celotex Foil surface

Post by kamil Hamela » Thu Jan 04, 2024 4:09 am -1100

Hi,

im doings a flat roof assesment and the celotex product thjey are using has a aluminimum outer surface of sd-200. If the foil isnt taped together, do i include the foil in my analysis? If the foil is taped, do i then include this in the analysis?

thank you.

Hi,
a foil in the most cases has to be included in the analysis. You usually evaluate the critical section which includes the foil. You might take in account the the non taped foil by an reduces sd-value or by assuming an (higher) air flow through the construction.
