In the U.S. construction market, choosing the right window material is not only a design decision—it directly affects long-term building performance, energy efficiency, durability, and cost. Among today’s most popular window materials, PVC (uPVC) windows and aluminum windows are the top choices for both residential and commercial projects. Contractors, builders, and developers often compare these two materials when selecting windows for modern homes, apartments, hotels, schools, offices, and retail buildings. So, which material is better? The answer depends on the project needs, budget, and climate conditions. ✅ Material Overview PVC (uPVC) Windows PVC windows are made from unplasticized polyvinyl chloride, a rigid and thermally efficient material widely used in residential construction in Europe and North America. PVC is popular due to its excellent insulation performance, low maintenance, and cost-effectiveness. It does not rot, corrode, or warp, making it a reliable option for long-term use. Aluminum Windows Aluminum windows are made from extruded aluminum alloy frames, often combined with a thermal break system to improve insulation. Aluminum is known for strength, slim profiles, and modern aesthetics. It is widely used in commercial buildings, high-rise projects, and luxury residential properties where structural performance and large glass areas are required.

Choosing windows and doors with NFRC certification is one of the most effective ways to achieve lasting energy savings and superior comfort in residential or commercial projects. The National Fenestration Rating Council (NFRC) provides an independent, third-party verification of key performance metrics—U-factor, Solar Heat Gain Coefficient, Visible Transmittance, Air Leakage, and Condensation Resistance. These ratings give architects, builders, and homeowners clear, reliable data to compare products and ensure they meet stringent energy-efficiency goals. NFRC-certified products are engineered to reduce heat loss in winter and minimize solar gain in summer, directly lowering heating and cooling costs while improving indoor comfort. Their documented performance supports compliance with international building codes, ENERGY STAR® standards, and green-building programs such as LEED, making them a smart investment for sustainable construction.

Folding doors, or bi-fold doors, are an elegant and practical solution for opening up spaces and creating a seamless flow between indoors and outdoors. They consist of multiple panels that fold neatly to one side along smooth tracks, offering wide, unobstructed openings and a modern aesthetic. Operating them is simple—just slide and fold the panels gently while ensuring hinges and rollers move freely. Proper installation is key: frames must be level, tracks firmly fixed, and panels correctly aligned to prevent sticking or warping over time. Regular maintenance, such as cleaning tracks, lubricating hinges, and checking for loose screws, ensures longevity and smooth operation. Available in aluminum, UPVC, or timber, folding doors come in a variety of finishes, colors, and glass types, from clear to tinted or frosted, allowing homeowners and designers to create spaces that are stylish, bright, and inviting. Perfect for patios, living rooms, or commercial spaces, folding doors combine functionality with eye-catching elegance.

For projects that demand unobstructed views and refined elegance, KDSBuilding’s tempered glass balustrades deliver a perfect solution. Ideal for balconies, staircases, rooftops, decks, and pool enclosures, our systems combine safety, modern design, and light-maximizing clarity. Crafted with tempered or laminated safety glass, ranging from 8mm to 21.5mm in thickness, our balustrade systems are built to meet or exceed international impact and load standards.
