ここに示した断熱下地材１は、既存横葺き屋根材２の上面に載せられるものであり、既存横葺き屋根材２の２段以上の上面に載せることができる幅を有している。
また、断熱下地材１同士の接続手段として、断熱下地材１の棟側には棟側被重なり部１ｂが、軒側には軒側重なり部１ｃが形成されており、左右方向には、一側に横重なり部１ｆが、他側に横被重なり部１ｅが形成されている。
First, the heat insulating base material 1 will be described with reference to FIGS. 1 and 2.

The position where the heat insulating property and the strength can be maintained is a position where the heat insulating base material 1 has a thickness equal to or higher than the height of the horizontal groove portion 1a below the bottom surface of the horizontal groove portion 1a. When the bottom surface of the horizontal groove portion 1a is not formed at such a position, the bottom surface of the horizontal groove portion 1a and the existing horizontal roofing material 2 are close to each other and the thickness of the heat insulating base material 1a is reduced. There is a risk that it cannot be maintained sufficiently.
Moreover, the position of the horizontal groove part 1a is near the center of the upper surface of the heat insulation base material 1 in the eaves-ridge direction, and may be formed in a position thicker than the thickness of the ridge-side overlapped part 1b and the eaves-side overlap part 1c. desirable.
そして、断熱下地材１の下面は、既存横葺き屋根材２の段差及び有効寸法に合わせた形状に形成されている。そのため、既存横葺き屋根材２の上面に断熱下地材１が載せられたとき、既存横葺き屋根材２と断熱下地材１との間は隙間無く配置されるため、断熱性が向上する。
また、軒棟方向に隣り合う断熱下地材１の上面の横溝部１ａ同士は、６０６ｍｍ以下の等間隔となる。
