VKG - Vereniging Kunststof Gevelelementenindustrie - is the trade association for plastic window frames. We stand for valuable chain cooperation for circularity and sustainable quality. Our quality requirements for plastic window frames go beyond the European laws and regulations. When a manufacturer or supplier meets the high standards, the VKG quality mark may be used. Our members offer top products and service.
The four certainties of VKG Keurmerk
As a trade association, we watch over the process and the end products. Window frames and cladding produced, delivered and fitted under the VKG Quality Mark offer four certainties:
Quality
Together we monitor the quality of components throughout the chain. From glazing to certified fitters. The VKG Quality Requirements & Recommendations form the basis for this.
Warranty & Guarantee Fund
Clear guarantees on appointments and down payment by our members, with an umbrella guarantee from VKG Keurmerk.
Control & transparency
Independent audit and clarity and transparency about the contract and terms of delivery.
Sustainability
Focus and control on sustainability in the chain. Longevity and the VKG Recycle System.
VKG Recycling System
The plastic from discarded window frames can be recycled into valuable raw materials for new window frames. For decades, the VKG Recycling System has been collecting old, discarded plastic window frames with the aim of recycling as many frames as possible and thus further increasing the proportion of recycled material in new plastic window frames. Meanwhile, profiles for 35% consist of recycled material. VKG profile suppliers even reach 50%. Old window frames can be handed in to VKG Hallmark manufacturers. For larger construction projects, a container can be placed on the building site through a recycling partner.
Professionals
We highly value professional and certified fitters; only they are allowed to install frames under the VKG Quality Mark. In order to provide new professionals we have set up the Synthetic Window Frame Assembly School together with the ROC. This apprenticeship goes further than sustainable and quality window frame installation, attention is also paid to the future with the circular building economy, technical innovations and prefab construction. We hope to welcome many new fitters, starters and lateral entrants, to our wonderful profession.
