Define the Interior Conditions
Start with whether the building is conditioned, how it is used and what products or processes it contains. Offices, workshops and storage areas can have different needs within the same facility.
Discuss occupancy, operating hours and moisture-producing activities with the design team. Those inputs help establish the enclosure and building-system requirements.
Coordinate the Whole Assembly
Insulation is one part of the roof and wall assembly. Air control, moisture management, penetrations, doors and other transitions require compatible details.
Review the building supplier’s systems and installation requirements with the project designers. Product selection should follow the project design rather than a single advertised insulation value.
Price a Defined Enclosure Scope
Ask proposals to identify the roof and wall assemblies, insulation system, openings and relevant details. Clarify who provides and installs each component.
For an existing building, share photographs and available drawings. Alterations may require investigation of the existing assembly before an appropriate scope can be established.
