How do impact windows and doors enhance energy efficiency and insulation?
Impact doors and windows are specialty products designed to withstand extreme weather events and forced entry while also providing energy efficiency and insulation benefits.
In regions prone to hurricanes, tornadoes, and other storms, impact-resistant doors and windows are critical for protecting homes and businesses. They utilize layered glass, reinforced framing, and robust hardware to resist damage from high winds, flying debris, storm surges and driving rain. Compared to standard doors and windows, impact products are engineered for superior durability and structural integrity when subjected to the forces of severe weather.
Beyond just storm protection, impact doors and windows also greatly boost energy efficiency and insulation. Multiple panes of glass with airspaces between create an insulating effect to reduce heat transfer through the door or window. Advanced weatherstripping and composite frames with thermal breaks minimize air leakage, helping maintain comfortable indoor temperatures.
By installing Energy Star certified impact windows, households can reduce energy costs by 7-15%, which translates to hundreds in annual savings. Over the lifetime of impact doors and windows, which is significantly longer than conventional products, the energy savings really add up. In addition to efficiency, impact products also provide extra security, noise reduction, and improved aesthetics.
How Impact Windows and Doors Enhance Energy Efficiency
Impact resistant doors and windows have inherent advantages over conventional products when it comes to saving energy:
- Multiple Layers of Glass – Impact products utilize two or more panes of glass separated by an air gap within an insulated frame. The airspace between the panes acts as a temperature buffer zone. More glass layers enhance this insulating effect to improve energy efficiency.
- Energy Efficient Materials – Impact window glass often has a low-emissivity (Low-E) coating that regulates heat flow by reflecting infrared light back toward the source. This reduces heating and cooling loads. Low-E coatings combined with argon or krypton gas injected between the glass panes further improve efficiency.
- Airtight Seals – Multi-point locks and thick weatherstripping around impact door and window frames help prevent air leakage. This maintains comfortable indoor temperatures without wasting energy. The tight seals keep heated or cooled air inside.
How Impact Windows and Doors Enhance Insulation
In addition to energy savings, impact doors and windows also boost a home’s insulation:
- Low-Emissivity Coatings – Low-E window glass coatings not only save energy but also decrease temperature transfer through the glass. This keeps interiors warmer in winter and cooler in summer.
- Airtight Seals – Tight weatherstripping around the frame lowers air infiltration that can lead to drafts and fluctuating temperatures. Impact products are designed to minimize gaps in the frame that allow insulation to escape.
- Insulated Frames – Impact windows and door frames have composite or multi-cavity core materials to lower thermal conduction. Composite frames with interior wood also provide natural insulation.
- Reinforcements – Steel reinforcements to strengthen impact products are thermally broken with plastics or composites so they do not span continuously from interior to exterior. This limits heat transfer through the frame.
Energy and Insulation Benefits in Different Climate Zones
The energy efficiency and insulation benefits of impact doors and windows can pay dividends for homes in most climate zones:
- Cold Climates – The multiple glass layers create an insulating barrier against frigid winter winds, snow, and icy conditions. Low-E coatings and argon gas fills provide excellent insulation when heating needs are high during long winters.
- Hot Climates – Solar control Low-E glass is effective at reflecting infrared heat to reduce solar heat gain from intense sunlight and scorching ambient temperatures. This cuts air conditioning costs in summer.
- Temperate Climates – Outstanding insulation honed for both cold winters and hot summers keeps homes comfortable year-round. Energy efficient impact windows are ideal for transition zones with significant seasonal shifts.
Other Benefits of Impact Windows and Doors
In addition to energy and cost savings, impact doors and windows provide other valuable benefits:
- Hurricane Protection – The impact resistant construction protects homes from high winds, blowing debris, heavy rain infiltration and storm surges caused by hurricanes and tropical storms. Impact products provide peace of mind.
- Noise Reduction – Multi-pane insulating glass and airtight seals help dampen outside noise from traffic, construction, noisy neighbors and other sources. This creates quieter, more peaceful indoor living spaces.
- Enhanced Security – Forced entry resistance deters break-in attempts. The strong glass and reinforced frames make impact products extremely difficult for intruders to compromise.
- Curb Appeal – Narrow, thermally-broken frames give impact windows and doors a sleek, attractive high-end look. This can boost a home’s aesthetics and potentially increase its resale value.
Choosing the Right Impact Windows and Doors
When selecting impact doors and windows, keep these tips in mind:
- Consider climate – Opt for solar control Low-E glass in southern regions to cut cooling costs. Prioritize triple pane glass and gas fills in northern areas for the best insulation during cold winters.
- Consider energy goals – For maximum efficiency, look for Energy Star rated impact products made specifically for your region. Energy Star certification ensures strict energy performance required for your climate zone.
- Consider budget – Impact products do come at a premium cost but pay back over time through utility bill savings, protection, durability and security.
- Choose quality – Look for reputable brands that adhere to stringent testing and meet impact ratings for your area. This ensures authentic structural integrity and performance.
- Hire an expert – Have a professional accurately measure openings, properly specify suitable products, and install them correctly for ideal long-term performance.
Impact resistant doors and windows represent an investment that returns dividends through utility bill savings, weather protection, security, and peace of mind. Compared to conventional windows and doors, impact products provide superior energy efficiency and insulation due to their robust layered construction and advanced materials.
Over the decades-long useful life of impact doors and windows, the energy cost reduction alone makes them a worthwhile home upgrade for most homeowners. Additionally, protection from severe storms provides security and preserves property.
