I don't know how to decide for a swimming pool: interior or
A: All things have their advantages and disadvantages.
The interior swimming pool permits to swim in all comfort in
winter. The maintenance cost of an interior swimming pool is
on the other hand exorbitant. It is necessary to continue also
to heat the swimming pool in summer. With an outside swimming
pool, one cannot swim in winter, on the other hand in summer:
what a delight (as far as the weather is fine). The disadvantage
of an outside swimming pool is the cleaning.
With a ROLAL® enclosure, you combine the two solutions.
Not only you can swim all year round in all comfort, but the
costs of use are strongly reduced (cleaning also) and in summer
your water of the swimming pool heats for free thanks to the
solar radiance. On a clear day you then open your enclosure
and thus can swim into the open air.
Q: What does an enclosure cost?
A: It depends on the dimension of the enclosure. To give
a price per m² is not possible, since an 8 m long enclosure
is also equipped with one front and one rear gable like a 20
m long enclosure, to make the plans for an 8 or 20 m enclosure
is the same thing, to place the orders doesn't change anything
and for the transportation we must drive as far.
It also depends on the model, low enclosure, mid-top, high,
with or without beam,...
A price is volatile, quality remains.
Q: When is it necessary to pay and how much?
A: We ask for a deposit of € 2.500 with the order.
The balance of € 2.500 is payable after installation. The
difference is payable at delivery.
We are no company asking for a 30 or 40% deposit (which represents
a fair amount of money) to declare bankruptcy the day after,
as some other companies do.
Q: What pavement do I need?
A: Tiled preferably. The auto-block pavements (clinkers)
are to avoid, except if they are flowed in the concrete.
Q: What foundations do I need?
A: Minimum 15 cm of reinforced concrete with a lattice
Q: At what moment will the enclosure be placed?
A: At the end of the works, when the terrace is tiled
Q: What does an enclosure weigh?
A: For a normal type enclosure (without beam), an 8 m
wide section weighs about 340 kg. One 8 m wide front, weighs
about 700 kg. For a beam enclosure, a 4 m wide section, weighs
about 170 kg. A 13 m long beam weighs about 800 kg, one of 15
m about 1100 kg and one of 17 m about 1400 kg.
Q: What does one fit as glazing in the enclosure around?
A: Preferably 6 mm glass, because the glass is inert
(doesn't warp) and remains aesthetic with the passing of the
years. A glass glazed enclosure still looks new after several
years, whereas a Plexiglas glazed enclosure appears decrepit
after some months. The Plexiglas also scratches itself as
soon as one touches it. An airline will serve drinks in plastic
goblets in economy class whereas in" business or first"
they serve you drinks in glasses!
Q: What does one fit as glazing in the roof sections?
A: The 16 mm triple thickness "no drop" polycarbonate.
The "no drop" process consists in a silicone film
applied during extrusion on the lower surface avoiding the
formation of water drops in case of condensation.
Q: Don't the children risk breaking a glass?
A: The 6 mm thick glass is not more dangerous than
Plexiglas. Are the windows of your house also in Plexiglas?
Double-glazing is no stronger, as usually double-glazing consists
of 2 sheets of each 4 mm only. We use 6 mm.
Q: What is the difference between an enclosure with and
A: An enclosure with beam not only gives a greater
rigidity and resistance to snow and wind loads, it also permits
to open the enclosure all alone. One doesn't need a motorization
that can be jammed after 6 or 7 months of inactivity. An enclosure
with beam can be also opened according to the direction of
wind. If wind comes from the right, you open the left side
or vice versa.
Q: Is the enclosure mounted on wheels?
A: Naturally, otherwise it would not be telescopic.
Q: Is there a rail on the floor?
A: Preferably yes, if you want to be able to open and
to close the enclosure every day. The use of the rail also
increases the mechanical resistance of the enclosure to the
wind and snow loads.
Q: A rail, does that mean that I have to oil or grease
A: Certainly not. Our auto-lubricant wheels don't require
any maintenance and especially not oil nor grease. Because
of the absence of these two substances, no dirt can remain
glued in or on the rail.
Q: Can I buy an enclosure in black?
A: You can buy an enclosure in any colour according
to the RAL palette without extra charge. We ask on the other
hand for a supplement for the red with yellow peas or the
Lila striped pink.
Q: How many doors are there in an enclosure?
A: Standard, an enclosure is equipped with 2 sliding
doors, one in the front gable, one in the rear gable. It is
however possible to fit several doors, according to the width
of the enclosure, in return for extra charge.
Q: Can I have a lateral access?
A: It is also possible on demand, and in return for
Q: Can the doors be locked?
