1. Good ventilation effect
The casement window sash can be opened to the maximum effect, so that the indoor air can be fully circulated. Ensure indoor ventilation, making the indoor air fresh and comfortable.
2. Security and anti-theft
When the casement window is closed, the four sides are fixed, and the sash handle is operated indoors, and the hidden hinges are used in the production of the casement window at this stage, so the safety of the product is greatly improved.
3. Sealed insulation
The casement window has strong sealing performance and good thermal insulation performance. Multiple locking points around the doors and windows are closed to further ensure the airtightness of the room.
1. I need new windows. What's the first thing I need to know about windows and energy efficiency?
Replacing your windows with energy-efficient windows can help reduce your utility bills, but the benefits go far beyond that. Choosing energy-efficient windows can make your home more comfortable because their performance determines how much heat enters and escapes through the windows.
2. How do I know if my windows or doors are energy efficient?
Certification programs such as the National Fenestration Rating Council (NFRC) and those administered by Energy Star provide ratings designed to indicate a window or door's efficiency. Various performance ratings—such as U-factor and solar heat gain coefficient—measure how effective a product is at insulating and blocking the sun's heat, among other things.

How to maintain it?
powder coated aluminum
Clean aluminum with water and a soft, non-abrasive cloth.
In some cases, adding a mild detergent to the water may help.
Make sure to rinse the surface thoroughly after cleaning to remove all cleaner residue.
Remove excess water.
mild environment
In the countryside, away from the coast and remote industrial and urban activities. Clean aluminum every 6 months.
medium environment
Predominantly urban, inland and away from heavy industrial activity. Clean the aluminum every 3 months.
Tropical/Harsh Environment
Coastal/marine, subject to salt deposits, within 15km of the east coast or 10km of the west coast of Australia. Clean aluminum every 2-4 weeks.
Glass
Clean the glass with water and a soft, non-abrasive cloth. In some cases, glass cleaning fluid may be of some benefit. Always follow the manufacturer's instructions. Do not use harsh chemical cleaners. When using glass cleaning fluid, make sure the surface is rinsed well to remove any residue.
Make sure to remove excess water. Take extra care when cleaning low-e glass. Avoid damaging the coating; doing so will affect the performance of the glass. Clean the glass 3-4 times a year. Shower screen glass needs weekly cleaning to remove soap stains. These stains will slowly corrode the glass, permanently damaging it.
hardware
All hardware requires regular maintenance such as handles, locks, hinges, strikers, door closers, etc.
Clean the exterior surfaces with water and a soft, non-abrasive cloth. A light spray of lubricant (WD40, RP7, or similar) will keep the hardware in good working order. Check the screws on the hinges and fixings to make sure they are not loose.
track
Use a vacuum or brush to remove excess dirt or grit from windows, doors, or closet door tracks.
Make sure the drain holes in the window and door tracks are not blocked. Wipe the track with water and a soft, non-abrasive cloth. Clean the track 3-4 times a year.
Door and window roller
Remove sliding panels from windows or doors. Remove the rollers from the sliding panels. Clean the rollers with water and a soft, non-abrasive cloth. Clean the rollers 3-4 times a year.
