Heat Insulation
Q-con blocks –
Did we do it? yes – ext 150 mm int 100 mm
The benefits of those AAC (Autoclaved Aerated Concrete) blocks was well-known and once the price was much lower, it made even more sense to use these blocks in the construction.
We used them throughout, internal and external. Maybe overkill, I don't know, but it made for a rapid construction due to the bigger block size against traditionally-used red brick. Although the red brick is more 'traditional' the brief for this build was traditional appearance but up to date building technology. None of the block work would be visible once finished
Roof insulation
Did we do it? yes
This one was pretty much a 'no-brainer'. Some great comment and advice from TD members, plus my knowledge of the benefits gained from build story read-ups before i started and this was fitted under the TD Towers roofs
Ceiling foil
Did we do it? - yes
There were two schools of though on this one with some suggesting it might not be necessary. In the end though, I figured, as much heat as possible to be kept away from the living areas was a good long-term benefit. the ceiling insulation was fitted. I made sure the roof void would also be flushed of heat though.
Air vents
Did we do it? - yes
To remove the heat build up in those massive roof voids, we needed a venting system, The builder looked to traditional roof and copied the vents in the gable ends. so traditional look, traditional practicality. heat efficiently removed. the high pitch of the roof was lifting the hot air up and away from the house in any case which further assisted (main roof height over 5m)
Roof Fan
Did we do it? - no
This one was suggested way back and seemed like a good idea. we did not do it straight away as the airflow from the vent arrangements was working well and since electrical efficiency / conservation was a build brief we decided not to fit the fans. the good thing is, we can always go back to fitting a fan in the roof void if it does become necessary. Options are there still
Narrow window
Did we do it? - yes
This worked out well. the traditional appearance was for narrow windows, not panorama or picture windows, which while letting in a lot of light also let in a lot of heat, potentially. we went with tradition as it was the brief, but the windows were glazed to insulate inside from outside temperatures. there was some tip of the hat to modern variants though,. as we had large folding windows in the bedroom, dining room (2) and main living room. All of those though were under very large overhangs preventing direct sun-rays from heating up the rooms. traditional houses also had large openings into rooms, so we followed tradition, but installed modern glazed units, again to seal off from heat and also of course for security.
Tinted glass
Did we do it? - yes
PJ was wanting this. I was easy either way but the small additional benefit of heat protection swung us on to it. a soft green tint actually enhances the appearance of the house
Roof overhang
Did we do it? – yes
Another look to tradition, where open window style was somewhat protected by roofs overhanging to reduce the suns effect in the rooms. we followed it even though the windows were glazed, as it looks correct, and traditonal appearance was the brief. we did not fit over the lower floor windows but that can be added later if required.
