Technical Specifications
Instructions and Guidelines
        Synthetic or bituminous membranes that are directly glued, may be laid  down in various methods. 
Mechanical fixing is recommended in synthetic membranes having low  softening or melting temperature. 
Always consult and verify with qualified and specialized personnel for specific type of applications and/or systems most suited. Also contact and obtain instructions from membranes’ producers in regards to the specific methods and application most suited with their product.
