WE SPECIALIZE IN CUSTOM MADE PROJECTION SCREENS TO VIRTUALLY ANY SIZE AND SHAPE.
MANUFACTURING STANDARDS & GUIDELINES
High-frequency welded hook & loop is available, please call for details and pricing.
▸ Dimensions refer to the relaxed, un-tensioned state of the projection screen surface.
▸ Normal Seam Direction is Vertical. In the case of Horizontal Seams, customer assumes all risk. We do not guarantee Horizontal seams as there is adverse stress due to excess weight from the overall size of the screen.
▸ Unless otherwise specified at time of order, all high- frequency welded finished projection screens are folded and packed in a box for transport.
▸ To receive projection screens as wrinkle-free as possible, projection screens must be rolled and shipped on a tube (rolling is an extra charge and must be stipulated by the customer at time of order. Practical limitations on size must be discussed.
▸ In freezing conditions, projection screens must warm up to room temperature before removing from box or unwrapping from storage container.
▸ Our projection screens are intended for interior use only with the exception of Arena 86, which can be used outdoors.
▸ Our projection screens are not recommended for use with any other motorized roller mechanisms other than a Gerriets roller mechanism.
A few facts about PVC projection screens:
Most Gerriets projection screens are made of PVC (polyvinyl
chloride), an amorphous thermoplastic that is white, hard and
brittle until it is treated with plasticizers and stabilizers that
make it a malleable material useable for technical applications.
Additional additives make the material flame retardant.
The physical properties of PVC change with temperature,
which means that PVC projection screens become more supple
under heat and harden when they become cold. It is extremely
important that our PVC projection screens are handled and
installed at ambient room temperature, otherwise irreversible
damage to the screen can occur in the form of tiny cracks in
the material.
Many amorphous plastics, including PVC, form small white
lines when stretched, folded, or otherwise stressed. This
result is called Crazing and creates tiny flaws that normally
are not seen under normal projection conditions. However,
depending upon the severity of the damage, these tiny flaws
can turn into visible cracks in the projection screen.
