Last year, Icynene ruffled energy experts feathers by waging a spirited (and successful) lobbying campaign to defeat a widely supported effort (the so-called Thirty Percent Solution) to raise the stringency of insulation requirements in the International Residential Code.
The solution to this problem is better code enforcement, however not lowering the bar so that violators of one code provision can perform just as poorly as violators of a totally different code provision.
To match the poor performance of leaky fiberglass-insulated homes, all an Icynene contractor has to do is skimp on insulation thickness.
No, Thank you, your email address will not be shared and your privacy will be protected.All joints, seams and penetrations.Of open-cell spray foam (equivalent to about R-20).That just about covers it, doesnt it?Please, enter a valid value, incorrect values!Dereliction of duty, its time for building officials to enforce the code as written.Icynenes bizarre campaign against thick insulation is the second controversial move by the Canadian company.On a day like today when the fiberglass guys do not have to seal up their house, all Im well planned gal coupon code doing is following the practice in the marketplace.Presumably, the letter is intended to convince a local code official that Icynene is so good that theres nothing wrong with skimping on R-value.Many energy-efficiency experts are frustrated that the code is unevenly enforced.The intent of the code is clear: every new home must be sealed against air leakage and must meet minimum insulation requirements.
Its time to stand up for R-38.Many fiberglass-insulated houses dont meet air-sealing requirements so we think its only fair that Icynene-insulated houses be allowed to cut corners when it comes to minimum insulation requirements.Last weeks blog: Blower Door Basics.Common walls between dwelling units.In the 2006 International Residential Code (IRC air-sealing requirements can be found in section N1102.4.That means that new homes, whether insulated with fiberglass batts or Icynene, must meet both air-sealing requirements and minimum insulation requirements.Surprisingly, Icynene is trying to convince builders to install less insulation than the code requires.Walls and ceilings separating the garage from conditioned spaces.
Icynene has seized on this fact the fact that lax code enforcement has encouraged the proliferation of leaky homes to put forth the surprising proposition that Icynene-insulated homes can perform poorly, too.
Building inspectors rarely check airtightness, unfortunately, the requirements of Section N1102.4 are rarely enforced, and as a result, many new American homes especially fiberglass-insulated homes perform poorly.
