Mannlee Windows at a Glance
US homeowners face higher energy bills in 2026 amid volatile prices and stricter efficiency codes. Replacement windows cut costs by $100–$465 yearly per DOE estimates, with payback in 7–15 years. Mannlee fits as a mid-tier manufacturer listed among top replacement window brands for 2026. This China-based company delivers energy-efficient aluminum, vinyl, UPVC, and acrylic glass windows to partners in 48 countries.

Their products hold AAMA, UL, Energy Star, and Miami-Dade certifications, surpassing key US standards.
Mannlee Company Overview
Mannlee operates as a brand of Yankang Building Materials (Foshan) Co., Limited, founded in 1998. The company brings over 26 years of window manufacturing experience from headquarters in Foshan, Guangdong, China. Production spans 18,000 square meters across facilities in Foshan and Zhongshan City, employing over 300 skilled workers. As a five-star manufacturer, Mannlee integrates US and Japanese technology into efficient lines with rigorous quality testing.
They focus on B2B and wholesale, supplying premium custom doors, windows, curtain walls, and partitions worldwide. Over 3,200 product solutions and 1,000+ custom cases serve partners in 48 countries. Compared to US brands like Pella or Andersen, Mannlee offers similar mid-tier quality at lower material costs but relies on importers for US delivery. Common critiques include longer lead times from China and less direct consumer support.
Mannlee Product Lines and Window Types
Mannlee produces aluminum, vinyl, UPVC, and acrylic glass windows. Acrylic glass weighs 50% less than standard glass and recycles 100%. Key offerings include garden windows, jalousie windows, commercial windows, French pane windows, sliding windows, casement windows, and custom aluminum frames.
They cover popular US styles:
- Double-hung: Both sashes tilt in for cleaning; suits any story.
- Single-hung: Budget option with fixed upper sash; common in South.
- Casement: Crank-out for max ventilation and tight seals.
- Awning: Top-hinged for rain-resistant airflow.
- Sliding: Horizontal for wide ranch openings.
- Picture/fixed: Best energy performance, pairs with operators.
- Bay/bow: Projects outward for space and views ($1,500–$5,000+ installed).
Distinctives include hurricane-rated options with 99% UV block, proven in Miami Beach Resort. All carry NFRC labels for U-factor, SHGC, VT, air leakage, and CR. ENERGY STAR Version 7.0 specs apply by zone: Northern U≤0.27, Southern U≤0.40/SHGC≤0.25.
Mannlee Pricing and Value
Mannlee positions in the mid-tier at $300–$700 per window installed for standard double-hung vinyl with Low-E glass and argon fill. Budget lines start at $150–$400; premiums hit $700–$1,500+. These are national averages; add 20–30% for shipping from China.
Breakdown: Materials 40–60%, labor 30–50%, permits/disposal 5–10%. A 2-person crew installs 8–12 standard windows daily; bays take longer.
Value shines in certifications like Energy Star Most Efficient (U≤0.20 possible) and Miami-Dade for coastal homes. Acrylic options cut weight for easier handling. Payback matches industry at 7–15 years via energy savings, plus noise and comfort gains. Critics note potential quality variability in imports, so verify NFRC/AAMA labels. Federal 25C credit covers 30% up to $600/year for Energy Star windows (Form 5695, expires 2032).

Mannlee holds quality certifications from AAMA, SAI Global, UL, FSC, PEFC, LEED, and Energy Star. Products exceed ASTM E1886/E1996 and Miami-Dade hurricane codes.
