With partial fill insulation it would be necessary to leave a 40mm air cavity so the overall width of your cavity is going to be 180mm or just over 7 inches. I would be concerned about this in a standard cavity wall with 2 conc. block leafs.i like the sound of the aerobord 140mm it comes with wall ties and at 0.019 u value (if thats true)it's pretty good
My builder filled the cavity and both the builder and I regret he did it - we've had alot of problem with damp - builder filled the cavity in 2 other houses and said he had same problem - also spoke to another builder last week who said that cavity filling was not a good method - he also said that it was important to keep the cavity air tight - as whatever inches of air were left after the insulation board would help the insulate the house - if the air was moving - it would not help.
Although I have put insulation in the cavity cost around €2000 I am kinda of suspicious that it does give value for money. However good that the blocklayer tries mortar will fall down between it and the wall creating a space. What purpose does it have or what good does it do in the cavity? Would one be better to have insulated boards or the same insulation on the inside of the house? This is buggin me
guy from aerobord reckons a 150mm cavity(ties come with the insulation)the boards have little 10mm ridges that form a way to channel any moisture down,cant remember are the ridges inward or outward touching the outer leaf (i think inward) i would have a fear of the fulfill beads for the damp reasons.can anyone say if an insulated cavity(lets say 60mm kingspan)with interior insulated slabs would get mould or condensation in future years at a party/outer wall junction as some suggest in forums??would slabbing all interior walls be the answer if that is true or is that just too expensive in the real world.thanks ollieWith partial fill insulation it would be necessary to leave a 40mm air cavity so the overall width of your cavity is going to be 180mm or just over 7 inches.
