Magna Tack
VShield MagnaTack Underlayment (formerly Veer PSU Plus) is a High-Temp Self Adhered Roof
Protection- used under Metal, Tile, Slate, Shakes, and Asphalt Shingle Roofs.
Features and Benefits:
- Surface: Strong polypropylene (PP) surface with UV and weather resistive coatings that add water shedding redundancy in the roofing system while protecting the structure from damage. The Surface top creates easy walkability and safety.
- All Temperature Performance: (-)40° C to 126° C; all climates, under all roofing styles.
- Weather-Tight Seal: Great Asphalt to asphalt lap system
- 100% Inorganic Surface: Synthetic construction offers long term moisture protection - won’t rot and is inert to mold growth.
- Durable: Heavy synthetic surface resists tearing during roof installation - UV stabilized surface resists UV degradation up to six months.
- Bitumen Based: Formulated for superior adhesion
