Abstract
A membrane for decoupling heated flooring from a subfloor includes a flexible base and a plurality of projections formed into the base and extending outward from the base. Each projection of the plurality of projections has a perimeter wall defining a height of the projection and a top surface integral with the perimeter wall for supporting a flooring adhesive and/or for bearing a load when the heated flooring is installed. The projections have one flange portion extending from the perimeter wall and effective for retaining a heater cable within a channel formed between each pair of adjacent projections. Each channel may have exactly one flange portion extending over it and forming an overhang for retaining heater cables of different diameters. The corresponding flange portions of adjacent projections do not face in the same direction or the opposite direction, providing for a minimum number of flange portions to be used.
