A regional leader
in the making of
sandwich panels
Four and a half million square metres of panel a year leave a single plant in Hrasnica — and end up on halls, cold stores and roofs across the region.
From metal trading to a line of our own
Alternativa was founded in 1997, but the business behind it is older: the Lemeš family has worked with metal through four generations, for over 120 years. It began with trading in ferrous and non-ferrous metals — the kind of work where you buy, haul and sell on.
What came after is the difference between a trader and a manufacturer: investment in machines, in the people who run them and in checking every batch. Instead of reselling somebody else’s goods, the company stood behind a declaration of its own — and that means behind every complaint as well.
Today everything sits at one address in Hrasnica: the panel lines, the warehouse and the offices. Sales and technical support work in the same building where the panel is made, so an answer from a site does not spend days travelling through somebody else’s branches. The office in Belgrade covers the Serbian market, but production has stayed here.
A panel we make ourselves is also our responsibility. That is why every batch is checked before it leaves the hall.
Mission and vision
One sentence about what we do today and one about where it leads — with nothing dressed up, because we measure ourselves against them.
Alternativa d.o.o. develops and manufactures first-rate insulating materials that make building safe, efficient and durable. Through innovation, research and partnership we keep raising the standards of the construction industry, improving sustainability and the quality of life.
As a leader in the making of energy-efficient building solutions, we go on pushing the boundaries of innovation, technical excellence and sustainable development, shaping the future of construction in the region and beyond.
Our people are our greatest asset, but the only way to release their potential is to invest in the right business systems, the ones that encourage innovation.
Numbers, not adjectives
Capacity, the floor area of the plant and the standard we work to — all checkable, unlike “the best quality”.
We make it, we do not resell it
The panel is made here, in Hrasnica, on three lines running three shifts. That is why the delivery date depends on us and not on a warehouse at the other end of Europe.
A check on every batch
The ISO 9001 quality system has been in place since 2005, and the panels are made and tested to the European standard EN 14509 — from core adhesion to reaction to fire.
Four generations behind the work
Alternativa was founded in 1997, but the work of the Lemeš family goes back over 120 years — from metal trading to making insulated panels of our own.
A panel that has been tested, not just promised
A sandwich panel is a structural element — it carries snow, takes wind and has to hold out in a fire for as long as the declaration says. That is why it is not judged by eye but tested to European standards.
