Onduline Roofing Sheets

We use onduline roofing sheets on all our Heavy duty tanalised workshops and our junior tanalised workshops.

Onduline is the multipurpose long lasting & extremely tough lightweight corrugated roofing and wall cladding material manufactured from bitumen saturated with cellulose fibres under intense pressure and heat.

They say that ONDULINE® is made of paper?

Available in various colours

Available in various colours

One of the ONDULINE® components is cellulose fiber.  Cellulose fiber can be extracted from various sources, including wood pulp or recycled paper.  Besides cellulose fiber, ONDULINE® also consists of bitumen, resin, mineral additives.  Cellulose fiber itself is a very strong material (also used in cement and concrete to improve resistance).  Bitumen makes fiber water-resistant, pigments provide the coloration, resin and other additives improve weather resistance.
What is the ONDULINE® fire-resistance clasification?
In European Standards, its classification is E, which is “normal to ignite”.  It is allowed for use on different types of buildings.  But the cases when a source of fire is located on the roof are very rare.  And if a house is on fire, it means that almost every type of roof cladding burns and melts.
Does my ONDULINE® roof insulate from heat/cold?
Measurements show a thermal conductivity of 0,098 W/m.C°.  This value is close to cork.  by comparison, stainless steel value is 52 W/m.C°,525 times higher.  ONDULINE® insulates from heat and cold, within these values.
Does my ONDULINE® roof insulate from noise?  Especially in case of strong rains.

Tests carried out at the Sound Research Laboratories LTD (UK) show the good sound absorption of ONDULINE® sheetswith a value of Rw= 28 dB.The noise of rain is absorbed much better on ONDULINE® than on steel sheets.

What is the durability of an ONDULINE® roof?

Durability depends on external conditions like weather and climate.  ONDULINE® roofs are guaranteed waterproof for a 10-year period.

However, some ONDULINE® roofs have been installed for more than 50 years in Europe, and 30 years in tropical countries.

Is ONDULINE® resistant to corrosion?  To chemical products?

Because it is made of cellulose-bitumen saturated sheets, ONDULINE® resists corrosion and most chemical products.  (Laboratory tests carried out at CSTB – France)

Can ONDULINE® withstand low temperatures?

Laboratory tests in USA and Germany and the long ONDULINE® experience in Siberia (Russia) under the very low termperatures perfectly show that ONDULINE® is absolutely frost-proof with no mechanical damage.

Can ONDULINE® withstand high temperatures?

In a tropical endurance test, ONDULINE® proved suitable in severe humidity and temperatures up to 70 °C (Yarsley Test Centre – UK)

What is the maximum wind pressure ONDULINE® can bear?

Tests carried out at the Yarsley Research Centre (UK) and in Miami and Metropolitan Dade County (USA) have proved ONDULINE® suitable in hurricane and earthquake conditions (up to 192 km/h or 53,3m/s)

Does ONDULINE® contain any toxic product?  Is it safe for the people and the environment?

ONDULINE® roofs are made of bitumen + resin + mineral pigments + cellulose fibers.  None of this product is toxic for the people or the environment.  Test carried out at Yarsley Technical Centre (UK) show no toxicity of ONDULINE® sheets or ingredients.

Is it necessary to fix each sheet with 22 Safe Top Fixings?

Yes, it is necessary.  the roofing material installation can then be weather-proof for a very long period of time.  Furthermore, it will also withstand extreme weather conditions, e.g. storms.  The 1998 summer hurricane in Moscow tore off ONDULINE® sheets fastened with 4-6 nails.  Sheets fastened with 22 nails have remained undamaged.
Is it mandatory to use ONDULINE® Safe Top Fixings?

Safe Top Fixings have been specifically designed for ONDULINE® roofs.  The Safe Top Fixing bonded washer is resistant to UV radiations and with its weatherproof seal provides a superior resistance to wind uplift.  Safe Top Fixings are particularly suitable for use on hardwood purlins, and their colors match the ONDULINE® sheet colors.

Other fixings can be used, but with no ONDULINE® guarantee.

What is the temperature limit when installing an ONDULINE® roof?

