Inles d.d.

Our company has more than 65 years of tradition in producing wooden windows. As a renewable, natural material, wood has specific characteristics that require a great deal of care and knowledge during treatment. Thanks to our know-how, our wood products are among the most highly valued at home and abroad. Profile processing takes place on a new, state-of-the-art production line built in 2012 that together with triple surface treatment using robotic electrostatic application of the top coating ensures products of the highest quality, durability and sophistication.

The latest additions to our selection are products from thermally modified spruce wood (thermal modification is carried out by Silvaprodukt d.o.o.) that feature higher resistance to fungi and insects, less cracking and moisture absorption, all of which contribute to a longer lifetime of your product.

INLES’ roots date back far into the past. Since the 14th century the area of Ribnica has been renowned for the manufacturing of various wooden tools, containers, and other products - the so-called "dry stuff". In 1492, Emperor Frederick III awarded a special patent to the town of Ribnica allowing the sale of wooden products throughout the Empire.

Wood processing is traditionally rooted in the area of Ribnica.

In 1934

the then landowner Anton Rudež of Ribnica built a sawmill under the name Ing. Anton & Marko Rudež, Wood Industry and Trade of Ribnica na Dolenjskem. 

This sawmill is one of the predecessors of today's INLES.

In 1948

the Woodworking Industrial Company of Ribnica was founded, which produces different crates (and box sections).
This year is considered the beginning of the establishment of the company INLES.
