At DASH®, everything we do is driven by a single vision: to help Greek families live better and to create the spaces they use every day at home, in the kitchen, the living room and the bedroom.

At the same time, we choose to take particular care of the environment and to contribute as far as we can to eco-friendly building. Some building materials, kitchen furniture among them, now carry a form of eco-label, which gives consumers some assurance of the product’s environmental credentials. Such labels may be awarded by national and intergovernmental bodies, or by independent non-governmental organisations.

Wood is the most important renewable raw material used as a building material. It requires relatively little processing, so the production process is relatively clean and consumes little energy. However, choosing wood as a building material should also take into account a number of further parameters that determine whether wood can truly be called an “eco-friendly” material. These are:

– The origin of the timber and the way the forests are managed.
– How the wood is treated, and in particular whether or not preservatives are used.
– The energy required for transport.

Wood as an Eco-Friendly Building Material

To build a complete kitchen, DASH® uses wood products such as particleboard (chipboard), fibreboard (MDF) and melamine, with almost zero formaldehyde emissions (E1-class particleboard and fibreboard). All the doors of DASH models are covered with various types of polyethylene film rather than PVC (polyvinyl chloride, commonly known as vinyl).

In addition, two of our kitchen ranges use eco-friendly lacquers to paint the doors.

Below, we provide some information about the types of timber most commonly used in furniture making.
