Kommerling: Ensuring Consistent Performance From Factory To Site

Amir Hashmi, Chief Sales & Marketing Officer, profine India, elaborates on Kommerling’s expertise in meeting the growing demand for advanced, high-performance fenestration systems that combine aesthetic efficiency and sustainability, along with ease of installation, by taking an integrated approach that ensures consistent performance of their products from factory to site.

What influence are modern buildings and advanced construction methodologies (like modular/prefab) having on fenestration systems in India?

Modern buildings and advanced construction methodologies such as modular and prefab construction are influencing the evolution of fenestration system significantly in India. With modular and prefabricated construction, many building elements including windows and façade panels are manufactured offsite and then assembled and installed on site as ready to fit units. This has impacted the fenestration industry in various ways such as:

• Standardized window sizes and modular façade panels
• Pre-installed windows in wall panels
• Dry installation methods instead of wet masonry installation
• Faster building construction timelines

Additionally, as contemporary architecture moves towards high-rise developments, a shift towards high-performance and energy-efficient fenestration is evident. At greater building heights, windows and doors must withstand higher wind loads while maintaining structural stability. And at the same time energy-efficient building envelopes have become necessary, increasing the demand for windows and doors with double and triple glazing, Low-E coating, superior thermal insulation, and maximum daylight penetration.

At Koemmerling, we ensure that the performance of our systems is fundamental to their design; hence, our focus is on delivering long-term value rather than short-term cost competitiveness.

Regulatory frameworks such as the Energy Conservation Building Code (ECBC) are also encouraging developers to adopt more efficient glazing windows and façade systems.

Another visible trend is the growing use of curtain walls and large glass facades in urban commercial buildings. And the impact of this on fenestration system can be seen in terms of larger glazing panels replacing the traditional punched windows and structural glazing with minimal framing. These shifts are collectively driving the demand for advanced, high-performance fenestration systems that combine aesthetic efficiency, and ease of installation.

High rises are exposed to external forces like wind loads, thermal expansion, and pressure differentials. So how does Koemmerling ensure installing its window systems in high rises to withstand such extreme environmental forces?

Fenestration in high-rise projects require technical validation beyond aesthetics. At Koemmerling, we engineer uPVC windows & door systems with structural reinforcements, multi-chambered profiles, and advanced sealing technologies to withstand high wind loads and harsh weather conditions.

Koemmerling uPVC window & door systems are tested for air permeability, water tightness and high wind load, as per global standards. Additionally, project-specific wind load calculations are conducted to recommend the correct profile combinations, reinforcements, and glazing thickness. Installation is equally critical; hence we work closely with our authorized fabricators and project consultants to ensure that execution on-site matches the engineered design performance.

With the Indian consumer becoming more quality conscious over price, how is Koemmerling meeting their expectations for high performance window systems that provide both protection from the elements, thermal and sound insulation, and safety against potential break-ins?

Today’s customers are no longer evaluating windows and doors as a commodity — they see them as an investment in comfort and safety. Koemmerling systems deliver:

• Thermal insulation through multi-chambered profile designs
• Sound insulation which is especially crucial in urban environments
• Enhanced security with multi-point locking systems
• Weather resistance against extreme climatic conditions

Backed by German engineering, we ensure that performance is fundamental to the system design. Our focus is offering long-term value rather than short-term cost competitiveness.

How does the company ensure timely supply and consistent quality products to projects where Koemmerling fenestration systems are being installed?

As consistency and reliability are critical in project execution, Koemmerling uPVC window & door profiles are manufactured with advanced extrusion technology and strict quality control protocols, ensuring uniformity in every profile produced. Further we have an extensive network of channel partners and distributors across the nation. Our authorized and well trained channel partners enable streamlined production planning and timely project deliveries.

We emphasize:

• Forecast-based production planning
• Standardized fabrication processes
• Continuous quality audits
• Routine training to fabricators
• Technical supervision for large projects

This integrated approach ensures that performance is consistent from factory to site.

What are the winning points of Koemmerling window systems over other competing brands with equally strong fundamentals?

While several brands operate in this segment, Koemmerling stands apart due to factors such as:

• German brand legacy of over 125 years
• Pioneers of uPVC profiles and worldwide presence
• Lead-free, environmentally responsible formulations
• Advanced multi-chamber profile design
• Proven durability and color stability
• Strong technical advisory support for architects and developers.

We do not compete purely on price — we compete on performance, credibility, sustainability, and long-term value.

What has been the response to Koemmerling’s KömaBoard paneling materials and KömaDoor solutions in India? What can we expect from this vertical going forward?

The response to KömaBoard polymer composite sheets and KömaDoor solutions has been extremely encouraging, confirming that India is steadily moving toward engineered, sustainable alternatives to traditional paneling materials.

With KömaBoard, we are addressing a critical gap in the interior infrastructure segment. Conventional wood-based panels often struggle with moisture, termite infestation, and dimensional instability — especially in India’s diverse climatic zones. KömaBoard offers a technically superior alternative that is water-resistant, termite-proof, recyclable, and highly workable for modular interiors.

Similarly, KömaDoor provides long-term structural strength and aesthetic flexibility. As a holistic door solution, it offers door frames, solid door panels, and architraves. Built with polymer composite material, they eliminate the recurring maintenance cost associated with conventional wooden doors due to termites / borers attack, moisture and water exposure, and extreme weather conditions.

Going forward, this vertical is a strategic growth driver for Koemmerling. As construction becomes more organized and sustainability-driven, demand for factory-engineered, standardized interior solutions will accelerate. Our objective is not just to introduce alternatives, but to redefine how the market evaluates performance, lifecycle value, and environmental responsibility in interior building materials.

What are the company’s initiatives towards environmental responsibility and sustainability?

As sustainability is taking centerstage in future-ready architecture and fenestration, Koemmerling stands as a trusted partner in creating eco-friendly and energy-efficient spaces. Our energy efficient uPVC windows & doors are designed with superior insulation that helps in reducing the load on artificial heating and cooling devices, directly lowering energy consumption.

With a rich heritage, unmatched quality, and a forward-thinking approach to design and sustainability, Koemmerling uPVC window & door profiles have raised the benchmark in the window and door industry. By eliminating lead from its formulation early on, Koemmerling has set an example for responsible manufacturing – placing the occupants’ health and environmental impact at the center of its product developments. Our manufacturing processes also focus on minimizing waste and optimizing resource efficiency. We strongly believe that fenestration is no longer just an architectural element — it is also a sustainability enabler.
