Benefits of technology

"The present invention provides a hold down clip that is installed on a rafter before a roof is put on a house. This clip creates an air insulation gap between the rafters, which is determined by the length of the clip's legs. The clip has a flat horizontal plate that is attached to the rafter and curved legs that hold the insulation tightly against the rafter's sides. This invention helps to improve the insulation of the roof and reduces energy loss during the construction process."

Problems solved by technology

One reason for this increase in interest in insulation of various types is the drastic rise in energy costs, including the cost of heating oil and the cost of heating homes with other sources of energy.
The drawback in this type of solution is that it requires the batt-type insulation.
Furthermore, after installation, the vulnerable paper covering of the batt-type insulation is exposed and may be damaged by contact from within the dwelling.

Embodiment Construction

[0011] Referring first to FIGS. 1A and 1B, there is illustrated a rafter hold down clip 10 of the present invention. The rafter hold down clip 10 comprises a substantially flat, horizontal plate 12, a first leg 14, and a second leg 16. The hold down clip 10 is preferably formed by extrusion of rigid polyvinyl chloride (PVC) and then cut to length, although other materials may be used. Thus, the plate 12, the first leg 14, and the second leg 16 are formed as an integral unit of manufacture.

[0012] The plate 12 defines a width w which is only slightly greater than the width of the rafter to which the hold down clip is to be installed, for example about 1.5 inches for a single width rafter. Each leg 14 and 16 defines a length l, which will ultimately determine the thickness of the air gap insulating layer provided by this invention, and shown and described below in greater detail. The hold down clip material is preferably about 0.062 inches thick to provide desired strength to hold the...

Abstract

A hold down clip is installed on the rafters or a building to secure a membrane between the rafters before the roof is put on the building. The rafter hold down clip and membrane create an air gap between the rafters, thereby creating an insulation layer beneath the roof. The depth of the air gap is determined by the length of the legs of the rafter hold down clip. In a presently preferred embodiment of the invention, the legs are about 1.5 inches long, and therefore create an air insulation gap about 1.5 inches deep.

Description

FIELD OF THE INVENTION [0001] The present invention relates generally to the field of insulation for building such as residences and the like and, more particularly to a system for forming an air gap for insulation beneath the roof of a residence. This invention relates even more particularly to a hold down clip adapted to be affixed to a rafter in order to form such an insulating air gap. BACKGROUND OF THE INVENTION [0002] There has recently been an upsurge in interest in various types of insulation for all types of buildings, including dwellings. One reason for this increase in interest in insulation of various types is the drastic rise in energy costs, including the cost of heating oil and the cost of heating homes with other sources of energy. [0003] One way to insulate a dwelling involves the installation of well known batt-type insulation. This type of insulation is commonly installed in the spaces between rafters and joists in roofs, floors, and walls. Many well known techniq...
