Dear Tim,
This is the letter that I said I was
happy to write for you, as I think your product is great and very beneficial.
I own a 20x6 metre single fronted weatherboard house with a north facing rear
yard. The rear addition has a semi-flat tin roof and originally, no
insulation!! The first summer 1 died. So when the iron needed replacing
conventional R2.5 batts were installed. Summer temps improved but the heat
would soon build up to unbearable levels after 1-2 days and wouldn't cool down
at night by much.
I saw Tim Renouf's product, Concertina Foil Batts Insulation, at the Melbourne
Home show, how simple in theory it was, how much sense it made and how cheap it
was. It was refreshing to meet someone who was passionate about their product.
It meant pulling up the roof iron again but it was worth it, even though 1 took
a short cut and installed them on top of the batts, which was easier than
trying to fit them underneath.
The results were very impressive. The rear section of the house can now be
called cool in summer; the heat build up is less evident and dies quickly at
night. The main roof was also done at the same time, this means that the flow
of air keeps the house comfortable. If I was able to do the walls and floor I'm
sure the results would be outstanding.
I passed my information to a neighbour
who was doing a complete rebuild. His
"builder mate" talked him into conventional roof, floor and wall
insulation. The roof and walls had fibreglass batts installed, while standard
foil insulation was draped over the floor joists. His house is still cold in
winter and builds up lots of heat in summer plus his floorboards are popping
and creaking.
Simply put the Concertina Foil Batts work!!
You can lead a horse to water but...
