Galvanized Insulation Board Construction Solutions
Q1: Why does galvanized insulation board appear surface rust after installation?
A: Most on‑site rust issues stem from scratched galvanized layers, unprotected cutting edges or unqualified sealing. Construction friction and improper cutting damage the anti‑rust layer, leading to rapid oxidation in humid air. SAMZOON provides standardized edge sealing treatment solutions and on‑site construction guidance to avoid rust risks.
Q2: What causes core peeling and delamination of galvanized insulation board?
A: Core peeling is mainly caused by poor bonding technology, violent extrusion during transportation, or uneven keel force after installation. Unbalanced pressure will separate the galvanized sheet from the inner insulation core. SAMZOON strictly controls composite bonding technology and supports customized packaging to reduce damage.
Q3: Why does heat leakage occur on the splicing joints of galvanized insulation board?
A: Heat leakage is caused by unreasonable gap reservation, discontinuous sealant or mismatched auxiliary accessories. Unsealed gaps form thermal bridges, destroying the overall thermal insulation performance of galvanized insulation board. Standard joint sealing procedures are essential for energy‑saving projects.
Q4: How to solve board bulging and deformation after long‑term use?
A: Panel bulging results from forced assembly without thermal expansion gaps or damp core material due to poor edge sealing. Temperature changes and internal moisture accumulation will deform the whole panel. Reserved expansion gaps and full edge sealing can effectively avoid this defect.
Q5: Can on‑site cutting cause hidden dangers for galvanized insulation board?
A: On‑site cutting exposes the inner core and destroys the original closed protection structure. Unsealed cut edges absorb moisture, breed mildew and cause core rotting. SAMZOON recommends factory pre‑fabrication and provides professional edge sealing treatment standards for necessary on‑site cutting.
Q6: How to avoid secondary damage during later cleaning and maintenance?
A: Hard tool friction and corrosive detergent will scratch the galvanized layer and trigger secondary rusting. It is necessary to adopt soft cleaning methods and neutral detergents. SAMZOON provides complete daily maintenance guidelines for long‑term stable use of galvanized insulation board.
✅ Industry Professional Summary Most failure cases of galvanized insulation board in engineering projects are caused by non‑standard construction rather than product quality defects. Standardized cutting sealing, reasonable gap reservation and anti‑scratch protection are the core keys to ensure long‑term service performance.
