Q. Market Demand And Innovation – How Is The Growing Demand For Sustainable And Acoustically Efficient Buildings Influencing The Development Of Your Façade, Door, Window, And Glazing Solutions?
The demand for sustainable, energy-efficient, and acoustically superior buildings continues to rise. We integrate Low-E double and triple glazing, acoustic PVB interlayers, and multi-chambered thermal-break uPVC and aluminium profiles to enhance building performance, comfort, and sustainability.
To address urban noise pollution, Lingel offers acoustic glazing systems that can reduce sound transmission by 30–60 dB, supported by advanced double-seal gasket technology that ensures airtightness and minimises air leakage. Its energy-efficient solutions, including Low-E glass and thermal-break aluminium systems, help maintain indoor comfort while reducing HVAC energy consumption. Shading devices like roller shutters or venetian blinds further improve insulation against heat.
Sustainability is a key pillar of Lingel’s product strategy. We promote recyclable uPVC materials, we take measures and offset carbon emissions, and source certified German timber while supporting reforestation initiatives. Also, our panoramic windows, skylights, and conservatories maximise natural daylight while controlling glare and heat gain. As urbanisation, green building adoption, and environmental awareness accelerate, demand is shifting toward high-performance façades, larger window walls, automation, and sustainable materials. Backed by global expertise and continuous innovation, Lingel Windows is well-positioned to meet these evolving market needs and shape the future of modern fenestration.
Q. Acoustic Performance Metrics -What Performance Parameters Should Architects And Developers Evaluate When Selecting Windows, Façades, And Glazing Systems For Superior Acoustic Comfort?
Acoustic comfort is a critical consideration in modern buildings, especially in urban environments exposed to traffic, construction, and other external noise sources. When selecting windows, façades, and glazing systems, architects and developers should evaluate key parameters such as Sound Reduction Index (Rw), Sound Transmission Class (STC), glazing configuration, air-tightness, frame design, and overall system performance. While glass is important, effective acoustic insulation depends on the complete fenestration system. Also, it has to be predefined where the building is or what the usage of the building is; office buildings and malls have a completely different demand on the noise and acoustic parameters compared to hotels. Whoever is responsible for the planning has to take this into consideration, because achieving the highest reduction is not always advisable, nor affordable, because reducing only a few decibels can have a significant cost increase as a negative side effect.
The orientation of a building plays a crucial role in determining performance requirements. West- and south-facing façades typically experience higher solar exposure and heat gain, requiring enhanced thermal control and solar protection. In contrast, north- and east- facing façades receive less direct sunlight and may require different performance parameters. Therefore, façade, window, and glazing specifications should be tailored to each building orientation to achieve the optimal balance of comfort, energy efficiency, and cost.
At Lingel, we achieve acoustic performance through Precision-engineered uPVC and aluminium profiles, multi-chamber frame designs, advanced gasket systems, and high-quality hardware that work together to minimise sound transmission and maintain long-term air-tightness. Lingel systems support a variety of glazing options, including laminated, double-glazed, and acoustic glass units, allowing solutions to be tailored to specific project requirements.
By combining robust profiles, premium glazing compatibility, and precise installation standards, Lingel windows create an effective barrier against external noise while maintaining aesthetics, energy efficiency, and durability. The result is enhanced occupant comfort across residential, hospitality, healthcare, and educational spaces.
Q. How Do Your Products Contribute To Achieving Sustainability Targets Such As Energy Efficiency, Occupant Comfort, Green Building Certifications, And Reduced Carbon Footprint?
Our products are tested for durability, and we ensure the lifecycle is maintained. India, where wind loads vary significantly, from moderate inland zones to high-pressure coastal cyclone-prone regions, fenestration systems must be engineered to respond to region-specific demands. ccc are tested in accordance with IS 875 – Part 3, the Indian Standard governing wind loads on buildings. This ensures their suitability across diverse climatic zones, including high-rise applications and coastal environments exposed to extreme wind events.
Performance benchmarks underline this capability. Lingel uPVC window systems are tested up to 3.0 kPa (3000 Pascal), while aluminium systems are tested up to 3.0 kPa (3000 Pascal). Test to failure above 4.5 kPa. These high-performance thresholds ensure minimal deflection, structural stability, and long-term reliability, even under intense wind pressure. Beyond structural integrity, this also safeguards air tightness and water tightness, which are critical parameters in maintaining performance under these conditions.
Q. What Solutions Does Your Company Offer For Upgrading Existing Building Façades And Fenestration Systems, And What Benefits Can Building Owners Expect From Such Retrofits?
After a period of 20 years plus, most homes go into renovation and retrofit windows play a critical role, as timelines matter the most, especially when the homeowners are living there. All our existing customers can upgrade their existing Lingel systems to Lingel Panzer glazing or Lingel Safety Box, so the total combination of glazing and hardware can be upgraded.
