In between the rafters, there should be ridge-beams above and below, reaching up to the
janu part. This should be equal to the length of the nivra, to one part of the tuft-like element
or to one part of the rafter.
लुपा वा सुघनं वापि वलयो वंशविस्तरः।
तदर्धवेशनान्नीव्रीं वलयस्य विधीयते।। ३४

tadardha ves'ana'nni'vram valayasya vidhi'yate // 34
The width of the ridge-beam shoud be in relation to the length of the rafter or to the thickness
of the rafter or to the lierne. There should be a nivra for the lierne with a projection equal
to the half of that width.

For the sake of placing the wooden planks, the architect should besmear a special kind of
wax known as ‘dhanurvamsa’ and fix it firmly above the rafters. Then he should cover
this with tiles made of metal or bricks and apply the ‘ashta bandhana’ for such covering.
Holes should be provided in the lierne so as to lie in between the rafters.
