Fiberglass windows are one of the most energy-efficient windows available on the market today and with the recent technologies and enhancements, fiberglass now caters to the intricate profiles required for window designs such as bay windows, allowing homeowners more opportunities for customization while enjoying the benefits of this window material

Milgard has also recently engineered window and door products that are resistant to water, cold, heat, insects, salt, and UV radiation resulting in energy-efficient fiberglass windows and doors that look great in any season and climate. Take a closer look at these features to know what to look for when buying high-quality fiberglass windows for your home or building.

Less Reliance on Electricity

Weather damage can lead to gaps and draughts, which send the HVAC system to work harder than it should. Fiberglass frames are robust, durable, and absorb excess moisture, meaning you don't have to worry about the weather driving up your energy bills. If you buy high-quality fiberglass windows, you can expect to save hundreds of dollars annually.

The main reason why windows cannot adequately insulate houses is the lack of weather resistance of their frames. Fiberglass windows are made to withstand extreme heat or cold, and the sturdy, durable frame must be rigid to prevent it from expanding or contracting in weather changes. Most frames made of wooden material tend to absorb excess moisture, which ultimately causes the frame to rot and deform. Fiberglass windows are made of a composite material that offers many advantages over wood, aluminum, and vinyl in the production of energy-efficient windows.  

The reason they are greener and why they put more money in your pocket is because of their strategically placed insulation. These windows behave like wooden windows in terms of the natural insulation value it provides but unlike wooden frames that rot and eventually undermine the insulating power of glass and lead to a loss of insulation, fiberglass window frames retain their insulating value over time. Aluminum window frames conduct heat and cold inside a building, but fiberglass does not. 

Fiberglass windows and frames have insulation that fills the air spaces to give them better insulation than aluminum or vinyl windows. Fiberglass has a naturally lower thermal conductivity without thermal breaks compared to other materials and it is 500 times less conductive than aluminum. This means that large, fiberglass windows transport less hear or cold and are less susceptible to corrosion and wear than aluminum and vinyl windows. Vinyl also weakens over time, which leads to a loss of insulation performance.

fiberglass windows benefits for your home

When you stop and think about it, the best thing about all the savings on heating and cooling costs from installing fiberglass windows makes it worth it. A single-pane window cannot absorb all the heating and cooling effort because the glass is too thin, and most homeowners believe that most of the energy wasted in windows is due to draughts and cracks. That is why it is so important to choose the right window frame for your home, not only for design and durability but also for its energy-efficiency capabilities. 

Less Energy and Resources Required For Manufacturing

The manufacturing technology for fiberglass windows was developed only 40 years ago and now this innovation is growing in popularity in the US market due to its benefits. 

Pultrusion is a process that is used to prepare fiberglass. During this process, a fiberglass mat is first bathed in resin, before being covered with a glass fiber shell veil, and lowered into a heated die. This helps to harden the resin and makes the fiberglass even stronger. 

Due to its composition, fiberglass is known for the low total energy required to produce the product from the raw material stage to the supply of the fiberglass product.  It does not require additional materials to reinforce it, which means less weight for windows and doors and reduced transportation costs. Because fiberglass is so rigid and stable, it is ideal for windows that contain multiple layers of glass. In fact, the total energy required to make a product from start to finish is called "embodied energy," and fiberglass has a high embodied energy.

Most energy-efficient windows consist of three or even four panes, and have an air space of less than a half to a quarter, however, more space between the panes promotes condensation, which reduces insulation performance.  Depending on your budget, consider replacing large windows with double glazed window panes framed with fiberglass. The type of glass you install in your windows has a great impact on the sunlight and the UV rays that fall through them, which can be a big advantage if you live in San Diego. The construction of the window frame material is important to keep the temperatures in your home low. Wood, aluminum, and vinyl are the most common materials for energy-efficient windows but they lack the stability and rigidity of fiberglass.

Fiberglass windows are a natural choice in the search for an energy-efficient, green and sustainable solution. The main component of fiberglass is glass and it is a highly sustainable solution, as glass is made from resource-saving materials. Glass fibers can expand and contract, increasing the durability of the glazing. It must also have high thermal conductivity, similar to that of steel and aluminum, but with a much lower energy balance. 

For the average American household, energy is wasted in heating, cooling, air conditioning, and other energy-intensive activities. Because glass is an insulator, fiberglass offers the same advantages. Fiberglass windows absorb heat and help you maintain high temperatures in summer and maintain the comfort of your home in winter. Incorporating double and triple glass panes with your fiberglass windows increases the energy efficiency and energy savings of your home.

Easy Disposability

Fiberglass windows and doors are in great demand as a sustainable resource and many fiberglass products have received an ENERGY star label, representing the highest level of energy efficiency and environmental compatibility available on the market today. This means that less waste ends up in landfills because fiberglass products have an extremely long life cycle. They have been developed, tested, and built over decades, so they have a longer life expectancy than other materials. This is important because windows are not easy to replace, so the best option is fiberglass if you want a window frame that is made of high-quality materials that can last for years on end.

Fiberglass frames can last up to 50 years or more  without maintenance, wooden frames can last 15-20 years, and so this is an obvious choice for long-term sustainability. Fiberglass windows provide a great opportunity to build durable residential and commercial buildings to improve the energy efficiency of your building and the sustainability of the building itself. With its natural strength and durability, fiberglass is a good choice for those looking for a high-quality, cost-effective, and environmentally friendly alternative to steel and aluminum. Fiberglass is 8 times stronger than vinyl, and it does not stretch like wood or shrink like aluminum. It is also environmentally friendly, as it emits less carbon dioxide and less greenhouse gas per square meter than conventional glass.

Choosing the Best Fiberglass Replacement Windows for Your Home

If you are looking for more energy-efficient and environmentally friendly fiberglass windows in San Diego for your home, it may be difficult to find a better option than fiberglass windows. Longevity is one of the most important factors for the energy efficiency of a fiberglass window. Fiberglass is also one of the most durable materials available for window use. It keeps its shape and does deflect over time.

These windows are not only energy-efficient but they also look beautiful and they can withstand the strongest storms. Because fiberglass has a much stronger and more robust structure than steel, combined with its inherent longevity, its window frames take less stress on the glass, which means fewer defective gaskets and air gaps. This stability and strength allow fiberglass window frames to withstand high winds, resulting in a more robust, durable, and energy-efficient window frame option. They can withstand temperatures up to 350°F or more and do not become brittle and soft. They are resistant to rot, insect infestation, and corrosion, so simplifying the frame construction and using a high-strength, cost-effective material ensures that the end product can be maintained for a long period of time.

Choosing the best replacement windows for your home and lowering the overall cost of replacing windows can be a daunting process.
