In collaboration with Deceuninck, an article was made for Dom na kvadrat where we presented our company and new production facility.
PVC joinery is easy to maintain and energy efficient, and technological advances in production have also affected the aesthetic component. We found out at Roplast why joinery now looks even better.
Carpentry greatly affects energy efficiency, so it is extremely important to choose a quality product.
“Roplast is a renowned Croatian company that manufactures and installs aluminum and PVC joinery. We have been present on the market for 30 years, which is actually the result of constant improvement and adaptation to the latest technical achievements.
We have thousands of satisfied clients behind us who testify to our dedicated work and the trust we have built over the years,” emphasizes Stefani Runko, head of marketing and sales at Roplast.
The company’s director, Roland Runko, adds that Roplast’s business is based on family tradition, constant investment in the company, production facilities, and people.
“We have reached the level where we can now complete large projects, which is the pride of our entire family and the entire business of the Roplast company over the last 30 years.”
Last year, they opened a new production facility where they use innovative technology for the perfect fit.


Among the novelties this year, the new Graf Synergy PVC line stands out. The latest generation of this line brings us complete automation of the process, from profile cutting and reinforcement to perfect corners, which are essentially made with the V Perfect technology patented by Graf Synergy.
This unique technology completely eliminates the visible welded joint in the corners of PVC joinery, setting new standards, and its application has no limits. Roplast uses it on all its projects.
Their desire is to provide their customers with the best, to keep up with the needs and desires of the market, but also to meet the various requirements for which that machine was needed.
“We work with a lot of individual investors, but we also work with some larger companies like InfoBip, Valamar, Kermas, Mon Perrin and similar, but I would like to point out that we have never turned down small jobs while we have done large ones, and that this is actually the result of our family’s continuous work and policy of not turning down jobs,” explains Runko.
And such a policy requires a rich offering that meets all market demands. When it comes to products, today’s customers are mostly looking for them to be of good quality, to have a modern design, that is, to meet their needs, and recently a wide range of colors has been important.


Long-term cooperation between Roplast and Deceuninck
When introducing the Deceuninck elegant system, we were guided by the criteria of fast delivery, reliability of the company itself, product quality, and availability of materials.
“We are proud of our long-standing successful cooperation with Roplast, and this year we also share an anniversary, as Deceuninck Croatia celebrates 20 years of successful business in Croatia.
Our goal is to be a reliable partner to our customers, to respond to all market demands and to provide the best service. That is why Deceuninck PVC profiles stand out not only for their quality but also for their different designs, so they can respond to any style of construction. Whether it is industrial, traditional or classic. Our profiles can also come in 57 different colors. In order to ensure this for our market, last year we opened a new production and business facility for profile lamination in Donja Bistra, near Zagreb, which is also the largest in this part of Europe. So that from this facility we can respond to all the demands of our customers and the market,” explained Dina Matić, Marketing Manager, Deceuninck.
“We have always been guided by the idea that every customer should be satisfied and that, as my father would say, even impossible situations are challenges and that in fact we have to find a solution for every case. Stefani Runko concluded.
PVC joinery now has a modern and minimalist design, and can be adapted to any project.
