Silicone roof coatings are known for their ability to provide excellent UV, water, and weathering resistance. This can make them a great choice for many low-slope roofs.Here's a look at the strengths of silicone roof coatings and the use cases they're best suited for.
Thermal insulation is an important part of commercial roofing assemblies. The aim of this article is to examine the factors influencing the thermal resistance, known as R-value of polyiso. The prediction of long term R-value and the influence of climate, i.e. temperature, have been of significant interest over the past few decades as building energy budgets have increased in importance. Recent discussions as to what R-value the designer should use and the importance of ambient temperature are reviewed and discussed.
Metal roofs are generally known for their low maintenance, aesthetic appeal, and a finish that protects them from sun and water damage. However, after many years, that finish may fade or deteriorate. Then the building owner must decide whether to restore or replace their roof.While there are some situations when replacement is necessary, metal roof restoration may be more accessible than many people think. And restoring your customers' metal roofs instead of replacing them could lower their overall costs while saving time and labor expenses for you.
Is thermal mass a lost art form after centuries of use in temperate regions?In building design, the thermal mass of a building enables it to store heat, providing "inertia" against temperature fluctuations. It reduces the impact of external daily temperature swings on internal heating and cooling requirements. This thermal inertia has been an on-off again topic of discussion for some time. Proponents of adding thermal inertia point to Mediterranean area buildings constructed with thick stone walls and ceramic tile floors etc. Such buildings have kept occupants cooler than lighter weight buildings in many temperate areas of the world for centuries. In the quest to improve the energy efficiency of buildings, further gains are becoming increasingly harder to come by.
