Photo log of Wood Fibre Board demonstration action
Training was given by Chris Brookman, from Back to Earth, an industry expert
who achieved Passive House standards by building with taped wood fibre board.

Travel and visit to Silverton Passive House
Date: 9th December Time: 10am – 3pm Venue: Petroc, Tiverton Campus, Bolham Road, Tiverton, EX16 6SH
Theory of the properties and performance of wood fibre board
Chris Brookman’s presentation
about the properties and uses of
wood fibre board, identifying the
different types and how and where
they are used in the building
process.
Chris brought in samples of wood fibre products to show in the classroom and
use in the workshop session.

Wood fibre insulation boards used internally and
externally for new builds and retro fit. The soft layer fits
snugly, pushing onto rough and uneven surfaces, which
helps to prevent leakages as well as allowing uneven
surfaces to be rectified in most cases.
Case Studies and achieving high standards of thermal regulation including
Passive House
Presentation of case studies of
different projects using wood fibre
board, including retrofitting,
commercial building project aimed
at achieving Passive House
standards, and Silverton Passive
House.
Start of demonstration.
First layer of polystyrene blocks
being fixed into place.
This was to demonstrate the need
for a waterproof protective layer to
be placed underneath the wood
fibre board to prevent water
ingress.
The aluminium tray that Chris is
showing the group is called
UdiBASE plinth starter track. This
is designed to protect the bottom
edge of the insulation if you are
not insulating down in to the
ground.
Special fixings are UdiASSEMBLY
timber fixings used on the wood
fibre board to prevent leakages.
Trimming the interlocking edge off
of the board where the units will
need to butt up against each other
to make a good air free join.
The Glue is a special adhesive
and is specifically designed to
stick the wood fibre to most other
materials. It sticks to
polystyrene, plastics, masonry
and timber but is a water based
acrylate glue.
Deomstrating how to attach the
fixings.
Several pieces of wood fibre board
in place.
Visiting the offices at Silverton
Passive House. Chris gave
participants a tour of the Passive
House and offices on site. The
office was built as a practice run to
try out building techniques to
highlight any potential problems
with the planned build and for
training purposes for the workforce
before they started on the main
build.
The exterior of Silverton.
The large overhang on the eaves
as mentioned in the presentation.
In the kitchen, Chris gave a talk
about the interior of the house and
the ventilation system and the
efficiency of the system.

In the plant room of the house, from left to
right, there are buffer tanks for the bore
hole (grey tank left hand side of photo) the
ventilation system (big box with the big
pipes running from) and in the corner you
can just see the boiler. There is also athe
thermal store under the stairs, electrical
consumer units, cat 6 network cabinet and
also the monitoring and data logging
equipment.
