Your self-cleaning windows need rain in order to be cleaned? What if it doesn't rain? A. No problem – if there has been no rain, a simple spray with the hose should restore clean windows. There are several other care recommendations – mostly falling under the category of "getting acquainted" with this remarkable product. For example, if windows were recently installed, it may take up to seven days for the dirt-burning process to be activated. Our self-cleaning glass will last a lifetime but don't expose the exterior glass to harsh chemicals such as silicone. Particular attention should be paid to avoiding sharp or abrasive materials that may damage the treated surface. North Star has published a brochure to assist in the care of this new product. Please consult a North Star dealer about this exciting option. Q. Where can I find a local dealer? A. You can now use our online Dealer Locator. Our dealers are also listed in the Yellow Pages under windows, or contact us at: sales@northstarwindows.com Q. How good is the North Star warranty? A. North Star stands proudly behind its products with a transferable, limited lifetime warranty. The generous protection provided to the original purchaser is extended to a subsequent owner. Please speak with a North Star dealer for details. Q. What if there's a problem with my North Star windows? A. The first step is to contact the dealer who installed your windows. Dealers are familiar with all characteristics of North Star products and install windows and doors according to North Star's stringent guidelines. Your dealer will make an on-site inspection and provide any adjustments that may be necessary. Q. Help! There's a blizzard of groups that test window performance. What do I look for? A. Many groups now assess performance and set standards in order to assist consumers and the industry. But you need a program to know the players. Canadian General Standards Board (CGSB) has an insulated glass unit (IGU) standard assessing durability of window and door sealed units. Canadian Standards Association (CSA) has a voluntary certification program. Independent auditors determine whether windows comply with CSA-A440, The CSA constantly monitors and certifies that North Star's manufacturing and testing process meet or exceed CSA standards. All North Star products are CSA certified. Please contact a North Star dealer for complete details about the certification process and the performance testing results on all North Star windows. Insulating Glass Manufacturers Alliance (IGMA) is a North American association of insulating glass manufacturers, suppliers of component materials and other industry professionals dedicated to upgrading product performance by promoting awareness of technological developments in the industry. Q. What is CSA-A440? And why is it so important? A. CSA-A440 is the window equivalent of a final exam – it doesn't matter how good you say you are because now there's evidence. The Canadian Standards Association established CSA-A440 for windows. It describes how to measure and rate windows for airtightness, watertightness and wind resistance, even susceptibility to forced entry. All North Star windows have been tested – and the excellent results speak for themselves. Be wary of windows that have not been tested toCSA-A440 standards. Q. Why do old windows even need to be replaced? A. There are several factors to be considered. Energy loss: Perhaps 25 per cent of your energy bill is lost through windows. A 3'X5' window with a 1/16" gap around the sashes is like having a hole the size of a brick. Condensation: Energy-efficient windows stay warmer on the interior surface, so humidity can be raised without getting moisture on windows, which can eventually damage walls. Less condensation also helps reduce growth of mould. Air quality: Tight windows keep out dust, bugs, pollen and sound – so the indoor environment is healthier. Q. What's with the "star" logo? A. North Star is a proud partner of Energy Star® and signals we not only build energy-efficient products but that we also use energy wisely – saving money for consumers and protecting the environment for future generations. Energy Star - Canadian Site Energy Star - U.S. Site Q. What is "Low-e" glass? A. Low-e glass has a near-invisible coating that reduces the amount of heat lost while letting in all the light. North Star windows have Low-e as a standard feature. Q. Why should I choose vinyl? A. Vinyl is a relative newcomer but gaining rapidly through advances in energy efficiency, strength and versatility. Vinyl is resistant to moisture, doesn't need painting and has a very good insulating value. Wood windows have similar insulating value but they will warp and rot if not painted, resulting in poor efficiency. Vinyl is an attractive low-maintenance option for renovators and homeowners. Q. Condensation is a nuisance on my old windows but I hear it can also cause damage. Is that true? A. Condensation can be a serious problem. The moisture produced by everyday activities such as cooking and showering shows up first on cool dense surfaces such as windows. Over the long term, this dripping can damage windows and nearby surfaces such as drywall and promote growth of mould, a potential health hazard. One solution is to reduce humidity but levels can't always be lowered sufficiently, especially in the winter when moisture is needed to prevent drying. A better solution lies in the windows themselves. North Star windows feature Super Spacer® technology which boosts window R-values by 30 per cent. The advanced warm-edge technology in North Star windows keeps the glass much warmer so they are less likely to fog.
