Abstract
Abstract In a channel specially designed to fasten semi-rigid mineral fibre in-sulation to masonry walls, it is known to be constructed from 20 gauge galvanized steel or other suitable material. The channel is designed to have pre-punched holes along its length for fastening of the channel to the masonry wall. The top portion of the channel is knurled to allow easy entry of the drywall screw. The unique feature of the channel are the teeth running along its length which are pressed into the surface of the butted together sections of the insulation providing a strong grip between the two adjacent pieces of insulation. Of prime importance to the success of this system is the recent technological advancements of the mineral fibre itself which allows the teeth of the channel to engage the insulation fully and hold without mechanical support rather than be repelled or pushed back by the inherent nature of the insulation material. After the insulation is secured to the masonry wall by concrete nail fastening systems, the drywall is screwed to the channel.
Description
SCHEDULE "A" I
. . _ There is disclosed a wall insulation system, and a channel section for use in such a system.
t the present time, a common construction technique, for completing the inside of a building, includes a layer of insulation formed from individual insulation boards, and an inner wall surface formed from dry wall panels. The insulation boards are secured to masonry, by means of channel sections In conventional constructions, the edges of the insulation boards are provided with slots which are cut most of the way through the board, and run parallel to an edge of the board.
With two insulation boards butted up against one another, this enables U-shape channel members Jo engage the slots at the edge of the boards. Nails are then driven through the channel members, and between the edges of the boards, and into the masonry to hold the insulation boards in position. Dry wall panels can then be secured to the channel members, by dry wall screws, and then completed in known manner. Also, in known manner, a vapor barrier is usually provided. This construction has many disadvantages. The provision of grooves or slots along the edges of the insulation boards complicates the production process, and increases the costs of producing them.
Further, it considerably weakens the insulation boards. During transportation, handling and construction, it is quite easy for the grooved edge portions to be damaged.
The present invention provided a system or assembly, intended to overcome these disadvantages. It provides a wall assembly, which comprises insulation boards assembled to form a layer of insulation; Shape channel members, with sides of the channel members formed as rows of teeth adapted to be pressed into the insulation board; and fastening elements for holding the channel sections in position, securing insulation boards to a wall structure. There is also provided a U-shape channel member having a central portion, and extending parallel to one another and generally parallel to the central portion two side limbs, with each side limb formed as a row of teeth adapted to engage an insulation board.
It has been realized that insulation boards are of a relatively low density, and low structural strength. It is for this reason that it is undesirable to provide unnecessary cuts, s ohs eta in them, as it unnecessarily weakens them, resulting in damage during assembly etc. Since the insulation boards are I
AL
of this nature, it has been realized that the provision of rows of teeth along the sides of the channel members will enable the channel members to engage and secure the insulation boards in position. In this context, it is to be appreciated that the reference to "teeth" covers any series of projections or the like, which are capable of penetrating the insulation boards to secure them, without excessive force being required, and without causing excessive damage to the insulation boards.
Further, by simply providing a row of teeth along each side of the channel member, there is no necessity to precut the insulation boards. Once the channel members are in position, there can still be portions of the insulation board having the full thickness of the board extending between the main body of the board and the portion beneath the channel.
As a consequence, the board is not weakened nearly so much as compared to conventional precut insulation boards.
By way of example, an embodiment of the invention is shown in the accompanying drawing , in which:
Figure 1 shows a perspective view of part of a channel member; and Figure 2 shows a perspective view of part of a wall formed including the present invention.
In the drawing , a U-shape channel member is generally denoted by the reference 1. As shown most clearly in figure 1, the channel member 1 has a central portion 4 and two side limbs 6.
The central portion 4 comprises a central strip 8 and stepped slightly away from the central strip 8, and coplanar with one another are two side strips 10. The central strip 8 is knurled, to receive dry wall screws. It is also pre-punched, as indicated at 12, for nails which serve as fastening elements.
The side limbs 6 are each formed as a row of teeth 14.
Each tooth 14 is generally triangular, an correspondingly shaped triangular spaces 16 are formed between the teeth 14.
These space 16 extend almost as far as the bottom of the side limb, as indicated at 18. It is to be appreciated that the number, shape and spacing of the teeth 14 can be varied, dependent upon the materials used, etc. In particular, it may prove sufficient to provide only a few teeth with large spaces in between, there simply being sufficient teeth to hold the insulation boards in place.
- 3 - to The U-shape channel member 1 can be formed from a number of different materials by various techniques, but in this embodiment it is made from 20 gauge galvanized steel.
Referring to Figure 2, there is shown a wall construction having a masonry layer or wall 20. Secured to the masonry 20 are insulation boards 22. As shown, the channel members 1 provided engaging abutting, vertical side edges of the insulation boards 22. The insulation boards 22 are of a low density, low strength material, so that it is a simple matter to press the U-shape channel members 1 into them.
After the channel members 1 are pressed into position, then nails 24 are driven through the holes 12 into the masonry 20, to secure the insulation boards 22 into position. To finish the wall assembly, dry wall panels 26 are lazed over the insulation boards 22, the dry wall panels 26 being of corresponding dimensions. Then, in known manner, screws 28 are used to secure the dry wall panels 26 to the knurled central strip 8 of the channel members 1. The gnarling assists in guiding the screws, and preventing them from slipping to one side. The dry wall can be finished in known manner.
Also, although not described, a vapor barrier can be provided in known manner.
