Impact windows, known for their strength against stormy weather, have another significant advantage. They can play a pivotal role in making your home more energy-efficient. But how do they do this? Let’s dive into the world of impact windows and discover how they contribute to energy conservation.
Understanding Impact Windows
Before delving into their energy efficiency, acquiring a foundational understanding of what impact windows are, their composition, and their functional mechanism is essential.
What Are Impact Windows?
Impact windows, commonly referred to as hurricane windows, are specially designed and constructed window models that safeguard your home against extreme weather conditions. These windows consist of two layers of tempered glass or special composite layers, coupled with a protective interlayer made from Polyvinyl Butyral (PVB) or Ethylene-Vinyl Acetate (EVA). This interlayer augments the window’s strength, preventing it from shattering into dangerous shards during harsh climatic conditions like hurricanes, storms, among other high-pressure situations. Notably, these windows also offer soundproofing, UV protection, and yes, they contribute significantly to your home’s energy efficiency.
How Impact Windows Work
Understanding the operational mechanism of impact windows provides insights into why they’re highly energy-efficient. Initially, their robust construction aids in the prevention of air leaks, a common issue in standard windows that leads to an immense loss of heated or cooled air. Consequently, you have a regulated indoor temperature, saving you a substantial amount on your energy bills.
Secondly, the interlayer in impact windows acts as an effective insulator, curbing heat transfer while preserving the indoor temperature. In summer, it inhibits heat from creeping into your home, whereas in winter, it keeps the heat inside, again reducing the amount of energy your HVAC system expends to maintain a comfortable climate in your home.
Lastly, the UV protection offered by impact windows adds to their energy efficiency profile. They block almost 99% of UV rays, supposedly the culprits behind solar heat gain inside your house. By keeping out these solar radiations, the indoor temperature remains steady, thereby reducing your cooling costs during warm seasons.
By comprehending the aspects mentioned above, a clear picture forms about how impact windows are not merely protective features, but also valuable energy-saving components in your home.
Assessing Energy Efficiency
Considering the benefits of impact windows, it’s crucial to examine their energy efficiency features. This part of the article will discuss three primary characteristics: insulation capabilities, UV protection and the role of Low-E coatings.
Impact Windows and Insulation
Impact windows effectively enhance a home’s insulation against outside temperatures, keeping internal spaces comfortable. These windows include dual layers of toughened glass and sturdy interlayers, a structural composition that serves as a robust barrier. They stop outdoor air from infiltrating your home and prevent conditioned air inside from escaping. Owing to this, you can count on minimal air leakage, making your home more energy-efficient. Consequently, your air conditioning or heating loads lighten, enabling potential savings on energy bills.
Impact Windows and UV Protection
Beyond insulation, impact windows serve another valuable function: UV protection. These windows come engineered with materials that block up to 99% of UV rays, thus protecting interior furnishings from fading and your skin from harmful exposure. Notebook, such UV blocking capabilities are not merely beneficial from a health and maintenance perspective, but also regarding energy efficiency. By curbing unwanted heat gain associated with UV radiation, these windows help maintain a steady indoor temperature, thereby reducing the need for constant cooling.
The Role of Low-E Coatings
Lastly, let’s not forget the integral role of Low-E (low emissivity) coatings in enhancing the energy efficiency of impact windows. Applied thinly on the glass surfaces, these coatings selectively block certain types of light and heat waves. For instance, they reflect the sun’s heat back outside during warm weather, keeping your home cooler. Conversely, in cool weather, they hold back heat inside the house from escaping, contributing to a warmer interior. This intelligent reflection and retention of heat, depending entirely on the climate’s demands, underscore their contribution towards a more energy-efficient home.
Impact Windows and Energy Savings
Impact windows provide significant energy savings, a benefit often overlooked in favor of their primary function – safeguarding homes and businesses during severe weather conditions. These energy savings come from various properties of impact windows, including their insulation capabilities, Low-E coatings, and UV protection.
Reducing Heating and Cooling Costs
Impact windows offer exceptional insulation, which plays a vital role in managing heating and cooling costs. Their robust construction effectively prevents air leaks, eliminating drafts and keeping your home’s interior temperature consistent. In warm weather, they minimize the influx of heat, reducing the need for air conditioning. Similarly, during the cooler months, they prevent warm indoor air from escaping, ensuring that your heating system doesn’t overwork. These attributes successfully bring down overall energy consumption, usually reflected in less inflated utility bills.
Environmental Benefits of Impact Windows
Impact windows not only save you money but also contribute positively to the environment. By reducing a building’s energy consumption, they indirectly limit the amount of fossil fuel burned in power plants. This action results in fewer greenhouse gas emissions, aiding in the fight against climate change. Even further, UV protection in impact windows helps to prevent fading of furnishings and floorings, increasing their lifespan and reducing the need for replacement, thus decreasing the demand for production of new items and consequently the waste generated. With exceptional durability and long life expectancy, impact windows themselves reduce waste by not needing frequent replacements.
Used thoughtfully, impact windows go beyond their primary function of protection, effectively becoming a part of an energy-efficient and eco-friendly lifestyle.
Comparing Impact Windows to Traditional Windows
Drawing from our previous discussion on the benefits of impact windows, let’s further delve into the comparison between impact windows and traditional ones. This comparison will bring to light elements such as initial costs, long-term savings, durability, and maintenance.
Initial Costs vs. Long-Term Savings
No denying, impact windows tend to have higher initial costs than traditional windows due to their sturdy construction and advanced protective features. That said, the cost difference is balanced out, over time, by long-term energy savings. Think of it as an investment – you spend a bit extra at the beginning but save significantly over time in reduced energy bills. Under extreme weather conditions, these savings are markedly higher as impact windows maintain home temperatures efficiently, lessening the need for heating and cooling systems. Thus, although you might need to spend more upfront on impact windows, the long-term energy savings make them a cost-effective choice.
Durability and Maintenance
In terms of durability, impact windows outshine traditional windows. Made from laminated glass and strong frames, impact windows withstand strong winds, flying debris, and even attempted break-ins, ensuring your home’s structure and interior remain intact. Traditional windows, on the other hand, might shatter or break under similar circumstances, incurring repair or replacement costs.
Looking at maintenance, impact windows also have the upper hand. Their top-tier construction reduces the need for constant upkeep or replacements. Unlike traditional windows, where regular maintenance is part of the package, impact windows typically require a simple wipe-down to keep them clean and clear. This feature not only saves time but also reflects further savings in terms of reduced maintenance costs.
So, taking into account the costs, durability, and maintenance needs, impact windows clearly surpass traditional ones, marking themselves as a preferable, energy-efficient home upgrade.
Impact Windows and Building Codes
