It’s never easy to switch system suppliers. When you’re busy, it’s hard to find the time to pay due diligence and research your options, and when you’re quiet, your focus is on finding new business and playing it safe. It’s also daunting to switch suppliers when so many changes are happening market-wide. But working with the wrong supplier can chip away at your efficiency, productivity and ultimately your reputation.
When you work with the right supplier, it enhances your business. You can benefit from products that are easier and quicker to fabricate and install, quality and sustainable solutions that switch consumers on, and business support and marketing packages that are genuinely helpful.
Here are just a few reasons why Kömmerling installers enjoy working with us.
Industry-leading innovation in windows and doors
Kömmerling has a long history of delivering innovative window and door systems around the globe, but our commitment to continuously invest in technically better products never falters. Fenestration has always been a hugely competitive sector, which makes it even more imperative for suppliers to help their customers stand out from the competition.
Our impressive research and development teams understand the importance of keeping fabricators and installers ahead. They meticulously examine and engineer every aspect of our systems to make them technically better than their alternatives.
An example of one of our industry-leading innovations can be found in our flush sash door system. The system has co-extruded flipper gaskets that seal onto the frame, rather than needing to be rolled in. It has also been designed with thicker side walls to ensure timberweld and mechanical weld prep detail is more robust, and can achieve glazing depths of 28mm, 36mm and 40mm.

Energy-efficient window and door systems
The Energy Saving Trust suggests that around 22% of carbon emissions in the UK come from our homes. Kömmerling’s range of PVC-U, aluminium, and hybrid windows and doors offers significant savings thanks to the company’s ongoing dedication to energy-saving improvements.
Kömmerling’s PVC-U flush sash window, for example can achieve a 1.2w/m2K U-Value with full steel reinforcement and a double-glazed unit. This is better than some of our competitors who remove the steel from the sash or frame, or even mullion to achieve a similar result. We can achieve these impressive U-Values because we utilise a 64mm deep sash profile with six chambers and shape the steel reinforcing to create a pseudo seventh chamber.
Another example of how we can help installers to leapfrog the competition where energy efficiency is concerned is with our Kömmerling 76 system. This profile offers customers the flexibility of double or triple glazing with a double-glazed casement able to achieve a U-Value of 1.2W/m2K and a triple-glazed window able to achieve a U-Value of 0.78 W/m2K.
Sustainable window and door solutions
Consumers are aware and proactive when it comes to recycling, but the Holy Grail businesses should be aiming for is closed-loop recycling. This is where recycled materials are used to make more of the same product. In the window industry, this means recycling old window profiles and grinding them into pellets, which can then be used with high-quality new material to make new windows.
Closed-loop recycling saves energy, reduces CO2 emissions, and cuts waste. Kömmerling was one of the founding members of just such an initiative for the window industry.

Diversify with a supplier you can trust
The home improvement market is unpredictable. We have peaks and troughs that last years but within that we have ups and downs that might only last a week or two. That makes it hard for installers to plan their time, materials and resources. The more products installers have in their armory, the more flexibility they have. There are more opportunities to approach more potential customers, with the possibility of upselling once you have a foot in the door.
Kömmerling has a range of building products as well as aluminium, hybrid and PVC-U window and door systems to support customers looking to diversify. We have a lot of experience in the building products sector, as well as windows and doors, so customers know they can trust us to provide quality solutions across the board. We have recently launched the KömaPan premium exterior cladding solution as well as the KömaDek sustainable decking system.
