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.
