Flashspun Hypak™ For Cold Storage Floor With Insulation Vapour Barriers

Greater Cold Storage Airtightness, Lower Cold Storage Energy Consumption

The internal temperature of the cold storage is generally -30℃~-10℃, which is very different from the outside temperature, so it is easy to form condensation water.

Therefore, the envelope structure of rigid wall insulation with insulation vapor barriers should have good thermal house wrap and insulation and waterproof functions.

Flashspun Hypak™ Ensures Flexible Vapor House Wrap Insulation Management System

Waterproof & Breathable

The water vapor of the air always permeates from the high-temperature side to the low-temperature side. A special air house wrap insulation vapour barrier membrane for cold storage is arranged on the high-temperature side of the rigid insulation vapor barrier layer, while Flashspun Hypak™ waterproof & breathable material wall insulation vapor barrier with strong hydrophobic and breathability is arranged on the low-temperature side, weather smart building wrap can not only prevents water vapor from entering the wall insulation vapor barrier layer but also allow the water infiltrating into the insulation vapour barrier to diffuse.

Reduce Energy Consumption

The combination of dredging and blocking can avoid the accumulation of water vapor in the envelope, keep the insulation layer dry, reduce the probability of cold bridge formation and the frost heave damage probability of the insulation layer, improve the insulation capacity of buildings and reduce energy consumption.

How does Hypak™ work?

Water vapor naturally moves from areas of high temperature to areas of low temperature. With a special air barrier membrane on the warmer side of the thermal insulation and the hydrophobic, waterproof, and breathable Hypak™ on the colder side, water vapor is prevented from entering the insulation and any water that has infiltrated the envelope gets to disperse. Dispersing and blocking simultaneously stops water vapor from gathering in the envelope, keeps insulation dry, reduces cold bridge formation, minimizes freezing and expansion damage of the insulation, boosts building heat preservation and cuts energy consumption.

Challenges for the Cold Storage

At present, there are more than 100,000 cold storage facilities in China, and the number is still growing. Cold storage facilities typically operate at internal temperatures ranging from -30°C to -10°C, resulting in a significant 60°C temperature difference across the building envelope. To ensure optimal performance and minimize energy consumption, the envelope of a cold storage facility requires excellent thermal insulation and moisture-proofing capabilities.

Great Airtightness

The combination of a vapor barrier material and a waterproof and breathable material can meet the stringent airtightness design requirements of cold storage, lower the temperature fluctuation inside, reduce cold bridges, support better cold preservation and improve the economics of a building

Vapor Barrier

The permeability of vapor barrier material is less than 1.5g/m² per 24 hours, which effectively blocks the penetration of water vapor into the thermal insulation on the high-temperature side of the cold storage envelope. At the same time, the waterproof and breathable Hypak™ membrane realizes water repellency while dispersing the water vapor, which keeps the insulation dry and avoids condensation, freezing and expansion

Heat Radiation

Reflection Properly processed Hypak™ offers enhanced insulation properties for cold storage building envelopes by effectively reflecting heat radiation, exhibiting high reflectivity up to 90% when it comes to the near-infrared spectrum.

Highlights of Flashspun Hypak™ in Cold Storage Floor With Rigid Insulation Vapor Barriers

Waterproof & Breathable
Reflective air waterproof and eco-friendly wall insulation vapour barrier membrane: blocks most of the water vapor
Waterproof breathable rigid wall insulation vapor barrier membrane: allow a small amount of water vapor to pass through.
Highly Reflective
After processing of flashspun fabric, Flashspun Hypak™ house wrap insulation with vapor barrier can effectively reflect thermal radiation (near-infrared reflectivity up to 90%) and enhance thermal rigid wall insulation vapor barrier performance.
Vapour barrier and breathability
The water vapor permeation of the vapor rigid wall insulation with vapor barrier material is less than 1.5 g/m2 24h, which can effectively block the water vapor permeation from the high temperature side of the cold storage to the house wrap insulation layer; the Flashspun Hypak™ water resistive and vapour permeance house wrap insulation barriers can realize waterproofing and allow water vapor to be discharged smoothly, keeping the rigid insulation with vapor barrier layer dry and avoiding condensation and frost heaving.
