​​Solutions for Multifamily Residential Buildings

As our population grows and cities become more crowded, multifamily housing is key to addressing the demands of the residential market. Finding attractive ways to compress housing into smaller spaces while utilizing sustainable building practices and still creating true homes calls for a complex blend of innovative design and engineering. The following construction materials have been hand-picked by our technical experts to increase comfort, durability and safety in multifamily residential structures.

07 10 00 Waterproofing

Protect your next mulit-family residential structure against moisture damage.

To protect foundations and to waterproof between split slab applications:

• MasterSeal HLM 5000- seamless bitumen-modified polyurethane waterproofing membrane for exterior below-grade applications. DIV 07 14 16

To protect below grade concrete and masonry substrates:

• MasterSeal 581- cement based coating to help protect building interiors from dampness and moisture damage. Resistant to both positive and negative hydrostatic pressure, suitable for interior and exterior use. Excellent for waterproofing basements and retaining walls. DIV 07 16 00
  

07 18 00 Traffic Coatings & Deck Membranes

Specify a waterproofing system to help protect wearing surfaces from pedestrian and or vehicular traffic abrasion, as well as to protect concrete from scaling and chloride intrusion.

To protect balconies, exposed concrete stairs and walkways:

• MasterSeal Traffic 1500- waterproofing membrane system that is ideal for light to medium duty traffic. DIV 07 18 16 

For elevated decks:

• MasterSeal Traffic 2500- waterproofing membrane system that provides excellent waterproofing and protects the occupied spaces below. DIV 07 18 16
  

07 24 00 Exterior Cladding & Masonry Veneer Systems

Senergy continuous insulation cladding systems provide nearly endless aesthetic possibilities- wood, metal panel, granite, limestone, etc- while saving the owner energy costs. We can turn your creative inspiration into a beautiful, sustainable, fully engineered cladding system that has the building science you need, at a cost that meets the demands of your budget. Find the details you need to bring your design to life​.

Considering multiple claddings on a project? Check out our latest innovation- Senergy Insulated Veneer Systems. Design a high performance building enclosure that requires NO mechanical fasteners, has no thermal bridges, and  provides the look, feel and durability of masonry with the air/water-resistive barrier, continuous insulation, code compliance and economics of EIFS. (DIV 07 24 23)

07 27 26 Fluid-Applied Membrane Air Barriers

Air intrusion into a structure can cause moisture and condensation to collect in walls; which can lead to significant problems for the client (mold & mildew, poor air indoor air quality, structural damage). To manage and control moisture in your wall systems and building envelope, it is critical to understand where the dew point will be (inside or outside the wall). 

For conditions that require a vapor permeable air/water-resistive barrier: 

• MasterSeal AWB 660 – fluid-applied air/water-resistive barrier prevents air leakage and should be continuous throughout the structure. Qualify as both an air/water-resistive barrier and flexible flashing material. DIV 07 27 26

For conditions that require a vapor impermeable air/water-resistive barrier:

• MasterSeal AWB 660 I – fluid-applied air/water-resistive barrier that can also function as a Class 1 vapor retarder. Provides excellent secondary moisture protection behind most wall claddings including brick, siding, metal panels EIFS and stucco. DIV 07 27 26

07 92 00 Joint Sealants

The integrity of a structure is often only as good as the sealants used as moisture will find a way between two surfaces at the joint.

For windows, doors and siding applications that need to bond to concrete, masonry units or porous substrates: 

• MasterSeal NP1- polyurethane sealant with movement capability ±35%, VOC content = 35 g/L, VOC compliant for interior use per LEED v.4 Low-Emitting Materials. Suitable for immersion in water. 13 standard colors. DIV 07 92 13 
  

For coated metal applications (PDVF coatings):

• MasterSeal NP 100- hybrid sealant that combines polyurethane & silicone properties with movement capability ±50%, VOC content = 29 g/L; VOC compliant for interior use per LEED v.4 Low-Emitting Materials.  CDPH v1.1 compliant. 14 standard colors with 40 stocked tint bases available. DIV 07 92 13 
  

To help contril noise: 

• MasterSeal NP 520 – siliconized acrylic latex sealant to seal sound flanking paths in partition walls, fire-rated, meets Class A criteria set by NFPA 101. VOC content= 13 g/L, VOC compliant for interior use per LEED v.4 Low-Emitting Materials. 11 standard colors. DIV 07 92 19

07 95 00 Expansion Control from Watson Bowman Acme

Superior performance and sleek design can go hand in hand. To simplify the decision-making process, we recommend starting with these interior floor joints:

• Wabo® Corridor Wrap Floor - accommodates 1”-4” movements, interior floor joint system, economical and comes in 4 standard colors, accommodates a variety of flooring materials. Coordinating wall and ceiling systems available. 
  
• Wabo® SeismicPan - accommodates 2”-24”, finished floor can be included to create a less visible joint
  

To maintain the integrity of the interrupted fire rated assembly and prevent the spread of fire:  All systems tested to meet appropriate UL, ASTM, NFPA, ICBO, and CAN/ULC guidelines. All joint systems can be fire rated by combining the selected system with one of Watson Bowman Acme’s fire rated syst​ems.

• Wabo® Fire Flex- 2hr fire rating, for multidirectional movements and vertical or horizontal applications
• Wabo® Flame Guard II- 3hr fire rating, for vertical, horizontal or under slab applications
  

For fire protection that creates a watertight seal with adjoining structures: 

• Wabo® Fire Shield - 2 or 3 hr fire rating, ideal for vertical or horizontal situations where the new construction connects to another structure (new to existing, new to new, building to plaza area, building to parking structure, etc.)
