R-Matte Plus-3

Closed-cell polyisocyanurate foam bonded to reinforced aluminum facers

N/A

Store boards indoors. Short-term outdoor storage is necessary, boards should be stored flat above grond on raised pallets, placed bondles on finished surfaces, cover with a breathable tarpaulin and secure cover to prevent wind dispplacement. 

Before beginning installation, all surfaces shall be clean and free of irregularities that will affest the placement or performance of the insulation including, but not limited to, dirt, debris, miscellaneous fasteners, or warped, defective, or otherwise damaged framing.

General Installation Instructions 

R-Matte Plus-3 must be separated from the interior side of the building by a suitable thermal barrier or ignition barrier when require. Refer to the Local Building Official for general exceptions and specific governing codes and requirement. Consult Rmax® for special testing and exceptions on thickness of 1" or less. 

All material installed over R-Matte Plus-3 (thermal barrier, ignition barrier, furring strips, interior finishes, veneers, roof systems, etc), must be mechanically attached through the insulation to the framing/structure according ot he building code. 

Walls and Ceilings

Attach insulation boards to framing or other finished surface. Staring at one corner/edg, install boards continuously and tightly abutted to cover entire surface. 

• Where insulation is cut to accomodate penetrations, voids and gapping should be minimized. Voids and gaps can be filled and sealed using a high quality insulation sealant/adhesive such as Sikaflex®-709 Insulation Sealant & Adhesive.
• When using using an adhesive such as Sikaflex®-709 Insulation Sealant & Adhesive, to secure boards, apply the adhesive to the finished surface. Press/hold the board firmly until adhesive is set. 
• When using mechanical fasteners to secure boards, use fasteners with sufficient length to penetrate framing or finished surface (minimum ¾" in wood or minimum ²⁹/₆₄" into steel). Use a minimum of eight fasteners, spaced evenly throughout the board. 
• Where multiple rows or layers of insualtion exist, stagger joints. 

When using these boards as a vapor retarder, Water-Resistive Barrier (WRB) and/or the air barrier, the following measures must be taken to ensure a complete barrier: All insulation joints, as well as any breaks or other damamge to the face in the insulation but be sealed with a pressure sensitive tape, such as SikaSeal®-148 Insulation Seam Tape or equiivalent. 

• All perimeter edges, transitions and fenestrations shall be sealed to the exterior face of R-Matte Plus-3 with appropriate flasing including, but not limited to, exposed foam edges, wall to floor, and wall to roof transitions, windows, doors, etc.
• All penetrations amde through the exterior plane of the WRB and/or air barrier shall be sealed using tape, flasing, caulk, or other water/air sealing method. 

Floors and Below Grade

Attach insulation boards to finished surface. 

• Install R-Matte Plus-3 over specially prepared based of crushed stone for slab on grade constructions or on existing slab for floor and radiant floor slab constructions. 
• Starting at one corner/edge, install boards continuously and tightly abutted to cover entire surface. 
• Where insulation is cut to accomodate penetrations, voids and gapping should be minimized. Voids and gaps can be filled and sealed using a high quality insulation sealant/adhesive such as Sikaflex®-709 Insulation Sealant & Adhesive.

Roofs

Attach insulation boards to suitable roof deck (tongue-and-groove timber, plywood, or metal deck). 

• Secure boards to roof deck with enough fasteners to hold it in place until the nailing surface or roof cover system is attached through the insulation to the deck. 
• Starting at one corner/edge, install boards continuously and tightly abutted to cover entire surface. 
• Where insulation is cut to accomodate penetrations, voids and gapping should be minimized. Voids and gaps can be filled and sealed using a high quality insulation sealant/adhesive such as Sikaflex®-709 Insulation Sealant & Adhesive.
• When using mechanical fasteners to secure the boards, use screw and plate type fasteners with sufficient length to penetrate the deck (minimum 1" into wood or minimum ¾" into steel). 

It is strongly recommended to follow the guidelines of the National Roofing Contractors Association (NRCA) when it comes to the use of a vapor retarder in any insulated roofing assembly, as well as its location within the system.
