6 PROGRESS PROFILES - PRODESO HEAT SYSTEM
Wood
Wood and its derivatives are commonly used in today’s construction. All wood materials
expand, contract, bend, and flex with changes in temperature, humidity, and load in the
surrounding environment. These deformations can be seasonal or due to an isolated
incident such as a plumbing accident, and will naturally occur over the life of a building
structure.
PRODESO HEAT SYSTEM properties provide a solution for these challenges.
PRODESO HEAT MEMBRANE will compensate for relative longitudinal movement between the
Sub-floor and the tiles eliminating the major cause of tile cracking and delamination making it possible
to install underfloor electric heating on wood substrates. PRODESO HEAT MEMBRANE eliminates the
need for the second layer of Plywood with the exception of Natural Stone tile installations.
Wood is particular sensitive to relative moisture changes in their environment. PRODESO HEAT
MEMBRANE unique and patented design allows for air pockets to form between the subfloor and the
membrane itself. These air pockets allow for a vapor cycle to form and balance the vapor content of the
subfloor assembly, increasing the mechanical and structural property of the wood subfloor.
Wood structures are particularly sensitive to variation in humidity in their environment. PRODESO HEAT
MEMBRANE is made of polypropylene, a completely waterproof substance, that will protect the wood
subfloor from water damages to ensure a long lasting installation. For areas prone to flood please follow
the waterproofing instructions on page 17.
PRODESO HEAT MEMBRANE unique and patented designs allows loads to be evenly distributed from
the tile covering to the subfloor. Each rounded square relief has a central cavity shaped like an inverted
pyramid. When filled with thin-set this inverted pyramid becomes an incompressible structure. These
cavities act like pillars in a building support structure, evenly distributing and transferring the load from the
tile floor to the subfloor below.
PRODESO HEAT MEMBRANE
The uncoupling membrane is laid directly over the entire surface
intended for tile installation. The heating cable is then installed
in the areas where heat is desired using the channels formed
between the rounded square reliefs. It’s NOT necessary to use
self-leveling cement to cover and protect the wire before starting
tile installation. This results in significant savings of material, time,
cost and overall weight. Tile installation can start immediately after
installing the heated cable.
