These spacer systems make our windows even more energy-efficient, qualifying them as Envirosealed Windows. As important as saving money is, Envirosealed Windows also help you to produce fewer harmful gases, such as CO2.

ENERGY STAR Approved
Clera Windows + Doors products are ENERGY STAR approved. Windows, doors and skylights — collectively known as fenestration products — are a major source of heat loss in Canadian homes. Energy-efficient windows will also increase your comfort, cut down outside noise levels, have less condensation in cold weather than standard products, and allow fewer ultraviolet rays to pass through glazed areas, thus better protecting your valuables from sun damage.

How much money can I expect to save by installing ENERGY STAR® qualified fenestration products?
Homeowners who replace all of their old windows and doors with ENERGY STAR qualified products, such as Clera vinyl windows, will typically save about 7 percent on their energy bills, depending on the number of windows and doors replaced, their age, and how much air leakage was occurring. Buyers of new homes with ENERGY STAR qualified fenestration products can save up to 12 percent on their energy bills compared to standard products — the savings tend to be greater for new homes because they are typically larger and have more windows and doors than older homes.
Strict Technical Requirements
To qualify for the ENERGY STAR mark, fenestration products must meet strict technical requirements for both thermal and structural performance. Products are qualified based on either their U-value (rate of heat transfer from the warm area to a cold area) or their Energy Rating (a scale that takes into account a product's U-value, potential solar gain and air tightness). The colder the climate zone, the more stringent the requirements. Windows, doors and skylights must also have good air tightness to qualify for ENERGY STAR. To ensure the integrity of the ENERGY STAR mark, all product testing is done by accredited laboratories under standardized, quality-controlled conditions.
Independent energy efficiency ratings for Clera vinyl windows are available online from Natural Resources Canada.
