Introducing the Reframed Initiative
The Reframed Initiative is working with designers,
builders, owners, financiers, and policy-makers to
scale up deep retrofits.
Together, we can address the housing crunch and
climate emergency.
LEARN MORE: pembina.org/reframed

Deep retrofits are:
● Healthy: cleaner air, improved comfort
● Resilient: ready for extreme weather
and earthquakes
● Low-carbon: use renewable energy and
carbon smart materials

Let’s scale up solutions that:
● Keep rent affordable
● Minimize disruption to tenants
● Return value to owners and investors

FUTURE USE
ASK OURSELVES.
ARE WE BUILDING A BETTER SYSTEM?
IF WE ARE REPLACING AN ENVELOPE WITH A MARGINALLY BETTER SYSTEM..
ARE WE IN DANGER OF REPEATING OUR MISTAKES?

WHAT ARE TAG PANELS?
PREFABRICATED, SUSTAINABLE BUILDING PANELS.
ENABLING CLIENTS TO MEET HIGH PERFORMANCE BUILDING GOALS.

BUILD UP
We created three "typical" wall assemblies to cater for
Step 1, Step 3/4 and Step 5 / Passive.
However our walls are customised depending on client
and code requirements.
Strapping
High Performance WRB
Wood Fibre insulation
Blown Cellulose in Timber
stud cavity
OSB or Plywood - Taped
Service cavity

ALT. BUILD UPS
As the system is customisable, we have created
other wall, floor and roof assemblies to work with
clients required RSI values and site conditions..
Drywall
High Performance WRB &
Strapping
Timber stud structural wall &
service cavity
OSB or Plywood Taped

MATERIALS & CARBON
SUSTAINABLE, BREATHABLE PANELS MARRY THE BENEFITS OF PRE
FABRICATION WITH LOWER EMBODIED CARBON & LOWER LIFECYCLE COSTS.

CARBON CAPTURE
There is a growing awareness that high-performance,
and energy savings, can't be "at any cost".
Building materials play an outsized role in the CO
emissions of a building.
2

MATERIALS
Inside a prefabricated wall, when used as either new build or
retrofit. Materials used, and the carbon they emit play a huge
role for future use and re-use of buildings.
Harvested timber
Wood fibre Cellulose (recycled)

AIR BARRIER
High Performance
Exterior Membranes
Wood fibre Taped OSB &
Plywood
Keeping a house or retrofit air tight is essential in keeping
users running costs low, and ensuring comfort.
Multiple Air Barriers give the best chance of achieving this,
whilst moving plumbing / electrical to the interior of the air
barriers reduces penetrations.

VAPOUR DIFFUSION
An effective air barrier is paramount. However, an assemblies
ability to be vapour "open", can help with swings in moisture,
as well as drying assemblies to the interior or exterior.
Wood fibre Cellulose (recycled)
High Performance
Exterior Membranes

HOW PREFAB BENEFITS
WHETHER NEW BUILD OR RETROFIT, PREFABRICATION HAS MULTIPLE BENEFITS
TO A PROJECT, WHETHER CLIENT, CONTRACTOR, OWNER OR END USER.

PREFABRICATED PANELS
THE FIVE BIGGEST BENEFITS TO THE SYSTEM AS WE SEE IT
Building your
investement within a
climate controlled
production facility.
Sytems that build
upon known
construction.
Reduction in on-site
trades. Ownership of
the envelope.

Having your entire

and built within the
panels.
Window openings

construction.

SUMMARY
THREE POINTS
What are TAG Panels?
Prefabricated, sustainable, vapour open - high
performance building panels.
What are the materials & embodied carbon in TAG Panels?
A mixture of timber, wood fibre, cellulose and high
performance membranes, helping reduce embodied
carbon.
How can prefabrication benefit New Builds & Retrofits?
Controlling building conditions, removing conflicts,
providing a fixed price, reducing on-site time and helping
to achieve significant performance over traditional
systems.
