texas911 Posted March 13, 2008 Share Posted March 13, 2008 Is it a fire hazard? Compared, say to fiberglass bat? Link to comment Share on other sites More sharing options...
cgallagher Posted March 14, 2008 Share Posted March 14, 2008 Different foams have different fire spread ratings. The open cell foams are safe. Some of the closed cell are not. Fiberglass batts have a very high resistance, being that the batts are made of thin glass strands. Link to comment Share on other sites More sharing options...
Ross Posted March 15, 2008 Share Posted March 15, 2008 The Houston area home show guys on the weekend aren't fans of spray foam insulation. Unlike, say, This Old House, who seem to use it for everything. Link to comment Share on other sites More sharing options...

Ross Posted March 16, 2008 Share Posted March 16, 2008 I know Tom Tynan says foam insulaiton is overkill for here, and it makes it hard to ever do anything with the wiring or plumbing in those walls. We also don't need the moisture barrier the folks up North seem to require. I would be happy with fiberglass, myself. It doesn't smell at all, and is easier to control during installation (I made a box explode with the stuff during a training stint in a shipping departmetn years ago.)

Heights2Bastrop Posted March 17, 2008 Share Posted March 17, 2008 The Houston area home show guys on the weekend aren't fans of spray foam insulation. Unlike, say, This Old House, who seem to use it for everything.Most of the projects done on TOH are in the Northeast. Their insulation needs are much greater. What's better for them is not always best for this area. Link to comment Share on other sites More sharing options...

cnote Posted March 18, 2008 Share Posted March 18, 2008 I believe Tom Tynan spouts the health hazards of spray foam insulation, and the difficulty it can cause if there is ever a mold issue...I believe he said he would "not build a house in with foam insulation for a million dollars" to quote his radio show...

cgallagher Posted March 18, 2008 Share Posted March 18, 2008 Foam insulation is only useful if installed properly. All AC's must have fresh air intakes and they must be undersized so that they will run enough to cycle the humid air. The open cell foams are not vapor barriers. If you get a roof leak, the water will penetrate straight through. Don't install foam on a remodel. A foam insulated home has to be designed properly from the beginning. IE: no soffit or roof venting, outdoor air intakes, and downsized AC's. The cost savings over time can be very lucrative. Especially for larger homes. Do people really believe Tom Tynan answers to God? Link to comment Share on other sites More sharing options...
cnote Posted March 18, 2008 Share Posted March 18, 2008 I don't know much about Foam insulation, but Tom appears on a sponsored radio show purporting to be an expert on Home contstruction, repair, and maintenance. As such, I refer to him as a purported expert...just passing his opinion along to inform the OP of the information.Edit: We all answer to god...

As a side note, I used Tom to build my small house in the Heights two years ago. I am still very pleased with the project. Link to comment Share on other sites More sharing options...
