Hi guys, Some of you know or remember that we just bought an old house (1950s) and moved in 2 weeks ago. We are very happy in the house, however, this week we had a day with 42 degrees warm and we were surprised the house got very hot inside very quickly. I checked the ceiling and house has insulation but it seems it is very old and thin. I'm wondering whether or not fitting a new insulation will make the house much less warmer than it is currently now? I'm looking to see if it is worth the investment in new insulation not only temperature wise aut also when we decide to put aircon at home and not getting higher bills due to the aircon working too hard to keep the temperature low. House is a concrete brick on timber floor and timber roof on top with old concrete tiles.