Since one of the components is bitumen, ONDULINE® sheets have a tendency of becoming soft in mid-day hot sun.  Therefore we recommend making installations in the morning for hot countries.  We would recommend installing ONDULINE® roofs below temperatures of 35°/40°C (depending on the sun exposure)

Does ONDULINE® color fade?

Like everything else under the sunshine, ONDULINE® color will gradually becomes paler.  this is due to UV action.  ONDULINE® fades gradually and evenly, while the metal sheets have a tendency to lose color sporadically.
Does ONDULINE® provide other accessories?

ONDULINE® provides ridge pieces which are manufactured from the same material and to the same high specifications as ONDULINE® sheets.  Flexible double wing accommodates a wide range of roof angles.  Ridges are available in the same colors and finish than the sheets.
What is the maximum roof pitch? And the minimum?

ONDULINE® roofs can be installed from pitches as low as 5°, up to 90°.  Our Technical Department can provide all the necessary information for specific installations.
How much snow load can ONDULINE® bear?

If the battens and overlapping are made correctly ONDULINE® withstands distributed load up to 960 kg/m2.  Practically it withstands a single layer of 50cm snow load.  However, we highly recommend contacting our technical department for installation in extreme climatic conditions.
Is it necessary to clean snow from ONDULINE® roof?

If the roof construction is made correctly, there will be no problem with snow laying upon it.  If one cleans it constantly, roof could be damaged.  Therefore it is better not to do it.
Is it necessary to use under-roofing with ONDULINE®?

It is not necessary if you want just to improve the water-tightness.  ONDULINE® roof system is absolutely water-tight.  Depending on the building design and use, it may be necessary to use a vapor barrier in the roof construction.
What is the guarantee on my ONDULINE® roof?

ONDULINE® guarantees the waterproofing of its product for 15 years.  Product has to be installed according to specifications.  Guarantee is limited to the exchange of product only.
Can I walk on an ONDULINE® roof?

Like any other roof, ONDULINE® is not made to be walked on.  So you must follow the usual safety procedures when going on an ONDULINE® roof.
What is the maintenance of an ONDULINE® roof?

Mainenance is minimal.  You must just ensure that no leaves remain on the roof and trap humidity.  this has to be done for gutters anyway.
Steel roofs experience expansion/contraction issues.  Is this the same with ONDULINE®?

While steel expands and contracts under the action of heat and cold, ONDULINE® dimensional stability is not affected.  Test carried out at the French National Testing Laboratory.
Can I install ONDULINE® on a metal frame?  On concrete or wood decking?

Yes, ONDULINE® can be installed on metal frame or on decking.  The fixing must then be adapted and our Technical Department has ready procedures about this.

Can I paint an ONDULINE® roof?

ONDULINE® roofs come pre-pigmented and sometimes also pre-painted from the factory.  It is perfectly possible to paint and repaint ONDULINE® sheets, on both sides.  Oil based paint with solvents should be avoided at all times.  Please contact our Technical Department for getting the procedure.
There are stains on the sheets.  How to remove them?

Stains are made of bitumen drop and are normal.  They will be washed away with rain after a while.  Should you want to reduce them immediately, just rub another piece of ONDULINE® material against it.
Where can I use an ONDULINE® roof?

Virtually everywhere!  ONDULINE® roofs cover homes, agricultural and industrial building all around the world with colors matching the environment.
Where is ONDULINE® produced?

ONDULINE® has currently 10 factories around the world.  All factories are ISO9001 certified, which guaranties the same level of quality, wherever the production is made.
What differentiates ONDULINE® products from its competitors?

ONDULINE® offers the widest range of cellulose-bitumen sheets with various kinds of profiles, finishes and colors.  ONDULINE® uses a monolith structure which is more durable than the multi-layers sheets proposed by the competition.
What differentiates ONDULINE® Company from its competitors?

ONDULINE® has been the first company to produce cellulose-bitumen sheets on an industrial scale.  the company has been created in 1944 and has been constantly improving its products, and increasing n sales.  To date, ONDULINE® Group is the #1 producer of cellulose-bitumen sheets worldwide with a constant effort in developing and improving its products.
