ISOFLAMM® roof waterproofing system –

quality for generations

Exceeding the standards for decades 

Materials of the highest quality, long-term weather resistance, excellent durability, and safe but simple installation: the demands that Slavonia makes for its roof waterproofing membranes seem high. They can only be met by a product that stands out from the crowd.

Slavonia has realized this task more than half a century ago. Creating the first APP polymer-bitumen membrane in Austria, the company laid the foundations for a high-quality concept that revolutionised the Austrian waterproofing market. This membrane is called ISOFLAMM®. Through continuous development and improvement of its ISOFLAMM® waterproofing membranes, Slavonia has not only been ahead of the market; in fact its premium products in APP polymer-bitumen technology are better than the standards require.

APP stands for Atactic PolyPropylene. This high-quality APP roof waterproofing gets its extreme durability and robustness from the production process. An elastoplastic compound is manufactured from distilled special bitumen and selected polypropylene resins. Reinforced with two layers of polyester fleece and glass-fibre fleece it ensures excellent dimensional stability in the finished ISOFLAMM® waterproofing membrane.

As a result, ISOFLAMM® can be installed on any exposed flat roof. There is no slippage in vertical applications or heavily inclined flat-roof constructions such as saw-tooth roofs. Thanks to a temperature resistance of up to 140 °C, the roof waterproofing does not soften – a criterion that is becoming increasingly important in the face of climate change.
