heritage installation guide
Glazing of Heritage Sealed Units® manufactured by JCL Glass Ltd should always be carried out in accordance with the principles and recommendations of the Glass & Glazing federation. When glazing it is important to prevent the ingress of water into any rebate to retain the integrity of the seal. Do NOT use linseed oil putties or butyl glazing compounds that comes into contact with the units' edge seal when installing Heritage Sealed Units®.
recommended max unit sizes
Note: Due to potential glass deflection with narrow unit cavities; effective maximums will also vary with different cavity fills.
All surfaces must be clean, dry and free from frost, grease and loose materials. Apply primer if required. In situations where an especially neat finish is required, use masking tape to cover the face edges of the joint and remove immediately once tooling has been completed.
