CodeMark Certified DriStud Product System Used for Shopping Centre Extension

Commercial grade DriStud Wall Wrap used in conjunction with DriStud Cool Window Flashing Tape is a CodeMark certified product system ensuring each product meets NZ Building Code standards.

One of Auckland's largest shopping centres, Sylvia Park, is getting even bigger with its current extension project. DriStud Wall Wrap has been directly fixed to the metal cladding with Cool Window Flashing Tape which was used to join all the laps to provide the greatest level of air and water resistance.

Engineered from resilient polyester non-woven fabric, DriStud Wall Wrap is a commercial grade building wrap with one of the highest tensile and edge tear strengths on the market. Suitable for both commercial and residential buildings, DriStud Wall Wrap's high resistance to moisture makes it perfectly suited to the New Zealand climate. For projects that require high vapour permeability, an air barrier allows for high moisture vapour transfer; creating healthier and more energy-efficient structures.

DriStud Cool Window Flashing Tape is a window sealing system that can be used for sealing wall penetrations. It provides ultimate protection against water infiltration for windows, doors and thru-wall entry points. The non-asphalt adhesive ensures maximum adhesion to DriStud Wall Wrap across a wide range of temperatures, guaranteeing reliable performance in all climates.
