Deewar ka R-value kaise nikaalein?

Har layer ka R-value joden aur air film joden. Har layer ka R = motai (inch) × material ka R per inch.

R-value aur U-factor me kya farak hai?

Ye ek doosre ke ulte hain. R garmi ke bahav ka pratirodh naapta hai — zyada behtar; U bahav naapta hai — kam behtar.

RSI ko R-value me kaise badlein?

RSI ko 5,678 se guna karein. RSI 3,5 lagbhag R-19,9 hota hai, isiliye code me dono barabar dikhte hain.

Framing R-value kyun ghatati hai?

Lakdi insulation se kaafi behtar garmi le jaati hai, isliye stud cavity ke aas-paas thermal bridge ban jaate hain.

Insulation R-Value Calculator ke baare mein

Deewar ki layers series me hoti hain, isliye unke thermal resistance seedhe jud jaate hain: drywall, insulation, sheathing, siding aur dono taraf hawa ki patli film. U-factor us kul ka ulta hai, aur heat loss hai U × area × temperature difference. Catalogue jo chhod dete hain wo hai framing: stud aur plates insulation ko bypass karte hain, aur dono raaston ka ausat lein to nominal R-13 deewar asal me R-11 jaisa kaam karti hai. Yahan pura assembly layer-dar-layer banta hai aur ek season ki heat loss ka daam bhi lagta hai.

Features

Assembly layer-dar-layer, R per inch ke saath
Insulation, sheathing, structure aur finish materials
Andar aur bahar ki air film, optional
RSI aur W/(m²·K) ke saath imperial R aur U
Framing ke saath whole-wall R-value
Ghante ki heat loss BTU me aur season ki fuel laagat

Insulation R-Value Calculator kaise use karein

Har layer andar se bahar ki taraf, motai ke saath joden
Kul R-value, RSI aur U-factor padhein
Assembly type aur climate chunkar target se milaayein
Area, temperature difference aur fuel daam se laagat nikaalein

Example

Input

½″ drywall + 3½″ fibreglass batt + ½″ OSB + 1″ EPS

Output

R-17.10 · RSI 3.01 · U-0.0585
Whole-wall with 23% framing: R-13.9

Foam board ka ek continuous inch dikhne se zyada kaam karta hai — sirf yahi layer studs bypass nahi karte.

Common errors aur troubleshooting

Kul value deewar ke asli pradarshan se zyada hai. — Aap cavity ke beech ka value dekh rahe hain. Framing pratishat set karein — 23 % aam hai — aur whole-wall value lein.
European datasheet ke R value bahut chhote lagte hain. — Wo RSI hain, metric roop. Ek RSI = 5,678 imperial R, to RSI 3,5 matlab R-19,9.
