Placement changes performance
The product needs the documented orientation and adjacent air space. Roof deck or rafter conditions,
attic access, dust, moisture, ventilation, existing insulation, ducts, wiring, and other equipment can affect
feasibility and installation. Product instructions govern the final assembly.
What to share
Provide property type and use, attic or roof configuration, current insulation, ventilation, access, moisture history, HVAC or duct location, any selected product, and safe photos. State the comfort problem or project goal rather than assuming one material is the answer.
Does radiant barrier replace insulation?
No. It serves a different function. The existing insulation, air leakage, ventilation, roof assembly, HVAC,
and building use still need review.
Describe the attic or roof assembly, current insulation, access, and project goal.
