Description

FIELD OF THE DISCLOSURE

The present disclosure relates generally to insulative material and more specifically to installing insulative material to a surface of a structure.

BACKGROUND

Insulating buildings can lower the cost to heat or cool the interior of the building. Along with exterior walls, other structures such as ceilings and floors may also be insulated. Insulating these structures can be achieved with, for example, spray urethane foam insulative materials or fiber insulative materials.

To achieve a desired insulative material rating for such a ceiling, some methods use a spray foam insulative material that may be more expensive than fiber insulative materials. Unfortunately, high R-value batt or roll insulative material is generally too thick to fit within the framing members of the ceiling to achieve a comparable R-value to the applied spray foam insulative material. Moreover, since most roof trusses are constructed out of 2×4's or 2×6's and typical insulative material in attic area is 6 inches to 12 inches thick, installing batt or roll insulative material in the trusses may be labor intensive and may require techniques that compress portions of the insulative material that therefore decrease the R-value.

DETAILED DESCRIPTION OF THE DRAWINGS

For the purposes of promoting an understanding of the principles of the disclosure, reference will now be made to a number of illustrative embodiments illustrated in the drawings and specific language will be used to describe the same.

Insulating a surface 11, such as a ceiling 11, in an attic may allow for increased attic space while still providing a desired insulative value to the attic. As described in illustrative embodiments herein, an insulated ceiling 10, includes the surface 11 and insulative material 18 coupled to the surface 11, as shown in FIGS. 1-3. The insulative material 18 comprises an insulative-fiber layer 36 that extends away from the surface 11 and is configured to provide an insulative value. In illustrative embodiments, the insulative-fiber layer 36 is exposed when viewing the surface 11, as shown for example in FIGS. 1-3. Illustratively, the insulative-fiber layer 36 retains its approximate insulative value and approximate thickness when installed, for example, using method 100, as shown in FIG. 14. Illustratively, the insulated ceiling 10 can be a cathedral ceiling 10, an attic ceiling 10, or a crawl space ceiling 10, although the embodiments described herein can be applicable to a wide range of horizontal or vertical structures.

In some illustrative embodiments, the insulative material 18 is coupled together with surface 11 with a fastener 40, as shown in FIGS. 1-3. The fastener 40 may be a staple 40, as shown in FIGS. 1-3, or any other suitable fastener. The fastener extends through the insulative-fiber layer and into the deck 12, as shown in FIG. 2. In some embodiments, the insulative material 18 may be coupled to the surface 11 with an adhesive or other suitable means such as wires or brackets.

The insulative material 18 includes a backing layer 34, the insulative-fiber layer 36, and an adhesive layer 38, as shown in FIGS. 1-5. The adhesive layer 38 extends between and interconnects the backing layer 34 and the insulative-fiber layer 36. The insulative material 18 is arranged so that the backing layer 34 is located between a deck 12 of the surface 11 and the insulative-fiber layer, as shown in FIGS. 1-3. In some embodiments, the insulative material 18 does not include an adhesive layer, a backing layer, or an adhesive layer and a backing layer. Illustratively, in some embodiments where the insulative material 18 does not include a backing layer or an adhesive layer, the insulative-fiber layer 36 directly contacts the deck 12.

The surface 11 includes the deck 12, a first framing member 14, and a second framing member 16, as shown in FIGS. 1 and 2. The deck 12 is arranged to overlie the first and second framing members 14, 16 and includes an inward face 12A that faces the first framing member 14 and a second framing member 16. The first framing member 14 is located in spaced-apart relation to the second framing member 16. The deck 12 cooperates with the first framing member 14 and the second framing member 16 to form a cavity 20 sized to receive the insulative material 18. Illustratively, the framing members 14, 16 may be referred to as a roof truss or a stud. In some embodiments, the surface 11 does not have the framing members 14, 16 so that two pieces of insulative material 18 lie adjacent one another.

