Primary Framing Systems

Building width: No matter what primary framing system is used, the building width is defined as the distance from outside fo eave strut of one sidewall to outside of eave strut of the opposite sidewall.Building width does not include the width of Lean - to buildingS or roof extentions

W-EPS950/1000/1150

EPS Wall Panel

EPS wall panels combine expanded polystyrene core with Aluzinc galvanized steel facings, delivering cost-effective thermal insulation with R-values from 1.2 to 3.6 m²K/W for industrial and commercial buildings.

W-EPS960/950

EPS Roof Panel

EPS roof panels feature higher-density EPS core (12–22 kg/m³) with Aluzinc steel facings, delivering lightweight, insulated roofing with overlapping joint design for superior weather protection and thermal efficiency.

W-RW950/1000

Rockwool Wall Panel

Rockwool wall panels combine non-combustible mineral wool core (80–120 kg/m³) with Aluzinc steel facings, achieving A2 fire rating and R-values up to 5.6 m²K/W for fire-safe building envelopes.

R-RW950/1000

Rockwool Roof Panel

Rockwool roof panels offer fire-rated, acoustically insulating roofing with mineral wool core and PU edge sealing, delivering R-values up to 5.6 m²K/W and A2 fire safety for industrial facilities.

W-PU1000

PU Wall Panel

PU wall panels feature polyurethane core (40 kg/m³) with Aluzinc steel facings, delivering superior thermal insulation with R-values from 1.4 to 9.1 m²K/W in thinner profiles than conventional panels.

R-PU1000

PU Roof Panel

PU roof panels deliver premium thermal performance with polyurethane core and Aluzinc steel facings, offering R-values up to 9.1 m²K/W and double tongue-and-groove joints for superior airtightness.

FAQ Related To Building Materials

What types of insulated sandwich panels do you provide?

We offer EPS, Rockwool, and PU sandwich panels for both walls and roofs, with thicknesses ranging from 50mm to 200mm to meet different thermal and fire-rated requirements.

How do your building materials perform in extreme weather?

Our panels use AZ40 Aluzinc galvanized steel facings with 20um PE painting, providing excellent corrosion resistance. The Zlock tongue-and-groove and hidden screw connections ensure superior waterproofing and wind resistance.

Can I customize the color and appearance of the wall/roof panels?

Yes. We offer RAL color customization, 3D rendering for pre-visualization, and various surface finishes (like corrugated or flat) to match your specific architectural aesthetic.

What is the maximum length of your sandwich panels for large-scale projects?

Our panels can be manufactured up to a maximum length of 11.8 meters, significantly reducing on-site joints, speeding up installation, and improving overall building sealing.

Do you provide glass curtain walls as part of your building materials?

Yes. We offer fully transparent Glass Curtain Walls, including Aluminum Frame, Invisible Frame, and Point Supported systems, adding modern aesthetics and natural light to commercial buildings.
