Slenderpane manufacture slim doubled glazed units (Slimlite) that are thermally efficient with ultra slim sightlines, below are guidelines for glazing using Slenderpane units
Important Installation Details
Apertures must be dry before glazing. It is imperative that the glazed unit is set on glazing packers and putty glazed or totally sealed so that no moisture can find its way into the rebate and make contact with the seal of the unit. This is the most common cause of units to fail.
A non-setting glazing compound such as Arboflex 500 should be applied to the back rebate, and the unit equally compressed against it to provide an even all-round bed of approximately 2 mm between glass and unit.
The unit should be seated onto suitable glazing packers to avoid glass to timber contact at the bottom of the unit and held in position by Non Corrosive sprigs or brads. (Such as Copper, Sherardized, Stainless Steel or ideally, glazing gun diamond points)
The gap around the perimeter of the unit should then be sealed with low modulas neutral cure silicone and allowed to dry for 24 hours. This is essential, the unit can then be face puttied with Arbolite metal casement or dual purpose putty in the usual way.
We do not recommend using Linseed Oil putty.
We recommend using Arbo Softening Medium if softening of the putty is required.
Glazing with Beads
Back bed with non-setting compound or silicone, seat onto glazing packers and perimeter seal with low modulus neutral cure silicone as above. Apply non setting compound or silicone to the beads and pin into place.
The beads should be pinned with Non Corrosive panel pins, as above.
It is also an option to cap the bead depending on aesthetic requirements.
If glazing with glazing tape it is advisable to seal below the tape, where the upstand meets the rebate with low modulas neutral cure silicone.
Both methods require that the putty or beads are over painted with the paint making a good seal on the glass. Painting can be carried out after 14 – 28 days depending on weather conditions.
Important – Overall we recommend that the glazing is carried out by an experienced glazier.
We do not tape the edge of our units as recommended by Bostik Butyl Hot Melts product data.
