Energy Efficient Windows & Doors

affiliates energy

Sealing and insulating the "envelope" of a home - its outer walls, ceiling, windows, doors, and floors - is often the

most cost effective way to improve energy efficiency and comfort. Energy Star estimates that a knowledgeable homeowner or skilled contractor can save up to 20% on heating and cooling costs (or up to 10% on their total annual energy bill) by sealing and insulating.

A survey conducted for the National Association of Home Builders (NAHB) confirms that a desire for greater energy efficiency drives consumers to choose a green-built home. Home buyers choose energy efficiency as a motivator because of the rising costs of heating and air conditioning bills.

Windsor WindowUsing Energy Star window and door products can help earn rating points for LEED, the NAHB Model Green Home Building Guidelines or other rating systems. Note that these rating systems vary with their requirements but, overall, they strive toward similar goals. As an Energy Star Partner, Horner can help by supplying you with energy efficient windows and doors for your projects, designed to fit your budget and application.

Captiva Wood Doors

Captiva Doors are built the way craftsmen have been making doors for centuries using only natural wood, a material that cannot be reproduced by synthetic substitutes. Wood is the world's most renewable, sustainable and environmentally friendly building material available. Wood is non-toxic, uses less overall energy than other products, it is recyclable and its growth and replanting removes carbon dioxide from the environment.

The core of Captiva doors is constructed using finger jointed blocks of eastern white pine that minimizes waste and is locally harvested. Veneer construction allows us to maximize the yield of the hardwood faces required for the door. When selecting our lumber for Captiva Doors, we have always purchased lumber from sawmills that we feel harvest lumber using sound forestry practices. For customers that require lumber certified by the Sustainable Forest Initiative® (SFI) or the Forest Stewardship Council© (FSC), those sources are available in our Captiva Door line.

Responsible Forestry by WindsorOne

Windsor Mill practices green manufacturing from the source of the product through production and onto the final sale. Their green building practices begin with their raw materials. Since their founding, Windsor Mill has followed responsible forestry management practices and quality control at all stages of raw material development. Such tight quality control is possible because they own a portion of the Chilean-source forests. Raw materials are harvested from plantation grown sustainable timber stands. All knots and defects are removed from the raw lumber and sent to pulp mills for a range of applications. Throughout the production process, resources are managed to reduce, reuse and recycle waste. WindsorONE trim boards and moldings meet LEED certification requirements and received the Scientific Certification Systems (SCS) Indoor Advantage Gold certification, the most stringent indoor air quality (IAQ) certification in the industry.
