Tilt and turn windows are a versatile European window style known for their dual-functionality, offering both a tilting and a turning (swinging inward) operation. The tilt function provides secure ventilation by opening slightly at the top, while the turn function allows for a full inward swing, similar to a casement window, for easy cleaning and maximum airflow.
When energy efficiency, durability, and comfort matter most - Minglei 76 Tilt Turn Windows serve as a great choice for superior insulation, reduced energy costs, and a quieter, more comfortable home in any climate.

For years, Aluminum windows have been specified by architects and builders for their overall strength and lasting value. Because of their rigidity, durability and narrow frames, aluminum windows can be configured into a wide variety of combinations that maximize views. Aluminum windows also are popular because of their low maintenance. They won't rust or rot. You don't have to paint them. And they're available with tough anodized or baked-on finishes.

Minglei is a professional manufacturer of high quality windows and doors with 10+ years exporting experience with two state-of-the-art manufacturing bases with 300,000 m²/year production capacity. We have enjoyed a lot of five-star reviews & recommendations by global customers from more than 60 countries, 80% of whom are from the USA, Canada, Europe, and Australia.



So far, We have certifications and test reports of Canada Energy Star, NFRC, NAMI, AAMA, AS2047 and CE etc.
Energy-efficient, exceptional quality, beautiful design, budget-friendly, those are all about our missions for windows and doors. With advanced & exquisite manufacturing technique, and abundant product application & service experience, Minglei team will fulfill Your needs and meet Your highest expectations.
With "ultimate thermal insulation and energy saving" as its core R&D direction, Minglei Windows and Doors achieves an industry-leading U-value (the lowest U-value among similar products on the platform). Utilizing low-emissivity triple-glazed windows, warm edge spacers, argon gas filling, and a full-window thermal bridge blocking design, it maximizes the reduction of heat transfer between indoors and outdoors. Its winter heat retention and summer insulation effects far surpass conventional products, helping buildings reduce energy consumption by 30%-50%. This aligns with North American Energy Star energy conservation initiatives and saves users long-term energy costs, making it a preferred choice for green buildings.
We use high-grade raw materials, modern technology, cutting-edge manufacturing processes, and skilled workers to produce windows & doors that offer superior longevity, exceptional performance, and unmatched beauty.
Our windows and doors are manufactured flexibly for custom sizes, architectural shapes, colors and specialty finishes. Built to pass your local inspectors' verification under Canada & USA building codes, they are certified by Canada Energy Star, USA NFRC & NAMI to ensure they are energy efficient, safe and sturdy.




We look forward to long-term partnerships where our service and expertise in window and door systems save partners time and money. Having served the North American market for a decade, Minglei delivers professional planning and functional design at ideal prices for custom demands.
We offer no-cost design development and contract documentation with CAD & BIM drawings (elevations, details, installation design). We assist in accurate budget control by evaluating overall schematics—such as recommending cost-effective options in low-visibility or low-sunlight areas to help lower costs without compromising structural integrity.
We hold several international patents to reduce labor costs, such as our unique flanges and assembly-type tubular design. All our products are equipped with nail fin structures for quick and easy installation. Because installation labor can equal or exceed the product cost itself, our patented designs significantly boost efficiency and offer substantial on-site savings.
Our sufficient production capacity assures a 35-day delivery time upon drawing approval. Each window is individually packed with four layers before being placed into strong wooden crates. Weekly shipments to the USA guarantee products arrive in prime condition.
