THE CRS PRODUCTS INTERNATIONAL PANEL SYSTEM
This 1219 mm x 2438 mm (4' x 8') high density,
high-impact plastic laminate panel, is the heart of our product line and provides a tough
pre-finished playing surface that stands up to the rigorous demands of racquetball,
handball and squash and is virtually maintenance free.
CRS Products International offers a choice of four thicknesses of panels. As
the front wall is the key to fast solid play and conforms to the International Squash
Racquet Regulations recommended is 38 mm (1 7/16") thick and our 28.6 mm (1
1/8") for the side walls on squash and front walls for racquetball which is
manufactured of 6.35 mm
(1/4") thick 1153 kg/cu m
(72 lbs./cf) hardboard on both the playing and non-playing sides, with a 882 kg/cu m (55 lbs./cf) particle board core.
When this is combined with the 1.4 mm (0.050") 1362 kg/cu m (85
lbs./cf) density plasticlaminate surfaces on both sides, the composite panel density is an
outstanding 1041 kg/cu m (65
lbs./cf). The result is a panel with 50% higher impact resistance than the closest
competitive panel, as tested per Federal procedures. This translates into faster ball
reactions and protection against chips, dents, and cracks in the playing surfaces.
CRS side and back wall panels are normally 20.6
mm (13/16") thick; and the ceiling panels are 16 mm (5/8") thick.
Every panel is thoroughly inspected by the highest quality control standards
in the industry and machined to a corner to corner tolerance of ±0.8 mm (1/32"), an end to end tolerance
of ±0.8 mm (1/32"), and a
surface to control cut of ±0.4 mm (1/64"). These tolerances are guaranteed by CRS Products
International and are unmatched by any other system.

METHODS OF ATTACHMENT
CRS Products International panels feature two
optional systems for attachment to steel or wood framing:
PRECISION TONGUE-AND-GROVE:
Each panel is hidden-screwed through the base of the horizontal tongue into the framework,
in combination the application of superholding construction adhesive between the panel
back and each framing member. The T & G interlocking system among panels results in a
solid, non-vibrating matrix on each wall, with none of the plugs and face screw holes
associated with many other panel systems. The uniformly flush fit between panels and
framing, and among the panel joints, assures the optimum dynamics of ball impacts and
reactions for championship racquetball, handball, and squash play.
CONCEALED METAL SPINE: Here rows of metal spines are first attached to the
framing on each wall. The precision-routed backs of the panels are mounted over the
splines. As in the T & G system, construction adhesive is also used to secure the
inner section of each panel to the framing members. All the basic properties of the panel
care and plastic laminate surfaces are the same as those foe the T & G one, and today
its most important use is for applying panels directly to concrete block walls.
CRS Products International warranties both systems equally and offers
complete consultations with architects, contractors, and owners on the correct system
choice for each set of conditions.

OUTLINE OF CONSTRUCTION SEQUENCE
For at least a week prior to installing paneled
courts, the building shell should be kept at temperatures and relative humidity levels
closely approximating conditions which will prevail when the courts go into use.
The concrete sub-floor should be broom clean, finished smooth, straight and
level with maximum tolerance of 3 mm (1/8") in a 3 meters (10') radius. The concrete floor is the foundation for the completed
court, and accuracy is essential.
FASTENING OF PANELS
Once the walls and partitions are plumb, both
horizontally and vertically, the panels are secured to the studding with no fewer than
four screws per panel edge. Each stud receives a ribbon of structural adhesive the full
length of the panel creating a solid bond between panel and stud, LEAVING NO GAPS.
The ceiling panels are attached directly to 152
mm x 1.5 mm (6" x 16) gauge joists, 400 mm (16") o.c., bridging the short dimensions of the court from top
plate to top plate. This method of attachment is the same as the walls. This provides for
a totally self-supporting ceiling system with no hang wire suspension necessary. |
