PVC strip curtains – L22

The strip curtain is an effective product for insulating rooms in the food industry, cold rooms or food warehouses. It has the advantage of being able to hold in the cold, or heat, whilst allowing relatively easy access.

The strip curtain: a very effective and economical form of insulation!

The L22 strip curtain consists of an exclusive and ingenious hanging rail: covered and closed, it guarantees easy cleaning and better hygiene.

It may comprise transparent crystal flexible PVC strips, or polar PVC strips for the negative temperatures in freezing chambers or even strips certified food safe when direct contact is possible between the strip and the foodstuff.

Technical specifications of L22 strip curtain

The L22 hanging rail (SPENLE innovation)

  • The L22 rail developed by SPENLE is a hanging rail that is particularly suited to the food industry and its hygiene requirements: closed, covered, it is sealed and easily cleaned for better hygiene,,
  • The rail is extremely sturdy and consists of a support bar and studs, on the one hand, and the cover, on the other. The pre-cut and punched strips are positioned one by one on the studs, then covered by the cover, the assembly being held together by wing nuts. It is a particularly effective system and one that guarantees ultra-fast installation.
  • The rail is available in galvanised steel 2 mm thick, in grade 304L or even 316L stainless steel for the most demanding and corrosive environments.

The strip curtain is designed for overlay mounting (on the wall above the opening) or it can be installed under the lintel/ceiling.

Flexible PVC strips

Flexible PVC strips with rounded edges and partial or total overlap. Depending on the type of PVC used, the strips can be 100, 200, 300 or 400 mm wide with thicknesses ranging from 2 to 4 mm.

In the food industry and refrigerated settings, the most common strips are mainly:

  • Transparent crystal flexible PVC strips, which are slightly blue-tinted,
  • Extreme cold or polar PVC strips exclusively for sub-zero temperatures (transparent, very slightly blue-tinted),
  • Food contact flexible PVC strips (transparent, slightly blue-tinted),

There are also other types of special or technical strips (e.g.: flame-retardant, opaque, antistatic PVC, etc.), which are listed in the table below.