The insulative material 18 may be in the form of a batt, as shown in FIG. 4, or a portion of a roll of insulative material 18 that has been cut to size. The insulative material 18 is sized to extend over the first and second framing members 14, 16 so that the insulated surface 10 may act as a thermal block. Each of the first framing member 14 and the second framing member 16 extends away from the inward face 12A of the deck 12 a distance D1 as shown in FIGS. 1 and 2. In some embodiments, the distance D1 is about 2 to about 6 inches. In some embodiments, the framing members 14, 16 are 2×4s and D1 is about 3.5 inches. In some embodiments, the framing members 14, 16 are 2×6s and D1 is about 5.5 inches.

In an illustrative embodiment, the first framing member 14 is generally parallel with second framing member 16, as shown in FIG. 1. The first framing member 14 includes a first face 22, a second face 24, and a third face 26 as shown in FIG. 2. The first face 22 of first framing member 14 faces the deck 12.

The second face 30 of second framing member 16 faces the first framing member 14. The third face 32 of second framing member 16 faces away from the deck 12. The second face 24 of first framing member 14, the second face 30 of second framing member 16 and the inward face 12A of the deck 12 cooperate to define the cavity 20.

The cavity 20 has a width W1 that is defined by the distance between the second face 24 of the first framing member 14 and the second face 30 of the second framing member 16. The insulative material 18 is sized to extend between the second face 24 of the first framing member 14 and the second face 30 of the second framing member 16 and within the cavity 20, as shown in FIG. 2. In some illustrative embodiments, when the insulative material 18 is installed to form the insulated ceiling 10, the third faces 26, 32 of the framing members 14, 16 may not be visible when the insulated ceiling 10 is viewed from below.

The insulative material 18 extends away from the inward face 12A of the deck 12 a distance D2 as shown in FIG. 2. In some embodiments, the distance D2 the insulative material 18 extends away from the inward face 12A of the deck 12 is greater than the distance D1. In some embodiments, insulative material 18 can be selected so that D2 is about 1 inch, about 2 inches, about 3 inches, about 4 inches, about 5 inches, about 6 inches, about 7 inches, about 8 inches, about 9 inches, about 10 inches, about 11 inches, about 12 inches, about 13 inches, about 14 inches, about 15 inches, about 16 inches, about 17 inches, about 18 inches, about 19 inches, about 20 inches, or about 24 inches. In some embodiments, the insulative material 18 can be selected so that D2 is in a range of about 1 inch to about 24 inches, about 1 inch to about 20 inches, about 4 inches to about 20 inches, about 4 inches to about 18 inches, about 8 inches to about 18 inches, or about 8 inches to about 12 inches.

In some embodiments, the backing layer 34 has a width W2 that is generally narrower than the width W3 of the insulative-fiber layer 36, as shown in FIGS. 4-6. The width W2 of backing layer 34 can be sized to extend between the second face 24 of the first framing member 14 and the second face 30 of the second framing member 16, as shown in FIGS. 1 and 2. In some embodiments, the width W2 is about the same as the width W1 of the cavity 20. In some embodiments, the width W2 is less than the width W1. In some embodiments, the width W2 can be about 21 inches, about 22 inches, or about 22.5 inches. In some embodiments, the width W3 is about the same as the width between the centers of the third face 26 of the first framing member 14 and the third face 32 of the second framing member 16. In some embodiments, the width W3 is about 24 inches.

In some embodiments, the backing layer 34 may act as a vapor retarder and retard the flow of vapor from the deck 12 to the insulative-fiber layer 36.

The spacer 256 can be a wire, a rod, a strap, a combination thereof, or any suitable alternative.

A method 100 of insulating a surface 11 is shown, for example, in FIG. 14. In some embodiments, the surface 11 is generally horizontal relative to the ground or the floor. In some other embodiments, the surface 11 is generally angled relative to the ground or the floor. While this method describes installing insulative material 18, the method equally applies to the other insulative materials 318, 418 described herein.

In some embodiments, the method 100 includes providing a surface 11 including the deck 12, the first framing member 14, and the second framing member 16. The first framing member 14 is generally parallel with the second framing member 16. The deck 12 generally overlies each of the first framing member 14 and the second framing member 16 to form a cavity 20 therein. In other embodiments, the surface 11 does not include the first framing member 14 or the second framing member 16.

