Roofing Challenges & Our Solution

Challenges

Thin / recycled-core panels: low insulation, uneven hardness, collapse, short life, easy leak.
Rockwool panels: excellent fire but high cost and heavier handling.
Moisture: poor cores absorb water, grow mold, rust the roof.
Harsh outdoor: cheap paint fails salt-spray / UV tests, ages fast.

Our Solution

Guaranteed 100mm full core: stable insulation, long-term energy saving.
Virgin EPS beads: uniform hardness, no collapse, longer service life.
Lapped waterproof joint + sealing strip: low leakage probability.
Export-compliant docs + salt-spray-resistant paint: verified weather life outdoors.

Key Advantages

True 100mm thickness: stable insulation, clearer long-term energy saving vs. thin panels.
Virgin EPS core: even hardness, no collapse, longer life than recycled-core boards.
Stronger lapped waterproof joint: much lower roof-leak risk.
Export-compliant test docs + salt-spray-resistant coating: proven outdoor durability, cost-effective vs. rockwool.
