Radiant Heat And Ceramic Floor Tile
If you have radiant heat and are planning a ceramic floor tile installation, then understanding the function of
membranes will certain be beneficial says Heating and Air Knoxville TN. This article will teach you about
various membranes in conjunction with radiant heat, so that your floor tile installation will be done properly.
There have been many tragic ceramic floor tile installation disasters by using the wrong membranes or none
at all. If the membranes and/or bonding mortars are not compatible your bond will be lost and problems will
With a floor tile installation make sure your membranes meet current ANSI standards and that
manufacturers instructions are followed properly.
With floor tile installations, membranes are used for a variety of reasons, each having a specific purpose,
such as moisture vapor emission membranes, cork underlay, peel and stick membranes and liquid or trowel
A load bearing, bonded, uncoupling membrane is also a full coverage membrane, but it’s made of thicker
material than the anti-fracture membrane. The air cavities that are pressed into its surface allow for lateral
A cleavage membrane is not bonded to the concrete. The function of this membrane is to separate the tile
assembly from the concrete and isolate the wire-reinforced mortar bed and the ceramic floor tile installation
from any instability in the wood or concrete sub-floor.
A crack isolation membrane is bonded to the sub-floor to cover existing shrinkage cracks and must cover
three times the width of the floor tile used, with a minimum width of 6 inches.
An anti-fracture membrane is also bonded to the sub-floor, but this membrane needs to fully cover the sub-
floor in order to protect against shrinkage, moisture and expansion and/or contraction of the concrete.
With a radiant heat system a moisture barrier is important in controling moisture and stoping liquid from
passing through. Heating and Air Knoxville TN would like you to always consider all of the options,
because the improper use of a membrane may trap moisture and cuase condensation.
Just remember that when you’re doing a ceramic floor tile installation make sure that you use the correct
membrane especially if you have in-floor radiant heating otherwise you could end up with cracked tile and
grout and an expensive repair bill.
