I have previously carried out a worked example of the insulation of a Brick Veneer Wall, so as a comparison here is double brick wall.
I have also shown (in brackets) the effect of using a hebel block in place of one of the brick ‘leaves’:
Outside surface air layer
Condensation, a minor inconvenience, or a major problem?
A little condensation on windows is easily dealt with, . . . . . . but heavy condensation in poorly ventilated corners can lead to mould damaging your walls, ceilings, or even your clothes.
Why does Condensation Occur
Condensation in a building occurs when warm air, [read more...]
Without effective insulation more heat is lost through the roof than either the walls or floor.
There are a range of options for insulating your new home roof with some insulation materials having different effects in summer and winter.
Here are the calculations for my last new house which had a tiled roof with [read more...]
It’s not always possible to build in a quiet area so there are a number of techniques for reducing noise that you can use in your new home.
Here is a quick review of the options:
Minimising windows facing the noise. OK as long as the noise source isn’t on the [read more...]
I have previously posted about the relatively small heat loss from a slab on ground But what if you have got in slab heating, or just want to minimise heat loss/gain from your house?
This sketch shows the placement of the insulation, if you can arrange for the builder to install it [read more...]
I have previously posted about the Heat Loss from a Slab Floor so how does that compare with a suspended timber, or particle board, floor?
Well its not as bad as you might think because the the space under the floor acts as a Buffer Zone between the room and the external temperature. (Unless you [read more...]
Why is there less fuss about insulation under a concrete raft slab than ceilings and walls?…………well here are a few interesting facts:
A thick layer of earth provides a reasonable amount of insulation. The soil contributes to the thermal mass of the structure which helps smooth out any temperature variations. The temperature of the ground [read more...]
How would you like to be mowing the roof of this house?
This is a ‘Green Roof’ something which is quite common in many Northern Hemisphere Countries but not so common in Australia.
They can work well in keeping a house warm with around 2-300mm of soil providing good insulation.
