Ellis, New Brighton, Minn., assignor to The Insolite Company, Minneapolis, Minn., a corporation of Minnesota. Application May 17, 1937, serial No. 142,962 3 Claims. (Cl. 72-16) This invention relates to the'art of building and the primary object is to provide an improved construction of walls and the like, wherein the plaster is carried by a base material, which, in' 5 turn, is carried or supported by studding or other rigid means forming the central portion of the wall. Another object is to provide a substantially air tight jointed plaster base that is moisture and 10 vapor proof, the same consisting of a series of slabs, panels or boards having a water-proof coating upon the surface to which the plaster is applied. Further and more specific objects will be dis 15 closed in the course of the following specifica tion, reference being had to the accompanying drawing wherein: ` used but it is to be understood that other types of joints may be resorted to as long as a tight joint is provided. To prevent opening of the joints during plastering, suitable means is pro vided for locking the joints. A very satisfactory means `of accomplishing this is by securing to one slab a rigid means I5, which extends across the joint and contacts the adjacent slab. The surface of the base material which receives the plaster, is coated with water-proofing mate 10 rial and preferably with a water-prooiing mate rial that increases the bonding of the plaster. Among the water-proofing materials that havegiven satisfactory results are asphalt, asphaltum, tar, pitch, gloss oil and the like. The water 15 proofing material prevents moisture from enter ing the plaster base material I3. Figure 1 is a view of the plaster base material For the most eflicient results the surfaces of provided with a water-proof coating on one face. , the base material facing the air spaces should be 20 Figure 2 is a sectional view with parts broken provided with a vapor seal I8.

Figure 4 is a sectional view of a wall structure 25 in which the vapor and moisture proof plaster base is used. 30 - In air conditioned buildings much diñ‘lculty has been experienced in the passing of moisture from the interior of the building> and condensing in the air spaces. In cold weather this condensate freezes and forms a coating of ice..on the inner surfaces or «the air spaces. By the use of this invention this undesirable condition cannot oc 35 4 cur. \ factory results as a vapor seal. f It is to be understood that many variations and modifications may be made that fall with in the scope of the invention. 'I'he water-prooñng 25 and vapor-proofing materials mentioned have given excellent results but it is to be understood that any material may be used which gives a water-proof coating on the plaster receiving face 30 and a vapor-seal on the opposite face. What I claim is: l. A building wall construction comprising sup porting members, and slabs of porous plaster re , ceiving material secured thereto with‘their rear 35 'I'he slabs or panels forming the plaster receiv faces coated with vapor-proofing material and ing base, to give satisfactory results must remain . facing hollow wall spaces between the supporting closed at all times and particularly during plas members, the plaster receiving faces coated with tering.' If plaster enters the joint during plas water-proofing material, and joints lof the base tering the joint will remain open and the air seal material locked against opening during plaster 40 is broken and moisture and vapors are easily transmitted to the air spaces in the wall. The 'joints occurring between the supporting mem bers should be so arranged that they will remain 45 closed at all times. Referring to the drawing in detail I0 is rep resented studding or other supporting members to which are secured sheathing Il, which forms at least a part of the outer wall of a building. 5 O Secured to the studding is plaster base material 13. The plaster base material may be in the Aform of an insulatingboard or slab. Vegetable fiber board, gypsum board and the like have given highly satisfactory results. The plaster base material should be provided 5 , with relatively tight joints and-an air tight joint of the form of an overlapping arrangement gives . excellent results. Overlapping joints l4,-may `be ` ing. , 2. A building wall construction comprising sup porting members, and porous plaster receiving material secured thereto with their rear faces coated with metallic vapor-proofing material. the 45 plaster receiving faces coated with waterproofing material, and the joints of face material locked against opening by applied plastering pressure. 3. A building wall construction comprising sup porting members, and slabs of plaster-receiving material secured thereto with their rear faces substantially completely covered with thin foil vapor-proofing material and facing hollow wall spaces between the supporting members', the plaster-receiving faces coated with `water-proof- f ing material, and the joints locked against open ing during plastering.
