When planning new builds, it is essential to consider the overall architectural design and how it integrates with insulation strategies. The orientation of the building can influence energy efficiency significantly, as windows, eaves, and external shading should be optimised to reduce heat loss without compromising natural light. Additionally, the junctions between different building elements must be carefully designed to minimise potential thermal bridges. This can involve using thermal break materials in places where different construction types meet, ensuring a continuous layer of insulation throughout the structure.
Attention to the construction method is equally important in new builds. Selecting materials that offer good thermal performance can enhance the efficiency of the insulation used. For cavity walls, the width of the cavity plays a fundamental role in minimising thermal bridging, so careful calculations are necessary to determine the ideal cavity size. Furthermore, incorporating advanced technologies such as thermal imaging during the design phase can help identify risk areas that may lead to heat loss, allowing designers to address these issues proactively.
Insulation Materials and Their Role
Different insulation materials contribute uniquely to the effectiveness of cavity wall construction. Materials such as expanded polystyrene (EPS), extruded polystyrene (XPS), mineral wool, and spray foam each possess distinct thermal resistance properties. The choice of insulation affects not only the wall's performance but also the overall energy efficiency of the building. Selecting a material with a high thermal conductivity rating can help minimise heat loss and improve comfort levels within the interior spaces.
In addition to thermal performance, factors such as moisture resistance and fire safety play a crucial role in material selection. Cavity walls are particularly susceptible to moisture ingress, making it essential to choose materials that can withstand damp conditions without degrading. Compliance with fire regulations is another cons
