Wood chip covers - optimum energy

Crop farming

A secure covering with Toptex protection fabric for wood chips enhanced the storing of wood chips at a dry and cost effective level. An optimum energy yield is achieved when safely improving the storing of the wood chips before taking advantage of their energy characteristics.

In order to actually gain the optimum energy yield from wood chips as an energy resource, its moisture content must be limited to a minimum. In the absence of effective covering, like Toptex protection fabrics, this would alternatively have to be done by constructing a cost expensive roof structure.

With a safe protection like Toptex, water shedding and respiration of the wood chips are no longer unreachable. Toptex drains off water along its surface, while the wood chips remain perfectly dry* (*only extreme and unusual precipitation can temporarily result in partial moistening of the wood chips). Since Toptex is respirating, the wood chips just easily dry off and moist air that could be cumulated by the warming up of the wood chips themselves can easily penetrate through the fabric resulting in solid temperature below the pile.

Main Benefits

Toptex facilitates the cost efficient outdoors storage of wood chips, thereby the construction of expensive halls or roofs is no longer necessary and saves up the otherwise occurring costs thereof. Additionally, in case of windy weather, Toptex also protects neighbouring properties-the development of dust particles created from the wood chips is significantly reduced.

Furthermore, Toptex can easily be cut into the required sizes. It is made of continuous polypropylene filaments that are not chemically harmful to the environment and tested. The fabric is consequently decay resistant and due to its enhanced UV stabilization of the polymer, thus resulting in a life expectancy of up to 5 years.

It is therefore the combination of the following characteristics that make Toptex the perfect solution to cover wood chips:

  • Toptex allows respiration of the pile
  • Toptex effectively sheds rain water
  • Toptex is proven to be wind resistant
  • Toptex is visually attractive due to its green colour that blends in with the surrounding environment
  • Toptex has a longevity of 5 years
  • Toptex is the most economic while improving the product quality.
  • The positive effect of an effective covering of a wood chips pile with Toptex was also proven by a test carried out by the Bavarian Forestry Institute in Germany.

In short: Toptex is the economic solution for the outdoor storage of wood chips!

The Toptex protection fabric for wood chips cover protection is made from green, continuous polypropylene filament in 200 g/m2 (5.9 oz/yd2) and available in the following sizes:

  • 4 x 50 m (4.4 x 55)
  • 5 x 50 m (5.5 x 55)
  • 6 x 50 m (6.6 x 55)

Convert these sizes easily to other units using this calculator.
