Realization of a glass brick bay: assembly of bricks

Glass bricks are a particularly interesting material for those who want to light a room without making a permanent opening (door or window) in one of its walls. In addition to good lighting, the glass bricks also have excellent sound and heat insulation qualities. Their implementation, after drilling a wall, uses a particular laying technique, which is clearly explained in this sheet.

Necessary material

  • pegs
  • Bubble level
  • Trowel
  • Float
  • Joint iron
  • Sponge
  • Hammer

Steps

  1. Laying the plate and cleats
  2. Assembly of the bay
  3. Realization of lap joints
  4. Formwork of the amounts
  5. Joint finishes

Laying the plate and cleats

Chipboard

1. An agglomerate board (particle board) will serve as support for the glass bricks during the construction of the bay. It is maintained from the outside with pegs.

2. Before starting to place the tasseax, it is essential to check the verticality of the plate. You will place on the support and on the uprights, polystyrene strips that will serve as joints of independence between the glass blocks and the masonry (resilient strips). They are lined inside an asphalt strip.

3. Glass bricks must never be joined. Fir cleats, placed horizontally and vertically, will ensure a correct space (1 to 2 cm) as well as very regular joints.

4. Place a base of bastard mortar (1 part of cement, 1 part of slaked lime and 4 parts of river sand, all mixed with very little water), put in place the vertical irons, then the glass bricks.

5. Between each row of glass bricks, place two fir tree spacers (use planed bar). Also put in place the horizontal irons.

6. With the bay completely assembled, place the polystyrene strip, which must be equal to the thickness of the bricks. It will constitute the superior independence seal.

7. The gap between the top edge of the glass blocks and the polystyrene strip is filled with mortar so as to seal.

8. A mortar cover joint will form a rebate on either side of the bay. This rabbet will have at least 50 mm for the uprights, 60 mm for the high part and 35 mm for the support.

Formwork of the amounts

9. The realization of the lap joints used to form the rabbets also requires the manufacture of small forms.

10. The mortar is trowelled at the top of the stud formwork. Make a formwork at the level of the support. Check horizontality at the bubble level.

12. The spacer blocks have been removed. You can proceed to the realization of the joints. Use for this a joint iron.

13. A perfect finish of the joints is done with a slightly damp sponge before complete drying of the mortar.
