Problem: Moisture and Mold Growth
Moisture damage and mold or bacterial growth has become a widespread problem for many building
owners. The topic has received attention from both industry groups and the media, yet many hotels, hospitals, office buildings
and homes still become damaged or unusable because of poor moisture management that results in the growth of mold and mildew.
Four components generate the growth of mildew:
1. mold spores that permeate the air in warm, humid climates;
2. nutrients(food supply) found in construction materials;
3. temperature;
4. moisture.
When impermeable wallcoverings like vinyl are used, water vapor becomes trapped behind the
wallcoverings. More important, the impermeability of the wallcovering prevents the wall cavity from drying out. Since water
vapor is driven into the insulating cavity by the high outdoor humidity, it becomes trapped and the condensed water can't
evaporate. The insulating cavity then stays wet for months. During this time mold can easily grow and structural members can
buckle or corrode. |

Solution:
Product Description
ISC Glass Textile Wallcovering Collection of woven glass textile fabrics is specifically designed
to allow moisture diffusion and is breathable to reduce the risk of mold and mildew. The range of patterns in the JM Collection
offers the functionality of paintable glass textiles and the versatility of color and design flexibility. |
| |
Applications
The JM Collection is suitable for interior wall and ceiling applications and can be installed
over most surfaces with minimal preparation. It is ideal for offices, hotels, restaurants, healthcare facilities, and other
commercial as well as residential installations in high humidity geographic areas. |
| |
Advantages
The paintability of the wallcovering expands design options with patterns ranging from subtle
to dramatic while providing the strength, durability, health, and safety of woven glass textiles. Glass textile wallcoverings
are made from readily available natural materials with no toxic components, are flame retardant, and breathe to vent moisture
minimizing the potential for mold and mildew growth. Glass textiles are dimensionally stable and provide a durable system
that strengthens walls. |

Installation Instructions
Follow ISC installation instructions for high humidity areas utilizing suggested wall surface
primers and paint coatings. Follow standard ISC installation instructions for the fabric making sure not to leave any space
when butting seams. Otherwise, the space may be visible after painting. Match the pattern as appropriate. Wipe any excess
adhesive from the front side with a moist sponge. After 24 hours or when completely dry, roll a high quality latex paint (preferably
with anti-microbial additives) in the desired color over the fabric working the paint into the weave. |

Recommended Paint
Use two coars of high quality satin sheen or less paint, preferably with anti-microbial additives.
