Where is Gyproc Foilbacked Board typically used?
Used primarily in:Internal concealed ceilings such as attics and garret rooms where heat protection is essentialPartition walls, linings, and suspended ceiling systems in industrial and commercial buildingsSpaces exposed to extreme temperatures needing heat gain or loss management
What are the key benefits of Gyproc Foilbacked Board?
Provides improved thermal insulation by reflecting heat radiationActs as a moisture and vapor barrier to reduce condensation risksEnhances durability in environments subject to temperature fluctuationsIdeal for use in insulated wall systems and ceiling assembliesHelps maintain comfortable indoor temperatures and reduce energy costs
How does the aluminum foil backing contribute to thermal performance?
The aluminum foil reflects approximately 95% of radiant heat, reducing heat transfer through the board and thereby improving the overall thermal insulation of the building element.
Can Gyproc Foilbacked Board help prevent condensation?
Yes, by acting as a vapor barrier, the foil backing limits moisture ingress and helps prevent condensation within wall and ceiling cavities.
Is Gyproc Foilbacked Board suitable for exterior use?
No, this board is designed mainly for interior applications in concealed ceilings, partitions, and linings. For exterior or wet area use, specialized exterior-grade or moisture-resistant products should be considered.
How should Gyproc Foilbacked Board be installed?
Installation is similar to standard gypsum boards but care should be taken to maintain the integrity of the foil backing to ensure vapor barrier performance. Joints should be properly sealed, and recommended fasteners and installation methods followed as per manufacturer guidelines.
Can Gyproc Foilbacked Board be finished with standard interior finishes?
Yes, the front grey face paper can be finished with paint or other decorative treatments after jointing and taping.
How does this board improve energy efficiency in buildings?
By reflecting radiant heat and acting as a vapor barrier, Gyproc Foilbacked Board helps reduce cooling and heating loads, contributing to energy savings and enhanced occupant comfort.
