Prodeso Preformed Inside Corner 6″ x 6″ for Membrane (Each)

Waterproofing for the room is in the layer above the floor heating system. The layers for waterproofing this type of floor are:

• subfloor
• thinset
• uncoupling membrane
• tempzone heating cable
• waterproofing tape for seams and corners
• thinset or self leveling cement
• tile floor

Insulating underlayments and uncoupling membranes share some key characteristics like providing crack isolation benefits, but they are separated by their primary functions.

Insulating underlayments, like WarmlyYours ThermalSheet, provide a thermal break between a subfloor and the heating elements, which can help prevent the concrete from acting as a “heat sink” and increase energy efficiency. ThermalSheet has a 1.5 R-value, and it offers crack isolation of up to ¼”. This can be particularly beneficial if you are trying to heat a room above a cement slab or above an unheated garage. 

Uncoupling membranes, like the Prodeso membrane, are great for protecting relatively fragile floor coverings like tile from foundational movement. They also allow for faster installation times than many other types of floor heating.

The height of the membrane itself is just about 1/4" (7/32").

This membrane provides many benefits including speedy installation, uncoupling, crack isolation, vapor management, and load distribution.
