Buying your Rods and Mortar Kit

When buying glass blocks you also need to think about how much of the installation kit you will need for your specific build. This is where our kit calculator come in handy. Just add in the type of glass block you will use, how many high and how many wide and the calculator will tell you what other kit you need to complete the build.

The Rods and Mortar Kit Calculator is recommended for External openings, for an internal project, use our Block Lock Kit Calculator or Pegasus Block Lock Kit Calculator.

Rods and mortar system will calculate the opening with the specified spacer size, if Pegasus, you can achieve a 2, 5 or 10 mm spacer and if Basic, you can achieve a 10 mm spacer only. The Calculator will add everything needed for a wall going into a four sided opening, if your wall is open ended you can remove the expansion foam and you only need ties on the sides that are attached to the wall(s) and ceiling/head.

If you are not sure of what materials you need, or have an opening larger than 15 x 15 blocks, please fill out our Contact Form Submission with all relevant details and we can get back to you as soon as possible. Alternatively you can give us a call on 01243 790425.
