Fire | Smoke

The long-running favorite in our product portfolio.

Fire protection is considered the supreme discipline among performance characteristics, because the main focus here is on protecting people. The behavior of the door in the event of a fire must ensure that those fleeing have enough time to get to safety.

We make no compromises when it comes to the appearance of the door, because the HoSta door has a consistent appearance, even when fire protection properties are required. Tested according to the European standard EN 1634-1.

The main danger in the event of a fire is smoke development. This produces smoke gases that can cause life-threatening poisoning. It is crucial that the door has the appropriate properties to fulfil this purpose in an emergency. Tested according to the European standard EN 1634-3

Facts

Depending on customer requirements, our products are used as interior doors, exterior doors, interior gates or exterior gates. Both national and European standards apply to the certification of these variants. In this article we would like to inform our customers about the current situation:

Inner doors

Interior doors are subject to the national approval procedure. The approval of the doors is issued by the DIBT and the marking is carried out in accordance with the applicable national specifications. Approved products receive a general building approval (AbZ). The resulting characteristics that must be met are:

Fire protection (T30, T90) according to DIN 4102-5
Smoke protection (RS-1, RS-2) and/or tight-fitting
Tested self-closing 10.000 cycles (flaps) and 200.000 cycles (doors)
Material: Elo galvanized and primed, painted steel, stainless steel
Regular external monitoring

Exterior doors | external gates | internal gates

A closure is located outside precisely when the external wall is exposed to direct weathering and/or separates the outside climate from the living space climate. External doors are subject to the European harmonized product standard EN 14351-1. Gates are subject to the standard EN 13241. In addition, Hodapp GmbH & Co. KG has test certificates from accredited institutes (Certificate of Performance), so that the manufactured door products can receive a corresponding CE marking.

Characteristic performance properties regulated by the product standards EN 16034 and EN 14351-1:

Fire protection (EI2-30, EI2-60, EI2-90) according to EN 1634-1 / EN 13501-2
Smoke tightness according to EN 1634-3 / EN 13501-2
Self-closing (10.000 cycles (gates, flaps) and 200.000 cycles (doors)) according to EN 1191 / EN 13501-2
Durability

Different performance characteristics "Smoke protection" according to EN 16034:

Cold smoke tightness (Sa)

Leakage: ≤ 3m³/(hxm) at ∆25Pa
Test temperature: ambient temperature
Threshold is not taken into account

Hot smoke tightness (S200)

Leakage 1-leaf closures: ≤ 20m³/h at ∆50Pa
Leakage 2-leaf closures: ≤ 30m³/h at ∆50Pa
Test temperature: 200

Product testing

We are constantly expanding our product portfolio through regular product testing, which requires months of development work and considerable financial investment.

Fire protection tests are particularly demanding and are supervised by qualified experts and carried out in special testing institutes.

We have our own furnace for internal testing. During the tests, the door is exposed to temperatures of up to 1.300 °C and the temperature on the side facing away from the fire is monitored to ensure that specified maximum values are not exceeded.

The fire resistance behavior is optimized through the use of high-quality materials and specialized insulation methods, which are individually implemented in the company's own production.
