Pertanyaan dan jawaban umum seputar alat ini.

Yes β€” many assemblies layer materials, such as fiberglass batts plus rigid XPS foam sheathing, and their R-values simply add together.
No β€” this tool sums only the entered material layers; use the Thermal Resistance Calculator to add interior/exterior air films for a full assembly U-value.
