Research and Development: counterframe for retractable doors


Our technical staff are always searching for those small details, that extra imperceptible quid that can create a gulf between ourselves and others, the concrete structural features of products, but they go beyond this to involve the laying phase, masonry and the assembly of various accessories.




The panels do not have the common vertical folds, but horizontal,more suitable to make the entire structure more solid and robust without annoying swelling of the internal chamber of the counterframe. That is, a sort of “tinned” effect is created.

2: The electrowelded mesh is not welded, nor crimped to the panel, but staplet with a small tolerance for movement. This tolerance (in case of natural settling of the masonry wall) keeps the central structure from suffering any damage. In fact, the only element in direct contact with the cement mortar is the electrowelded mesh. The electrowelded mesh (present only in the plaster version) is created with longitudinal and transverse wires 2 mm in diameter. The mesh sheet has no edge closing wires: the ends are formed by “free points” that can move and better align with key points and contact areas on the wall.

3: Wooden riser: laying is greatly facilitated by the lateral clamps that are sunk in the cement mortar. Installation of the door is easier because the carpenter con utilise his normal screws.

4: Extractable lower clamps: these are placed under the counterframe and are excellent for anchorage and alignment with the pavement. They can be sunk into the cement or screwed into the pavement.

5: Rear plug: there is a cavity and lateral tabs which allow easier insertion of the hollow block and the mortar cement and consequently greater anchorage of the counterframe to the masonry wall for its entire height.

6: Upper Headboard: the upper headboard has a smoth edge which is useful to more easily smooth the plaster.

7: Lateral clamps: these are positioned on the wooden risers and the rear plug of the counterframe and sunk in cement mortar for more secure anchoring.

8: Spacers are used during laying and serve to maintain the same height for the entire counterframe.

9: Door brush seal riser: the profile is an integral part of the counterframe and extends for the entire height, thereby avoinding any separation of the brush seal with respect to the door. In pratical terms, this translates into a significant reduction of dust formation inside the counterframe.

10: Completely extractable track: made from aluminium extrudate, this component is completely removable from the counterframe. Any post-masonry intervetion is therefore possible from inside without ruining the walls.

11: Roller: 4 sliding bearings (one inside each wheel), steel shaft and nylon wheels. The door slides silenty without any friction. This is due to the balls (not needles) present in the bearings and to the very nature of accessory materials in the sliding kit. It is rated at 120kg, excellent for the vast majority of doors.

12: Self-centring door guide: included in the assembly kit. It makes it possible to mount and centre the sliding door just a few steps. The installer thus has only to focus on fitting the slot in the base of the sliding door into the door guide, which was previously fixed flush with the floor. With no extra additional measurements, the same door guide determines the centre of the lodging for the counterframe. There is a single mould for all thicknesses (125/105/100/90 mm): the preformed borders must simply be removed depending on the required size.
