Lissafta adadin allunan EPS/XPS, girma da juriya ta zafi (R) bisa yanki, kauri da girman allon da aka zaɓa.
| Metric | Dabara |
|---|---|
| Ƙarar Murya | Faɗi × Kauri (+ kaso na ajiya) |
| Adadin alluna | (Area + margin %) ÷ board area, rounded up |
| Jurewar zafi (R) | Kauri (m) ÷ λ (W/mK) |
Yawan R-value, mafi kyawun rufin zafi. Ka'idodin gini (misali ga gidaje na aji A++) yawanci suna buƙatar R ≥ 5–7 m²K/W ga bango ko rufi — duba buƙatun takamaiman aikinku.
EPS (kumfa polystyrene mai faɗaɗawa) ya fi arha, ana amfani da shi don bango da tushe marasa nauyi. XPS (polystyrene da aka fitar) ya fi yawa, ya fi jure danshi da matsi, ana amfani da shi don tushe, filaye da rufi a ƙarƙashin nauyi mai yawa.
Ƙarin graphite yana rage ikon watsa zafi (λ) da kusan 15–20%, don haka za ka sami R-value ɗaya da ƙaramin Layer — yana da amfani idan sarari ya yi ƙanƙanta.
