Starting Jan. 1, all polyiso manufacturers will have transitioned their product testing methodology to more accurately predict thermal performance over a 15-year period. On Dec. 12, Roofing Contractor will host a free webinar that will explore long-term thermal resistance (LTTR) and explain why the test method is changing.

The presenter, Tyler Cooper of Firestone Building Products, will also detail the different R-value standards and explain which one should be used for specifications when bidding projects. We’d like to invite you to join us for “LTTR: Find Out How Changes in Insulation Testing Will Affect Specifications in 2014.”
