THE BENEFITS OF BOTTOM ROLLING

1 VISTAFOLD ALUMINIUM

2 VISTAFOLD ALUMINIUM The Vistafold system is a revolutionary solution for slidingfolding doors developed by the Hillaldam team that has been taking the industry by storm over the last 15 years. The system is a complete departure from traditionally top hung solutions, relying completely on a bottom rolled concept to minimise the requirement for unsightly, costly and often impractical overhead support. Available in both odd and even number panel configurations, it is an easily adaptable system that is highly weather resistant. The Vistafold hardware is manufactured from high quality stainless steel and aluminium components, which are either anodised or powder coated to give an aesthetically pleasing and corrosion resistant finish.

3 THE BENEFITS OF BOTTOM ROLLING There are a number of major benefits to using the Vistafold system and the reasons for making a change away from top hung assemblies is multi-faceted. The Vistafold systems support the weight of the assembly from the bottom up, which requires less bulky overhead support and allows for easier operation especially on higher doors. With the door weight taken up by the bottom track, the perennial problem of sagging lintels is vastly reduced. This in turn all but eliminates the necessity for adjustment over the lifespan of the installation. Any possible deflection of the head opening is accommodated in the channel depth overhead. In cases where some adjustment is preferred however, Hillaldam has an easily adjusted collar-system allowing up to 5mm of movement. Whereas top hung systems traditionally have deep bottom channels that act as dirt and water traps, the relatively slimline Vistafold track is only 8mm deep and easily swept out or vacuumed clean. ADAPTABILITY Whilst many systems on the market require the customer to buy specific profiles, Vistafold allows the use of most standard door and rebate profiles. This eliminates unnecessary expense and avoids having to switch materials between swung, straight sliding and sliding folding systems. Hillaldam feels that all of these features make the Vistafold system unique in its design and operation we hope you feel the same. PANEL SIZING Vistafold is versatile in allowing either an odd number or an even number of panels as well as a choice of offset hinge or standard hinge configurations. The easy calculation sheets make it a simple process to size the doors no matter which option you choose. VISTAFOLD

4 One of the major advantages to the Vistafold system is that it allows both tracks and overhead channels to be completely concealed when the doors are closed. This is a major aesthetic advantage but also assists with eliminating the build-up of dirt in the bottom track. VISTAFOLD

CALCULATIONS - UNEVEN PANEL Where: PW = Panel Width P = No. of Panels OW = Opening Width TF = Thickness of Frame For an opening using sinkless hinges A 4mm gap between panels is allowed for and a 7mm gap between the hinge leaf and the jamb to accommodate the lock. OW = opening width P = no. of panels Panel width (PW) = OW (2xTF) - (Px4) - 7 P For an opening using butt hinges A 8mm gap between panels is allowed for and a 7mm gap between the hinge leaf and the jamb to accommodate the lock. OW = opening width P = no. of panels Panel width (PW) = OW (2xTF) - (Px8) - 7 P NOTE: Cutout in door stile and roller and guide joint: Top edge: 10mm deep x 35mm wide (from edge) Top face: 10mm deep x 7mm wide (from edge) Bottom edge: 42mm high x 33mm wide (from hinge side) Bottom face: 42mm high x 7mm wide (from edge) VISTAFOLD UNEVEN

CALCULATIONS - EVEN PANEL Where: PW = Panel Width OW = Opening Width P = No. of Panels E = No. of End Panels TF = Thickness of Frame 10mm clearance to allow kick of doors For an opening using cranked hinges and all doors of even width: PW = OW (2xTF) (Px4) - 10 P For an opening using Non-cranked hinges where the end door is 12mm longer PW = OW (2xTF) (Px4) 10 (12xE) P Once you have PW for the non-cranked formula, simply add back 12mm to each end panel to determine its width. EG: For a 2-door Vista Duo with non-cranked hinges in an opening of 1750mm PW = 1750 (2x30) (4x2) 10 (12x1) 2 = 1660 = The door hinged to the jamb is then 830 long and the door with the end roller = 842mm. NOTE: Door stiles min 65mm wide All door leaves equal widths Cutout in door for bottom roller: 42mm high x 32mm from hinge in door edge 42mm high x 21mm from hinge in door face Cutout in door for top guide: 9mm high x 32mm from hinge in door edge 9mm high x 21mm from hinge in door face VISTAFOLD EVEN
