In China, there is a significant price gap in the window & door market. Some windows have a comprehensive average price of 2,000 RMB per square meter, while others are 1,000 RMB per square meter on average.As a layperson looking to purchase windows and doors, how to make a choice?

Generally speaking, you get what you pay for. Expensive windows certainly have their reasons for being costly, and cheaper ones also have their reasons for being affordable. I will compare LEAWOD with other products on the market, using charts to show the differences in their costs.

Items	LEAWOD(High-end )	OTHERS(Low-cost)	Analysis
Design Patents & International Awards	(1)Holds over 50 patents; (2)First factory apply seamless welding technology to aluminum doors and window manufacture (3)Inventor of the R7 safety rounded corner design on windows	(1)Is there willingness to invest in R&D?(2)How much is invested annually?	LEAWOD is an enterprise that has consistently focused on R&D for over 20 years.In contrast, many small factories lack R&D capabilities and often directly imitate or copy others’ products. They typically replicate only the appearance without understanding the core design philosophy.
Technologies	(1)Seamlessly Welded Frame & Sash(2)R7 Safety Rounded Corners(3)Cavity Foam Filling(4)Non-return Drainage System	(1)Seamed and Assembled Frame &Sash(2)Sharp Corners caused injury(3)Hollow Cavities(4)Punched-Hole Drainage	All of LEAWOD’s craftsmanship is independently developed and original.The others commonly adopt outdated joining techniques and have not used key technologies such as corner sealing required for system windows, resulting in inherent design flaws in their products. But LEAWOD is more willing to enhance customer experience through increased investment, committed to pursuing superior door and window performance.
Profiles	(1)National Standard Aluminum Alloy 6063-T5/T6; Primary Aluminum(2)Profile Thickness: If labeled as 2mm, the main load-bearing structures of the cavity consistently achieve 2mm, with the thickest sections even exceeding 3mm.	(1)Non-Standard Aluminum; Recycled Aluminum(2)Profile Thickness: If labeled as 2mm, it may only refer to specific parts of the frame, while sash profiles might be as thin as 1.5mm.	When you see a factory’s quote with a high linear weight but a low price, you should be skeptical. After all, no factory is willing to sell products at a loss. This situation typically indicates either the use of non-standard aluminum profiles or a failure to meet the thickness specifications stated in the documentation.
Hardwares	Imported Hardware	Domestic Hardware	The quality of domestic hardware are also improving.However, it depends on whether the manufacturer chooses to work with them. Because domestic hardware is also divided into top-tier brands and smaller factory products, which leads to price differences.
Glasses	(1)Laminated glass from large factories ensures guaranteed thickness(2)Filling with inert gas enhances energy efficiency(3)Quality standards exceed national and industry requirements.	Unclear	It would never happened in LEAWOD:6mm glass, but only 5.5mm. Established factories with strong capabilities pursue long-term development rather than risking their reputation by substituting inferior products.In terms of quality, laminated glass from major factories offers higher flatness and a lower likelihood of spontaneous breakage later on. However, for large-sized glass, spontaneous breakage cannot be 100% avoided . To reduce or avoid the risk of glass breakage, it is recommended to increase the investment for ultra-clear, uniform-quality glass.

After-sale Services	Full Window Warranty for 5 Years	Full Window Warranty for 10 Years even Lifetime Warranty	Do you believe in lifetime warranties?Let me share a personal experience: When I chose a custom wardrobe that promised a lifetime warranty at a low price, I thought the chance of needing repairs was low, so there was no need to choose a big brand. Besides, I could always contact the manufacturer at anytime. Three years later, when a drawer handle came loose and needed fixing,I discovered the manufacturer had already gone out of business. This is the risk that comes with small factories—they boldly make promises that satisfy customers, but they may disappear from the industry just a few years later.You might ask why LEAWOD, which uses only the best raw materials, offers only a 5-year warranty. The reason is simple: we promise only what we can deliver. We want to build a long-term partnership with you.
