The function of smoke curtains (along with other elements) is controlling movement and/or accumulation of smoke and heat. Smoke curtains can accumulate smoke and gases at a temperature exceeding up to 600 degrees Celsius, but they should not be confused with fire separation. Curtains are primarily to prevent free spread of smoke and fire gases in rooms with large surfaces – such as warehouses, halls etc. Due to their important role in the fire protection system, their selection should be the responsible designer of the object who will choose the curtain for their specific use.

| 1,00 | 0,055 |
| 1,50 | 0,083 |
| 2,00 | 0,110 |

Constant T35KD smoke curtains are attached to the upper edge to the supporting structure with the help of self -controllers. The support structure must have the required fire resistance class, resulting from the fire resistance class of the building. The attachment takes place with a minimum of two connectors, and the sheets forming the curtain are sewn with self -connectors.
The manufacturer’s technical requirements regarding the mounting elements are presented in detail in the T35KD assembly instructions, with the manufacturer allowing the use of connectors with not worse fire and mechanical properties from the recommended ones.
In the event that the entire curtain has a different shape than a rectangle and when the last fastened sheet cannot be installed in full, it is necessary to cut the sheets. For cutting sheets, use electric scissors with a rotating head. After the installation, it is absolutely cleaned of the surface of filings, screws, etc. In the event of damage to the surface, the necessary (point) retouching should be made as soon as possible, using the appropriate varnish with the original color of the sheet metal. When using a grinder, complaints will not be included.
Note: regardless of the manufacturer’s assembly recommendations for the design of the curtain sheet fastening to the structure and the design of the structure itself, to which the curtain is to be fastened, the designer of the object is responsible. Pruszyński Sp. z o.o. It can be supported by designers in the field of technical consultations for a given project.
In the case of smoke curtains T35KD Pruszyński sheet production, assembly is based on two stages-sewing sheets between each other and fixing sheets to the structure.

A) stitching sheets among themselves
Connect sheets
Type of connector: Self -made connectors WSBP Production Klimas Sp. z o.o. with dimensions: 4.8 x 19 mm from SAE1022 steel
Method of attaching connectors according to the manufacturer’s data
Note: other connectors with not worse fire and mechanical properties are allowed.
B) Fastening sheets to the structure
In the case of receiving its own means of transport, the car should have an open loading platform for free loading and unloading. Galvanized and aluminum sheets must be protected against wetting!
“Manual” unloading should be carried out by the right number of people, i.e. such so as not to move the sheet metal, not bend the side edges and not stretch them. Deformation of sheets during unloading and carrying causes later problems with their proper assembly (gaps on locks, which can cause a curtain leak). The most suitable is unloading in the manufacturer’s packaging using mechanical devices.
