EXTE ELITE XT - A RANGE OF FASCINATING POSSIBILITIES
EXTE has been designing roller shutter systems for several decades. Its consistent development and refinement of its system concept and platform technology is always in line with changing market demands. The new EXTE ELITE XT means all types and models can now be realised with only one system platform. This opens up new business and sales opportunities, e.g. by use of the venetian blind and external maintenance opening in the cap box.
TECHNICAL INNOVATIONS FOR MAXIMUM ADDED VALUE
Many years of development have gone into the new EXTE ELITE XT roller shutter system. The most prominent result is the concept of variable opening downward, to the back and outside and use with venetian blind. Another fascinating aspect of this solution is its simplicity: its capacity for hanging is the same for all types of openings, irrespective of the type of maintenance opening being used. It makes no difference whether an insect protection element is in use or not. This gives EXTE customers a major advantage in the market. The entirely new concept of drive bearing, the variable guide rail, the easy-to-assemble solutions for connecting, division and modified inlet and the cassette concept for insect protection in windows and doors also represent major advantages. EXTE ELITE XT brings to the market for the first time a pioneering roller shutter system allowing maximum flexibility.
MAXIMUM FLEXIBILITY, MINIMUM NUMBER OF PARTS. ONE ASSEMBLY SET, FOUR OPENING TYPES
The new EXTE ELITE XT roller shutter system introduces a new era in roller shutter design: one assembly set, one side wall, one insulation and one fastening shaft – and four types of maintenance openings. This is all based on the design principle that one element should be usable in different ways in a range of different situations. The type of opening can be changed in the side wall simply by changing the inlet. The base board slides into a new position in the head piece. The lower maintenance strip is simply shortened at the specified points or, after selection, ordered directly from EXTE.
REDUCED STORAGE REQUIREMENTS
The fastening shaft can be bent simply at two points and thus used for every opening type. This reduces not only maintenance requirements but also simplifies ordering of supplies. The installer can choose between a bent shaft (screw fastening at front on window frame) and a straight shaft (screw fastening on side of the window frame). The shafts fit all window systems. The insulation can also be ideally and quickly adjusted to different opening requirements by means of specially market grooves. The EXTE ELITE XT roller shutter system therefore has the smallest possible number of parts.
MAINTENANCE OPENING ON INSIDE - THE CLASSIC SOLUTION FOR RENOVATION
With its platform principle, the EXTE ELITE XT roller shutter system offers the perfect solution for every situation. In the classic design as cap box for renovation, the inner cover is opened. This provides the largest possible maintenance opening. The aluminium cassette with insect protection is either already installed or can be added very simply as required.
MAINTENANCE OPENING UNDERNEATH THE IDEAL SOLUTION FOR NEW BUILDINGS
The EXTE ELITE XT is also ideal as cap box in new buildings, as the maintenance opening underneath allows this perfect solution, which in turn allows perfect plaster concealment. The inner cover can in this way be provided with plaster brackets and plastered over. Window frame depths up to 92 mm are possible, with the maintenance opening remaining at 100 mm. This is perfectly adequate for all assembly and dismantling work that can arise. The system offers several plaster base brackets made of aluminium and plastic and special screw-in anchors. With the maintenance opening underneath, the upper insulation wedge is held in position in a groove and cannot fall out when the maintenance cover is opened. This facilitates work at the installation location.
MAINTENANCE OPENING OUTSIDE - THE SOLUTION FOR MAXIMUM AIR TIGHTNESS
Whenever maximum air tightness is required in passive houses or public building, the EXTE ELITE XT roller shutter system also offers the ideal solution with the maintenance opening outside version. This is achieved by a simple shifting of the base element. This allows the box to be fully plastered in the interior and sealed airtight. If no insect protection is required, the opening is closed by a streamlined, screwed-on opening cover made of aluminium. The guide channel for venetian blinds and opening on the outside consists of two sections. This allows the guide channel to be plastered while at the same time allowing the system to be dismantled. For divided elements, the standard guide channels are brought to the required dimensions with a doubling section.
