Kimsul Insulation Comes to the West Coast

The George E. Ream Company of Los Angeles, announce that they have added Kimsul Blanket Insulation to their line, and have a stock available for immediate distribution.

Kimsul is a wood product and a very interesting material. It is one of the safest, most efficient and lasting insulations known to science. It is one of the most remarkable heat stoppers ever developed, and low in cost and easy to install. Those who are familiar with insulation will recognize in Kimsul all the properties required of a good insulating will float indefinitely on water, positively identifying its resistance to moisture penetration. An ideal insulation is one of very light weight. l-inch thick Kimsul weighs -only about igO tUs. to the thousand square feet. This in itself indicates the relation of air cells which weigh nothing to fibres. material. It is composed of an expanded wood pulp containing literally millions of air cells, and is built up of a great many separate plies so that there is surface resistance between each ply. The surface of the plies is crinkled so that they do not come in contact but form little air cells between each ply.

An insulation to be practical for lumber dealers to sell must be packed so that it can be easily handled, readily delivered to the job, and conveniently installed by the customer. Kimsul answers all these requirements as it is shipped compressed in paper cartons. Each carton containing approximately 5l tlmes its apparent bulk. This is accomptisnea by expanding the insulating material by stretching the blanket a[ the time it is installed. The convenience of this will be at once recognized. Space in the dealer's warehouse is always at a premium. The footage that can be handled in one truck load is also of importance. The protected packing that permits Kimsul to be shipped along with other miterials is of equal merit. Loose insulations that will take no weight and cannot readily be bulked with other materials are a nuisance to the dealer.

The condensed packing of Kimsul appeals greatly to contractors. It facilitates distribution about the job. The packages are easily handed up through small openings or t9 c9ncealed places. The clean material and firm, well-stitched blanket also appeals to workmen. There is nothing to cause irritation of eyes, nose, skin abrasions, or otherwise annoy. The cleanliness and convenient handling of Kimsul assures a maximum of finished installations Per man per day.

It is also a great convenience to builders to have an insulation that can be installed easily either over a flat ceiling, or under a gable roof. An insulation that can also be drawn behind oi around conduit, plumbing, cross braces and other obstructions. Builders, too, like this insulation because odd pieces can be tucked into narrow spaces between ftames and other inconvenient and inaccessible places. Also, it can be wrapped around plumbing pipes for sound deadening and heat insulation.

In the application of an insulation it is necessary to retain the air cell structure independently of the problems of application and the care by the workmen. In Kimsul this is accomplished by forming the material into an elastic but compressed blanket which is secured in place and then stretched until a series of stitching becomes taut. This is' simple and almost foolproof and assures the maximum of insulating value. The value of air spaces is unquestionable and in the application of Kimsul an air space is formed between the lath or sheathing so that the customer obtains this extra value without cost. Moisture resistance is highly important and Kimsul is integrally treated with asphalt, one of the best moisture stoppers known. Kimsul blanket

The question commonly arises as to how much insulation is required for a specific purpose. The requirements of course vary with locality and conditions. For a summer climate, Double-Thick Kimsul, nominally Z-inch, applied with an air space, over a ceiling reduces the heat transfer in a ventilated attic by approximately 85/o. This can be expressed in a better way. At a typical location having a hot summer sun and a typical house having a ventilated attic and a plain plastered ceiling the temperature of the ceiling itself at the hot part of the day would be about 21o hotter than the air in the house. Obviously, this ceiling will act as a great radiator to heat the room. We have all had this experience and know what it is.

Adding Standar<i l-inch Kimsul, applied with an air space would reduce the ceiling temperature to only 6f" above the air in the room, and Double-Thick, Z-inch Kimsul to |fo warmer than the room. Obviously, further insulation would be uneconomical as the temperature of the ceiling now is so low that the rooms are no longer heated from this source in comparison with the heat that filters through walls, windows, ventilation, etc.

For winter conditions. the situation is much the same. Winter insulation. however, serves two functions. One is an out-and-out saving of fuel, which itself will pay for the insulation, and the other is of more importance, a marked increase in comfort due to the uniform distribution of heat
