Abbreviated Tech Tips

Maintain Adequate SPF Temperature in the Cold:In cold weather it is important to maintain adequate SPF material temperature to insure proper metering and mixing of the A and B components. One way of accomplishing this is by a process of recirculation. First, turn the preheaters and hose heat on. Next, use the transfer pumps (do not engage proportioner) to circulate the material through the preheaters and heated hoses, and then back into appropriate drums. This process will raise the liquid material temperature quickly and uniformly. Care should be taken to prevent excess moi sture or humidity from entering the system during this process or contamination can occur.

Spray Polyurethane Foam and Open-Combustion Appliances

Before applying SPF( spra y foam polyurethane ) insulation in an attic or c rawl space it is important to determine if there are any appliances present, su ch as a water heater or a furnace, that are open - combustion and require a source of combustion air .

SPRAYING POLYURETHANE FOAM TO CPVC PIPES

As a result of two separate and extensive studies, the proper application of sprayed polyurethane foam, both open and closed cell, is not an issue from either a chemical compatibility or exposure to exothermic heat during or after the foaming process.

Flood Resistant Construction Report

The 2017 U.S. hurricane season, the worst in more than a decade, has taken its toll on millions living in the southeastern US. It is not only the destructive winds, but the flooding caused by rain and storm surge that has damaged tens of thousands of homes. While these recent events are well documented, floods can occur in all regions of the US, and a significant number of homes may be vulnerable to flooding. Floodwater damage is very different from rainwater or domestic water supply leaks. Floods are typically categorized as by: coastal floods from storm surge, river floods (fluvial) and surface floods from high rain levels (pluvial). Each category of flood water brings with it potentially dangerous corrosive materials and/or bio-hazards including sewage, fuel oils, chemicals from the lawn and street and possibly other hazardous materials from miles away.
