One System, One Specification, One Supplier

The Marshall Weatherization System is a pre-cladding system comprising of six highly compatible components — which have been carefully selected for their high-performance criteria and suitable integration properties:

Tekton Wall Underlay
Hydra Wall Underlay
Hydra Roof Underlay
Super-Stick or ProSill Tape
Seam Tape
Trade-Seal

Together they create a weathertight system which combines superior strength, water hold-out and flexibility with ease of installation. The Marshall Weatherization System (MWS) is designed as a secondary line of defence in case of water penetration through the roof or wall cladding.

Tekton is a synthetic, non-absorbent, breather-type coated, spun-bonded polypropylene with a superior Flammability Index Rating (= 0) and outstanding tear strength. This underlay acts as a secondary line of defence and also provides protection of the framing/building structure for up to 60 days during construction.

Tekton Seam tape is used as an extra level of watertight protection for sealing where underlay joins overlap; this is a requirement of the MWS as per system specification.

HYDRA Wall is a synthetic, absorbent, breathable, fire retardant flexible underlay which can be used behind all wall claddings (absorbent/non-absorbent claddings in both direct and non-direct fixing).

HYDRA Roof underlay — a new addition which completes the Weatherization System (protection of complete building envelope) is an absorbent, self-supporting, breathable, fire retardant flexible underlay, suitable for use with most roofing types, and both timber and steel framed buildings. This tri-laminate, synthetic, non-woven roof underlay is outstanding in bright blue, and is also 100% recyclable.

Super-Stick and ProSill are high-performance flashing tapes used for effectively sealing around window and door openings, each with their own unique sealing and adhesion properties for varying installation applications. Super-Stick is also commonly used for RAB Board sheet joins (in residential, commercial, healthcare, retirement and education projects throughout NZ) and is often the preferred tape choice by builders especially for use with JH RAB board in the Auckland market.

All electrical, plumbing and service penetrations are effectively sealed using the Marshall Trade-Seals — which are a BRANZ-appraised, one-piece self-adhesive collar available in a range of sizes 8mm – 220mm. Trade-Seals can be used with both flexible and rigid underlay types; and can be exposed to UV for up to 90 days (during construction).

Marshall Innovations range of weathertight construction solutions each carry their own independent BRANZ appraisal; the Marshall Weatherization System has been BRANZ appraised as one complete system.

Marshall Innovations now offers the specifier a single point of contact, and a complete technical specification to simplify the design process, backed by a 50-year durability warranty.
