WHY CHOOSE FIBERGLASS?
Windows and doors are an investment in the beauty and function of your residential or commercial structure.
As with any other investment, it is wise to consider the long-term benefits when choosing the best material for your new construction or replacement window needs.
Many builders and homeowners choose fiberglass due to the strength and durability, versatility, and energy efficiency. Fiberglass products from EnerLux offer industry-leading performance, superior energy efficiency, and timeless beauty.
A few things to know about fiberglass windows and doors:
- Fiberglass has thermal conductivity 500 times less than aluminum, minimizing the transfer of heat or cold
- Resists expansion or contraction from changing weather conditions
- High strength to weight ratio
- Naturally resistant to destructive pests like termites and other bugs
- Fiberglass is low maintenance: resists corrosion, pitting, and denting, will not need to be sanded, painted, or stained- delivering significant long-term cost savings over the life of your windows and doors
- More eco-friendly- biodegradable, recyclable, and crafted from abundant and sustainable materials
