  QUESTIONS ANSWERS
A. Product : Sliding Stacking System
1
What is the maximum width and height?
  • Sliding Stacking System : Clearview
    • Individual Panel width : 750mm
    • Panel height : 2400mm
    • Opening width : 12m
  • Sliding Stacking System : Paragon
    • Individual Panel width : 900mm
    • Panel height : 3000mm
    • Opening width : 12m
2 What type of glass is used ?  8mm, 10mm and 12 mm (in R&D phase) thickness toughened glass
3 Do your products comply with the National Building Regulations?  Yes. As most of our products are designed around the needs of our Clients and not specifically generic type solutions, we have a Structural Engineer who does a rational design on any non standard application and thus we do not only comply to the NBR, but issue compliance certificates as well when requested.
4
How weather resistant is the sliding stacking system? The Sliding Stacking System has been designed specifically for the South African weather conditions. The system has weather seals all round and a water trough designed to catch any water penetration and channel it outwards. Seals between the glass panels ensure that water and wind does not penetrate the interior. In extreme weather the system might allow slight weather penetration.
5
What does frameless mean – do the systems have frames? The Sliding Stacking System has frames at the sides, top and bottom. This can however be build into the side walls as much as possible to provide the most un-obstructive view compared to any other product. The top track can only be sunk into the top beam by 8mm, thus will always be visible but still give the frameless effect.
6
Can the sliding stacking system be used in commercial applications? Yes. We have enclosed many shops and restaurants in shopping centres throughout South Africa. With the Paragon Sliding Stacking systems we can allow for much higher openings to be closed.
7
Can the system be used as a “smoke room” in restaurants? Yes. Many restaurants need the versatility to enclose certain areas as smoke rooms but also have the advantage of opening the whole area should they need it and still let the clients feel part of the restaurant. The system installed as smoke room on its own has been done in various public areas.
8
If the top beam sags, will the sliding stacking system still work? Depending on the amount of sag, the systems will still operate. The Paragon will allow for 7 mm sag, while the Clearview allows a 3mm sag. However, we recommend that the Paragon system is installed with a compensating channel which will allow a further 15mm sag on a beam when reset.  This is especially applicable on newly build houses and renovations.
9
Can you use double glazing with your sliding stacking system?
No. However, some scrupulous service providers sell the concept of double glazing in their systems. They however mean laminated glass. This does not withstand the wind or impact loads required and should not be used at all.
10
Can the system open both inwards and outwards? Yes. Over the years we have developed the system to allow for all types of configurations.
11
Are the system burglar / intruder proof – how secure is it? Very few places are burglar proof. However, with our high impact safety glass, interlocking panels and wheel combination fixed within the tracks, un-authorised entry is very unlikely. We recommend a passive security system on the inside of the property for such an eventuality. 
12
What tests are carried out on your systems We mainly do impact and pressure tests on our systems. We need to ensure the safe operation in the eventuality of an accident or adverse weather. All testing is done under the auspices of a Professional Structural Engineer. Feel free to view the actual testing on our website.
13
Can the doors be locked? Yes. In addition to an internal locking mechanism which fit into the aluminium section of the system, both top and bottom, you can request additional locks and key locks which can be fitted to the doors.
14
Can any curved design be enclosed? Yes. We accomplish this by making the panel sizes slightly narrower and then angling them around the curve. This provides a curved finish with a fantastic aesthetic effect.
15
Can we enclose with angled sides? Yes. We can accommodate any angle. We have many systems which join at a 90 degree (max) angle. We can also accommodate multi angled sides. Thus fit the system as you desire and to your specific application.
16
How soundproof is the system? As the thinnest glass used is 8mm safety, the noise reduction is dramatic. 70% - 80% noise reduction when comparing to no barrier and further 35% reduction when comparing to steel or wooden windows.
17
Do the systems require maintenance and how often? As the system is made up of various moveable components and weather seals which do deteriorate over time, we suggest a 2 - 3 year service interval on the system. During the service we realign the system to compensate for any sagging which may have occurred over time in the supporting structure. A further 6 months is provided with every service your system receives on the serviced parts.
