inside surface of any residential wall cavities.
- Request that the applicator foams a sample to show you the setting time is as described in the manual.
- In extremely hot or cold temperatures, determine that the material in the barrels is kept within a temperature range of 55 degrees to 80 degrees Fahrenheit.
