CLM 50 membranes are high-performance, elastomeric (SBS) bituminous membranes. They are non-reinforced and have excellent elasticity, with an elongation of more than 1000% and more than 90% elastic recovery.
These membranes are specially designed for high rates of expansion and offer superior elongation.
They are durable and easy to apply, with remarkable resistance to aggressive attack from salts and chemicals.
The CLM membranes can be used as a single or double layer for inverted roofing in pre-cast buildings with high expansion.
They are also suitable for expansion joint reinforcement and can be used for waterproofing and damp-proofing applications in basements and roofs.
It is recommended to use double layers in basements.
The membranes should be installed loose-laid by torch welding, with only the lap joints, areas around penetrations, upstands, and a 30 cm wide strip around the perimeter fully bonded.
The CLM membranes are available in rolls of 10x1 or 8x1 meters and can be supplied with different surfacing options.

What makes CLM 40 & CLM 50 membranes non-flammable and how does this contribute to their performance?
The non-flammable nature of CLM 40 & CLM 50 membranes contributes to their performance by enhancing their safety and durability. Being non-flammable means that these membranes have a high resistance to fire, reducing the risk of ignition and spreading of flames. This is particularly important in construction applications where fire safety is a critical concern. The non-flammable property of these membranes ensures that they can withstand exposure to high temperatures without catching fire or releasing harmful gases. This enhances their overall performance and reliability, making them suitable for use in various roofing and waterproofing applications.
Could you explain the significance of the elastomeric (SBS) composition in CLM 40 & CLM 50 membranes?
The elastomeric (SBS) composition in CLM 40 & CLM 50 membranes is significant because it provides several key benefits.
1. High Elongation: The elastomeric compound allows the membrane to have an elongation of more than 1000%. This means that the membrane can stretch significantly without tearing or losing its integrity.
2. Elastic Recovery: The elastomeric compound also enables the membrane to have more than 90% elastic recovery. This means that after stretching, the membrane can return to its original shape and size, providing long-term durability and performance.
3. Superior Expansion Resistance: The membranes are specially designed for high rates of expansion. This makes them ideal for use in applications where there is a need for flexibility and resistance to movement, such as in inverted roofing for pre-cast buildings with high rates of expansion.
4. Resistance to Salts and Chemicals: The elastomeric composition provides remarkable resistance to aggressive attack from salts and chemicals. This makes the membranes suitable for waterproofing and damp-proofing applications in basements and roofs, where exposure to moisture and chemicals is common.
Overall, the elastomeric (SBS) composition in CLM 40 & CLM 50 membranes ensures superior performance, durability, and resistance to expansion and chemical exposure.
How do CLM 40 & CLM 50 membranes demonstrate high durability and resistance to UV radiation?
The factors that contribute to the high durability and resistance to UV radiation of CLM 40 & CLM 50 membranes are:
1. Elastomeric Compound: The membranes are made of a high-performance elastomeric (SBS) bituminous compound. This compound provides excellent elasticity, with an elongation of more than 1000% and more than 90% elastic recovery. This elasticity allows the membrane to withstand the expansion and contraction caused by temperature changes, making it highly durable.
2. SBS Modification: The coating asphalt used in the membranes is SBS modified asphalt. SBS (Styrene-Butadiene-Styrene) is a synthetic rubber that enhances the properties of asphalt, making it more resistant to aging and UV radiation. This modification increases the membrane's resistance to degradation caused by exposure to sunlight.
3. Resistance to Salts and Chemicals: The CLM membranes have remarkable resistance to aggressive attack from salts and chemicals. This resistance ensures that the membranes can withstand the corrosive effects of these substances, further enhancing their durability.
4. Application Method: The membranes are installed using torch welding, which allows for full benefit from the superior elasticity of the membrane. This method ensures proper bonding at lap joints, areas around penetrations, upstands, and the perimeter of the work. The fully bonded areas provide additional protection against UV radiation and enhance the overall durability of the membranes.
In summary, the high durability and resistance to UV radiation of CLM 40 & CLM 50 membranes are attributed to the elastomeric compound, SBS modification, resistance to salts and chemicals, and the application method used.

Are there any specific installation requirements or techniques that need to be followed when working with CLM 40 & CLM 50 membranes?
The CLM 40 & CLM 50 membranes should be installed using torch welding to take advantage of their superior elasticity. Only the lap joints, areas around penetrations (such as pipes), upstands, and a 30 cm wide strip around the perimeter of the work should be fully bonded. AWAZEL PRIMER D 41 should be applied to areas where full bonding will occur. Upstands and flashings should be installed using 1m wide pieces cut from the length of the roll. The membrane should be loose-laid, and double layers are recommended for basements.
