ACRYLIC®
SDP®DOUBLE - SKINNED
Twinwall sheets for many uses.
Distributed by USGR since 1980.
No other material performs like their impact modified sheet
To say that we're extremely happy even thrilled with the new CYRO ALLTOPTM
acrylic sheet would be an understatement," says John R. Newland, co-owner
at Newland's Flowers Limited of Leamington, Ontario. "After installing
the sheeting on our latest greenhouse
in September 1995, we're already seeing significant gains in terms of energy
conservation, and improved plant performance."
There's plenty of growing history behind John's statement. Founded by his
grandfather H.B.Newland in the late 1920s, the company started out as a multiple
operation producing a wide range of vegetables, fruit and flowers. "In
the mid 1960s, we more than doubled our greenhouse
capacity. Today there is 100,000 square feet, all of it used for growing roses."
Even more remarkable, ALLTOP acrylic sheet, a double-walled product, delivers
up to 91% sunlight transmission in the visible range. No other double walled
thermoplastic sheet matches this performance.
"I'm sure one reason is that ALLTOP sheet has wide cells and therefore
fewer support ribs and that lets more light in. And ALLTOP sheet produced
light is much more diffused, which means it reaches more of the plant particularly
among mature growth whiter shadows can be an issue."
ALLTOP sheet has another feature the Newlands are pleased about: more then
50% energy savings compared to single pane glass.
"We have environmental computers constantly monitoring temperatures
along with how long the steam valves are open to heat our greenhouses.
Again, comparing greenhouses that are almost exactly the same size, you can
look at the computer records and see that ALLTOP sheet conserves heat far
better. And as an added bonus, the ALLTOP acrylic sheet greenhouse tends to
be a bit cooler in the summer, since the direct sunlight is diffused."
ALLTOP acrylic sheet's unique on line. NO DRIP®
coating also disperses droplets of rain water and condensation in to a film.
The result is an acrylic sheet that is cleaned by rain, remains transparent
in a drizzle and dries more quickly than glass with minimal spotting. Even
condensation remains virtually invisible.
ACRYLITE® FF and ACRYLITE® G P
CYRO employs two methods of manufacturing ACRYLITE® acrylic sheet. ACRYLITE®
GP acrylic sheet is made by the traditional cell-cast method. ACRYLITE®
FF acrylic sheet is made by CYRO's proprietary continuously manufactured method.
Continual improvements in technology, combined with manufacturing expertise,
make ACRYLITE sheet the benchmark for quality in the industry today. ACRYLITE
sheet, regardless of how it is manufactured, shares the following dependable
high-quality characteristics.
Impact Resistance: ACRYLITE sheet is significantly more shatter-rcsistant
than glass, with many times the impact strength, and is
available in a special bullet-resistant thickness.
Lightweight: ACRYLITE sheet is half the weight of glass and only
44-k as heavy as aluminum.
Optical Clarity: ACRYLITE sheet provides excellent light transmission
and high optical clarity even after prolonged exposure to sunlight.
Weather Resistance: Neither rain. nor sleet, nor snow will damage
skylights made from ACRYLITE sheet. Colorless ACRYLITE sheet
resists the degradation caused by ultraviolet light and comes with a 10-year
limited warranty against loss of light transmission.
Easy to Work With: Saw, cement, drill, rout, thermoform, laser cut,
paint or silk-screen; construction detailing is easy with ACRYLITE sheet's
predictable and consistent properties.
Chemical Resistance: ACRYLITE sheet strongly resists many chemicals
including ammonia, dilute acids and aliphatic hydrocarbons.
Storage: Store masked ACRYLITE sheet away from direct sunlight or
heat. Exposure may make the removal of masking paper difficult.
Handling: Leave masking on ACRYLITE sheet during handling to protect
the sheet surface. Refer to CYRO's "Working with ACRYLITE Acrylic Sheet"
handbook or fabrication briefs for suggestions on cutting, drilling, finishing,
forming, bending, joining and installing this material.
Cleaning: To clean ACRYLITE sheet, use a mild soap (dishwashing liquid)
and water solution. Wipe with a soft cloth. For further details consult our
pamphlet "Caring for ACRYLITE Sheet."
Physical Properties: See our "Physical Properties of ACRYLITE
Acrylic Sheet" brochure.
Expansion and Contraction: Like most plastics, ACRYLITE FF and GP
sheet expands and contracts three to eight times as much as glass or metals.
Allow for size variation in frame systems and other fixtures. A 48" panel
expands or contracts about 0.002" for each °F change in temperature.
In outdoor use, where summer and winter temperatures differ as much as 100°F,
a 48" sheet expands and contracts almost 3/16" (0.19"), or
approximately 1/8"from mid-temperature conditions. Calculate expansion
and contraction allowances from your installing temperature measurements.
Gasketing materials must be chemically compatible with ACRYLITE sheet.

Fire precautions: SDPdouble skinned sheets are produced from molding
compounds which are combustible thermoplastics. Precautions used to protect
combustibles from flames and high heat sources should also be observed with
these materials. SDP sheets usually burn rapidly to completion if not extinguished.
The products of combustion, if sufficient air is present, are carbon dioxide
and water. However, in many fires, sufficient air will not be available and
toxic carbon monoxide will be formed, as it will from other common combustible
materials. We urge good judgement in the end use of these versatile materials
and recommend that building codes be followed carefully to assure they have
been used properly. Access panels may be required for evacuation and venting
of rooms glazed with SDP sheets. SDP sheets burn more rapidly than their solid
counterparts. Non-combustible end caps must be used to prevent flame from
contacting the open ends of SDP sheets.
Very specific installation is required on all twinwall
materials because of expansion and contraction. Extrusions required, along
with special closures suggested instructions available on request.
