Schluter DITRA-HEAT-DUO-PS Peal & Stick Uncoupling Membrane

Schluter DITRA-HEAT DUO Peel & Stick Membrane Roll

Schluter-DITRA-HEAT-DUO-PS is a peel and stick membrane that features a pressure-sensitive adhesive (PSA) to bond the membrane to the substrate, eliminating the need for thin-set mortar.

Features

• Pressure-sensitive adhesive (PSA) which bonds the membrane to the substrate, eliminating the need for thin-set mortar
• Quick and easy to install, DITRA-HEAT-DUO-PS is an uncoupling membrane with an integrated bonding fleece that provides sound control, as well as a thermal break
• Provides electric floor warming for use beneath tile, stone, or other resilient floor coverings (e.g. LVT)
• Reduces impact sound transmission through floor-ceiling assemblies, making it ideal for multi-story construction
• Reduces heat loss to the substrate for up to 70% faster heat-up times over concrete during temperature increase demands
• Nominal 5/16" (8mm) thickness minimizes tile assembly thickness and reduces transitions to lower surface coverings
• Self-leveling compounds are not required to encapsulate the cables into the membranes
• Stud structure of DITRA-HEAT-DUO is specifically designed to allow for the easy installation of DITRA-HEAT-E-HK heating cables
• Comes in two sizes: 8.4 sq ft (0.78 m2) sheet and 108 sq ft (10 m2) roll
• 8.4 sq ft sheet dimensions: 3' 2-5/8" x 2' 7-3/8" (0.98 m x 0.80 m = 0.78 m2)
• 108 sq ft roll dimensions: 3' 2-5/8" x 33' 6-1/2" (0.98 m x 10.20 m = 10 m2)

How To Use

• Simply remove the transparent release film from the fleece side of the membrane to expose the layer of adhesive, and embed into substrate
• Apply peel and stick membrane to the floor, fleece/adhesive side down. Solidly embed the matting into the substrate using a float, screed trowel, or DITRA-ROLLER
• Abut adjacent sheets and align the studs on the top of the matting to make subsequent heating cable installation easier
• No thin-set required to install membrane means a faster and easier installation
• The membrane can easily be repositioned until pressure is exerted
• Self-leveling compounds are not required to encapsulate the cables into the membranes
• If application area requires a membrane that meets or exceeds requirements of ANSI A118.10, please refer to thin-set versions of DITRA-HEAT and DITRA-HEAT-DUO
• Alternatively, the DITRA-HEAT-PS or DITRA-HEAT-DUO-PS membranes may be covered with the Schluter-KERDI membrane, which is certified to meet ANSI A118.10

What is the spacing requirements for DITRA-heat?

A cable spacing of 3 studs between runs is standard. However, cable may also be spaced at continuously alternating 3 stud – 2 stud intervals in isolated areas or over the entire floor.

Does DITRA prevent tile from cracking?

The rib structure allows for in-plane movement that effectively neutralizes the differential movement stresses between the substrate and the tile, thus eliminating the major cause of cracking and delaminating of the tiled surface.
