Features of the New Long-Bell Airtite Window Frame

A new windorv frame having unusual and commendable "weather-proof" features has been placed on the market recently by The Long-8e11 Lumber Company. It is known as the Long-Bell Airtite frame and is manufactured at the cornpany's plants at Longview, Washington, of kiln-dried Douglas fir.

Di"cussing the neu' frame, Thos. A. Kemp, manager of the Long-Bell frame sales department, said:

"Our {,irtite frame is in no way the result of merely tryIeJrfrf,el& 'Airtite" ll'lrrdorr Irnrrrrr of distribution and service. When standard products can be improved, and if those improvements are piactical, they should be made. Consequently, we have been'studying frames for years and the Airtite frame is the practical result of our engineers' studies and experiments to provide a window frame that would meet the requirements of present-day ins.rlation standards. It is said that 25 per cent of the heat loss or infiltration is at the doors and windows. This is in addition to the 25 per cent loss through the glass."

The Long-Bell Airtite frame has the following new featrrres :

Beginning with the Drip Cap, the bottom is rabbetted so that it makes a rveather-proof joint with the head casing. Next, the Blind Stops are rvorked with a wedge shaped tongue on both sides-one tongue fits into a wedge shaped q.roove in the edge of the jamb-the other into a wedge shaped groove in the back of the casings.

The bottom edge of the Head Casing has a similiar sroove running its full length and then the Side Casing has wedge shaped tongues on the ends, thus making i rveather-proof joint where they join with the head casing.

The outside shoulder on the Sill is a full one-quartir of an inch deep, lvhich permits an absolute weathei-proof joint with the storm sash. The Sill is double horned for the Blind Stop, the inside horn extending 2fu,, beyond the hack of the jamb. This ,construction feature provides a rveatherproof joint for the outside casing.

By moulding the face of the sill, the manufacturer has maintained the same thickness at both shoulders; therefore, to make a tight fit where the sill goes into the dado in the jamb, the bottom of the sill is moulded in such a manner as to make both top and bottom lines parallel. This assur,es a tight joint along-the entire width of-the jamb.

Other Long-Bell frame features incorporated in the Airtite frame are : ing to give the trade 'something difierent.' We do not approve of such practice, especially in the building industry. Too often dealers and jobbers stock certain products and then, before they have moved their stocks, fincl they are out-of-date because 'something different' has come on the market.

Kiln-dried Douglas fir and heartwood throughout. This mature wood is claimed to be the most durable, and when frames are made with it, and properly constructed, they should last the life of the building.

The standard Airtite frame is made with all exposed parts of vertical grain Douglas fir. This assures free-running sash and satisfactory paint jobs.

"On the other hand, we do believe that the suc,cessful manufacturer, jobber and dealer are those who keep everlastingly at it, trving to better their products and methods

NEW

The Airtite is a K. D. frame, consisting of. seven units and is put up in two metal banded bundlis. "As we see it," savs Mr. Ke_mp, "this new frame has two very impor- tant features. One, it is weather-proof. The oth-er is the ease of and speed with which it cin be assembled. Many actual tests show that this frame can be assembled on the iob in less than ten minutes. Every member of this frame interlocks with another and there is only one way that it can be assembled. There is no chance to go wrori_s."
