System insulation board IVAR.ST 30 AL for dry system – 30 mm, 1200 × 600 mm (0.72 m²)
Code: ST30ALProduct detailed description
The IVAR.ST 30 AL (code ST30AL) is a system insulation board for water underfloor heating in a dry system. It suits situations where a concrete screed or self-levelling compound is impossible or unsuitable – renovations in which a screed would overload the structure, moisture-sensitive timber buildings, or where the available build-up height is low.
Board properties
- thickness 30 mm, format and usable size 1200 × 600 mm = 0.72 m²
- for PE-RT 16 × 2 mm pipes at a laying spacing of 150 mm
- the 100–200 µm aluminium surface layer spreads heat across the area
- EPS 300 insulation: thermal conductivity λD 0.0318 W/mK, thermal resistance RD 0.95 m²K/W
- reaction to fire class E, in accordance with DIN EN 13163
Floor build-up
Gypsum fibre floor boards are laid on top of the board – the manufacturer recommends Fermacell or Knauf in 25 mm, onto which ceramic tiles can be bonded. Under laminate a 12.5 mm gypsum fibre board is sufficient. Where the lowest possible build-up is needed, the system with the 20 mm ST20AL board reaches a total height of 45 mm excluding the final covering. On a stable, load-bearing base, ceramic tiles can also be laid directly on the board. Compared with the 20 mm board, the ST30AL offers higher thermal resistance (0.95 instead of 0.65 m²K/W).

Frequently asked questions
Do I need a concrete screed with this board?
No. The board is intended for a dry system in which gypsum fibre floor boards replace the screed – the manufacturer recommends Fermacell or Knauf in 25 mm.
Which pipes are laid in the board?
PE-RT pipes with an outside size of 16 × 2 mm at a laying spacing of 150 mm.
What is the difference between the ST20AL and ST30AL boards?
ST20AL is 20 mm thick, made of EPS 400 with a thermal resistance of 0.65 m²K/W. ST30AL is 30 mm thick, EPS 300, with a thermal resistance of 0.95 m²K/W.

IVAR designs, develops and manufactures highly energy-efficient heating and plumbing systems. We have over 10,000 catalogue items - mass-produced products and unique items - in addition to customised systems and combinations of complex products. And it’s all “Made in Italy”.
Vision
To make life easier for our clients, our clients' customers and our employees, thanks to our ability to be constantly innovative.
Mission
To design and manufacture advanced hydronic solutions that reduce installation complexity and energy consumption.
“Made in Italy” adds value
IVAR has been producing heating and plumbing system components since 1985: valves for heating bodies, direct heat metering modules, heat cost allocators, pipes and fittings, substations for heating systems, distribution manifolds, radiant panel systems, and components for solar and geothermal systems. And it’s all “Made in Italy”.
Over 200 people are employed at our manufacturing facilities in Prevalle (in northern Italy’s Brescia province). The site has been designed to streamline our many production and operational stages.
The Italian headquarters also acts as a hub for the wider IVAR Group, set up with the goal of distributing products beyond Italy’s borders. The group now has 11 branches, in Australia, Belgium, China, Germany, the United Kingdom, the Czech Republic, Romania, Slovakia, Spain, the United States and Tunisia.
Know How
Research, development and numerous laboratory tests guarantee that our clients’ requests can be translated into new high-efficiency products.
The stages required for production take place internally, beginning with hot forming, which is carried out at our subsidiary Valmon Stampati. Our continuous implementation of projects under the Industry 4.0 initiative also allows us to take full advantage of new releases in technology and IT to improve our manufacturing efficiency.
As a company, IVAR is constantly evolving. Every day, we invest in strengthening our products, in improving our production processes and in attaining new patents and certifications.
