Sustainable roof & wall cladding
SVK always subjects its products to extensive durability tests. The tests will extensively test influences of moisture, frost, rain and sun.
Under normal circumstances, current testing standards allow a strength loss of up to 25% after such durability tests. SVK products, however, have virtually no strength loss. This allows us to say that our material is a quality product that can still guarantee the same quality after many years.
Sustainability tests
Following extensive tests our products undergo to demonstrate durability.
| Test | Total number of test hours | Testing method |
|---|---|---|
| Freeze-thaw | 600 h | Materials undergo successive cycles from -20 °C to + 20 °C in wet conditions |
| Wet-dry | 1200 h | Materials undergo successive cycles of full immersion in water followed by drying out at 60 °C |
| Hot water | 1344 h | Materials are immersed in water at 60 °C for 56 days |
| Heat-Rain | 300 h | Materials are undergone successive cycles of sprinkling followed by IR irradiation of 60 °C |
| Q-sun | 2000 h | The painted surface of materials is exposed to cycles of UV radiation and condensation for 2000 hours |
Reuse of fibre cement
Fibre cement materials that have been mechanically fastened can easily be loosened. If they are not damaged, they can be reused without any problems.
The raw materials used in our fibre cement products are harmless to the environment and can also be used in ground form as inert additives. SVK already does this with waste materials generated during production (e.g. by sawing, rejected materials).
Maintenance-free façade cladding
Our materials are all low-maintenance. Our coated slates and wall cladding panels contain moss-repellent components that inhibit moss formation.
Moreover, our cladding panels have a smooth surface which makes it difficult for dirt to adhere to them. This makes them low-maintenance. Our cladding panels are easy to clean with water and a neutral all-purpose cleaner.
Roofing maintenance
The importance of well-maintained roofing
The roof is one of the most exposed parts of the house and is all too often forgotten when it comes to maintenance. Over time, deposits of dust and atmospheric pollution occur on all roof coverings. All the more so on low roof pitches and long roof areas, where dust is less easily washed away by rain. These conditions promote moss formation. In addition, the "acid rain" on the roof provides the acidic environment in which mosses and algae thrive.
Mosses develop mainly on the parts of the roof that have little or no exposure to the sun, such as on roof shields facing north or that are perpetually shaded. Proximity to trees or greenery obviously also has an adverse effect. A lack of ventilation of the space under the fibre cement boards and the structure behind them also promotes moss growth. Indeed, good ventilation reduces the amount of moisture in the roofing.
Mosses adhere to all types of materials on which dust and dirt have been deposited.
Rot and rust resistant
The composition of fibre cement ensures that the material itself will never rot or rust. The fibres and fillers are embedded in cement, which makes the material resistant to living organisms such as mould, bacteria, insects and pests.
hydrophobic protective coating
Extra protection for your facade with a hydrophobic protective coating
Our thoroughly coloured facade panels are sanded and then hydrophobised. This gives the board another water-repellent, transparent, matt protective layer. The hydrophobing protects the boards from water and dirt and makes them low-maintenance. The protective coating slows down the natural ageing process.
