Putty

Whilst putty fronting is not an industry-recognised method for the glazing of insulating glass units we do acknowledge there are many situations where this may be called for and as such suggests the following glazing methods may be of interest.

Slimtech Double Glazed Units Glazing Method

  • Bedded in Hodgson 66 Butyl
  • Seal the void around the edge of the unit with Hodgson Silfix U9 to protect the hot melt seal around the unit
  • Foreputty sash with Hodgson Multipurpose Putty or Hodgson Linseed Oil Putty
  • It is necessary to paint over the putty every 5 years inland and 3 years in coastal areas. When putty cracks, it is because of lack of paint protection

Surface Preparation

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.

Hodgson Silfix U9 Method

  1. Bed the Heritage Sealed Unit® into the frame using Silfix U9 and fill voids
  2. Use a 2mm setting block to adjust the unit
  3. Make sure silicone protects the sealant of the unit
  4. Allow the Hodgson Silfix U9 to develop a tack free skin
  5. Finish with Hodgson's Linseed Oil Putty

What is the Guarantee

5 Years if glazed using correct glazing method.
