AG-FS Waterproof & Heat Insulation Membrane is an integrated waterproof and thermal insulation material, composed of reflective aluminum film, aerogel insulation layer, self-adhesive waterproof base material, and release film. Effectively solves waterproof and thermal insulation challenges in projects such as metal roof and concrete roof. During the severe rainstorm in Zhengzhou in 2021, warehouses that had used this membrane for roof insulation and waterproofing remained completely unaffected.
Industrial roofs and grain storage silo roofs typically require both reliable waterproofing and effective thermal insulation. Traditional systems often rely on multiple layers — insulation boards, waterproof membranes, vapor barriers and protective layers — which increase installation complexity and construction time.
AG-FS combines waterproofing and thermal insulation into a single self-adhesive membrane system, reducing the number of construction steps while maintaining stable long-term performance.
Simplify roof system structure
Reduce installation complexity
Improve construction efficiency
Minimize potential failure points between layers
Proven in Large-Scale Grain Storage Projects
AG-FS membranes have been widely applied in China Grain Reserves (Sinograin) granary roof projects, covering millions of square meters.
Condensation
Mold growth
Grain spoilage
Pest-related risks
The long-term application of AG-FS in these projects demonstrates its reliability in large-area industrial roofing environments.
High-Performance Thermal Insulation in Ultra-Thin Structure
AG-FS combines nano aerogel insulation technology with a high-reflectivity aluminum surface layer to deliver efficient thermal protection in a thin membrane format.
Uses nano aerogel insulation material
Aluminum surface solar reflectance: 0.82
Membrane thickness: approximately 1.5 mm
Achieves ≥25°C temperature difference in validated applications
This performance means that even in extremely thin construction, the membrane can significantly reduce heat transfer into the building structure.
Reduce internal temperature fluctuations
Lower the risk of condensation
Improve environmental stability inside storage facilities
Enhance overall roof thermal control performance
The combination of low thermal conductivity and high solar reflectivity provides measurable insulation benefits without increasing structural thickness.
AG-FS is designed as a multifunctional roofing membrane, integrating:
Waterproof protection
Thermal insulation
Vapor control
Surface protection layer
By combining these functions into one system, AG-FS reduces the need for multiple material layers, simplifying logistics and installation management for contractors.
The self-adhesive structure of AG-FS allows for streamlined installation in large-scale roofing projects.
Compared with traditional multi-layer systems, it can help reduce:
On-site labor requirements
Installation steps
Overall project timelines
This makes it particularly suitable for large industrial roofs and silo structures where construction efficiency directly impacts project cost and delivery schedules.
AG-FS aerogel waterproof insulation membrane is suitable for:
Grain storage silo roofs
Industrial factory roofing systems
Warehouse roofs
Logistics center buildings
Large-area infrastructure roof projects
It is especially valuable in projects that require both waterproof reliability and measurable thermal insulation performance in a thin structural format.

It integrates waterproofing and thermal insulation. 1.5mm thickness achieves ≥25℃ temperature difference, 2mm ≥33℃, with 0.82 solar reflectance, no need for separate construction.
It excels in extreme heat. The top reflective aluminum film has a solar reflectance of 0.82, blocking 82% of solar radiation. For a 1.5mm-thick membrane, the thermal insulation temperature difference reaches ≥25℃, keeping metal roof surfaces 18-25℃ cooler than uninsulated roofs. Additionally, it maintains stability at 80℃ for 168 hours, no flowing, cracking, or deformation, outperforming traditional asphalt membranes that soften or degrade in high heat.
Installation is simple and no special conditions are needed. The documentation specifies only 3 construction steps: Clean the base → Treat joints, roll back the membrane to the middle, peel off the release film, and paste and compact → Large-area paving (align the overlapping edge with the previous roll during paving, and apply edge-sealing adhesive or polyurethane around the perimeter after overall paving). It also features simple construction, safe operation, short construction period, high efficiency, and no curing required after forming.
