PEB Wall Selection – Which Wall for Which Building?

Building Requirement Suitable Wall Options
Lowest-cost industrial shed Profile Sheet
General warehouse Profile Sheet / EPS / PUF
Temperature-controlled building PUF
Cold storage PUF / specialized insulated panels
High fire requirement Rockwool / tested fire-rated systems
Acoustic requirement Rockwool / appropriate acoustic assemblies
Permanent office AAC / Fiber Cement / Glass / ACP
Premium facade Glass / ACP
Heavy-duty industrial area Precast / masonry / engineered panel
Corrosive environment FRP/GFRP / suitable coated systems
Natural daylight Translucent FRP / polycarbonate systems
Modular building PUF / EPS / Fiber Cement
Residential prefab PUF / Fiber Cement / AAC

Most Important Factors Before Selecting a Wall

A professional PEB wall specification should consider:

Thermal Insulation

How much heat transfer is acceptable?

Fire Safety

What fire resistance/classification is required for the building?

Acoustic Requirement

Is the building near machinery, traffic or residential areas?

Wind Load

The cladding and fixing system must be designed for applicable wind pressures.

Corrosion Environment

Coastal, chemical and high-humidity environments may require special coatings/materials.

Building Height & Panel Span

The wall system and support spacing must be structurally adequate.

Appearance

Colour, profile, façade design, glazing and architectural finishes.

Maintenance

Consider cleaning, repainting, replacement and access.

Budget

Initial cost should be compared with lifecycle and energy costs.

Installation Speed

One of the major advantages of prefab construction is rapid installation.

Profile Sheet Wall – Single Skin

Construction: Colour-coated/GI profile sheet fixed to steel girts or Z/C purlins.
