Isoclair™: The solution for improved climatic control
Galvanized steel gutters, given their large surface area and greenhouse-top location, are starkly exposed to direct solar radiation. Significant temperature increases in the gutters have been known to climb to 100°C in extreme cases (especially at altitude).
The sizeable heat increase in the gutters elicits a number of negative
impacts. Firstly, the substantial temperature rise inside the
greenhouse, caused by heat radiation, triggers an adverse effect on the
produce. Secondly, the durability of the plastic film in contact with
or close to the gutters is considerably reduced, causing the film to
soften, bake and then melt in proportion to the temperature increase.
The Product Marketing Department at Filclair has spearheaded research
to minimize heat impact. Since the dimensions of the gutters play a
crucial role in structural resistance and rainwater runoff, it was
essential to find a solution that did not tamper with these dimensions.
The outcome of this research is the new Isoclair™ gutter made from
construction quality galvanized steel, white lacquered with polyester
resin on both sides. This innovation offers the following advantages:
The double-sided coating considerably reduces heating within the
gutters and consequently lowers the inside temperature. This reduced
heat exposure generates marked improvements in the quality and yield of
the produce.
- Increased durability of the plastic films in contact with or close to the gutters.
- The double-sided white coating significantly increases the level of
light diffusion in the greenhouse and triggers improvements in the
quality and yield of the produce.
- The white lacquering process used to produce the plastic coating eliminates any risk of corrosion.