A: Every door is equipped with a child lock, permitting
to forbid the access to children. The sliding sections are
also blocked from the inside by a simple sliding latch.
Q: Can the children open the enclosure?
A: Yes, as far as they have the key. Thanks to our
system of auto-lubricant wheels, the sliding of the different
sections is an easy thing, especially if there are rails on
Q: I live close to a farm, what about flies or insects?
A: We place sliding fly screens, without extra charge,
with every door which permits to ventilate the enclosure without
having the intrusion of thousands of flies.
Q: Am I going to be able to stand up in my enclosure?
A: As all our enclosures are constructed to order,
we can guarantee you a height of... cm according to your desire
Q: Must I bolt down my enclosure to the floor after every
A: Never, except the Atlas model where all sections
fold back to one side.
Q: Do I have to clear the snow of the enclosure in case
A: No, this thanks to the use of the rails but also
because of the rigidity of the construction (aluminium / stainless
Q: What about electrolysis between two different metals?
A: We isolate the two metals by means of a silicone
coat during assembly. To have the electrolysis, a catalyst
is necessary. We don't supply this.
Q: Is there a guarantee?
A: No, there are two of them. The first is an all round
guarantee of 10 years on parts, labour and travel expenses.
You are therefore sure that your ROLAL® enclosure won't
cost you a penny for the first 10 years.
The second guarantee is of 25 years (from the date of installation)
on the metallic structure against storm winds until 150 km/h
and snow pressure up to 120 kg/m².
Q: How am I going to maintain my enclosure?
A: By means of a high-pressure jet cleaner.
Q: I need to buy a new robot to sweep the swimming pool;
do I have to buy it?
A: Do so if you please, but to our opinion it doesn't
justify itself anymore. You will use the manual vacuum cleaner
between 3 and 4 times a year.
Q: What is the temperature in an enclosure like?
A: One can compare the temperature in the enclosure
to the temperature in your car being parked at the same place.
Even the brightness heats the inside of the enclosure (and
therefore also the water).
Q: What is the temperature of the water like, with an enclosure?
A: In the beginning of the season you will see the
temperature of the water increasing by + / - 2° C per
A water temperature of 28° C is quite normal with an enclosure,
even when the weather is not pleasant.
Q: Can I swim in winter time?
A: Certainly, but it is nevertheless more pleasant
heating the water a little.
Q: What is the energy consumption to heat the swimming
pool in winter?
A: To maintain the swimming pool at 28° C all winter
long, we consume according to the roughness of the winter
between 2.000 and 3.000 litres of fuel per winter.
Q: Is it necessary to heat the air?
A: Not necessarily. The water of the swimming pool
does this by radiation (principle of the radiator).
Q: Is there condensation?
A: If one doesn't cover the water and that the temperature
of the water is higher than the air temperature, there will
Q: Do I need a floating cover?
A: It permits to avoid a maximum of water evaporation
therefore of condensation. The evaporation of water in winter
can be such that you believe to have a leak in the swimming
pool. It is therefore better to keep the floating cover. It
will also allow you to space cleanings of the enclosure inside.
Q: Where can I see an enclosure?
A: At our old place after taking an appointment. Ours
has been constructed in 1993. It will allow you to see how
an enclosure ages.
Q: Are there closing times for the office?
A: Yes, from 10 PM until 6 AM. We are even at your
service on weekends and holidays. It is sufficient to phone
to make an appointment.
Q: Can the enclosure be attached to my house?
A: Yes, as far as the swimming pool is not located
50 m off the house. One can connect on one gable (economy
of one gable) or laterally.
Q: Can the enclosure be independent of the house?
A: Certainly. The first enclosures have been conceived
in this sense.
Q: Can I slide back the enclosure to only one side and
how long does it take?
A: With an enclosure folding back to only one side,
it is necessary to detach the front gable first, before you
can slide the sections towards the back. It takes + / - 10
minutes either way. We also can (for the small enclosures)
fit a tilting front. This one has the disadvantage, that if
you want to open a part of the enclosure only, the gable will
hang right in the middle of the beach and will forbid the
access to the rear part and as well hang continuously over
Q: Do I need as much time with an enclosure with central
opening or with beam?
A: No, in this case, it is sufficient to slide the
sections toward their respective side merely. Time: less than
two minutes, as well for the opening as for closing.
Q: Can I open and close again my enclosure every day?
A: Certainly with a Diabolo enclosure opening from
the centre or with a Rhodos or Titan beam enclosure.
Q: Are gutters fitted on the enclosure?
