Radiant Heat Gypcrete Floors

During the installation process one of the most important steps to take is to turn on the radiant heat system 1 2 weeks prior to the delivery of the wood.

Radiant heat gypcrete floors. R value is an important consideration when looking for underlayment and becomes even more important when looking for a radiant heat compatible underlayment. Cerazorb is also the recommended underlayment for heating on top of a concrete slab and is often paired with our tempzone floor heating products. R value is how well a two dimensional barrier like underlayment resists the conductive flow of heat. Gypcrete with a 1 4 to 1 2 thickness is then pumped directly over pex tubing.

Both insulating underlayments will also provide some degree of crack isolation benefits. Radiant heat is considered a dry heat and if the heating season lasts for several months a humidification system should be installed to keep the relative humidity above 30. Gypcrete can also help simplify the radiant heat wood floors installation process. Therma floor encases the tubes or cables in crack resistant noncombustible gypsum.

Posted april 27 2017. Gypcrete is a lightweight concrete product that is applied over pex tubing. With gypcrete pex tubing is stapled directly to subflooring. Best flooring properties for radiant heating.

You need an underlayment with high enough r value to make sure that your radiant heating system is not losing heat given off to the sub. It acts as the thermal mass for any radiant floor system. Gypcrete for radiant heat wood floors. It encases the hot water tubes or electrical cables without air bubbles creating a superior thermal mass that provides uniform heat transfer.

Its special formula resists breakdown to 150ºf 66ºc. Gyp span radiant is a gypsum concrete floor underlayment designed specifically for use over radiant heating systems. The gypsum underlayment is designed to pour over tubing encasing the tubes in crack resistant noncombustible gypsum acting as the thermal mass. Cerazorb is a synthetic underlayment that has a higher degree of thermal resistance r value of 1 5 than cork.

Properties that make a floor covering good or bad for radiant heating systems tend to center around the thickness of the flooring the flooring s thermal conductive nature its tendency to expand and contract and whether it is prone to water and heat damage. Therma floor gypcrete installation method.
