There are many different window and door profiles on the market for window and door companies to choose from for their customers, but few can compare to Liniar. Made of high-quality materials and designed for superior performance, Liniar will impress your customer base. This blog post will look at what makes the Liniar profile system so unique.

Energy efficiency

The Liniar profile is highly energy efficient, thanks to the multi-chamber construction. This structure helps to keep heat in during the winter and out during the summer, making your home more comfortable all year round while also helping to reduce energy usage. Liniar systems can achieve a WER of A+ and a U-value of 1.2 W/m²K.
