Window Replacements & Installations

Whether for new construction or existing homes/businesses, windows are an important aspect. Older windows are often responsible for over 25% of heating/cooling costs. With advancements in technology, new windows are a cost-effective and rewarding choice. Stellar Energy Contractors encourages you to consider Smart Windows. Low-emissivity glass keeps the indoor environment cooler in the summer by reflecting the sun back and also reflects infrared radiation within the space to keep it warmer in the winter. By blocking UV rays, these innovative windows further protect against damage to home furnishings. There’s even a special coating that combines with sunlight to prevent organic compounds from sticking to the glass while allowing water to rinse the dirt away for self-cleaning.
