Thermal Enclosure: Efficient Walls and Airtightness

The thermal enclosure must effectively separate the indoor environment from the outdoor environment. Thorough separation requires high-performance assemblies that control the movement of heat, air, moisture and vapor, including insulating layers that maintain or improve the assembly’s structural, air-, moisture-, and vapor-control properties. Thermal

Glazing and Cooling

Glazing and Cooling UPVC Triple Glazing Cross Section Windows always provide more than one function: light, air, views. They also affect heating and cooling loads through several heat transfer mechanisms. When choosing windows to reduce cooling loads, the goal is to control conduction and solar heat gain. Conduction is the transfer of heat
