No matter where we reside, the issue of greenhouse gas emissions impacts us all. Their influence has a disastrous effect on earth's climate, producing global warming and many other irreversible environmental impacts, even though it is occasionally invisible to independent eye. Phase change materials (PCMs) can store release heat when abundant during day (e.g., from solar radiation), for use at night, or chilly days building needs be heated. As consequence, buildings less energy cool, which lowers emissions. Consequently, research thermally active medium-density fiberboard (MDF) with PCMs presented in this work. MDF useful interior design furniture manufacturing. The boards were created using pine (Pinus sylvestris L.) spruce (Picea abies fibers, urea-formaldehyde resin, PCM powder, phase transition temperature 22 oC, density 785 kg m−3, latent capacity 160 kJ kg−1, volumetric 126 MJ specific 2.2 kgK−1, thermal conductivity 0.18 W mK−1, maximum operating 200 °C. Five variants additive developed: 0%, 5%, 10%, 30%, 50%. According study, scores MOR, MOE, IB, Screw Withdrawal Resistance (SWR) tests decreased content was added. However, results thickness swelling water absorption indicate that particles do not exhibit substantial absorb water, retaining dimensional stability boards. panel's characteristics improved increasing concentration, according data. profiles all variations under consideration had somewhat U-shaped appearance; however, version 50% flatter form no obvious layer compaction panel surface. Therefore, certain mechanical physical manufactured panels enhanced by well-chosen addition.
