Q: WHAT LAMINATION WAYS DO YOU USE?
A: We have plastic extrusion, glue laminations with our accurate machines & professional technics to control the good quality.
The lamination way is according to customer's requirement or our rich experience.
Q: CAN I ORDER PERFORATED & PRINTED PRODUCTS?
A: Yes, PERFECT can perforate its full line of insulation facings & arrange printing for foils.
Perforations are available in the following options:
Full coverage where 100% of the exposed surface is pin perforated. This is designed for application where the facing is typically not laminated to the fiberglass.
Pattern or "Channel" perforated to allow for easy laminating. This technique allows the facing to be laminated to fiberglass with no adhesive bleed through.
Q: WHAT IS THE MAXIMUM INDOOR HUMIDITY THAT AVOIDS MOISTURE PROBLEMS?
A: The maximum recommended continuous indoor relative humidity (RH) varies from 30% to 45%, depending on geographic location. General guidelines by region of the country can be found here. An engineer should be consulted to determine the correct HVAC design for a specific facility.
Q: WHAT HAPPENS WHEN A FACING BECOMES WET AFTER INSTALLATION?
A: Typically, insulation facing will not be affected by limited exposure to water if allowed to fully dry. Prolonged exposure to water can potentially result in a loss of certain physical properties.
Q: WHY DO YOU OCCASIONALLY EXPERIENCE STAINING OF FOIL FACED INSULATION?
A: Improperly ventilated bags are the primary cause of staining.
Black or brown staining is caused by extended exposure to moisture on the surface of the foil.
Potential sources of moisture are: Adhesive used to laminate the facing to fiberglass, Improper job site storage, Exposure to curing concrete, Daytime/nighttime temperature changes
