TRADITIONAL LAYING

Recommendations for laying glass blocks

Warranty

Bormioli Rocco s.a. declares that the technical, dimensional and aesthetic parameters of the glass blocks it manufacturers conform to the industry regulations governing each characteristic:
EN 572-1 Composition of the glass
EN 1051-1 Shape and dimensional tolerance specifications
EN 1051-2  Conformity and requirements
CE Marking of product
Moreover, since Bormioli Rocco s.a. has no control over the quality of the installation and accessory materials used, no warranty can be provided once the glass blocks have been installed.

Operations prior to laying

Check the dimensions of the wall, height and width.
Establish the distance between the blocks and the distance between the first block and the side walls.
Establish the number of blocks.
Establish the number of spacers.
Establish the length of the expansion joint to be positioned at the base of the wall, at the top and sides.
Establish the number of steel rods and their length.
Establish the amount of special mortar for glass blocks required (take care to check the “use-by” date).
Check that the glass blocks are undamaged and that the product complies with the requirements defined.
Mark out the wall horizontally and vertically with a laser scanner or similar.
Check perpendicularity between the floor and side walls (fig.1).
Position the first row of blocks without mortar. Check the number of blocks required and the distance between them by inserting the spacers.
Check the distance between the first block and the side walls.
Mark the positions of the steel rods on the wall, then drill the wall to allow the rods to penetrate slightly into it.

Laying operations

Lay the expansion joint on the floor, along the vertical walls and ceiling.
Create a base with the mortar, possibly the same height as the skirting (if present) (fig.2).
Start laying the first row of blocks. Apply mortar to both the top of each block and on the side touching the next block. The distance is established by the plastic spacers used.
Apply mortar between all the gaps between blocks.
Set the horizontal steel rods in position against the plastic spacers. The rods should penetrate slightly into the vertical wall through the previously drilled holes. (fig.3)
Lay the second row of blocks in the same way as the first (fig. 4).
Insert vertical steel rods between the blocks but make sure that they never touch the glass. Always make sure that the steel rods never touch the blocks.
As block laying proceeds, check to make sure that the wall is perfectly vertical.
Repeat the procedure until the wall has been completed.

Finish

Check that the mortar has set, then gradually remove the excess from both sides before it hardens completely.
Remove the ends from the spacers, taking care not to damage the blocks.
To finish, spread a layer or mortar over the gaps with a soft trowel.
Clean the surfaces with a sponge soaked in water.
Dry the surfaces (fig.5).

NOTE
Do not use abrasive materials, oily-based chemical products or acid-based products for cleaning purposes, with special attention to fluorides.
