Why use 5+9A+5mm double glazing unit Doors?
The 20mm DGUs doors refer to a type of insulated glass unit (IGU) that is commonly used in both residential and commercial settings. These numbers represent the thickness of each component in the unit: 5mm for the thickness of each glass panel, and 9A refers to the 9mm air or gas-filled spacer between the two glass panels.
Here are some reasons why these double glazing unit doors are beneficial:
Energy Efficiency
Double glazing significantly reduces the amount of heat that escapes from your home in the winter and keeps out the heat during the summer. This can help lower your energy bills.
Noise Reduction
The double-glazing unit also acts as a sound barrier, reducing noise pollution from outside. This is particularly useful in busy urban areas or if you live near a busy road.
Security
The 5mm thickness of the glass panes (the ‘5+5‘ in the specification) makes these doors tougher and more resistant to break-ins compared to single-glazed doors.
Durability
These doors are built to last. The double-glazed units are highly durable and resistant to adverse weather conditions, which means they require less maintenance.
Condensation Reduction
Double-glazing significantly reduces condensation build-up on the interior of the door, helping to prevent issues such as dampness and mold.
UV Protection
Double-glazed doors can block most of the harmful UV rays, protecting your furniture and carpets from fading.
Remember, while DGUs doors may be more expensive upfront than single-glazed options, the long-term energy savings and benefits often make them a cost-effective choice.

- Warp and deformation checking to make sure the glass surface is super flat.
- Strong impact test to guarantee tempered glass, laminated glass, and insulated glass safe for architectural usage.
- Fleshlight to inspect whether have defects during the double-glazed unit glass production
Package Information
- We use plywood crates only Because which made by compressing and bonding processed wood, and can be exported without any complex procedures, making it very convenient.
- The size of the DGUs doors glass is often not uniform. For safety transportation, the interior of the plywood box is filled with pads and blocks to provide corks between the insulated glass. Then, it is wrapped with plywood strips because the more exposed it is, the safer it is. Diagonal bracing of the plywood strips is essential to enhance the strength of the box.
- Many clients ask why we don’t use fully sealed packaging. That’s due to the more exposed it is, the safer it is. During transportation by forklift or crane, it is immediately clear that there are fragile products inside, prompting extra attention to safety.
