Framing
Showing results 1-12 of 81
Framing outline is visible on the cladding on cold mornings
-
Condensation is forming on cladding where there is insufficient or no insulation – when walls are uninsulated or have insufficient insulation, the area of cladding between the wall framing may become colder than where the cladding is fixed to the framing resulting in condensation forming on the cladding in a pattern.
-
Condensation forming at the framing locations when the wall is well insulated - this means that, due to thermal bridging, the framing is colder at the framing locations than where there is no framing, so moisture condenses at the framing locations

Timber slat decks – rot to deck joists/bearers
-
The timber treatment was not adequate
-
The timber is at the end of its serviceable life
-
Moisture remains trapped in the junctions of framing
Timber slat decks – deterioration of decking/cladding
-
Decking and framing was installed hard against the building cladding
-
Accumulated dirt and debris is trapped against the cladding
-
There are leaks into the wall framing at fixing points
Timber slat decks – water leaking into house
-
Water is tracking along the bolts used to fix the deck to the wall cladding/framing
-
The decking/framing is hard against wall cladding
-
The decking is blocking drainage from a drained and vented cavity
-
Deck framing or decking is blocking drainage slots in brick veneer
-
Where deck joists are cantilevered out from the wall water is tracking along the joists into the building
Waterproof decks – deterioration under cantilevered balcony
-
Inadequate drainage from the balcony
-
Damage or penetrations through the decking membrane
-
Water entry into the balcony floor and/or wall framing
Waterproof decks – the deck is springy
-
There is damage to the substrate and/or framing due to water entry through the membrane or through adjacent wall claddings
-
The substrate material is not thick enough to span the rafters/joists
-
The particleboard used as a substrate has deteriorated
Waterproof decks – bubbles under the membrane
-
Poor adhesion of the membrane to the substrate
-
Glue misses (the membrane was never fully adhered when installed)
-
Moisture is trapped under the membrane
-
There is moisture in the roof space below
-
For liquid applied membranes the application had not cured properly before subsequent coats were applied
-
The framing and/or substrate moisture content was too high when the membrane was installed
Tiled deck or patio – cracking
-
Substrate shrinkage
-
Thermal expansion/contraction
-
The framing and/or substrate has too much deflection
-
There are no or insufficient tile movement control joints
-
Tiles were fixed over movement control joints
-
The concrete substrate was not sufficiently cured before tiles were laid
