Vegetated Roof, Storm Water Management, PMR, and Plaza Waterproofing Assemblies

American Hydrotech’s MM6125 hot fluid applied rubberized asphalt waterproofing membrane is over 50 years old, has been installed on over 2 billion square feet of roof decks, plazas, vertical foundations, vegetated roof assemblies, split slabs, and other structures, in the United States and over 45 countries.

With over 10 million square feet of garden roofs in place, we have a wealth of experience to offer.  Locally, we have a large inventory of over 250 green roofs, including small 1000 sq ft to large 60,000 sf plus installations.

Steep slope (12:12 pitch) engineered solutions and dead level/low slope options. 

Wind design services to ensure the garden roof stays on the roof and your client receives a wind warranty.

Green roofs begin with selection and designing the correct waterproofing membrane providing waterproof integrity of the life of the structure and end with a successful and thriving plant community.

Storm Water Management – The driving force behind the green roof movement.  Cities and municipalities are turning to green roofs as an ideal solution to site storm water management.  American Hydrotech has modeled their systems to provide accurate and quantifiable data to civil engineers for storm water design and site compliance.

LEED SRI light reflective requirements can be met using Hydroguard lightweight ballast systems.

Rainscreen Cladding Support Systems

Rainscreens provide limitless design options for building facades while controlling moisture and reducing energy consumption.  Knight Wall Systems manufactures versatile, ventilated rain screen attachment systems that accommodate an expansive array of cladding options.  Our expertise is focused on the means and methods of attaching rain screen facade panels to the building while reducing the impact on the insulation (reduced thermal bridging).  Knight offers multiple attachment solutions for different insulation assemblies:  the award winning CI® System and HCI™ System, which pair a drop-in facade attachment with rigid exterior foam insulation, enabling ASHRAE90.1-compliant continuous insulation; the ultra-sustainable MFI® System rain screen, which utilized mineral fiber insulation; and the ThermaZee high thermal performance Z.

Cladding Neutral support assemblies – Knight Wall Systems can accommodate any cladding, cladding size or design configuration and enables you to effectively design with multiple cladding materials and manufacturers on the same elevation.

NFPA 285 tested and compliant with CI, HCI, ThermaZee and MFI assemblies.

Tested and Engineered system, not just a component.

System Flexibility and application simplicity – vertical and horizontal girt variations for both CI (rigid insulation) and MFI (mineral wool) configurations.  Custom rail capability to simplify installation and reduce labor.

Single frame or double frame design?  It is critical that designers consider the cladding type, size and configuration and how those parameters impact the framing design and associated dimensions and cost implications.  Some cladding choices require a double frame support assembly which must be considered and understood during design development and especially in delegated design scenarios.

Cost effective solutions – competitive material costs combined with labor savings and simplified installation addresses contractor budgeting concerns.




Thin Natural Stone Panel Systems

Thin stone panel systems that offer building teams design flexibility, cost-savings, installation efficiencies and sustainable qualities.  Fabricated with a thin natural stone veneer that is bonded to a high-performance aluminum honeycomb backing, these cladding systems provide an alternative easy-to-install, cladding option that is both cost-effective and design-friendly.

Why Indiana Limestone?  As versatile and attractive as it is durable, limestone is well-suited for architectural finishes and sustainable construction applications for nearly any building type.  Specifically, Indiana Limestone (quarried in south central Indiana between the cities of Bloomington and Bedford) is well-known to be the highest quality limestone in the United States.  Renowned as a excellent building material due to its long-lasting strength and beauty, Indiana Limestone has adorned some of the world’s most famous  buildings, including the National Cathedral, Empire State Building, the Pentagon and 35 of the 50 U.S. state capitol buildings.

What is a Lightweight Thin Stone Panel?  Limestone thin stone panel products are manufactured in a four-layer “sandwich-panel” where a 1/4″ thick stone veneer is bonded to a waterproof fiberglass layer using an astronautical-grade epoxy that also secures the aluminum honeycomb center to the chosen backing.  This is accomplished by laminating the layer of epoxy-reinforced, fiber-rich cloth directly over the honey comb to provide crack and fracture resistance, as well as, flexural and impact strength.  The stone veneer, fiber-rich, epoxy-saturated material and aluminum honeycomb backing are then placed into a press that laminates the layers together, creating a nominal 1″ panel.  The resulting bond strength is such that it would require more than 66,200 lbs. per sq. ft. to separate the Indiana Limestone from the aluminum honeycomb substrate.

Lower Installation Costs – Lightweight at 3.5 lbs per sf, can be panelized, field applied in rainscreen applications by cladding contractors.





Fiber Cement Cladding Panels

SVK has been active on the international construction market since 1905 with its range of fiber cement facade panels, facing bricks, slates, corrugated sheets and architectonic concrete.  By continually responding to the needs of the market, the company has grown to become a flexible long-term partner for construction professionals that specialize in the residential as well as non-residential construction.

These high-density fiber cement cladding panels create unprecedented variation and combination possibilities.  Thanks t the broad colour palette, the many shapes and sizes, they fit every design.  Because they are manufactured from timeless and natural materials, they furthermore have a distinctly durable character.

Air and Weather Barrier Solutions/Drainage Planes

High drying capacity air barriers.  Simple building physics and moisture control tactics suggest that the best location for insulation is the exterior of the structure.  However, from a practical sense, many projects continue to utilize fiberglass or other insulation products to the interior side to supplement code mandated continuous insulation on the outside.  In these cases, impermeable air/vapor barriers serve to trap interior generated moisture.  Structures need to breath – they need to dry to the inside and to the outside while stopping air flow.  VaproShield has a complete product offering to solve that critical design issue.

RevealShield SA and IT – black, highly permeable (41 perms), UV stable (180 day full exposure during construction), water resistive air barrier for use with open joint rain screen products (max 40% total open wall area, joints up to 2″ wide).  RevealShield also serves to provide a weather barrier over mineral wool insulation and to protect it from moisture intrusion.

WrapShield SA and IT – for use direct to sheathing or over rigid insulation solutions.  Provides a much more efficient solution than liquid applied permeable air barriers and should be considered in lieu of or as a competitive equivalent.  No special sheathing joint treatment, no primer, ease of opening detailing.  SA provides a fully adhered application.  IT has integral seam tape and is loose applied.

WrapShield RS – A mechanically attached, water resistive (WRB) vapor permeable air barrier (AB) membrane with built-in rain screen drainage matrix and integrated tape at the horizontal seams.  3mm and 7mm drainage matrix options.
