Wooden (Timber) Joinery is often what sets apart one building from
another.
It is an area of highly specialized craftsmanship. It is
therefore important that you take your time in selecting who
manufactures and advises on care and maintenance. You need to be certain
that they are professionals who work to international standards and
guarantee the quality of their work.
Registered Master Joiners provide this certainty.

Guarantee Act.
Inaugurated in 1950, NZJMF has registered Master Joiners
throughout New Zealand who are committed to providing professional
standards of service and workmanship in the field of joinery and Kitchen

Exterior Timber Joinery Care and Protection
Exterior timber joinery is a premium product, which requires a level of
protection to enhance the properties of the product. It is recognised
exterior timber joinery is not 100% wind and rain proof , it is constructed
for sheltered exterior use and should not be exposed to driving rain ,
direct sunlight or extremes of humidity. In locations where extreme weather
conditions are found, additional installation precautions maybe taken to
improve the products performance, such as the installation of seals, which
are not considered normal trade practice.
The
minimum protection for timber joinery is as follows:
-
All Joinery items must
be sealed on all 6 faces prior to installation including hardware
penetration
-
Oil
based systems only to be used, following the coating manufacturer's
instructions and advice
-
4 Coat system being one
primer coat one undercoat and two topcoats.
-
The bottom and top of
the sashes and doors must be sealed
-
When painting the
putty, the paint must overlap the glass by at least 2mm.
-
Appropriate flashings
must be installed.
-
Joinery with wet
plaster must have at least two protection coatings prior to plastering.
-
Dark colours void any
Guarantee.
-
Timber joinery be
installed by a qualified builder.
If you
choose to ignore these recommendations the warranty is void.
Glazing
-
Use neutral cure sealants only.
-
No tinted putty to be
used for exterior use.
-
Timber glass beads
should be fitted using non ferrous fittings.
-
No glass to be
installed unless rebates have been primed and sealed.
Shrinkage and or expansion does occur from seasonal changes in temperature
and moisture. Minor warping or twisting up to 6mm is expected as normal for
timber joinery. Variations in colour, texture or grain of timbers are a
natural occurrence for which the manufacturer can not control and are not
considered defects but part of the natural beauty of timber.
Insulating
Glass Units
Insulating
Glass Units (IGUs) are designed to provide thermal
insulation for building envelopes. They are used to
reduce building heat loss and heat gain depending on the
climate and IGU combination. Insulating Glass Units are
sometimes called Double Glazing, Double Glass Units (DGU)
or Sealed Insulating Glass Units (SIGU).
Energy Efficiency
Traditionally the
housing energy efficiency building codes in New Zealand
have lacked recognition of the insulation properties of
windows, and have concentrated on providing minimum
thermal resistance values (R Values) for the roof, floor
and walls only.
The new
Standards have included glazing and focus on the
excessive heat loss through the area of single glazing,
which is typically 40 to 45m2 on an average house but
can be much larger in modern house designs. Extensive
cost benefit analysis has been done to show how the
correct insulation of a house can improve the energy
efficiency of the house and provide energy savings and
improved comfort for both the owner and the country as a
whole.
How IGUs Work
Clear monolithic
glass accounts for less than 5% of a window’s insulation
value, the rest being supplied by the still air layers
of the environment on either side of the glass. Since
the heat flow resistance of still air is much greater
than that of glass, a glass unit made of two panes
enclosing an air space will have about twice the
insulation value of a single pane window (half the heat
loss).
Triple pane units
with two sealed airspaces have an insulating value
approximately three times that of single glazing. This
is why double and triple glazed units are called
Insulating Glass Units as they provide insulation to the
windows of a building, like fibre-glass insulation
provides insulation to the wall.
The Benefits of IGUs
- Reduce heat loss.
- Save energy.
- Reduce condensation.
- Increase comfort.
- Reduce noise.
- Reduce heat gain.
- Reduce glare.
- Reduce fading.
- Increase security.
Insulating
Glass Units retain much more heat in a room during
winter reducing heat loss and saving energy. They reduce
noise penetration and window condensation and provide
warmer zones near windows to increase comfort.
For summer, with the use of solar control glass, they
can reduce heat gain, glare and fading and increase air
conditioning efficiency. They are harder to break than
single glass and the shards normally stay in place after
breakage, increasing security.
