WebbWhen a pitched roof space is created, occupants of loft living spaces are often exposed to high levels of external noise too, such as air traffic. This means that treating the roof acoustically is just as important. With effective insulation, a roof area can become a comfortable living space. WebbOne of the most commonly used, and widely recognised, acronyms in construction is VCL, which stands for vapour control layer. A VCL is a critical building component designed to protect the building from potential degradation (or poor performance) by managing the passage of water vapour within a building structure. how many joules are there in 83.9 cal
