2. More Recent Tile Application Method:

Underlayment Use:

a. Water shedding component

b. Load path structural component

Product Approval Limits of Use:

a. Traditional underlayment code standards

b. Rated uplift resistance as a structural component in the load path

Code Test standards for this type of product include FM4470 D, TAS 114 D

Permitting:

Permit Applicant is required to demonstrate that the proposed construction meets the design loads for the specific projects.

Note: Existing assembly/partial assembly product approvals can be combined to demonsrate code compliance. If multiple approvals are used in combination, usually the weakest link in the load path is the resistance capacity of the whole assembly.

Building Official (AHJ) verifies that the submittal meets code requirements.
