Plan glazing areas and opening styles to bring daylight indoors and support fresh-air circulation, with configurations suited to your room layout and everyday use.
Select frame systems, glazing and seals according to your climate and surroundings to help limit heat transfer and reduce unwanted outdoor noise.
Coordinate locking hardware, suitable glazing and frame configurations with your security needs, while choosing proportions and finishes that complement your architecture.

FAQ
Common questions about Doors and Windows manufacturer for project buyers, contractors and distributors.
Q1. What material is the Kojoon door window made of?
A: Kojoon specialize in high-end 6063-T5 bridge-cut aluminum alloy doors and windows, equipped with standard PA66 nylon insulation strips and double-layer tempered glass. We support customization of profile wall thickness and surface craftsmanship, with a choice of domestic or imported hardware brands. All products are accompanied by multiple authoritative certifications such as CE, AS2047, and NFRC.
Q2. How effective is the energy-saving insulation?
A: The aluminum alloy profile effectively blocks thermal bridges, and the insulating glass comes standard with sound insulation. In severe cold regions, it can be upgraded to triple-layer insulating glass + Low-E glass to reduce the U-value. For projects facing the street, laminated insulating glass can be chosen, providing sound insulation up to 45dB, fully meeting the stringent energy conservation and residential standards in various regions.
Q3. What is the standard delivery lead time?
A: The standard delivery time for regular doors and windows is 30 days; for orders involving special-shaped windows, special glass, imported hardware, and those requiring separate certification, the delivery time will be extended accordingly. Before placing an order, we will provide an accurate delivery schedule, ensuring full control throughout the process and eliminating any concerns about progress.
Q4. Can coastal cities rust?
A: Coastal orders are uniformly equipped with a full set of 316 stainless steel anti-corrosion hardware. The aluminum material adopts fluorocarbon spraying technology, which has excellent resistance to high salt spray corrosion. Authoritative salt spray test reports can be provided, significantly reducing the risk of rust and after-sales service from the source, ensuring the product is durable.
