The Simplicity Internal Door offers three tailored specifications to fit different wall profiles, providing a clean aesthetic with reliable sealing and versatile performance for any interior space.
Description
Simplicity Internal Door: Three Tailored Specifications for Distinct Architectural Profiles.
Series 4065 Specification
Our Simplicity Internal Door, in its Series 4065 configuration, balances refined performance with material efficiency. Its profile wall thickness is 1.4mm. Furthermore, the glass sash measures 65mm wide and 40mm thick. For glazing, it uses a 4mm+20A+4mm insulating glass unit. Additionally, a triple EPDM composite seal ensures effective sealing. The structural core utilizes 6060-T66 aluminum alloy profiles. Finally, this design requires a minimum wall thickness of 75mm for proper installation.
Series 3550 Specification
The Series 3550 simplicity internal door offers a streamlined design for different project needs. It features a profile wall thickness of 1.2mm. Moreover, its glass sash is 50mm wide and 35mm thick. The glazing is a slightly narrower 4mm+15A+4mm insulating glass unit. This version also employs a triple EPDM composite seal and is constructed with 6060-T66 aluminum alloy profiles. Consequently, it is compatible with a reduced minimum wall thickness of 55mm.
Series 4012 Specification
For projects requiring enhanced strength, the Series 4012 simplicity internal door presents a robust alternative. Its profile wall thickness increases to a solid 2.0mm. The glass sash measures 12mm wide and 40mm thick. This version utilizes a simple 8mm single glass panel. Like the other series, it is sealed with a triple EPDM composite seal and built from durable 6060-T66 aluminum alloy profiles. Ultimately, it is designed for a minimum wall thickness of 60mm.
Simplicity Internal Door: Common Features & Design Philosophy
Despite their different specifications, all series share key quality hallmarks. Each door uses 6060-T66 aluminum alloy profiles as a foundation for stability. They all integrate a reliable triple EPDM composite seal for consistent performance. This shared technical basis allows for clear design choices: Series 4065 offers balanced insulation, Series 3550 maximizes space efficiency, and Series 4012 prioritizes structural robustness.
Summary of Application
In summary, the Simplicity Internal Door provides three distinct specification paths within a unified design language. Therefore, you can select the exact balance of profile strength, glazing performance, and spatial requirements that your specific interior application demands, ensuring both aesthetic simplicity and technical precision.
