Hunan Haolv Building Materials Co., Ltd. brings 19 years of manufacturing excellence to the production of Arch Top UPVC Windows. Our source factory operates under ISO, CE, and AAMA certifications, delivering architectural-grade solutions for distinctive projects worldwide. These curved-design windows feature precision-fabricated UPVC frames that maintain structural integrity across custom dimensions. With our strategic partnership with CONCH for premium raw materials, we guarantee thermal performance ratings and acoustic insulation of 30–45 dB sound reduction. Our complete system includes tempered or laminated glass options, EPDM sealing technology, and corrosion-resistant hardware—all customizable to your specifications. Delivery takes 25–30 days from order confirmation.

Traditional rectangular windows limit architectural expression. Your projects deserve better.
Our Arch Top UPVC Windows transform ordinary spaces into visual landmarks. The curved profile adds elegance to villas, churches, and high-end residential developments. We fabricate each unit to exact specifications, whether you need semi-circular, elliptical, or pointed arch styles.
The UPVC material resists UV radiation and temperature extremes without warping. This means your windows maintain their graceful curves for over 30 years. Unlike wood that rots or aluminum that corrodes, our frames stay beautiful through harsh weather conditions.

Energy costs drain your budget. Noise pollution disrupts comfort.
Our enhanced profile depth accommodates larger glass units for maximum insulation efficiency. The multi-chamber UPVC structure creates thermal barriers that reduce heating and cooling expenses significantly. You'll notice lower utility bills from the first month of installation.
The strong gasket system seals effectively against external elements. This prevents dust and pollen infiltration, improving indoor air quality for occupants with allergies. During heavy rain or severe storms, the water drainage design prevents accumulation and potential damage.
For properties in busy urban areas, the acoustic insulation delivers exceptional noise reduction. Your clients enjoy peaceful interiors despite external traffic or industrial activity.
Standard windows don't fit non-standard openings. Generic solutions waste time and money.
We support deep OEM/ODM customization based on your architectural drawings. Our engineering team works with you to optimize dimensions, glass specifications, and hardware selections. Whether you need Gothic arches for a heritage restoration or modern curved designs for contemporary builds, we fabricate precisely to requirements.
The one-stop procurement approach simplifies your sourcing. We supply matched frames, cut-to-shape glass, and color-coordinated hardware from a single source. This eliminates compatibility issues and coordination headaches between multiple suppliers.

Maintenance costs accumulate over decades. Material failure disrupts occupants.
Our UPVC formulation doesn't rot, rust, or corrode even in coastal environments with salt exposure. The material maintains structural stability through temperature fluctuations from -40°C to +80°C. High-grade locking mechanisms provide superior security against forced entry attempts.
The weather-resistant properties mean you won't face callbacks for warping, fading, or seal failures. Your reputation stays intact while building owners enjoy decades of trouble-free operation.
Arch Top UPVC Windows suit various high-value applications. Install them in residential villas where homeowners want distinctive curb appeal. Churches and religious buildings benefit from the traditional arch aesthetic combined with modern performance. Landmark commercial properties use custom shapes to reinforce brand identity.
Architects specify our products for projects requiring both visual impact and functional excellence. The combination of custom fabrication capability and proven durability makes us the preferred partner for demanding applications.
Complex projects need more than just products. You need expertise and reliability.
Our mature engineering team provides free technical consultation and solution design. We analyze your specifications and recommend optimal configurations for thermal performance, structural requirements, and budget parameters. Sample support is available with shipping costs covered by you.
Full project follow-up ensures smooth execution from inquiry through delivery. With sufficient inventory and established supply chains, we meet the 25–30 day lead time consistently. This predictability helps you maintain construction schedules without delays.



Q: Can you fabricate pointed or elliptical arches instead of semi-circular?
A: Yes, we manufacture any arch geometry based on your CAD drawings or templates. Provide dimensions and radius specifications for accurate quotation.
Q: What's the maximum span for a single arch unit?
A: Our production capacity handles arches up to 3 meters wide, depending on structural requirements and glazing weight. Contact our engineers for larger spans requiring mullions.
Q: Do the curved frames support triple glazing?
A: Absolutely. Our enhanced profile depth accommodates triple-glazed units for maximum energy efficiency in extreme climates.
Q: How do you ensure the glass fits the curved frame perfectly?
A: We use CNC cutting technology to shape glass precisely to the frame curvature. Each unit undergoes quality inspection before shipment.
Q: What colors are available for the UPVC frames?
A: Standard colors include white, gray, and beige. We offer custom color matching and wood-grain finishes for larger orders through our OEM service.
