SIDERISE EW systems have been developed to provide a simple and easy to install method of sealing external wall cavities for both masonry and timber frame constructions.
The standard range has been optimised to include options of materials that are cost-effectively matched to suit the specific performance criteria for all fire stopping requirements. Additionally, the products have excellent sound reduction qualities which can be used to combat unwanted noise via flanking transmission.
These products represent an ideal combination of fully qualified performance, practical installation and cost effectiveness.
Note: This product was previously known as Lamatherm EW systems - cavity barrier, firestop and acoustic barrier solutions for external walls.
