Finished up to 80% faster than traditional renovation
Duplicor® is a sustainable, biobased and lightweight product with a very high thermal insulation value. With the thin sandwich of recycled PET at its core, Duplicor renovation panels are a sleek addition to your existing buildings. Easy to apply and ready to use with the desired finish available from our factory. Your building will be like new again.
Lightweight, fire-resistant, extremely strong and CO2-saving. These are the major advantages of Duplicor® prefab facade and roof elements. The Bio-composite products are made by Holland Composites in Lelystad.
General director Sven Erik explains: ''The bio-composite is composed of biological material. It is made from agricultural residual products such as corn and cane sugar. During the production process, the bioresin is pre-impregnated in natural and glass fibres. This creates the laminate from which the facade and roof elements are formed. The extraction of residual material is not at the expense of existing crops. Our products are the new standard in biobased fire resistant composite solutions.”
Duplicor® is used in both new construction and renovation in non-residential construction and homes. The weight is no less than four times lighter than aluminum constructions and up to fifteen times lower than concrete. The low weight means that less stringent requirements need to be set for the load-bearing capacity of the underlying structure. The composite solution is extremely strong and is therefore used as a constructive and load-bearing element. Due to its low weight, the product is also very suitable for high-rise buildings. Due to the low weight, fewer anchor points are also required.
Insulation value
Despite their low density, the products have a very high thermal and insulation value, which are certainly comparable to traditional materials such as wood or concrete. Holland Composites supplies sandwich elements that "pack" the entire building envelope and have a core made from various recycled materials, including PET bottles, rock wool or cork. In addition to its low weight and high environmental class, the facade shell has other advantages. Janssen: “Because the elements are very thin, more m2 of floor space per floor is achieved with the same gross floor area. This provides the client with considerable savings when it comes to material and therefore money.
According to Janssen, the environmental benefit becomes even greater when you consider that more items can be transported to the construction site due to the light weight per lorry load. The construction hoist can also take more in one go. This means fewer transport movements, so less CO2 emissions.” CE-Delft has studied the environmental effects of Duplicor®. The results are without a doubt positive.
Prefab
The Duplicor® renovation elements are delivered prefab to the construction site, complete with, for example, brick slips and decorative plaster finishing. This means a lot less work for the contractor. The employees only have to position and anchor the elements. This saves them a lot of time and therefore money. Special training for processing is not necessary. The standard instruction is sufficient.
Fire retardant
The facade elements are fire-retardant and are produced according to Euro fire class B S1 DO according to NEN-EN 1350. Janssen: ''The bioresin that is processed in our product is very fire-resistant. The fire resistance of Duplicor® far exceeds the requirements set in the Building Decree."
Design
Composite material is easy to shape and can contribute greatly to the representative appearance of a building. A number of projects bear witness to this. In this context, Janssen mentions, among other things, the Music Palace in Utrecht and The Pulse building currently under construction on Amsterdam's Zuidas, where a complete office facade is being realized with large windows. The student initiative SUM can also be called i.v.m. expansion possibilities of existing social rental flats. Duplicor® elements are also suitable for mounting on monumental buildings for both facade and roof constructions, such as those already realized at the van gendt halls in Amsterdam. It is also possible to install solar panels. In addition, the bio-composite elements are low-maintenance.

Aan de rand van het Dakpark in Rotterdam realiseert Slokker Bouwgroep het project Kop Dakpark: een nieuw woongebouw dat stedelijk wonen combineert met groen, ruimte en leefkwaliteit. Het project vormt een markante entree naar het park en draagt bij aan de verdere ontwikkeling van Delfshaven als aantrekkelijke woonomgeving.
Voor Woonzorg Flevoland realiseert QBIX een moderne woonzorgomgeving waarin comfort, duurzaamheid en leefkwaliteit centraal staan. Het project is gericht op het creëren van een toekomstbestendige zorgomgeving, met oog voor zowel bewoners als de directe leefomgeving.
De ambitie om duurzaam te verbouwen leeft breed in de bouwsector. Energiezuiniger, circulair en toekomstbestendig bouwen wordt steeds vaker als uitgangspunt genomen; juist ook bij renovaties. Maar in de praktijk blijkt duurzaam bouwen vaak complex, zeker als het gaat om bestaande gebouwen die niet ontworpen zijn voor de normen van nu. In die zoektocht krijgt bio-composiet materiaal een steeds grotere rol.
