Advanced Thermal Camera Technology:
is revealing the ineffectiveness of manually placed batt type insulation for use on ceilings of homes.
Homes all around the world: are
improving their comfort and savings by Upgrading their old batt insulation.

The 15 common faults of manually placed batt type insulation...
 Thermal Camera Technology has unmasked the hidden problems that cause batt type insulation to be unsuitable for insulating ceilings of homes. Batt insulation jobs with all their problems are being rectified and upgraded right throughout Canada, USA, Western Europe and the UK with the advanced
method of pumped in Cellulose Fibre. If you have batt type insulation you should have a thermal camera check to identify how many of the 15 common
faults & electrical Safety & Health issues your insulation may suffer from. Once identified ALL these problems can be rectified by Thermal Living
An insulation upgrade with Cellulose Fibre can rectify all these problems & bring your insulation up from 15% of the BCA standard to 115%.
- Gap free ceiling insulation is of paramount importance for an Energy Efficient home.
- CSIRO & BRANZ : Gaps totaling 1% to 5% halve the R-value of batt insulation.
1.Batts not fitted out into the corners and edges, particularly in low pitched roofs. such as the modern brick veneer, these batt
jobs may look reasonable when looking down on the batt insulation
from high on the roof, however on inspection out in the corners and
edges it's common to find a gap right around the perimeter of the
ceiling where there is no insulation, these gaps can be anywhere from around 3% upwards... effectively halving the thermal R- value of your insulation investment. (NOT GOOD)

 2. AIRSPACE under batt: In older styler homes Batts sit on batons between joists leaving a gap between the ceiling and insulation batt for heat transference to take place. Heat transference takes place through this airspace and the gaps.Heat leaks out in winter. Heat pressurizes into the home in summer through these pathways. insulation installer sydney batt insulation
 3. The Overlap:Overlapping timbers, batts not cut to join the
timber flush, this creates an airspace under the batt as it overlaps the timber, allowing heat transference in winter & summer.

 4.SPACES: left open/ un-insulated. Spaces where batts
fall short. Electricians interfering with insulation. Spaces where
workmen move batts to install ducted air- con.

 5.Gaps & Bowing -
Because Ceiling timbers/ joists vary in their widths
& are not always placed at standard intervals, precut batt insulation
often don't fit properly. This can result in regular occurring gaps
and bowing of the insulation batts (see 14).
 6.Compressed between timbers and not
expanding up to full thickness resulting in
reduced r-value. Shoved down under beams
crossing joists, again resulting in reduced
r-value.

 7. Batts Uneven and not flush with ceiling:Pipes Wires & Conduits create great difficulty for the
batt installer to achieve an even coverage. Often placed over a pipe...over wires ...causing the batt to not sit flush on the ceiling,
therefore creating an open pathway for heat loss & heat gain.

 8. SPACES around Down lights: Too large a space left around down lights, falling short of proper coverage. Un insulated space. downlights
 9.Placed over down lights/ fire hazard: Safety
Down light covers & Draftstoppa are recommended
to install for safety & energy efficiency.

 10.Batts split in half, used further out from manhole, quite common.
 11.Incorrect R-value installed. That is batts used with a lower R-value than recommended for the area. e.g. wall batt insulation installed
instead of roof ceiling batt insulation Or insulation batts split in half
:
 12.Batts past use by date (squashed in packet for too long) don't expand up to claimed thickness thereby reducing the claimed
thermal r-value.

 13.HEAT SINK EFFECT... diagram coming soon.
Gaps & spaces in insulation allow heat to enter your home in summer,
passing through the gyp rock directly into your home and also conducting
across the gyp rock itself under where the insulation batts have been placed, (if there
are regular gaps & spaces in your insulation) heating your entire ceiling
(gyp rock) by day 2 of a heat wave, rendering the insulation useless. In fact
the insulation is now holding all that heat in your home making it as hot as
if you weren't insulated, or maybe even hotter. This is what is generally known
as the "Heat Sink Effect".

Result: Your air- con is constantly battling to counteract this heat, This is why
Gap Free, Complete Coverage is absolutely essential.
As they say in real estate the 3 most important things are location, location,
location. With insulation it's COVERAGE, COVERAGE, COVERAGE

 14. BOWING-Oversized batts placed between joists cause batts to bow , creating an airspace between the ceiling & batt. Heat transference takes place through this airspace and the gaps.Heat leaks out in winter. Heat pressurizes into the home in summer through these pathways.

15.Blocking wall ventilation/ Extra heat gain through walls in summer. Batts pushed into eve area cause heat collected by the exterior wall that heats up the wall cavity to become trapped pressurizing through the interior walls into the home.

These 15 faults render Batt type Insulation: Unsuitable for insulating ceilings of existing homes
Very, very poor coverage.

COMPLETE COVERAGE IS VITAL: Authorities such as the CSIRO & BRANZ reveal the effect of poor coverage.
CSIRO and BRANZ Reports Reveal : Gaps & Spaces totaling 1-5% reduce the R-value of batt insulation by 50%.
