EPS & rockwool panels (comparison)

Two other common sandwich-panel cores. EPS is cheaper and less insulating. Rockwool is non-combustible and heavier. This page compares them with PUF/PIR so you can choose the right core; ask us if your project needs one.

Why this panel

What you get

1

PUF/PIR insulates best

k ≈ 0.022 against ≈0.035–0.038 (EPS) and ≈0.040–0.045 (rockwool) W/mK. For the same U, PUF can be much thinner.

2

Rockwool for fire walls

When a tested fire-resistance rating is needed, rockwool is the usual choice.

3

EPS on budget

Fine for dry, ambient-temperature cabins. Not recommended for cold rooms.

Tongue & grooveScrew-fixed or hidden-fix
Continuous family: made on a continuous line, tongue-and-groove edge, cut to length. Typical; varies by brand. Continuous or cam-lock?

Thermal performance

U-value by thickness

Calculated for the core with k ≈ 0.022 W/mK (PUF reference; EPS and rockwool need 1.6–2× the thickness for the same U). Lower U means less heat gets through. U = 1 / (0.13 + d/k + 0.04).

The core only. Joints, fixings and doors add heat gain in a real room. Which thickness for which temperature?

Questions

EPS / rockwool vs PUF panel FAQ

Typical values; the quote and the maker’s datasheet state the figures for your order.

What thickness does the eps & rockwool panels come in?

Commonly 50, 75, 100, 150 mm (typical; varies by brand). Continuous panels are cut to length on the line.

What is the U-value of a 100 mm eps & rockwool panels?

About 0.21 W/m²K, calculated for the core with k ≈ 0.022 W/m·K: U = 1 / (0.13 + d/k + 0.04). Joints, fixings and doors add heat gain in a real building.

What is the core density and skin?

Core density EPS 15–20 kg/m³ · Rockwool 80–120 kg/m³ (typical). Skins: Coated steel 0.4–0.6 mm. Cover width ~950–1200 mm.

Is the eps & rockwool panels fire rated?

Rockwool: non-combustible core; tested wall systems carry fire-resistance ratings. EPS: combustible.

What is the price of the eps & rockwool panels?

The panel rate depends on thickness, skin gauge and coating, core, brand and quantity, so we quote today’s rate per brand for your specification. Transport is extra and quoted separately for your pincode; flashing is made as per your requirement.

Where is the eps & rockwool panels used?

Rockwool: fire walls, compartment partitions; EPS: budget cabins, temporary sheds.
