Completeness and warranty

Completeness of the facade system depends on the specific type of VFS as per TU U B.2.6-24.3-35965995-001:2016.

The system generally consists of brackets with thermal insulation gaskets attached to the building walls, load-bearing frame or inter-floor slab; vertical and horizontal sections that adjust the air pathway width and offset distance of the entire system; and facade tiles that perform aesthetic and protective functions.

A batch shall be packed in the original packaging, which protects the products against mechanical damage and precipitation during transportation and storage, except for technical documentation that may be wrapped in paper according to DSTU 2191 (GOST 16295).

Warranty period of storage at end user’s store is specified in the accompanying documentation and starts from the date of shipment of products (provided the requirements of Section 5 of the Technical Specifications are met).

SCANROC, the manufacturer of materials and components used in VFS, and the mounting contractor of this system guarantee compliance of the system with the requirements of technical specifications provided that transportation, storage, installation, and operation conditions are met.

Warranty period for the system makes at least 7 years from the date of commissioning, provided that the consumer complies with the system’s operating rules.

Recommendations on storage

Storage, loading, and unloading of products shall ensure their safety from mechanical damage, moisture, and chemically reactive substances. Products shall be stored in a dedicated storage area and be kept on clean surfaces or in their original packaging and protected from weather effects.

SCANROC facade system Maintenance and Operation Instruction Manual

To ensure comfortable indoor climate at any time of the year, care shall be taken to ensure that the thermal insulation layer remains dry. To ensure reliable and efficient operation of the facade thermal insulation as well as fulfillment of the manufacturer’s warranty obligations, the building’s spouting chutes and drain pipes shall be monitored for serviceability. Water must not leak onto the thermal insulation layer. Any damaged tiles on the facade plane shall be replaced promptly.

If necessary, the face layer surface can be manually brushed, avoiding contact of the thermal insulation layer with water.

Routine inspections of the ventilated curtain wall system frame, fastening elements and facade tiles shall be performed throughout the entire operating period every 4 years. The building owner shall carry out inspection and, if necessary, SCANROC technical specialists or their regional representatives may be involved. SCANROC will monitor the performance criteria of the facade system throughout the warranty period. During the process of monitoring, the facade tile appearance is inspected for wear and tear, and any cracks or chips; air duct width is measured; and the ventilated curtain facade frame is checked for any corrosion or other deterioration signs.

It is STRICTLY FORBIDDEN to attach any parts or devices directly to the facade tile or attachment frame of a ventilated facade during construction and operation, except where agreed and approved by SCANROC representatives.

Installation and replacement rules for facade tiles

SCANROC facade system has excellent anti-vandal properties, which is confirmed by SCANROC tile fracture tests. This guarantees the longest and most comfortable operation of the system. However, the advantages of a curtain-type ventilated facade do not end there: even if the facade tiles have been damaged, they are easy to replace, regardless of whether they are a single tile or a group of tiles. You can always purchase the necessary quantity of SCANROC facade tiles to replace the damaged areas (please contact SCANROC managers, specify the tile color number or send a photo of a damaged facade). Also, it is practical if you save the remains of entire tiles for possible repair.

Figure 2. Upper row of damaged tiles dismantled

Figure 3. Bend back the adjustment tongues and raise the tile gently

SCANROC facade tiles are hinged on three adjacent racks using special curved cut-outs on the racks and remain fixed with adjustment tongues. Replace facade tiles stepwise:

Step 1. Break and pull out the top row of damaged tiles (Fig. 2)

Step 2. Bend back adjustment tongues on the racks (Fig. 2, 3)

Step 3. Raise and pull up the lower damaged tiles to release them (Fig. 3, 4)

Step 4. Disassemble the damaged wall section from top downward (Fig. 5)

Step 5. Replace damaged tiles with new ones from the bottom row to the top row, securing them with adjustment tongues.

IMPORTANT! Keep construction and other debris out of the ventilation space, otherwise performance of the ventilated curtain facade will be decreased.

Installation of external facade elements

When installing any external elements on a previously installed facade, never attach them to the facade tiles or frame of a curtain-type ventilated facade. Attachment elements (anchors, brackets, angle brackets) of air-conditioning units, satellite dishes, drainpipes, advertising banners, decorative fences and boxes, other devices, mechanisms or parts shall be brought under a layer of insulation, providing additional insulation from the building wall. Let’s consider the installation procedure for the outer air conditioner unit as an example (other external elements shall be mounted similarly).

  1. First of all, carefully read the installation instructions for the split-system air conditioner.
  2. Remove facade tiles from the installation area, and then remove the racks and ledgers that interfere with the installation of the air conditioning unit brackets (we recommend relocating attachment points for the air conditioning unit brackets, if possible). Note: NEVER use an angle grinder to dismantle the frame of a curtain-type ventilated facade or to cut individual frame elements.
  3. Remove the insulation layer carefully and, if necessary, remove the angle brackets.
  4. Mark the attachment points for the air conditioning brackets and the air conditioning tube outlet.
  5. Install brackets for the outdoor air conditioner unit following instructions of the split-system manufacturer.

IMPORTANT! Split system brackets shall be insulated from the wall by thermal pads min. 2 mm thick made of foamed PVC or other chemically neutral materials with a thermal conductivity factor λ not exceeding 0.06 W/(m⋅K) to avoid cold bridges. Use plastic dowels for fastening where possible. The air-conditioning tube shall also be fitted with a thermal insulation jacket meeting the above conditions.

  1. Fit removed angle brackets and ledgers in place.
  2. Fit the insulation and secure it with disk-shaped dowels.
  3. Fit removed racks in place and install the auxiliary racks required at the points where the air conditioner brackets extend outwards the facade.
  4. Install facade tiles. At the outlet of the brackets and tubes, the tiles are cut vertically along the width of the bracket (tube) and installed so that each tile is placed over 3 adjacent racks. Is not recommended to cut tiles lengthwise, and it is STRICTLY PROHIBITED to cut off or drill tile teeth.

Installation flow charts for air-conditioning units, drainpipes and satellite antenna brackets are given on pages 12-16 of the Maintenance and Operation Instruction Manual (see below).
