Abstract

A profiled insulating underboard for insulating and aligning metal or plastic siding panels is disclosed. The underboard is formed from a suitable insulating material into a sheet having one substantially flat planar surface and an opposed surface with a configuration or profile which corresponds to the inner contour or profile of the siding panel so that it will fit snugly against the inner surface of the siding when installed. Each sheet of underboard, which is received against the exterior wall surface of a building, has a series of integral projections spaced along one longitudinal edge surface so that adjacent sheets are automatically spaced from each other to permit ventilation and help prevent moisture build up once the underboard and the siding have been fixed to the exterior surface of the building.

Claims

1. In combination with a building presenting an external support surface, a wall covering system for the building, comprising:

(A) at least one sheet of insulating material having

(1) a generally rectangular planar configuration,

(2) a substantially flat rear surface, and

(3) a profiled outer surface;

(B) a plurality of siding panels each having a connecting flange and a nailing strip on its top edge and a return element on its bottom edge;

(C) said profiled outer surface of said sheet of insulating material being contoured complementally with the inner surfaces of said siding panels;

(D) attachment means passing through said siding panels and said insulating material and engaging said support surface to secure said siding panels and said insulating material to said support surface; and

(E) said sheet of insulating material having a series of laterally extending, integral projections on one longitudinal edge surface.

2. Profiled, insulating underboard and attachment means for use with standard siding panels and a support surface, comprising:

(A) a sheet of insulating material having

(2) a generally rectangular planar configuration with opposed top and bottom surfaces interconnected by opposed edge surfaces,

(2) a substantially flat rear surface,

(3) a profiled outer surface contoured complementally with the inner surface of the siding panels, and

(4) a plurality of laterally extending integral projections on at least one edge surface

(a) whereby laterally adjacent sheets may be mechanically spaced from and aligned with each other a distance equal to the length of said projections; and

(B) the attachment means being adapted to pass through the siding panels and said sheet of insulating material and engage the support surface to secure the siding panels and said insulating material to said support surface.

3. Profiled, insulating underboard and attachment means for use with a support surface and a standard siding panel having a connecting flange and nailing strip on its top edge, a return element on its bottom edge and a single course interconnecting said connecting flange and said return, comprising:

(A) a sheet of insulating material having

(1) a generally rectangular planar configuration,

(2) a substantially flat rear surface, and

(3) a profiled outer surface including

(a) a plurality of courses each approximating the length of the single course of the siding panel between the connecting flange and the return;

(B) the attachment means being adapted to pass through said siding panels and said sheet of insulating material and engage the vertical support surface to secure said siding panels and said insulating material to said support surface;

(C) wherein each of said courses of said sheet extends away from the plane of said rear surface from its top edge to its bottom edge and has a bottom return edge disposed substantially normal to the plane of said sheet;

said bottom return edge merging with the top edge of the next adjacent course; and

(D) said sheet of insulating material has a series of laterally extending integral projections on one longitudinal edge surface.

4. Profiled, insulating underboard and attachment means for use with a support surface and a siding panel having a connecting flange and nailing strip on its top edge, a return element on its bottom edge and two identical courses interconnecting the connecting flange and the return, comprising:

(A) a sheet of insulating material having

(1) a generally rectangular planar configuration,

(2) a substantially flat rear surface, and

(3) a profiled outer surface including

(a) a plurality of courses each being subdivided into two courses and approximating the length of the two courses of the siding panel between the connecting flange and the return;

(B) the attachment means being adapted to pass through said siding panels and said sheet of insulating material and engage the vertical support surface to secure said siding panels and said insulating material to said support surface;

(C) each of said courses of said sheet extends away from the plane of said rear surface from its top edge to its bottom edge and has a bottom return edge disposed substantially normal to the plane of said sheet;

said bottom return edge merging with the top edge of the next adjacent course; and

(D) said sheet of insulating material has a series of laterally extending integral projections on one longitudinal edge surface.

5. Profiled, insulating underboard and attachment means for use on a support surface with a standard siding panel having a connecting flange and nailing strip on its top edge, a return element on its bottom edge, and a single course interconnecting said connecting flange and said return, comprising;

(A) a sheet of insulating material having

(1) a generally rectangular planar configuration,

(2) a substantially flat rear surface, and

(3) a profiled outer surface including

(a) a plurality of courses each approximating the width of the single course of a siding panel between the connecting flange and the return;

(B) the outer surface of each of said courses sloping away from the plane of said rear surface from its top edge to its bottom edge and having a bottom return surface disposed horizontally and substantially normal to the plane of said sheet, said bottom return surface joining the bottom edge of one course with the top edge of the next adjacent course;

(C) a series of laterally extending integral projections on one longitudinal edge surface; and

(D) the attachment means being adapted to pass through said siding panels and said sheet of insulating material and engage the vertical support surface to secure said siding panels and said insulating material to said support surface.

6. Profiled, insulating underboard and attachment means for use on a support surface with a siding panel having a connecting flange and nailing strip on its top edge, a return element on its bottom edge and two identical sub-courses interconnecting the connecting flange and the return, comprising:

(A) a sheet of insulating matering having

(1) a generally rectangular planar configuration,

(2) a substantially flat rear surface, and

(3) a profiled outer surface including

(a) a plurality of courses each being sub-divided into two sub-courses and approximating the combined width of the two sub-courses of a siding panel between the connecting flange and the return;

(B) the outer surface of said sheet sloping away from the plane of said rear surface from its top edge to an intermediate point and having a first return surface disposed horizontally and substantially normal to the plane of said sheet, said outer surface then sloping away from the plane of said sheet to the bottom edge of said course, a second return surface disposed horizontally and substantially normal to the plane of said sheet and joining the bottom edge of one course with the top edge of the next adjacent course;

said bottom return edge merging with the top edge of the next adjacent course;

(C) said sheet of insulating material having a series of laterally extending integral projections on one longitudinal edge surface; and

(D) the attachment means being adapted to pass through said siding panels and said sheet of insulating material and engage the vertical support surface to secure said siding panels and said insulating material to said support surface.

7. A method of installing and insulating standard siding on a planar wall surface comprising the steps of

(A) temporarily applying a sheet of insulating underboard having a planar rear surface and a contoured outer surface to a wall surface with said rear surface of said sheet in substantial contact with said wall surface;
