Smoke Alarm &
Insulated Hot
Water Pipes
to the tubes, and it comes back this way. So actually, I’m just
going to test the difference in the temperature here. Pretty hot.
Ouch, really hot. So, it is a sunny winter’s day outside. And so
those evacuated tubes are definitely working fantastically well.
Underfloor
Insulation
one after the other, and glue them up under the galvanised
deck. We used water-based liquid nails to do that. They fitted
together just like a jigsaw puzzle, making little still air pockets,
which you need for reflective insulation to work properly. So
that’s what we did and it’s still there and working today.
Firstly, we decided to put a smoke alarm up here because
if there’s a fire that happens to get started in the roof, this
is likely to warn us a long time before a smoke alarm in the
house would do.
The other thing is the hot water system here. We’ve got a
low-pressure copper tank with 400 litres of very hot water. So,
this hot water pipe here is pretty well insulated. And this is the
return from the tubes on the roof. Down below here, we’ve
got the flow to the tubes on the roof. So it goes out that way

Because this house is a slab on stumps, it gave us the
opportunity to insulate under the concrete slab. It’s great
thermal mass but not a very good insulator. So normally under
a floor, you would use the polyester rolls between the joists,
which are fantastic. But under this floor is a galvanised tray
that was used to pour the slab on top. And so very difficult to
fit any kind of bulk installation to that.
So what we had to do was invent our own insulation and we
decided to use reflective insulation. So you can see here we’ve
got 15mm Foilboard cut into 600mm tiles and fitted with this
25mm border on two sides. What enabled us to lap them

Insulating The
Cathedral Ceiling
We’re currently in the roof, looking over the cathedral ceiling.
And what we can see here is the original fibreglass bats laid
on black plastic over the cathedral ceiling, and then on top,
we’ve actually fitted R2.5 Underfloor Insulation Rolls that were
pulled across the cathedral ceiling. You can also see that
while the cathedral ceiling actually holds up the roof, it is not
the roof itself.

Draft Stoppa
We are over the bathroom now, and specifically, we’re
looking over the exhaust fan. This is a Draft Stoppa that’s
fitted over the exhaust fan. It’s got two flaps that are pretty
carefully weighted. When the exhaust fan is on, they tip up
and the moist air comes out. When the exhaust fan switches
off, they just fall down. Now you can probably hear that
clickety-clack sound that they make. This is an old model.
The newer models have got little rubber bumpers on them
so that they don’t make that sound.
