SPFA Release new TechDocs and TechTips for 2020

January 28, 2020

The Spray Polyurethane Foam Alliance (SPFA) Building Envelope Committee (BEC) has developed and published several new TechDocs and TechTips in 2019.

Nearly two years ago, the BEC decided to reorganize and update the TechDocs related to below-grade applications of SPF insulation. Starting with SPFA-140 “Spray Polyurethane Foam for Exterior Subgrade Thermal and Moisture Protection”, the BEC published an update in early 2019. This document focuses on the application of closed-cell SPF insulation on the exterior side of below-grade walls. In 2019 the BEC also developed two new TechDocs addressing the application of SPF insulation on the interior side of below-grade walls and SPF insulation below sub-grade concrete slabs.

SPFA-152 “Spray Polyurethane Foam Insulation for the Interior of Basement and Crawlspace Walls” provides contractors and design professionals with important details regarding installation of SPF on the inside of crawlspace and basement walls, including best practices for insulating and air sealing the foundation-framing interface. SPFA-153 “Spray Polyurethane Foam Insulation for Below-Slab Applications” includes best practices for using closed-cell SPF prior to the installation of sub-grade concrete slabs. Details include addressing proper drainage and soil gas control using SPF.      

With the update to SPFA-140 and publication of SPFA-152 and 153, contractors and design professionals now have a complete series of best-practice documents for the application of SPF on all subgrade building assemblies. All of these documents can be downloaded from the SPFA website here: http://www.sprayfoam.org/technical/spfa-technical-documents

The SPFA BEC has also published three new TechTips for 2019.

  • TT-I-5 SPF Adhesion to Engineered Wood Products
  • TT-I-6 SPF Application over Wire and Plastic Pipes
  • TT-I-7 High-Lift Closed-Cell SPF Insulations

TT-I-5 was developed using data from an SPFA-funded study that evaluated several commonly used methods to improve SPF adhesion to LVL and I-joists used in wood frame construction. TT-I-6 provides contractors with application guidance to avoid exothermic damage to insulated wires and plastic piping. TT-I-7 provides information on new high-lift closed-cell foams to avoid potential dimensional stability problems. All three TechTips can be downloaded from the SPFA website here: http://www.sprayfoam.org/technical/spfa-tech-tips
