nVent NUHEAT Peel & Stick Membrane is now available through authorized nVent NUHEAT distributors! This innovative new product enables the installation of uncoupling membrane onto a substrate without the use of thinset.

How nVent NUHEAT Peel & Stick Membrane Works

nVent NUHEAT Peel & Stick Membrane does not have a layer of fabric bonded to the bottom like our standard Membrane; instead, a pressure sensitive adhesive is applied directly to the underside of the polypropylene structure and the adhesive is protected by a release liner.

The other unique features of nVent NUHEAT Peel & Stick Membrane are the mortar vents cut into the top of each pillar. These vents ensure a permanent bond by allowing mortar applied above the membrane to adhere to both the substrate and the floor covering materials.

The first step when installing any membrane product is to dry fit the membrane for the entire area, ensuring you have sufficient supply for the job and cutting down sections to facilitate fitment as required.
Once the pre-fitting is complete, the substrate must be cleaned and then prepped with any standard acrylic floor primer, readily available at most home improvement retailers and flooring distributors. Once the primer has begun to dry and feels slightly tacky to the touch, the release liner can be removed and Peel & Stick Membrane can be applied to the treated surface.

The bond created between the adhesive and the treated substrate is very strong; however, to ensure a long-lasting, high-performance floor assembly that lives up to the nVent NUHEAT 25-year product warranty, the final permanent bond relies on the mortar applied on top of the membrane. Mortar flows through the vents, bonding to the substrate below. By applying either modified or unmodified thinset mortar to embed the heating cable and secure the floor covering, air gaps within the membrane pillars are sufficient to ensure the assembly still achieves the same ‘High Performance’ rating on the ANSI A118.12 System Crack Resistance test that the standard nVent NUHEAT Membrane achieves.

Detailed installation instructions can be found in the nVent NUHEAT Membrane Datasheet.

It is important to note that nVent NUHEAT Peel & Stick Membrane cannot be used for waterproofing due to the mortar vents. Also, it is only available in 39” x 39” sheets (25 per box).

If waterproofing is required, the installer prefers rolls of Membrane rather than sheets, or if an installation requires an ‘Extra Heavy’ rating on the Robinson Floor Test (ASTM C627), our standard nVent NUHEAT Membrane is fulfills those needs.

Benefits of nVent NUHEAT Peel & Stick Membrane

This innovative new solution has many benefits when compared to membranes requiring thinset underneath…

Less time: takes 40% less time to install based on contractor time trials

Less mess: Eliminating the lower layer of thinset means it doesn’t ooze up through the seams and no mixing or cleanup of thinset is required when installing the membrane onto the substrate

Less cost: the required acrylic flooring primer is a fraction of the cost of thinset

Electrician friendly: for electrical installers or other trades averse to mixing thinset, this system is much easier to use and it provides protection for the heating cable while waiting on the flooring contractor to show up on site

An ideal surface for tile setters: non-flooring trades can install this system, confident that a tile setter will approve of its uncoupling and weight-bearing properties

Less floor height build-up: Eliminating the lower layer of thinset reduces the total height of the floor assembly by about 1/8”, lessening the likelihood that transition strips are required for adjacent flooring surfaces

No modifications required for cable fitment: accommodates nVent NUHEAT Cable, including the cold lead joint, the end seal, and the sensor probe without cutting or modification

No concrete anchors required: unlike certain cable guide installations, this system installs over concrete without the mess and work associated with concrete anchors

High performance crack resistance: achieves the same ‘High Performance’ rating on ANSI A118.12 System Crack Resistance test as regular nVent NUHEAT Membrane

Exceeds residential rating on the Robinson Floor Test: achieves a ‘Moderate’ rating on ASTM C627

25-Year Product Warranty: all nVent NUHEAT in-floor systems are covered by we our 25-Year Product Warranty

25-Year Total Care Warranty: all nVent NUHEAT in-floor systems are eligible for the 25-Year Total Care Warranty when installed by an nVent NUHEAT Certified PRO
