Vacuum Insulation Panel
An ultra‑high‑efficiency insulation material composed of an inorganic core (fumed silica/glass fiber), a high‑barrier composite film, and an getter, which is vacuum‑sealed to form the final product. By evacuating the cavity to eliminate air‑borne heat conduction and convection, only solid‑state heat conduction remains, resulting in a thermal conductivity far lower than that of conventional insulations. It serves as the core insulation material for nearly zero‑energy buildings and passive houses.
Performance Metrics
1. Fire Performance: Class A1 (Non-combustible)
2. Thermal conductivity: ≤0.008 W/(m·K) (at 25°C)
3. Bulk density: 160–200 kg/m³
4. Vacuum level: ≤1 Pa (at factory)
5. Water vapor transmission rate: ≤0.1 g/(m²·24 h)
6. Compressive strength: ≥0.2 MPa (at 10% deformation)
7. Operating temperature range: -50°C to 80°C
8. Service life: ≥25 years (vacuum decay rate ≤5% per year)
Scope of Application
1. External wall insulation for passive houses and nearly zero-energy buildings.
2. Energy-efficient renovation of historic and traditional buildings (reducing the thickness of insulation layers to preserve their original appearance).
3. Exterior wall insulation for high-end residences and villas (saving usable floor space).
4. Insulation for cold-chain logistics vehicles and refrigerated containers.
5. Insulation layer of household appliances (refrigerators, freezers).
Product Advantages
1. Exceptional thermal insulation performance: with a thermal conductivity of only 0.008 W/(m·K), it outperforms conventional insulation materials by a factor of 4 to 6.
2. Space-saving: With equivalent thermal insulation performance, its thickness is only 1/5 to 1/8 that of conventional materials, increasing the usable floor area by 3% to 5%.
3. Fire Safety: Class A1 non-combustible, with no flame spread and no toxic smoke, meeting the highest fire‑safety standards.
4. Long service life: Featuring a high-barrier film and an oxygen scavenger, it effectively prevents air ingress, with a service life of ≥25 years.
5. Significant energy savings: Helps buildings meet Passive House standards, reducing heating and cooling energy consumption by more than 70%.
Instructions for Use
1. Design and Layout: Arrange the panels in advance according to the wall dimensions to minimize the number of panel joints, ensuring that the joint spacing does not exceed 1 mm.
2. Substrate requirements: The substrate’s flatness deviation shall not exceed 2 mm per 2 m, and it must be treated with a dedicated leveling mortar.
3. Interface Treatment: Apply interface mortar on both sides.
4. Bonding Installation: Use a dedicated bonding mortar (tensile bond strength ≥ 0.6 MPa), applying full‑surface bonding with a mortar thickness of 3–5 mm.
5. Anchorage and Reinforcement: After 24 hours of adhesive application, install plastic expansion anchors at the slab joints, with a minimum of 6 anchors per square meter (for buildings longer than 20 meters, a minimum of 8 anchors per square meter is required).
6. Protective Layer: Apply a 3–5 mm thick layer of specialized lightweight finishing mortar (density ≤ 1200 kg/m³), embedding an alkali-resistant fiberglass mesh fabric.
7. Finished-product protection: Do not puncture or compress; avoid contact with sharp objects during installation; and keep the product out of rain for 7 days after installation.
