My radiant experience with Warmboard - GreenBuildingTalk - GreenBuildingTalk - Green Building Forums on Insulating Concrete Forms (ICF), Structural Insulated Panels (SIP), Radiant Heating, Geothermal Heat Pumps, Solar Power, Green Construction Projects -
First, let me say that I do not, nor do any relatives, work for Warmboard or have any other kind of relationship to the company.
I'm just a home owner that used this forum over three years ago to find out about radiant heating and wanted to contribute back by writing about my experience with installing Warmboard. We live in eastern Iowa (near Cedar Rapids). We lived in a house with 1,300 sq. ft. on the first floor and an additional 750 sq. feet of finished living space in the basement. We had a forced air gas heating system as well as a Mendota fireplace in the basement. With a special needs child in mind, we were looking to build a house with a better layout and some different features that would better fit our situation (zero-entry, open floor plan, enclosed stairwell....). After about five revisions on a floor plan we started plotting out the build of a 1,950 sq. ft. house (1,750 in the walk-out basement). We moved in on Dec. 4, 2006 and instantly fell in love with radiant heating.
Radiant Floor Heating: gypcrete or other light weight concretes, wood subfloors, radiant floor heating. Expert: Morgan M.
Audetat - 8/22/2007 QuestionWhat is the thermal value difference between gypcrete and other light weight concretes. We are putting 1.5" concrete floors with radiant floor heating over wood subfloors in our new construction home. I've heard that gypcrete and other light weight concretes aren't as efficient as a thermal mass as regular concrete mixtures are. AnswerGypcrete vs. concrete, The debate goes on. The lightest concrete I believe is aerated making it light but also more resistant to heat transfer. Even distribution and silent operation are my favorite attributes and both Gypcrete and concrete provide fire and sound barriers. Remember your crack isolation barrier if you plan to tile over any suspended floor. Good luck, PS. R Values for Concrete** Based on data from 1993 ASHRAE Handbook, Table 4 Typical Thermal Properties of Common Building and Insulating Materials-Design Values These are relatively low R values as heavy carpet can easily add an R3 to your project.