VENETIAN BLINDS - MODERN INSTALLATION FOR ATTRACTIVE WINDOWS
With the EXTE ELITE XT, the width of the external maintenance opening can be increased further by moving the base section inward. This provides the easily realisable option of installing a venetian blind. Venetian blind instillations are highly popular as sunlight screens and as adjustable privacy and view protection for use in schools, public or commercial buildings. They are attractive and also available in large widths. For this design, EXTE offers a special mounting bracket for the system, which gives the box increases stability and completely bears the load of the venetian blind. The venetian blind packet can in this way be linked directly to the construction element.
ASSEMBLY PROVIDING SPECIFIC ADVANTAGES LESS IS MORE
The extremely tough drive bearing consists of a bearing washer with universal oblong holes. This allows assembly of every conventional motor. The bearing washer is fixed by means of a corresponding receptor in the side wall. It can be turned in stages of 12° in order to fix the ideal position of the adjustment screws in the motor. By means of a latch (shown in red in the illustration), the bearing washer is fixed in the side wall. The decisive advantage here is that there is now no need for the metal motor bearing. In addition to the reduction in parts and costs by replacing the metal bearing with a plastic bearing, the drive bearing also provides another advantage in dismantling: when the latch is released the entire blind can be rolled down, even if the motor is defect.
SIMPLE, QUICK AND INNOVATIVE
The division wall are screwed into the box. Special insets are available for couplings or separators. One special feature of this solution is that the rotating insets can be inserted completely through the division wall as in a bayonet fitting. The resulting aperture in the division wall is then large enough for a 60 shaft, which greatly facilitates dismantling, in particular with a projecting box and moved inlet. This high quality solution with a moved inlet provides for a complete separator bearing with two-piece covering. This completely avoids any "latching" of the protective shell. Assembly and dismantling are also greatly facilitated by the two-piece covering.
INTEGRATED INSECT PROTECTION - CONVINCING SOLUTION WITH HIGH COMFORT
The insect protection is located in the EXTE ELITE XT between the protective shell and the window. This means the capacity of the roller shutter is independent of the presence of insect protection. This applies to all opening types (insect protection with venetian blind not possible). The screen is positioned in a stable aluminium cassette together with the spring mechanism. This allows insect protection to be prepared independent of the box. The cassette is simply latched in between the inlets in the box. With boxes with maintenance opening inside, underneath and outside, the window insect protection can be subsequently added at any time up to an element height of 2.550 mm including box. The whole operation is quick and easy. The guide channels of the shutter slat are specially prepared for this purpose. Once a cover has been removed, you only need to insert an aluminium section.
INSECT PROTECTIONSYSTEM - ALL VARIATIONS POSSIBLE
The insect protection system can be operated both from the top down as a "window version" and with lateral extraction as "door version". Both versions are possible in one box.
- 1.Simplest operability of insect protection located between shutter slat and window
- 2.Two-piece window with vertical insect protection.
- 3.Two-piece French-door with vertical pull-outs.
- 4.Mounting element with horizontal and vertical pull-out for insect protection in one box.

EFFICIENT HEAT INSULATION - ENERGY SAVING NOW SIMPLE
The legal basis for the stipulations regarding heat insulation in roller shutter systems is clearly defined. These stipulations can be found, at the Federal (German) level, in the Energy Saving Ordinance (EnEV) and, at the state level, the Bauregellisten (building rules lists). When used in a new building, the roller shutter is considered part of the outer wall. Proof of equivalence to the installation examples provided in supplementary sheet 2 to DIN 4108 is required. This allows the architect to work with the reduced ther-mal bridge loss coefficient. When used in an old building, the roller shutter is considered an extension of the upper window frame and is added to a surface section to form a window element. The minimum requirement regarding heat insulation is USB ≤ 0,85 [W/m2K] und fRsi ≥ 0,70. EXTE ELITE XT has achieved the values shown below:
Maintenance opening below/inside
0,83 – 0,74
Maintenance opening outside
0,82 – 0,67
0,72 – 0,73
* USB value in W/m2K; calculation according to draft for EnEV 2012
All necessary proof and test certificates have been received by EXTE. They can be presented for inspection on request.
ROLLER SHUTTER BOXES AND HEAT INSULATION
The German Energy Saving Ordinance (EnEV) represents the legal basis for heat insulation in roller shutter boxes. A distinction is made here between: New buildings – the roller shutter box is a fixed element in the outer wall. Old buildings – the roller shutter box is visible and becomes a component of the window.
