Perforating LANARK Wallcovering

A superior process results in greater permeability without compromising appearance

As a result of its construction, vinyl wallcovering – including LANARK Wallcovering – has little or no permeability, because it allows little or no transfer of water between its surfaces.  The permeability of vinyl wallcovering can be increased, however, through perforation – the process of creating tiny holes in the surface of the wallcovering to allow the passage of water vapor.  For those building installations that require it, LANARK Wallcoverings can be perforated.

As you might expect, different perforation processes will yield different results – both in the resulting appearance and permeability of the wallcovering.  You'll be pleased to know that the perforation technique that can be applied to LANARK Wallcoverings on a custom basis at our manufacturing facility greatly increases its permeability without compromising its appearance.

During this OEM perforation process, 200 "micro" holes per square inch are placed in the surface of LANARK Wallcoverings – most other perforated wallcoverings may have only 150 to 180 holes per square inch.  Unlike mechanical punching system, our process uses heated pins that melt through the wallcovering to create clean, consistent and evenly-spaced holes – holes that aren't obstructed by leftover vinyl waste.

Nor do the holes affect the overall appearance of the wallcovering.  They are nearly invisible to the naked eye once the wallcovering is installed, yet provide a porous surface with permeability ratings similar to some paints and greater than conventional vinyl wallcovering.

The strategy of using perforated vinyl wallcovering in certain building installations is to minimize the incidence of mold on the wall surface behind the wallcovering.  Perforating the wallcovering allows it to "breathe," so that water vapor can pass through its surface and is not trapped behind the surface where it can contribute to mold growth.

CAUTIONS:
Wallcovering – including perforated wallcovering – is not a solution for and should not be used in any buildings which have or may have wall or wall cavity moisture accumulation or other moisture problems. Wallcovering – including perforated wallcovering – will not prevent mold growth or other moisture related damage if moisture accumulation is permitted to occur in a wall or wall cavity.

Due to its higher permeability, perforated wallcovering will not prevent building interior liquid or vapor moisture from going through the wallcovering into the wall or wall cavity.  Protecting walls from interior liquid or vapor moisture intrusion can be an important requirement in many applications.
