Roto Glas-Tec offers an extensive range of products and accessories for the safe, correct glazing of windows and doors. Spacer blocking is a small yet crucial factor in the correct installation of glass. As the only connection between the frame and the glass edge, it ensures functionality in the long term and also securely supports the glazing throughout the entire service life of the system. This is reason enough to rely on the highest quality and many years of experience with glazing blocks.

Roto Glas-Tec offers custom solutions for various different frame designs, glass thicknesses and support conditions. From high-quality basic variants to a premium version for heavy or delicate special glass – Roto has the ideal glazing block variant for any challenge, such as glazing blocks with integrated ventilation channel or different profile leg systems. For extremely heavy glass elements, glazing blocks are available with a flexible glass supporting surface and an additional stainless-steel insert.
All glazing blocks are generally stable under continuous pressure, ageing-resistant and temperature-resistant and are compatible with many edge composite sealing compounds used in insulating glass panes.

Accessories

Roto Glas-Tec compensating block

Compensating blocks

Compensating blocks equalise unevenness in the rebate base and therefore form a level supporting surface for the glazing blocks. Compensating blocks also help with ventilating the rebate area and transferring loads.

Roto Glas-Tec glazing tools

Glazing tools

Simple and rapid glass installation with glazing tools for lifting, shifting and moving panes of glass.

Material compatibility

Glazing blocks fulfil their function concealed. However, if they are insufficiently coordinated with the edge composite materials, or are not coordinated at all, this can cause material incompatibility, ultimately resulting in lasting damage to the window. So be proactive and prevent liability-related risks!

Protect yourself as a window manufacturer!

Make use of our unique test service: only Roto offers to test your edge composite materials and laminated safety glass films for compatibility with Roto glazing blocks – so that you can provide safe spacer blocking and ensure that the windows are maintained and work properly for many years to come.
