Description

These glass cubes are 20 mm wide, 3, 4 or 5 mm thick and 100 mm long. In order to comply with the installation guidelines (NPR 3577; Nederlandse Praktijk Richtlijn; "eisen voor de beglazing van kozijnen, ramen en deuren in buitengevels"), use this block best with insulating glass of a maximum thickness of 18 mm. 

 

Features of glazing block 20 mm wide:

  • Glazing blocks made of polypropylene
  • Impact resistant, even at low temperatures
  • Universally applicable; ventilating properties of tunnel blocks and the strength of grid blocks
  • Length 100 mm, width 20 mm, thickness of your choice
  • Various widths and thicknesses available (always 100 mm length)
  • See NPR-3577 for correct placement guidelines and use glass cubes

 

These 20 mm wide glazing blocks are supplied:

  • In a net of 100 pieces or a box of 1,000 pieces

 

Points of attention:

  • Use this size block for insulating glass with a maximum thickness of 18 mm
  • Preferably, do not place glazing blocks on top of each other to compensate for a different circumferential clearance, but place 1 cube with the correct thickness. Thinner blocks have less or no drainage channel and that is precisely the purpose of the blocks; ventilating effect and the removal of moisture
  • The glass blocks ensure that insulating glass does not stand directly on the frame. This allows moisture to drain to preserve the sealant of the insulating glass and of course also the frame. Therefore, choose the right blocks and place them in the right way
  • The placement of the glass blocks differs per situation (for example, the glazing of a tilt and turn window is completely different from the glazing of a fixed window). Be well informed to avoid placing the blocks incorrectly. Incorrect placement can lead to damage to the frame and / or glass
