Single 7.5 cm AAC Block Exterior Walls
The original contractor we engaged to build our house (Kittysak) has pulled out after he became concerned about my request for details on such sundry incidentals such as using rebar chairs to support the steel reinforcing. At a meeting with him I saw the look on his face when Yuri showed him a picture on Google of rebar chairs. A bit like a deer in the headlights. So we moved on and have spent some time talking with Bandee House Construction, giving them a copy of our plans and asking for a price based on these. The price came back and while it was THB 310,000 more than Kittysak's we were satisfied they knew what they were doing and would build what we wanted. This was backed up by a visit to a house under construction for another expat on the outskirts of Surin.
At the most recent meeting to finalise details on the build I was bemused to note they had quoted on single 7.5 cm AAC block external walls. The plan we gave them clearly stated double 7.5 cm AAC cavity external walls. They justified their decision by saying the single block wall will still give "nice cool house." My scepticism must have been apparent as the sales consultant went to great lengths to assure me we would be happy with the end result.
A question to forum users who have built their house using single 7.5 cm AAC blocks - how cool is the interior in the middle of May without the air con on? Is the house comfortable without using air con during the day? Comments / observations and experiences on this would be very much appreciated.
