What Are The Passive Door Technology Solutions?

The main technical requirements of "passive door" are thermal insulation performance, the index is the heat transfer coefficient K value, the mainstream requirement is that the K value is lower than 1.2 or 1.3, and the airtight performance is above 6.

So what are the common technical solutions?

1 Wood-metal composite "passive door"

With wooden frame as the keel, steel plate, aluminum plate, copper plate and wooden plate as the panel, filled with thermal insulation and fire protection filler, to achieve thermal insulation and fire protection performance.

2 Steel "passive door"

The keel is made of steel profiles with broken heat treatment and filled with thermal insulation and fireproof materials to achieve thermal insulation and fireproof performance.

3 Aluminum alloy "passive door"

Aluminum alloy profile is used as the keel and filled with thermal insulation and fireproof materials to achieve thermal insulation and fireproof performance.

4 Glass "passive door"

Aluminum alloy, plastic, wood, steel and other doors and Windows profiles and high-performance glass, to achieve thermal insulation performance, mostly used in the curtain wall entrance.
