Why Choose SVK Neptunus Corrugated Sheeting?

Strongest Corrugated Sheets Available

SVK Neptunus Corrugated sheets are the strongest sheets available on the Irish market. No other fibre cement sheets come close to our standards for bending strength. This is achieved because SVK uses and sources only fibres of the highest quality, and because of our unique process of double-compressing sheets during production. SVK corrugated sheets, 6.5mm thick, are of the strongest class – Class 1 – in accordance with the European Standard EN 494. They offer the most comprehensive range of certification, underpinning their quality and reliability.

Superior Paint Finish

SVK uses a superior paint finish on the edges and surface of the Neptunus range. Their coating is characterized by its high-quality finish and its ability to retain its colour. This is thanks to outstanding paint adhesion, and decades of experience in paint production.

All Paints used by SVK are manufactured on-site.

Long Life Span

Neptunus Corrugated Sheeting’s lifespan is tested to 50+ years. This is achieved using specially selected high-quality fibres and raw materials.

Pre-Mitred Sheets

Neptunus Corrugated sheeting has the unique fitting advantage of being a pre-mitred sheet. All SVK sheets, with the exception of spaced sheeting, are pre-mitred. This can reduce the fitting time by up to 30% and in turn reduce fitting costs.

Fire Resistance

Neptunus sheets are tested according to the European Standard EN13501-1 and are class A2-s1.


Neptunus sheets have a Polyethylene strip placed through each corrugation during construction. This not only strengthens the sheet but also acts as a safety barrier should an accident occur.

Sound Insulation Properties

The noise of heavy rain or hail is radically reduced by Neptunus sheets.

Rust and Rot Resistant

Fibre cement sheeting contains no metal or materials that are prone to corrosion. This has a unique advantage over metal sheets, which are prone to rust when the protective layer is damaged or perforated.

Grant Approved

Neptunus corrugated sheeting is Department of Agriculture grant approved.


Neptunus sheets do not drip, thanks to the raw nature of fibre cement. It absorbs the humid air and moisture inside the building, gradually releasing it into the outside air.

Composition and Manufacture

All Neptunus Corrugated sheets are double-compressed fibre cement sheets composed of PORTLAND cement, superior-quality organic fibres, mineral additives and water. This unique second pressing is what makes SVK corrugated sheeting the strongest on the market. Coloured  sheets are finished with a multi–layer acrylic based coating, counteracting the growth of moss. All Neptunus sheets are coated with a colourless water-repellant resinous layer offering optimal protection under all weather conditions.
