Coming back now to the double glazing I mentionedbefore.Specialised double glazing requires a larger airgap between the inner and outer glass than normaldouble glazing.The gap must be at least 7centimetres.The thickness of the glass is also afactor,8 millimetres on the outside and 6 on theinside pane.It is essential that the glass be thickeron the outside that on the inside and that the gapbetween the panes of glass be a minimum of 7centimetres.
Obviously,the noise factor will have to be taken intoconsideration with the layout of the houses.Living areas will have to be designed at the backof the houses away from the highway.Bedrooms and living rooms will have to be built towardsthe back,and for those houses closest to the highway two layers of plasterboard will be neededfor the interior bedroom walls.Those rooms constructed at the front of the houses should begarages,laundries,kitchens,bathrooms and dining rooms.
I have come to the conclusion that this development should go ahead,but with variousacoustic modifications according to the position of the block in relation to the highway andintersection.
