Skin

Over the rest of the semester we will be developing a series of building skins through design and prototype to construction on the Ari Bhod site. We will approach the design of a building skin as one would approach the design of clothing, as a flexible, adaptable layering membrane that augments the body it is dressing. The design of these skins should allow different bodies- sites and cabins- to be fitted and accommodated, and be adaptable to the changing climate throughout the day and seasons.

We will be designing for two scenarios: each scenario has pre-existing conditions that will function as the site for the intervention.

Scenario 1: Prototype Cabin 1: Inside-Out Lining

The first cabin built by Woodbury students in 2009 is currently 60% complete. Walls of concrete block and wood framing with polycarbonate cladding form the major exterior walls. The completion of the cabin requires construction of the roof and finalizing the exterior envelope at the entrance and window openings and insulating the cabin interior. The skin system of the Inside-Out Lining will need to be self-supporting at times and at others must attach to the existing structure.

Scenario 2: Prototype Cabin 2: SuprA-typical Shell

The existing cabins on the site are basic shelters that are currently abandoned and used as storage. Our approach in this year’s Design Build studio will be to conserve and re-use as much of the existing structure as possible, to minimize demolition, construction and waste production on the site. In order to restore habitation to the structure and extend its occupation from seasonal (summer camp) to year round the entire shell of the structure needs to be reconsidered, rebuilt and refinished. Our goal is to create a thermally insulated building envelope that also embeds the programmatic needs of the visitor into its thickness, to create a multi-functioning skin system.

Westcoat Specialty – Waterproof Products

WP – Waterproof Products

Westcoat’s waterproofing systems were engineered for incomparable moisture resistance on elevated roof and balcony decks. With unique systems for plywood and concrete substrates, Westcoat’s waterproof coatings are designed to offer both a practical and/or decorative solution for almost any elevated surface.

ALX Waterproofing System

Experience unmatched strength, durability, and design with ALX, Westcoat’s waterproof deck coating system. Formulated for plywood surfaces, the ALX system integrates the finest acrylic resins and cement blends into a reinforcing, galvanized metal lath. ALX waterproof decking system eliminates plywood seams and is ideal for use in heavy traffic areas. Developed by experienced industry professionals, Westcoat’s ALX is the first choice of the top deck coating applicators in the industry.
ALX Advantages:

ICC- Evaluated ESR-2201
Field and lab tested since 1988
Class A Fire Rating
1 hour Fire Test over 5/8″ plywood substrate- ASTM E119
Finishes available in a variety of colors, textures and patterns
Mitigates plywood seam movements
Environmentally-friendly finishes
Durable and waterproof

The ALX system stands up to heavy traffic on balconies, corridors, stairs, and interior floors. This durable waterproofing system protects surfaces from the elements.
Quick-dry installation

Apply more than one coat per day with the ALX system; an acrylic cement mixture that translates to faster drying times. The ALX system can also be applied early in the building process, allowing other trades to complete painting and stucco prior to final finishes.

Strong, resilient and tough.

By combining our sheet membrane, also known as sealguard, with 2.5 galvanized metal lath and the highest polymer content for strength and flexibility, cracking and leaking is virtually eliminated. ALX offers strength without added weight; the finished product weighs approximately 2.5 pounds per square foot.
Excellent versatility

ALX is perfect for applications from the common to the decorative. A multitude of finishes and textures satisfies discriminating contractors, architects, and homeowners. ALX can be stapled through most old deck systems for easy rehabilitation of problem surfaces. ALX works as a waterproofing underlayment for concrete, stone and tile. Also used for interior floor systems, ALX can transform plywood floors to create the look of concrete.

MACOAT Waterproofing System

Ideal for areas with heavy foot traffic, Westcoat’s MACoat waterproofing system is a fiber lath reinforced deck system engineered for use on elevated concrete and reinforced plywood walking decks. When sealed, MACoat offers a durable waterproof coating specified for use on balconies, corridors, stairs, plazas, and landings. Westcoat MACoat delivers superior durability and tough performance in hotels, condominiums, apartments, office buildings, and residential homes.
MACoat Advantages:

Waterproof
Flexible
Durable
Dries quickly allowing for fast access after installation
Wide range of colors and textures
Tough, UV resistant final coat
Environmentally safe acrylics
Safe anti-skid textured finish
Ultra lightweight

Designed for use on elevated concrete and many plywood walking decks, MACoat weighs less than one pound per square foot.
Waterproof

A combination of our fiberlath, a proprietary acrylic waterproofing resin, a specially formulated cement, and sealed with an acrylic topcoat, MACoat provides long-lasting protection and chemical resistance.
Great for old or new surfaces

Easily rehabilitate problem surfaces. In many cases, MACoat can be applied over existing deck systems, saving time and labor. MACoat works equally well on new surfaces and comes in a wide variety of colors and textures.