In some embodiments, the method 100 further includes providing insulative material 18. The insulative material 18 includes the backing layer 34, the adhesive layer 38, and the insulative-fiber layer 36. The backing layer 34 and the insulative-fiber layer 36 are spaced-apart from one another. The adhesive layer 38 extends between and interconnects the insulative-fiber layer 36 and the backing layer 34. While this method describes installing insulative material 18, the method equally applies to the other insulative materials 318, 418 described herein.

In some embodiments, the method 100 further includes locating the insulative material 18 in the first cavity 20. The step of locating includes orienting the insulative material 18 so the backing layer 34 is located between the deck 12 and the insulative-fiber layer 36. Illustratively, the step of locating the insulative material 18 may be sufficient to hold the insulative material 18 within the first cavity 20. Without being bound by theory, it is believed that in some embodiments there is sufficient friction between the insulative material 18 and the framing members, 14, 15, 16 to hold the insulative material 18 in the cavity 20.

In some examples of the step of locating can be repeated so that multiple batts of insulative material 18 are located within the cavities prior to proceeding to the next step. In some examples, the step of locating may begin by inserting insulative material 18 along the eave and working up the slope of the deck 12. In some examples, the step of locating may begin by inserting insulative material 18 at the peak of the deck 12 and working down the slope of the deck 12. In some embodiments, the step of locating may begin at any point in the deck 12.

In some examples, insulation stops are inserted prior to proceeding to the next step. In some examples, insulation stops are inserted prior to the step of locating the insulation. In some examples, the insulation stops are inserted after the step of fastening the insulative material 18. Illustratively, the insulation stops may provide a space so that air may pass through the insulated space.

In some embodiments, the method 100 further includes fastening together the insulative material 18 and the deck 12. The step of fastening uses a fastener 40 that couples the insulative material 18 to the deck 12. The fastener 40 extends from the insulative-fiber layer 36 to the deck 12. In some embodiments, the fastener 40 extends from the insulative-fiber layer 36 through the backing layer 34 and into the deck 12. Illustratively, the step of fastening the fastener 40 may be performed with a pneumatic stapler, a staple gun, or any suitable alternative. Illustratively, the insulative material 18 recovers its original thickness after the step of fastening so that the first face 44 is generally uninterrupted, as shown in FIG. 14.

In some embodiments, the surface 11 further includes a third framing member 15 located spaced-apart from the first framing member 14 to locate the second framing member 16 therebetween. The third framing member 15, the second framing member 16, and the deck 12 cooperate to form a second cavity 21 therein. In some embodiments, the method 100 further includes repeating the steps of providing, the step of locating the insulative material 18 in the second cavity 21, and the step of fastening the insulative material 18 to the deck 12 in the second cavity 21 to form a continuous insulative material surface that overlies the framing members 14, 15, 16 when the surface is viewed from below.

In another embodiment, the method 100 further includes coupling the support bracket 252 to a framing member 14, 15, 16. In some embodiments, the step of coupling the support bracket 252 to the framing member is performed after the insulative material 18 is fastened to the deck 12.

In some embodiments, the mineral wool roll or batt of insulative material (e.g. insulative material 18) that has a reinforced mat/facing laminated to one of the major surfaces (e.g. backing layer 34) may be used. The insulative material (e.g. insulative material 18) may be placed with the facing side (e.g. backing layer 34) upward in a horizontal position toward the roof deck (e.g. deck 12) in an attic or facing upward toward the floor (e.g. deck 12) in a crawl space between the framing members (e.g. first framing member 14 and second framing member 16). A pneumatic staple gun may be used to fasten the underneath side of the mineral wool roll or batt (e.g. insulative material 18) directly through the insulative material (e.g. insulative-fiber layer 36) and reinforced facing (e.g. backing layer 34) into the roof deck (e.g. deck 12) or floor (e.g. deck 12) of the crawl space.

