uPVC windows

At Rhea Windows, we specialize in high-performance uPVC windows engineered for superior thermal insulation, durability, and aesthetic versatility. Whether replacing old windows or building new, our European-engineered systems deliver measurable savings and long-lasting performance.

Why Choose Rhea’s uPVC Windows?

Energy Efficiency That Saves Money Our uPVC systems achieve thermal transmittance as low as Uw = 0.76 W/(m²K), meeting passive house standards. This means 20-30% lower heating and cooling costs compared to older windows—many homeowners recoup their investment within 5-7 years.

Superior Durability & Low Maintenance uPVC resists corrosion, rot, and weathering without painting or staining. Simply wash with mild soap and water. Our systems maintain integrity for 30+ years with minimal upkeep.

Exceptional Sound Insulation Reduce outside noise by up to 48 dB, creating peaceful indoor environments—ideal for Connecticut coastal homes and urban locations.

Advanced Security Multi-point locking mechanisms and RC2 burglar resistance protect your family and valuables.
