1. WHY A SLATTED
As a swimming pool owner the importance of
keeping a pool covered is of paramount effect for maintaining
/ minimizing of water evaporation / heat retention and
The slatted cover is considered to be superior
over the normal “BUBBLE” or “SHEET” types
of covers available and is generally considered to be a
permanent solution in the covering of a swimming pool.
operation (either manual or automatic) its ease of use
must be considered of utmost important to the owner.
Its lifespan of 10 Years (minimum) easily offsets the
initial capital costs incurred.
The slatted type cover,
being Individually made to suit a particular swimming
pool, ensures customer satisfaction
at the outset.
Availability of various colour options
/ in or above ground variants / manual or automatic operation
allows for the
option most suited to your particular environment.
2. THE PRINCIPLES OF OPERATION
of the slatted cover is such that the cover “FLOATS” on
the surface of the water and fits snugly under the coping
edge surrounding the swimming pool.
In manual design the cover
is easily operated by an individual
person and has NO connecting ROPES or fixing HOOKS to contend
with. The manual design is specifically for ABOVE pool operation
and is considered to be the easiest system for existing swimming
pools. Simply fitted at one end of the pool it is securely
mounted in a permanent position.
In automatic design the cover
is simply operated by a purpose designed motor which is either
KEY operated, or, in the DELUXE
version by simply using a REMOTE. (Similar to the operation
of a garage door or electric gate).
the system has NO connecting ROPES or fixing HOOKS to contend
with. The automatic design is suitable for use on both
ABOVE or IN pool operation and is considered to be ideally
suited to new swimming pool construction.
Manual systems fitted
to ABOVE pool systems CAN be converted at any stage to being

4. HOW THE “ROLL A SLAT” WORKS
can be seen from the above variants the slatted pool cover
simply UN-COILS itself onto the waters surface, travelling
toward the opposite end of the pool, until the whole pool
All individual slats are inter-connected to each
other and when uncoiled are gently pushed from the coiled
end to the
opposite end as the roller system is operated manually or
As the slats are individually purpose made to
suit a particular pool size it is ensured that the whole pools
As the slat widths are made to the exact requirements
of the pool, fit under the coping edge surround, no unsightly
are seen, due to poor fitment or cutting, as can be found
with use of other types of cover material.
5. POOL VARIATIONS
Traditionally pool construction
in South Africa has tended to be towards irregular shapes,
large in overall size, and
generally sited away from the main house / entertainment
Over the last decade these traditions have changed
considerably and recent pool construction tends to be of more
smaller in overall sizing, sited in close proximity to the
main house and are generally a full time part of the home
Heating and covering of Swimming
Pools is now commonplace and the slatted pool cover designs
are ideally suited to this
type of construction and environment. Its HEAT retention
properties are, due to its design, ideally suited to those
Although every type and size of pool cannot be
detailed in these pages the most common variants are as indicated
Non-standard shapes CAN be catered for subject
to prior Inspection.
Roll-up Position and direction are generally
as indicated above.
On rectangular and Square pool shapes,
the Roll-up can be located at either end but DEEP end use
is recommended as the
Roll-up station’s will generally be “FIXED” in
position at the time of installation.
Slatted type covers
for new pool construction can most easily be inbuilt at

A SLAT” and swimming pool can be a packaged design
to suit the conditions of the client.
Growing in popularity
is the design of pools using an OVERSPILL
system for great aesthetic looks. The “ROLL A SLAT” is
ideally suited to this type of construction, as it will NOT
tend to fall over the OVERSPILL section.
6. SLAT MATERIAL / DESIGN
The slats used in the “ROLL A SLAT” system are
made from a high grade ‘u’ PVC rigid material
fully UV (ultra-violet) stabilized material ensuring long
durability suited to the harsh South African weather conditions.
slat is individually made to a predetermined width and sealed
at time of factory assembly with a specially designed “END
CAP” to ensure that the slat does not allow water to
enter into its cavities thus ensuring utmost buoyancy when
installed on a swimming pool.
The end cap serves as an added
buffer-protection to the individual slats from scraping against
the swimming pool sides.
Each slat has three (3) individual
cavities across its entire length, which, being AIRTIGHT
allow for good insulation against
heat losses whilst providing for some partial additional
heating for the pool water.
Although the standard (and most
common) colour is ‘OFF-WHITE’ the
other standard colours available are ‘LIGHT BLUE’ and ‘MID
In fact the “ROLL A SLAT” could be
provided (on a made to order basis) in a range of colours
to suit specific
7. ROLLER SYSTEMS
The roller system is supplied
in two (2) formats, being 1, for ABOVE POOL and 2, for IN-POOL
For the above ground system the main
roller tube is ALUMINIUM with all hardware / shafts, bolts
Etc being Stainless Steel.
The side mounting plates are generally fabricated from mild
steel plate which is then galvanized and finished with an
electrostatic epoxy power coating, protecting against corrosion
chemicals / salt water (as in salt chlorinated pools).
stand assembly is, after assembly, enclosed by means of a
cover fabricated from a UV stabilized ABS (plastic) cover
to prevent contact with any moving parts by the user.
installed “ROLL A SLAT” system is used
on outdoor pools a variety of cover designs can be supplied
as added protection against UV conditions when the cover
is to remain in the rolled-up position for long periods.
indoor pool applications this is not considered to be a
standard requirement. (IN POOL)
The IN-POOL design main roller
tube is STAINLESS STEEL, or, in certain cases, PVC coated
anodised Aluminium (not suitable
for salt water chlorinated pools).
All other components are
standard supplied in STAINLESS STEEL or a PE (polyethylene)
synthetic material to prevent corrosion.
DRIVES ARE ALWAYS FITTED EXTERNALLY TO THE POOL
PREVENTING ANY POSSIBLE ELECTRICAL CONTACT WITH SWIMMING
8. MOTOR DESIGN
If the AUTO option is used the
MOTOR drive is of a totally enclosed design operated by a
12 Volt DC motor. This motor
is suitable for operation in Swimming Pool environments and
does NOT pose any possibilities of electric shock.
Volt motor circuits have a battery back up for use when mains
power has failed or tripped for any reason. This
ensures that the “ROLL A SLAT” will never be
inoperable when mains power is unavailable.
As an added feature
each MOTOR drive is fitted with a CLUTCH
mechanism that if mains and battery power fails the cover
can be pulled on or off the pool manually.
The design of the “ROLL A SLAT” pool
cover is intended to be a permanent solution to effectively
the full benefit of your swimming pool.
Effective in not only
keeping your pool clean the “ROLL
A SLAT” virtually eliminates evaporation, retains HEAT
in your pool, reduces chemical usage and overall maintenance
is minimized, whilst at the same time is designed for EASY
and SIMPLE operation.
