The Challenge

Executing three individual villas for three family members with more than 300 windows in total within the same plot, following the individual design, taste and aesthetics, and maintaining the overall look of all three villas as one structure, was a challenge. It was also a challenge to unite the different aesthetic expectation of the owners so that the overall concept of the building remained the same. Multiple sample approval lead to the slow execution of the project, but it was completed as per the time frame calculated and given by the owner.

The Task

The task included collaboration and development with Lingel R&D team at the headquarter in Germany, on site planning with the steel contractor, etc. Lingel had taken the entire responsibility of fabrication of each window as per actual size due to on site fabrication tolerances of the steel sub frames.

Unique Aspects of the Project

The project required the installation of more than 300 individual doors and windows with over 500 glasses in total, with inbuilt security grill as per colour chosen by the customer. Special handle colour and design were developed for this project. Special McCoy chain meshes were used for windows. Customised internal doors as uPVC doors confirming each height individually as per actual site measurement were provided, ensuring uniformity. With an overall execution time of more than two and a half years to handover, each window as an individual masterpiece to the customer was the main challenge.

Thermal transmission All windows are double glazes with Ug 2.8w/Sq mK, Frame 1.8w/Sq mK
Acoustic values Double-glazed windows providing Rw of glass of 32 dB
Air permeability Not tested and no specific requirement. But all casement and fixed glazing with double gasket sealing are considered and tested air tight

Maintaining Quality, Execution and Time Line

All the products were fabricated as per actual size. Lingel had the responsibility of correct measurement. The site team coordinated with the civil contractor, relevant agencies, as well as the architects and provided the final action plan to the customer/project management.
