Metal dowel with washer 8x140mm fireproof for wadding VESTAL

The VESTAL brand metal dowel for thermal insulation is a specialized anchor element designed to ensure uncompromising mechanical stability of facade systems with stone and mineral wool. Made entirely of steel, this dowel is completely non-combustible, which is of critical importance for the fire safety of high-rise buildings and industrial sites. It acts as a primary mechanical support that complements the adhesive and ensures that heavy insulation boards will remain firmly fixed to the base, regardless of wind force, material weight or sudden temperature amplitudes.

The model comes complete with a wide metal washer, which plays a key role when working with fibrous and soft insulation materials such as wool. The washer distributes the pressing force over a larger area, thus preventing the dowel from sinking into the surface and ensuring a perfectly smooth surface before applying the putty layer. Thanks to its all-metal construction and galvanic coating, the VESTAL dowel provides long-term strength and reliability, eliminating the risk of aging of the fasteners and subsequent peeling of the facade system.

Purpose:

• Mechanical fixing of heavy and non-combustible rock and mineral wool insulation boards
• Additional reinforcement of EPS and XPS thermal insulation systems in areas with high wind load
• Anchoring to solid building foundations such as concrete, solid brick and natural stone
• Providing fire-resistant anchorage points in public and industrial buildings

Main advantages:

• Guaranteed non-flammability and high fire safety thanks to the all-steel housing
• Wide metal washer included to ensure stable clamping of soft insulation materials
• High resistance to corrosion and weathering, ensuring decades of service life
