Had a look at airfoam, but the amount of nightmare stories and the fact that it's formaldehyde have put me right off. Had a good look and can't see many alternatives. There seems to be a product in Aussie called RockWool, but only seems to be available here as pink batt style insulation, not pump into your wall style. Apart from removing cladding / linings, does anyone know of any alternatives? TIA.	pine-o-cleen (2955)

What I did to a south facing bedroom wall, when the room was being re-papered, was to use a hole saw to cut 75mm holes through the Gib board in the upper right hand corner of each dwang/stud space, and fill the space with polystyrene beads, such as is used in bean bags. The Gib board circles from each hole were then plastered back in place, and the wall papered.......voila....an insulated wall and no more mold forming behind dressing table etc.	Terry Porritt (14)

If there is a power point near floor level and the wiring comes up from under the floor, as in our house, then it is possible to disconnect and slide flexible conduit over the cable to prevent the polystyrene coming into contact with the cable.

1204227	2011-05-22 09:41:00	What bad things have you heard about Airfoam? They wouldn't be allowed to put it in your home if it was bad for you. Here's one story: badservicenz.blogspot.com I've read plenty of others. www.google.co.nz And did you read where I wrote that it's Formaldehyde? Formaldehyde can be toxic, allergenic, and carcinogenic.[5] Because formaldehyde resins are used in many construction materials it is one of the more common indoor air pollutants.[23] At concentrations above 0.1 ppm in air formaldehyde can irritate the eyes and mucous membranes, resulting in watery eyes.[24] Formaldehyde inhaled at this concentration may cause headaches, a burning sensation in the throat, and difficulty breathing, as well as triggering or aggravating asthma symptoms.[25][26] I don't know about you, but I don't really like the idea of having that stuff in my walls. I mean, who knows if it will seep in?	pine-o-cleen (2955)
1204228	2011-05-22 09:42:00	Isn't the goverment spending millions insulating old houses? What method do they use? They are subsidizing insulation. I believe that Airfoam qualifies for the subsidy.	pine-o-cleen (2955)

1204230	2011-05-22 12:11:00	The short answer Pine-o-clean is there is no easy way. I like Terry's innovative solution which requires a lot of work but not so bad if its only one or two rooms. Insulation foam is the simplest answer. There have been some negative reports lately but the stuff is still used and approved.	Winston001 (3612)
