GLAZING MAINTENANCE RECOMMENDATIONS
To obtain maximum life expectancy for sealed units, it is essential that water is prevented from leaking round the glazing putty / gasket into the frame and lodging there. Glazing and maintenance recommendations must therefore be carried out in accordance with the unit maker’s instructions. The schedules of maintenance detailed below refer to commonly used and accepted glazing systems are approved by the Glass and Glazing Federation for houses and low rise buildings. Where other systems have been used the unit maker should be consulted for advice on maintenance. Glazing should be inspected at least annually and treated as necessary.
REMEMBER, MAINTENANCE IS THE RESPONSIBILITY OF THE OWNER / OCCUPIER AND FAILURE TO COMPLY COULD INVALIDATE THE WARRANTY.
- Standard units fitted into wooden frames with beads, using non-setting glazing compound and silicone sealant: Where they are surface cracks, loss of adhesion or voids, rake or remove the faulty compound or sealant and replace with a non-setting compound or silicone sealant, preferably the same as originally used. Always use non-setting glazing compound for back bedding repair purposes. When pointing non-setting glazing compound between the beads and glass ensure that, the compound slopes away from the glass. When using silicone sealant ensure that the sealant is proud of the glass, this will prevent water lodgement occurring.
- Standard units fitted into frames with beads, using gaskets or mastic load-bearing strips: this system is normally used for glazing into aluminium and uPVC window and door frames. Check annually for obvious deterioration and ensure that all drainage holes are free from obstruction.
