Bu çaly?mada; ah?ap iskelet sistemde günümüz uygulayycysy ve kullanycysyna sa?lam, güvenli ve ysyl konfor ?artlarynyn da sa?landy?y bir sistem olu?turulmasyna katkyda bulunulmasy amaçlanmy?tyr. Bu amaç do?rultusunda ysy ve buhar geçi?ini de?erlendirmek için örnek bir proje üzerinde TS 825 Isy Yalytymy Hesap programy kullanylarak ysy kayby ve yo?u?ma tahkiki anlatylmy?tyr. Hesaplamalarda kaplama malzemesi olarak OSB levha, yalytym malzemesi olarak da ta? yünü kullanylmy?tyr. Çaly?mada ah?ap iskelet sistemin geleneksel yalytym uygulamasy ile dy?tan yalytym uygulamalary sorgulanmy?tyr.

In this context, the development of wood frame structure, the structure of carrier wadding and sheating which formed wood frame structure and their materials are examined. Then the translation of heat and vapor on a project to assess the sample program using the TS 825 Heat Insulation Calculation of heat dissipation and condensation analysis are explained. In the calculations, wooden structure was deemed appropriate to be insulated from outside.As coating materials; OSB board and rock wool as insulation material used. On the study, traditional insulation and external insulation of timber frame applications has been questioned.
