How construction boards are used in the building industry
Our StrongBoards construction boards are ideal for both new construction and renovation projects. With their high strength and excellent moisture resistance, they are perfectly suited for flooring systems, wall partitions, roofing structures, and various infill applications. HSD and JSD boards are fully certified for construction use and comply with all relevant Czech and European standards.
Flooring boards
JSD and HSD boards offer a reliable solution for dry floor systems. They stand out for their strength, dimensional stability, and easy workability. In addition to standard solid boards, we also offer JSD boards with milled grooves for underfloor heating or cooling – a certified system that enables quick and precise installation of heating pipes.
Water flowing through the pipe can provide heating in winter and cooling in summer. The entire structure is ready to be covered, allowing for quick installation and high comfort without the need for wet processes. An ideal choice for new buildings, renovations, and modern timber constructions.

Boards for structural applications
JSD (P5) and HSD (P7) boards are a reliable material for versatile construction use – from building interior elements to structural applications. Thanks to their high strength, dimensional accuracy, and moisture resistance, they are perfectly suited for subfloor structures, infill panels, partition walls, and exhibition systems..
One of the common applications is also their use as permanent formwork. The HSD variant is also ideal for more demanding conditions where higher density and load resistance are required.
Easy processing (cutting, drilling, anchoring) makes JSD and HSD boards a flexible and efficient solution for modern construction.




JSD board with integrated heating/cooling system – a certified solution for modern flooring
Special variant of the JSD board with milled grooves for underfloor heating and cooling offers an innovative and efficient solution for dry floor systems. The grooves are precisely milled to hold the heating pipe, which can be used both for hot water heating, as well as for water-based interior cooling.
The entire system is certified, ready for immediate installation and compatible with a top layer for final floor finishing. It allows for quick installation without wet processes, saving both time and costs, and is ideal for new builds, renovations, and timber constructions.
This structural element combines the benefits of high-quality building material with modern comfort – in a single step, you get a solid subfloor and a functional heating/cooling system.

JSD and HSD boards for timber construction
JSD (P5) and HSD (P7) boards are the ideal component for structural solutions in timber constructions – whether for wall cladding, infill structures, frame reinforcement, or covering ceiling and floor elements. Thanks to their high strength, dimensional accuracy, and shape stability they are a reliable alternative to OSB boards, with the added benefits of easier processing and improved stability.
Option HSD with higher density offers even greater resistance to mechanical stress and moisture, making it suitable for more demanding applications in exteriors or areas with higher loads.
The boards can be easily cut, drilled, milled, and anchored, ensuring fast installation without the need for complex tools. Thanks to these properties, they are ideal not only for frame systems but also as a stable base for drywall, façade elements, or floor assemblies.
They are a proven choice for construction companies and manufacturers of prefabricated modular timber buildings who are looking for an efficient and structurally reliable solution.
A practical and reusable solution – boards for lost formwork
JSD and HSD boards have proven to be excellent as temporary formwork for concreting foundations, bond beams, stairs, or columns. Thanks to their strength and durability, they can withstand the pressure of fresh concrete, and after curing, they can be easily dismantled and reused.
Advantages of use:
- High strength and moisture resistance
The boards reliably maintain their shape and withstand even the toughest conditions on the construction site. - Easy processing and handling
Cutting, drilling, and installation can be done with standard tools, without any special modifications. - Reusable design
After dismantling, the boards can be reused in other parts of the construction – an efficient and cost-effective solution. - Time and costs savings
Quick installation and dismantling reduce labor time and save on material costs.

FAQs
Can JSD and HSD boards be used in dry floor systems?
Yes, both JSD and HSD boards are ideal for dry floor systems – as a load distribution layer or top covering. They are strong, stable, easy to work with, and resistant to moisture.
Are JSD and HSD boards suitable for timber construction?
Absolutely. Thanks to their stability, strength, and easy workability, the boards are well-suited as part of the structural system in timber constructions – for example, for wall cladding, ceiling coverings, or reinforcement of frame structures.
Are JSD and HSD boards suitable for use with underfloor heating systems?
Yes, JSD and HSD boards can be used as a load-bearing layer over underfloor heating systems as part of dry floor systems. Additionally, we offer a certified system with milled JSD boardswhich allows for the direct placement of heating pipes for heating or cooling. The entire system is ready for quick and reliable installation.
Can JSD and HSD boards be produced in custom dimensions?
Yes, we offer custom manufacturing including individual dimensions, thicknesses, and surface finishes as well as tongue-and-groove edging.
