WPTI Press Release - December 15, 2004

Wellington Polymer Technology Inc. is currently in the process of increasing production capacity at its Chatham, Ontario, Canada facility in an attempt to keep up with demand for its Enviroshake® brand roofing product. Enviroshake® is 95% derived from recycled materials such as post-industrial plastics, fiber (flax, wood, hemp), and crumb rubber from tires.

“New equipment is being installed for 2005 which should more than triple the production levels achieved in 2004”, says Brian Eberle, Vice President of Marketing and Sales for the company. “We have a major portion of the first quarter 2005 production already spoken for and a good number of orders are already booked well into the second quarter. We anticipate a very busy and challenging year ahead. Enviroshake® was featured on Bob Vila’s Home Again TV show in January and July of 2004, and was chosen by Popular Mechanics Magazine (June 2004 issue) as one of the 15 best picks of the International Builders Show, held in Las Vegas, Nevada in January 2004. The orders flooded in and we had a hard time keeping up with demand”.

Enviroshake® composite engineered roofing provides homeowners with the best of both worlds, accurately replicating the desirable look of a “silvered” taper-split cedar roof while offering the durability and maintenance free features everyone desires and expects in a quality premium roof. It will not rot, warp, crack or blister and is backed by a 50 year non-prorated and fully transferable warranty. It is resistant to hail, mold, mildew, and insects. The shakes are easy to install on plywood or strapping, can be walked on without risk of damage, require no special tools or fasteners to install, and can be installed using a power-nailer or hammer and nails. Installation is similar to that of cedar however strapping is not required. Custom molded ridge and hip caps complete the look.

WPTI Press Release -- September 11, 2002

Marty Hope - Calgary Herald
An Ontario company hopes sales of its EnviroShake product will got through the roof in Alberta and B.C. “They could, in fact, become our number one markets,” says Dan Warrener, chief executive officer of Wellington Polymer Technology Inc. The Chatham, Ont. firm has come up with a solution to the rotting pine shake roof problem that has hit Alberta. The EnviroShake is a mixture of polymers, plastic, rubber, flax and hemp straw as well as some “secret ingredients,” says Warrener. After being heated in an extruder to 177 C it is squeezed into the shape of shakes under 50,000 kilograms of pressure.

“This product does not rot, crack, warp or shrink and is resistance to insects, moulds and mildew. And, it’s not damaged by hail, high winds or seasonal freezing and thawing, and does not require seasonal maintenance or preservatives,” Warrener explains. The first Alberta installation was scheduled for this week in Edmonton on one of the thousands of homes in the province plagued by the rotting pine shakes. Although homes in the southern part of the province, including Calgary have not been immune to the rot, the problem is most severe in the Edmonton region. Edmonton-based Enercon will be Wellington’s distributor for the shakes in Alberta. “I worked in Edmonton for 15 years and was aware of the problem there and in St. Albert just five years or so after pine shake installations had been completed. This problem has not diminished in Alberta and thousands of homeowners are still trying to come up with an alternative,” Warrener says. Warrener expects to receive Canadian Construction Materials Commission approval this fall for use on new homes. Presently, the product can be used in re-roofing applications.

WPTI Press Release -- May 13, 2002

Jerry Pickard, Member of Parliament for Chatham-Kent Essex, and the Hon. Lyle Vanclief, Minister of Agriculture and Agri-Food, will participate today in the official opening ceremonies of Wellington Polymer Technology Inc. (WPTI) in Chatham-Kent.

WPTI have spent over 6 years developing the EnviroShake - a simulated cedar shake roof covering that integrates reclaimable agricultural fibres with post-industrial plastic bi-products. The EnviroShake product has the shape, texture, and appearance of a cedar roof, but offers the physical characteristics as well as the added benefits of performance and durability associated with a composite material. The EnviroShake is installed as per the Ontario Building Code requirements for the installation of cedar shakes and shingles, however, once installed it is maintenance-free. It is also mould, mildew and insect resistant, wind and hail repellent, and will not crack or warp.

The technology is founded on the tenet that it is possible to create an attractive premium roofing product using reclaimable post-industrial polymers and agricultural fibres, along with good chemistry and ingenuity. The company incorporates such materials as rubber from used tires, post-industrial and agricultural plastics, reclaimable industrial hemp and flax fibres, and other ingredients to manufacture the EnviroShake product. WPTI prides itself on having developed a premium quality and environmentally responsible roofing product. Any scrap materials generated during the manufacturing process are recycled back into the system, and the final product itself is recyclable.

The project received initial federal government funding of $250,000 from the Canadian Adaptation and Rural Development (CARD) Fund through the Agricultural Adaptation Council, which allowed WPTI to further develop a commercial product that is manufactured in Chatham.

In recognition of its outstanding contribution to the vitality of Canada's agri-food sector, Wellington Polymer Technology Inc. was awarded the first-ever Canadian Agri-Food Award of Excellence for Innovation. The award was presented by Agriculture and Agri-Food Minister Lyle Vanclief at the Royal Agricultural Winter Fair in November of 2001.

"Agricultural innovation and entrepreneurship have reached new heights with the EnviroShake," said Minister Vanclief. "Agricultural products are proving useful in areas other than the food sector, and every new product like this opens the door for many more uses of agricultural land. Canada's reputation for excellence is built on achievement at all levels, and I am delighted to witness first-hand the production of this new and truly innovative product," added Mr. Vanclief.

"We are honoured and grateful that Minister Vanclief and Mr. Pickard are participating in the official ceremonies of our new commercial operations here in Chatham," said Dan Warrener, the CEO of Wellington Polymer Technology Inc. "The federal government's support for a new industry like ours has been most reassuring, and we look forward to further developing this unique commercial product in our Chatham operations."

Addendum to Jerry Pickard M.P. Chatham-Kent-Essex -- NEWS RELEASE
November 05, 2001


Wellington Polymer Technology Inc. (WPTI) of Chatham, Ontario was the recipient of the Canadian Agri-Food Award of Excellence for Innovation. Minister Vanclief presented the award to WPTI on Monday November 05, at The Royal Winter Fair's President's Luncheon in Toronto. The Minister praised WPTI for their innovation in the development of the Enviroshake® product, and bringing diversity to the Agriculture sector. WPTI has successfully integrated reclaimable agricultural fibres with post-industrial plastic bi-products in the composition of the Enviroshake® - a simulated cedar shake roof covering. WPTI are now preparing to launch their creation into the North American market in the spring and will focus on the local demand for product as they continue to develop their operations in Chatham.

Jerry Pickard, M.P. for Chatham- Kent Essex, commented that "the agri-food sector is crucial to this country's economy and these awards recognize those who keep us at the forefront like Wellington Polymer Technology Inc. in my riding."

The Enviroshake® - a simulated cedar shake roof covering, offers many advantages over conventional wood products due to the strength, durability, and other inherent physical properties of the WPTI composite material. The final product replicates the look of an antique cedar roof when installed, but will not require treatments or any maintenance, will not warp or crack, and will offer added durability compared to conventional shakes.

Brian Eberle, Director of Marketing and Sales for WPTI, is excited about the future of the company and the product as he notes that " this material is environmentally friendly, produces a premium product, gives real value to the consumer, and most importantly it looks great". He further noted that anyone interested in learning more about the product can access their web site at www.enviroshake.com, or call their toll free number at 1-866-423-3302.
