Our windows feature multi-point locking, EPDM weather seals and easy-care white or laminated color finishes that never rust, warp or require painting. Fully customizable in size, color and glazing. NFRC certified, OEM/ODM supported. Contact us for a quotation, or send your drawings for a custom quote.

Key Features

1. Multi-Chamber UPVC Profiles — hollow multi-chamber construction provides natural thermal insulation, keeping rooms warm in winter and cool in summer.

2. Welded Frame Construction — four-corner heat welding creates seamless, watertight joints for long-term airtightness.

3. Excellent Energy Efficiency — multi-chamber UPVC with optional Low-E or triple glazing achieves a U-Factor as low as 1.0 W/(m²·K).

4. Low Maintenance — UPVC never rusts, rots or fades; no painting or regular upkeep required.

5. Galvanized Steel Reinforcement — steel inserts inside the profiles provide rigidity and wind load resistance.

6. Multi-Point Locking Security — multi-point locks with hardened steel locking points resist prying.

7. Multi-Seal Weather Protection — EPDM gaskets deliver Class 8 air permeability and Class 6 water tightness.

8. Full Customization — size, color (white, wood-grain laminate, co-extruded colors) and glazing fully customizable; OEM/ODM supported.

FAQ

Q1: What is the difference between vinyl (UPVC) and aluminum windows?

A: UPVC windows offer natural insulation with multi-chamber profiles, lower cost and zero maintenance (no rust, no painting), while aluminum windows provide higher structural strength and more color options.

Q2: Do vinyl windows fade or yellow over time?

A: Our UPVC profiles are UV-stabilized with a co-extruded weather layer. With normal care, white frames keep their appearance for decades; wood-grain foil and color options are also available.

Q3: How long do vinyl windows last?

A: UPVC frames are typically rated for 30+ years of service life with minimal maintenance.

Q4: What is the minimum order quantity (MOQ)?

A: custom MOQ depends on configuration — confirm with our sales team.

Q5: What is the production lead time?

A: Around 15–25 days for standard windows and 25–35 days for custom orders; partial shipments can be arranged for large orders.

Q6: What is the maximum opening sash size?

A: Casement sashes are generally produced up to about 1200mm wide × 1800mm high; steel reinforcement can be upgraded for larger sizes and high wind load areas.
