Reduce Edge Leakage in Conventional VIPs: VAP® Aluminum-Based VAP for Multiple Industries

Prefabricated aluminum-plastic base shell eliminates fold-edge damage — balancing high performance with cost for large-scale projects

Professionals working with refrigerators, freezers, cold-chain logistics, ultra-low-energy buildings, and rail-transit insulation face three recurring problems:

Folded-edge vulnerability — Conventional bag-type VIPs require folded edges along all four sides; leakage rates are highest at corners, and a minor transport impact can cause vacuum loss and high project scrap rates
Performance drift — Insulation performance can decline after long exposure to high/low temperatures or high humidity, raising appliance electricity use and building heating/cooling loads
Cost pressure — High-performance vacuum panels are often too expensive for large-volume projects
Project managers need a general-purpose VIP that combines stable performance, long service life, and reasonable cost. Super Tech’s VAP® aluminum-based vacuum insulation panel (VAP-AL) answers that need for most residential and commercial applications from −40°C to 100°C.
