Glazing Installation

Here we offer some simple recommended guidelines to follow when installing double glazing.

Glazing Materials

  • Hodgson Silfix U9 Low moisture Neutral-cure silicon which cures to form a flexible rubber.
  • Hodgson flexistrip a security glazing strip for double-glazing units and laminated glass.
  • Hodgson colour glaze putty
  • Hodgson multi- purpose putty
  • Hodgson butyl 66
  • Dry seal mp manufactured by repair-care a non-linseed based product manufactured by repair-care which is a durable alternative to putty.

Face-pointed Frames

Slim-care units to be bedded in back rebate with approximately 2mm of butyl (non-hardening compound) or with flexistrip and centred in rebate with spacers or packers, (the latter not required if using flexistrip) to keep the unit raised from the rebate platform completely fill the void area with silfix silicone and allow to completely cure. The units can then be putty fronted using one of the above product’s making sure there is full adhesion to the frame and glass and no ares for water to enter the glazing system.

Beaded Frames

Treat in the same way as above up to the point of putty-fronting. Timber beads to be secured against glass using nails or screws and sealed with Silfix U9 low moisture Silicone to completely seal any residual voids between glass and rebate and glass and bead. Finish with paint application making contact with glass both inside and outside. It is very important that regular maintenance of the frames and glazing system is undertaken to prevent the access of water into the glazing system.

Moisture Attack

The major enemy of insulated glass units is water. If water is trapped in contact with the seal of the unit for a period of time, the unit will fail. All glazing systems must protect the edge of the insulated glass unit, either by preventing access of water or by proper drainage and ventilation.

WARNING
Some silicones are not suitable for use with sealed units. A silicone component (plasticizer) can migrate to the primary seal causing catastrophic failure of the unit, if in doubt please contact your supplier before installing.
