Product description

Roofing felt is a crude paperboard impregnated with bituminous impregnating agents (tar, asphaltic bitumen); it is produced in web form and supplied in rolls. Both sides are covered with mineral materials (e.g. sand) in order to help prevent the coating from running off when exposed to heat or from sticking together in the rolls and to provide protection from atmospheric conditions. A distinction is drawn between tarred board and bitumen board.


Intended use

Roofing felt is used, among other things, for waterproofing roofs to prevent ingress of moisture.

Packaging

Roofing felt is transported in rolls (e.g. 70 kg, 1.20 m in length, diameter 30 cm) wrapped in paper or in bales in crates.

Transport

Symbols

Symbol, general cargo

General cargo



Means of transport

Ship, truck, railroad


Container transport

Subject to compliance with limits for the water content of goods, packaging and flooring, roofing felt may be transported in standard containers.


Cargo handling

It is imperative that roofing felt be protected from moisture (rain, snow etc.) during cargo handling, as there is a risk of damage caused by swelling.

In the event of incorrect handling during loading, unloading and storage, there is always a risk that the relatively mechanically sensitive goods will be damaged by snagging.


Stowage factor

2.12 - 2.35 m³/t (roofing felt in 70 kg rolls, wrapped in paper) [1]



Stowage space requirements

cool, dry


Segregation

Marker pen/oil crayon (preferred)


Cargo securing

The cargo is best transported in a vertical position. If the rolls are stowed horizontally, they should be stowed only 2 - 3 layers deep in order to avoid sticking and distortion of the individual rolls.

Risk factors and loss prevention

RF Temperature

Roofing felt requires particular temperature, humidity/moisture and possibly ventilation conditions (SC VI) (storage climate conditions).

Most favorable travel temperature range: 0 - 25°C [1]

Optimum travel temperature: 20°C [1]

The product must be protected from heat sources and solar radiation as there is a risk of sticking.


Back to beginning




RF Humidity/Moisture

Roofing felt requires particular temperature, humidity/moisture and possibly ventilation conditions (SC VI) (storage climate conditions) .

Designation Humidity/water content Source
Relative humidity 75% [1]
Maximum equilibrium moisture content 75% [1]


Roofing felt must be stored under dry and cool conditions.

RF Ventilation

Roofing felt requires particular temperature, humidity/moisture and possibly ventilation conditions (SC VI) (storage climate conditions) .

Recommended ventilation conditions: air exchange rate: 6 changes/hour (airing) in order to ensure the lowest possible temperatures or if there is a risk of damage to odor-sensitive goods.

RF Biotic activity

This risk factor has no significant influence on the transport of this product.

RF Gases

This risk factor has no significant influence on the transport of this product.

RF Self-heating / Spontaneous combustion

Since roofing felt is a flammable material it should be protected from sparks and smoking must be strictly prohibited. Roofing felt can be ignited by a match flame. The ignition temperature is 365°C. When stacked, heat-induced spontaneous combustion is readily possible, with fresh roofing felt being at particular risk of spontaneous combustion.

RF Odor

Active behavior Roofing felt releases an unpleasant odor.
Passive behavior Roofing felt is not odor-sensitive.



Back to beginning




RF Contamination

Active behavior Roofing felt may cause contamination if the tar or bitumen layer is heated and liquefies.
Passive behavior Roofing felt is not sensitive to contamination.



Back to beginning




RF Mechanical influences

Roofing felt is sensitive to mechanical influences such as pressure, impact and friction.
