‘A home of foam is going up on
a small lot in the upper reches of
Deep Cove in North Saanich.

Bob and Valerie Stewart, with
the “considerable help of a
building contractor friend, are
using one of the more: recent
insulation techniques devised by
Cano. Building. Systems. in
Calgary, Alberta, to construct
their 1,760-square-foot, — three-
bedroom home at 420 Wain Rd.

Wall. sections, complete with
window holes, were shipped from
Calgary a few weeks ago. Now
they’re up and holding a nearly
compkete roof — and drawing
startled glances from passersby.

At the Calgary factory, Cano
had packed. the spaces between
the wood joists with solid, white
polystryene: foam — the same
kind of stuff. that goes into

making heat-holding disposable

coffee cups.
“Stewart, whose background is
in electronics and communication

and worked in Calgary before.

moving. to North. Saanich,
became so enthused about. the
insulating scheme, he. not only
ordered it for his own home but
hopes to. market, and eventually
fabricate, the various house
pieces on the peninsula.
He: says, and the company’s
literature “backs him up, that

means there are cold spots where
it is thinner. But the foam doesn’t
move anda consistent ‘R’ factor

(insulation measurement code) is .

maintained in all parts. of all
walls.”’
There is also no heat loss
through the joists themselves
because the wood does not go all
the way from outside to inside.

It’s blocked by. a strip. of ins

sulating foam. ‘‘This way you get
the true ‘R’ factor you pay for,”’

“Stewart said.

pieces but: because the Stewarts
already had a truck full of walls,
posts and extra slabs of foam,
they decided to use conventional
insulation top and bottom. in-
stead.

Because there ‘is virtually. no
heat loss through» the walls,
Stewart expects his heating costs
to be 50 to 65:per.cent lower than
if he had installed conventional
insulation,

Cost for the erected walls ‘is
almost’ the same as with more
conventional. construction. No
Outside plywood sheeting is used.
Only a layer of construction

“And the: stuff’s) tough,”
Stewart. said. slamming his. fist
against. the foam. ‘No one’s
going to put a fist. or a foot
through this. And it’s a neat,
clean wall with no wood wasted

The Stewarts’ foam home will

built and ‘a number of storage

buildings have been constructed.
The Stewarts; who now live in
a trailer outside’ their. con-
struction project, are looking
forward to. the day they move in.

Stewart said, his eyes shining. ‘I
just hope it affects other people
the same way it does:me.”’

When the outside siding and
the inside wall board is on,. the
Stewarts’ home won't look a
whole lot. different than many
others. But between ‘the walls —
now there’s a difference.
