Classic, Elegant, Character

The Classic-ISO® profile system is ideal to renovate historical buildings that do not meet today’s technological performance standards while maintaining their authentic character.

Divided Lights - TDL & SDL

There are three ways to divide glass elements into smaller units, which are usually done for aesthetic reasons.

Truly Divided (TDL)

This system divides window units with several smaller glass panels separated by steel profiles. All of MHB's glazing bead systems can be used fitted with this system, including the putty seal below.

Truly Divided Light

Simulated Divided Light

Another solution to divide window units is to place muntins and grilles on both sides of the glass. the appearance is identical to the true divided lights because a spacer is built inside the insulated glass. This solution offers better insulation and for casement windows it increase the stability.

All simulated light solutions have a flat grill welded on one side that makes one element with the frame. The sightline is only 3/4" inches wide.

SDL - EL Tray System

Grille System with an extremely slim appearance. EL Tray is exclusively used in combination with L-shaped glazing beads with visible fixing points.

SDL - T-Shaped Muntin System
