What is the difference between a replacement window and a new construction window?
New construction windows have a nailing fin designed to be installed directly onto the framing before the exterior siding is applied. Replacement (or retrofit) windows are custom-sized to slide perfectly into the existing window frame or rough opening without damaging the surrounding wall, often using a block frame or a Z-bar (flush fin) design.
Do you manufacture UPVC (vinyl) replacement windows?
Yes. UPVC is one of the most popular materials for residential replacements due to its excellent thermal performance, affordability, and low maintenance. We offer a full line of vinyl double-hung, sliding, and casement replacement windows.
Can you make windows to exact millimeter dimensions?
Absolutely. We specialize in custom manufacturing. Because older openings are rarely standard sizes, you simply provide the exact width and height of the existing opening, and we will manufacture the replacement unit to fit precisely.
What is a Z-bar or flush fin frame?
A Z-bar (or flush fin) is a specific type of replacement frame widely used in regions with stucco or masonry exteriors (like the US West Coast). The fin rests against the outside of the existing aluminum frame, completely covering it and sealing the opening without the need to cut into the exterior wall.
What is your Minimum Order Quantity (MOQ) for contractors?
While we are a bulk manufacturer, we support remodeling contractors by offering flexible MOQs for project-based orders. The most cost-effective shipping method is typically a mixed 20ft or 40ft container, which can hold all the windows and patio doors needed for a medium-to-large residential or multi-family project.
Can I mix different window styles and materials in one container?
Yes. We highly encourage wholesalers and contractors to consolidate their orders. You can mix aluminum commercial windows, UPVC residential replacements, and steel entry doors in a single container to maximize your freight efficiency.
How do you ensure the glass won't break during international shipping?
We have years of export experience. Replacement windows are individually wrapped, protected with shock-absorbing foam corners, and packed tightly into reinforced wooden crates or steel pallets that prevent shifting inside the shipping container.
Do your replacement windows meet local energy codes?
Yes. We offer energy-efficient upgrades such as double or triple Low-E glass, argon gas fills, and warm-edge spacers. Our technical team will help configure the U-value and Solar Heat Gain Coefficient (SHGC) to ensure the units meet your local energy rebate or building code requirements.
What is the lead time for custom replacement orders?
Because every unit is custom-sized, production typically takes 4 to 6 weeks from the time you approve the shop drawings and provide the deposit, plus ocean transit time. We recommend factoring this into your project schedule.
How does ordering direct from China benefit my contracting business?
By eliminating local distributors and middlemen, you significantly reduce your material costs. This allows you to either win more bids by offering competitive pricing to homeowners, or substantially increase your profit margins on every remodeling job.
