Safety campaign Polyplastic windows

Campaign performed by:

Fa. POLYPLASTIC acrylic solutions
Vlaardingweg 98
NL – 3044 CH Rotterdam

Short description

Lately we (Polyplastic) have been informed by many authorised dealers in Europe that certain windows show detaching defects. Polyplastic had the presented windows examined in its laboratory. These examinations showed that the full‐pressure windows with colour number 62 that were produced in the time from 1 March 2004 to 31 December 2005 may detach under very special conditions.

Affected vehicles:

Vehicles of the following years of manufacture may be affected by one of the safety campaigns:

  • 01.03.2004 – 31.12.2005 KNAUS
  • 01.03.2004 – 31.12.2005 TABBERT
  • 01.03.2004 – 31.12.2005 WILK
  • 01.03.2004 – 31.12.2005 WEINSBERG
  • 01.03.2004 – 31.12.2005 T@B
  • 01.03.2004 – 31.12.2005 EIFELLAND

What to do:

Owners of affected vehicles have been or will be, as far as possible, informed by writing by KBA or Polyplastic. However, many vehicle owners in foreign countries and owners of not registered vehicles cannot be determined. We therefore ask you to please also inform your camping friends about this safety campaign.

If you should not have received such written information, you can check here whether your vehicle is affected by the safety campaign by way of your chassis / body number.

Examination of the vehicle

The responsible Polyplastic service partner will contact you after you have entered your data and your option on this website.

Information of Knaus Tabbert GmbH:

Knaus Tabbert GmbH has decided to support customers of Knaus Tabbert Group GmbH (i. l.) with respect to this safety campaign. For our customers we, together with Polyplastic, offer to replace the windows or repair them at especially favourable conditions. Unfortunately Polyplastic (the supplier of the windows causing the safety problems) as the company responsible for the safety campaign did not agree to replace the windows fully free of charge.

However, when the windows are replaced the customer will receive new high‐quality windows with corresponding warranty from Polyplastic.
