Item type:Publication, Influence of the Corner Joints of the Window Frame and Sash on the Final Quality of the Window(2025-12-04); Mihajlovski, NikolaThe quality of a product is a characteristic that demonstrates how well it meets the needs for which it is intended. Given that, a window purpose is to provide light and desired ventilation to a room, while at the same time protecting the building from external influences such as air permeability, water permeability and wind resistance, we prove that it is of high quality the more it provides us with these conditions. A window as a product is a complex composition of different materials and parts. The different parts of a window include the basic structural elements, filling elements, fitting, and additional accessories. The basic structural elements of a window are the supporting frame and the window sash. The corner joints of these elements will be the target of research, in terms of how the strength of the joint of the corner segments of windows made of wooden frame, PVC frame or aluminium frame can affect the window's resistance to air permeability, water permeability and wind resistance. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, STRENGTH OF THE CORNER JOINTS OF THE WINDOW FRAME(2025-09-17); Mihajlovski, NikolaThe window as a product used in construction aims to provide natural light and the possibility for ventilation in the building where it is placed but at the same time to protect the room from external influences such as wind and rain and to prevent uncontrolled cooling or heating of the building in which it is built-in. Given the purpose, a quality window is one that protects against air permeability, water permeability and provide wind resistance. The window is a complex product that is composed of different parts that can be made of different materials. This research is focused on the area of frame joining and joint strength. This research will cover windows made from the same PVC profile but manufactured in different production facilities. The windows will be measured for air permeability, water permeability and wind resistance, and corner samples will be taken after wards. The samples are prepared according to the standard EN 514:2018 Plastics - Poly(vinyl chloride) (PVC) based profiles - Determination of the strength of welded corners and T-joints. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Analysis of heat consumption during convective wood drying of beech sawn timber of different thickness(Faculty of Design and Technologies of Furniture and Interior - Skopje, 2025-09); ; In the paper, the heat consumption of beech sawn timber with a thickness of 50,0 and 70,0 (mm) are analyzed under conditions of classic convective drying. The drying mode is compiled on the basis of data on the temperature of the drying agent (air), the relative humidity of the air and the speed of air movement in accordance with the current value of moisture in the wood. The heat consumption is analyzed in all stages of the drying cycle such as heating the wood, active drying of the wood and conditioning, i.e. equalization of the moisture in the cross-section within ± 2.0 (%). The moisture content of sawn timber at the beginning of drying is about 45,0 (%) and at the end of drying is 8,0 (%). - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Processing sawlogs into parquet blanks(FACULTY OF FOREST INDUSTRY – UNIVERSITY OF FORESTRY – SOFIA, 2024-12); ; ; ; The term parquet refers to a floor covering made of solid wood, consisting of interconnected slats in a horizontal plane. A parquet strip is the principal constructional element of the parquet. This wooden strip is obtained as a result of processing the flooring blank. In the sawmill processing of the sawlogs, the flooring blanks are sawn from the sawlogs, mostly in the radial and tangential direction. For such a purpose, sawlogs from domestic species and foreign species are used. Most dominant in this manner are the hardwood species, although softwood species can be used too. Among the domestic species, the most are beech, oak, acacia, elm, ash, and from the softwood species pine and larch. The paper focuses on the maximum quantitative yield of beech and oak sawlogs intended for processing into parquet blanks. The sawing was conducted on a bandsaw. The blanks were with a thickness of 25,0 mm. The sawlogs belonged to the I, II, and III quality classes. A total of 12 sawlogs were processed, 6 from beech (Fagus sylvatica L.) and 6 from oak (Quercus robur). All sawlogs were with a constant length of 3,0 m. The mean diameter for beech and oak sawlogs was in the range of 34,0 to 36,0 cm. The average value for the quantitative yield for beech sawlogs from I, II, and III quality classes was 37,90%. For the oak sawlogs from I, II, and III quality classes the average value of the quantitative yield was 39,40%. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Comparative analysis of yield distribution in first and second-class quality fir and spruce sawlogs (Abies alba Mill./Picea abies L.): A case study from North Macedonia(Faculty of Design and Technologies of Furniture and Interior - Skopje, 2024-12)The efficient utilisation of sawlogs represents a crucial determinant for the operational success of sawmill capacities. Sawlogs serve as the primary raw material in sawmill operations, and their rational use is influenced by several production-related factors. Key determinants impacting sawlog utilisation include wood species, log quality classification, technological capacity of sawmills, and workforce proficiency, among others. Of particular importance to sawlog processing methods are wood species and quality classification. A principal indicator of sawmill performance lies in the quantitative yield of raw material, defined by the volume of lumber produced from log processing. The economic viability of sawmills is grounded in this quantitative utilisation, with wood species and quality classification exerting the most substantial influence. This paper presents findings from a comparative analysis conducted at a sawmill facility in Berovo, Republic of North Macedonia. It examines the yield from fir/spruce (Abies alba Mill./Picea abies L.) sawlogs of both first- and second-quality classes. The analysed logs maintain a consistent length of 4.0 meters. The average diameter for first-class logs ranges from 27.0 to 57.0 cm, while for second-class logs, it spans 38.0 to 62.0 cm. The mean yield rate for first-class logs is 68.93%, and for second-class logs, it is 61.55%. A comparative analysis is provided for the coarse and fine waste generated from log processing for both quality classes. Sawing was conducted using a horizontal band saw, and the resulting lumber is designated for construction and structural purposes. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Analysis of diameter taper in fir (Abies alba Mill.) and spruce (Picea abies L.) sawlogs from 1st and 2nd quality class(FACULTY OF FOREST INDUSTRY – UNIVERSITY OF FORESTRY – SOFIA, 2025-01)The success of sawmill capacities mainly depends on the rational use of raw materials, specifically the logs for sawing. The rational use of sawmill logs is primarily influenced by quantitative yield. The quantitative yield is a complex matter influenced by several parameters, with the main ones related to the sawmill logs. The key parameters include the diameter of the logs, their length, and the diameter taper. This study focuses on analyzing the diameter taper of fir (Abies alba Mill) and spruce (Picea abies L.) sawlogs from 1st and 2nd quality class. Taper, which represents the gradual reduction in log diameter from the base to the top. By examining 80 selected logs from the sawmill company in Berovo, Republic of North Macedonia, this study identifies patterns in taper rates across eight diameter groups. The results show the impact of taper on log utilization, highlighting the implications for sawing efficiency and wood quality.
