Abstract:
IMAG has worked out a research-programme in co-operation with other specialized institutes, to develop the specific characteristics of insulating greenhouse cladding materials.
During the symposium will be reported about the research on plastic channel-section panels and on plastic films.
The following aspects will be indicated:
- a calculation procedure together with measurements of the insulation value
- the resistance against hail
- the strength and stiffness
- the transmissivity to diffuse and perpendicular light
- the diminution of both the strength and the light transmittance through accelerated ageing tests
- the vapour permeability.
