Sandwich Panel House Cost (EPS, PUF, Rockwool)
Estimate Korean-style sandwich panel house construction cost from floor area, panel type (EPS/PUF/Rockwool), and panel thickness. NPR/INR/PKR.
Stage breakdown
| stage | cost |
|---|---|
| Panel supply | NPR 3,32,500 |
| Installation labour | NPR 2,50,000 |
How this works
The total cost is split into two stages:
panelCost = area_ft2 × supplyRatePerFt2
installCost = area_ft2 × installRatePerFt2
total = panelCost + installCostThe default per-ft² panel-supply rate uses a base price plus a thickness multiplier:
EPS: 220 + 1.5 × thicknessMm
PUF: 280 + 2.0 × thicknessMm
Rockwool: 320 + 2.2 × thicknessMm
Glasswool: 250 + 1.8 × thicknessMmInstallation labour defaults to 250 per ft² regardless of panel type. Both rates are user-overridable so you can plug in a local supplier or contractor's quote.
Worked example
Floor area of 1,000 ft², EPS panel at 75 mm:
- Default supply rate =
220 + 1.5 × 75= NPR 332.50 / ft² - Panel cost =
1,000 × 332.50= NPR 3,32,500 - Install cost =
1,000 × 250= NPR 2,50,000 - Total = NPR 5,82,500
Foundation, steel frame, electrical, plumbing, and finishes are not included — see the related calculators for those line items.

FAQ
What does this calculator estimate?
It estimates the all-in cost of a Korean-style sandwich panel house: panel supply (the panels themselves at a per-ft² rate that varies with insulant type and thickness) plus on-site installation labour at a separate per-ft² rate. The headline figure is the sum of those two stages, scaled by your floor area.
How are EPS, PUF, Rockwool, and Glasswool priced differently?
The per-ft² panel-supply rate has a base price plus a thickness multiplier. EPS is the cheapest (≈ 220 + 1.5×thickness), Glasswool sits a step above (≈ 250 + 1.8×thickness), PUF is mid-premium (≈ 280 + 2.0×thickness), and Rockwool is the most expensive (≈ 320 + 2.2×thickness). PUF gives the best insulation per millimetre, while Rockwool is preferred for fire performance.
Which thickness should I pick — 50, 75, 100, or 150 mm?
50 mm is suitable for partition walls and warehouses with no insulation requirement. 75 mm is the common minimum for residential walls in temperate locations. 100 mm and 150 mm are used in cold-climate residential construction and cold-storage rooms. Thicker panels cost more per ft² but deliver a higher R-value and lower steady-state heat loss — see the Insulation Performance Calculator to compare options.
What's included in the installation labour rate?
The default 250 per-ft² installation rate covers panel handling, cutting, fixing to the steel frame, sealing of joints, and basic accessories. It does not include the structural steel frame, foundation, electrical, plumbing, or finishes. Site-specific factors — multi-storey work, remote sites, or short timelines — can push installation 30 to 50 percent higher; override the default with a local contractor's quote.
Are the foundation and steel frame included in this estimate?
No. This calculator covers the panel envelope only. Use the Prefab Foundation Calculator to size the PCC plinth or strip footing, and the Steel House Cost Calculator for the structural frame. Add those figures plus internal finishes (flooring, doors, paint, electrical, plumbing) to the panel cost to get a total turn-key budget.
Does changing the currency convert the cost between markets?
No. The currency selector is a labelling change only. The default rates were calibrated for the Nepal market and the numeric figures stay exactly the same when you switch to INR or PKR. To estimate a panel house in India or Pakistan, override the supply and installation rates with locally quoted figures and select the matching currency code.