A: No, it is impossible since the sections slide one
under another. If the terrace is not tiled yet, or that it
must be modified, it is worth to foresee a slope toward the
outside, up to 2 cm per meter.
Q: What about after-sales service?
A: We are proud to say that we don't have an after-sales
service. If nevertheless something has to happen, either the
boss or the installation team will be at your home within
Q: How is an enclosure constructed?
A: Manually. Every enclosure takes about 2 days of
manufacturing and 3 to 4 days of installation on site.
The same team does all this work from A to Z, which guarantees
that a staff's member won't be able to reject the responsibility
on another member, in case of error.
Q: Are there standard measures?
A: Since the invention of the computers, there are
no standard measures anymore. Before, making up the drawings,
took a whole day, this is now done in a flat 10 minutes.
Q: Is the polycarbonate resistant to hailstones?
A: We keep a hammer and a sample of polycarbonate at
your disposition for more thorough tests.
Q: How about the tightness between the different sliding
A: This is done by means of a brush in polypropylene
trapped in a stainless steel holder.
Q: Can leaves and bugs enter underneath?
A: No, this thanks to our rail on the floor. Below
the bottom profile, we fit a flexible PVC gasket that pushes
on the rail and makes the tightness thus on the whole length.
Q: Do you have dealers or representatives?
A: No, this guarantees you to have the best Manufacturer/Customer
price, without intermediaries You will only have one person
to talk to - the boss.
Q: What is the delivery time?
A: It depends on the season and the demand. In low
season delivery takes about 3 weeks, in high season, it can
go up to 6 months.
Q: Is there an auspicious period to order an enclosure?
A: It is a fact that as the winter is the low season
for us, we will have more time to dedicate to you. It will
also allow you us to be ready on time for the next season.
Is the date of delivery respected?
A: Except cataclysm or natural disaster we deliver
always at the date indicated on the order form.
Q: Do you also have "limited series?"
A: No, it is a trap that some competitors use. If an
automobile manufacturer makes a limited series of 2.500 vehicles
on a production of 100.000 vehicles/year, this is normal.
We manufacture + / - 100 enclosures per year, and cannot offer
limited series therefore. Our volume of manufacture is limited.
Q: Can one reach you otherwise than by telephone or mail?
A: Yes, by fax at n° +/352/184.108.40.206 or on the
Internet on our http://www.rolal.com site or by electronic
mail at our firstname.lastname@example.org address
Q: Is the price fixed until delivery?
A: All orders will be honoured at the ordered price
as far as the delivery intervenes within 365 days of the signature
of the order. It allows you to order your enclosure at the
cost of this year and have it installed next year.
Q: Will I regret my purchase?
A: Yes, not to have ordered your enclosure earlier.
Q: Can you come to my place and put up an enclosure in
my garden to see how it presents itself?
A: Alas, we don't have the time for this, especially
as the colour won't be the one that you would have chosen
and that the dimension certainly won't fit.
Q: Do you come over to make up a price?
A: Certainly, and this without engagement of your part.
Q: Do you have an ISO 9002 certificate?
A: Certainly not, we don't need certificates to respect
our deliveries and engagements. An ISO 9002 certificate only
verifies the fact that the administrative part is well done.
Selling you shit or quality won't change anything. That your
customers have the worst technical problems afterwards, doesn't
influence on the certificate. We therefore prefer to sell
quality without ulterior problems.
Q: Now that I finally have a price, don't you think this
is too expensive?
A: People spent as much or even more money to buy a
car, which will only last 5 or 6 years. Our enclosure, is
a lifetime purchase.
As my grandmother also said : "I'm not rich enough to
buy second hand or cheap equipment". You have a 25-year
guarantee on the enclosure !
Q: Are you also n° 1 in the world ?
A: Anybody can claim to be n° 1 of his country
or the world. Nobody can check this. How can a company possibly
know that it would be n° 1 ? Just bear in mind that people
using this argument, have often nothing more to offer.
Q: Can I choose myself the profile I prefer ?
A: We don't propose 2 or 3 different profiles at different
prices. This, will only make you choose for the cheapest.
On the opposite, the day your enclosure will collapse, you
won't be able to claim on the supplier as YOU will have choosen
the profile and not the supplier.
Studies on resistance have been done (or should have) and
this leaves you no choice but the best. It is the manufacturers'
responsibility to offer you what is needed.Manufacturers using
this strategy only look to sell, AT ANY PRICE, and f
the customer. This deplorable mentality shouldn't exist.
Q: Can I again ask other questions?
A: We like customers asking questions. Therefore, if
you find some, it will be a pleasure for us to supply you
with an answer.