The staples (e.g. fastener 40) may hold the reinforced facing (e.g. backing layer 34) tight against the roof deck (e.g. deck 12) or flooring (e.g. deck 12) in the horizontal position and hence the insulative material (e.g. insulative material 18), since the facing (e.g. backing layer 34) is laminated to the insulative material (e.g. insulative-fiber layer 36). This application (e.g. method 100) may decrease the possibility of the insulative material (e.g. insulative material 18) falling since it is mechanically held in place by the staples (e.g. fasteners 40).

The staples (e.g. fasteners 40) may be installed using an air powered pneumatic staple gun. In some embodiments, the fasteners 40 may exit the staple gun with sufficient force to pierce through the mineral wool insulative material (e.g. insulative-fiber layer 36) and catch the reinforced facing (e.g. backing layer 34) and pin it against the roof deck (e.g. deck 12) in the attic or a subfloor (e.g. deck 12) in a crawl space. A potential benefit to this type of application may be that the insulative material (e.g. insulative material 18) may not be compressed which would allow for the full thermal performance the insulative material 18 is intended to provide.

EXAMPLES

Example 1

The ability of the insulative material 18 to be retained within a cavity 20 with fasteners 40 was measured as described in this example. Briefly, five R19 and five R38 fiberglass batts of insulative material were exposed to a specified frequency, amplitude, and duration of vibration. The vibration conditions are those referenced in Test Method RDS100-3, an accredited test method performed by R&D Services, Inc. Visual observations were made on the batts after vibration, which is described below.

Identification of Insulation Tested

The insulative material 18 comprised a foil-scrim-kraft backing layer and bore the product identification of:

R19 FSK Eco Batt—product code 5001864

• • nominal dimensions 6.25 by 24 by 48 inches
  • manufactured on Sep. 2, 2016; or

R38 FSK Eco Batt—product code 5001778

• • nominal dimensions 12 by 24 by 48 inches
  • manufactured on Jul. 2, 2016

Five specimens of each product were selected from the available lots of material. The specimens were selected by dividing the number of batts of insulative material into five equal sub-lots and selecting one batt from each sub-lot.

Equipment and Installation

The insulative material used in this example were fastened to a test rack that simulated a 24-inch on-center roof cavity constructed with nominal two by four inch lumber and resembled the insulative material 18 and cavity 20 suggested in FIG. 1. The insulative material 18 was placed into the cavity 20 so that the backing layer 34 was located between the insulative-fiber layer 36 and the deck 12. In this example, the deck 12 was nominal 7/16 inch oriented strand board (OSB). The cavity 20 was about 48 inches long and open on both ends.

The test rack was mounted on an All-American Tool & Mfg. Co. vibration table, in a horizontal position. The insulative material 18 faced downward.

The insulative material 18 was fastened with the deck 12 the test cavity 20 using 0.25 inch crown, 0.5 inch leg staples as the fasteners 40. The staples were inserted into the insulative material 18 using a pneumatic staple gun set at 90 lb/in² (PSI). All batts of insulative material 18 were mounted with six staples. Four of the staples were placed six inches inside and six inches down from each corner. Two of the staples were placed 18 inches from each lengthwise edge of the cavity 20, on the center line of the cavity 20.

For the insulative material 18 rated R19, the staple gun trigger was pressed prior to pushing the staple gun into the insulative-fiber layer 36. For the insulative material rated R38, the staple gun was pushed into the insulative-fiber layer prior to the trigger being pressed. These methods allowed for some fiberglass insulative fibers to be “pinched” between the crown of the staple and the deck 12 to form the portion of the insulative fiber 42.

Vibration Protocol

The specified vibration protocol for this project was taken from Test Method RDS100-03 “Method for Determining the Resistance to Settling of Thermal Insulation Installed in Wall Cavities.” The conditions of this method are shown below in Table 1

TABLE 1
Vibration Protocol
Frequency	Amplitude	Duration
15 Hz	0.10 inch	24 hours

It is estimated that this set of conditions simulates the approximate kinetic energy that a residential structure will transmit to cavity insulation in a 24-year period.

Test Results

Each piece of the insulative material 18 was examined visually prior to vibration for obvious defects. Initial dimensions and mass measurements were recorded for each batt of insulative material 18. These measurements, and the calculated density, of each batt are listed in Table 2.
