Glass partition joints by Smiths Building Systems

Introducing I-Line®

Our I-Line system is a dry joint range with flush fitting, which creates a sleek, elegant and seamless finish when utilised in glass partition wall construction.


Available in clear glass and also black finish on request, our products are completely recyclable. I-Line finds use in both single and double glazed partition walling systems for straight runs of glass. The product range covers several jointing types, including 2-way, 3-way, abutment and infill joints.



Expandable Dry Joints

As part of our I-line range of products we have an expandable I-line glazing joint in the form of the Opti-Joint for 180° 2-Way Joint. This joint allows for the quick installation of glass in various sizes ranging from 17.5mm to 25mm.



Minimalistic Look

The finishing aspect of a glass partition wall is essential - an obtrusive jointing product could potentially spoil the look and feel of the installation. The I-LineĀ® design completely resolves this problem because not only does the joint fit flush with the glass, as the product is transparent, it is barely noticeable. I-Line has numerous uses in any glass to glass applications.
