Applications


Interior Masonry Walls
Quick, easy installation.
New or retrofit applications.
Moisture resistant.
Long-term performance.

RayLite insulation can be applied to interior masonry or concrete walls with several attachment techniques.  RayLite is used with either "Z" channel furring, wood furring strips, or several formed metal strip systems.  RayLite is also available as StyroStud with integral wood furring strips.  StyroStuds are available with 16" or 24" o.c. furring strips.

Stucco/Exterior Finish Insulation
New or retrofit applications.
Excellent moisture resistance.
Low maintenance.
Reduces air infiltration.

Exterior insulation systems are an ideal way to completely wrap a building in a durable insulation package that eliminates air and water infiltration.  Tough stucco or EFIS finishes over RayLite aged board insulation (ABI) provide an attractive, low maintenance building finish.  RayLite ABI may be cut into many special shapes for use as cornices, arches, columns, or virtually any shape you can dream of.

Masonry Cavity Walls
Resists moisture penetration.
Fits tightly between ties.
Easy to cut and install.
Long-term insulating value.

RayLite can be used to provide a durable insulation barrier between inner and outer cavity walls.  RayLite is available in 16", 24", and 48" x 96" size boards.  Simply impale the RayLite insulation on wall ties or use spot adhesives as outer wall is laid up.  Maintain 1/2" air space between RayLite and outer wall for optimum moisture resistance.

Roofing Insulation
Thermal efficient, low cost insulation.
Excellent long-term R-values.
Tapered for positive drainage.
Compatible with many membrane systems.
U.L. listed, FM approved.

RayLite is an excellent choice for roofing applications.  It has superior long-term thermal and moisture characteristics and can be tapered to provide positive slope to drain.  DiversiFoam Products has a complete engineering staff available to provide technical assistance and detailed shop drawings.
