Cooling the stratosphere has both good and bad effects on ozone destruction, Newchurch said. Cooling the air in the upper stratosphere slows the rate of chemical destruction reactions, thereby increasing the ozone amounts. In the lower stratosphere, cooling also changes wind and air mixing patterns in a way that can increase ozone depletion, especially in high latitudes..
Western Canadians know how harsh our climate can be from frost biting winters to sun blazing summers.So it’s not surprising that a company founded on the Prairies has gained a reputation for manufacturing and installing high quality windows and doors, designed with our changing seasons in mind.From its start in Winnipeg 35 years ago, Polar Ray O Max Windows has grown to become a major supplier of premium products that can add beauty to the home, increase its value and reduce heating bills by up to 25 per cent.Windows and doors are a crucial component in keeping warm air inside during winters, and the heat of the sun outside during summer, and not all new products are created equally.Polar Ray O Max products are manufactured with an eye toward quality during every step of the process.It starts with a high strength steel insert in every window, to create a solid frame that will outlast traditional vinyl frame products.While many companies are content to leave hollow space inside the window frame that can be a source of heat transfer, Polar fills its windows with high density foam.Several choices of high performance glass are available that can reflect up to 90 per cent of radiant heat back to its source, and decrease damaging ultraviolet light entering your home.The triple pane glass units are then filled with krypton/argon gas, keeping the warmth inside a room in winter, and outside in summer.Finally, every Polar Ray O Max window is assembled with Santoprene weather seals, which are thicker than those used by most manufacturers.The end result are windows that will out perform any other operating window, including wood, in terms of longevity, security, overall performance and sustained value.Polar Ray O Max doors share the same level of quality, with door jams and frames made of strong composite materials, high impact steel reinforcement and a solid R 15 core.Doors are available in glass styles or with sidelites that also use Polar’s tri pane glass units for the ultimate in energy efficiency.With many homeowners more environmentally conscious than ever, Polar Ray O Max windows and doors can reduce the number of times your furnace and/or air conditioner cycles on in some cases up to 30 per cent saving you real money on your utility bills.Since even the best products lose their value if not properly installed, Polar Ray O Max has always offered its own installation service for one stop convenience.The craftsmen who install the windows and doors work for Polar Ray O Max and share the company philosophy for quality. They are never contracted out from another firm.Panda: Firm action needed on pipelinesBy Prasad Panda If there’s one thing I hope all Albertans can agree on, it’s the.Flanagan: Alberta can learn big lessons from a small First NationBy Tom Flanagan One of the greatest First Nation success stories is the Fort McKay.Milke: Notley shouldn’t poke fun at the 1990s she should learn from the decadePremier Rachel Notley has a habit of making fake claims about the 1990s, the decade.Snyder: The powerful effort to end homelessness needs your supportBy G.
