External insulation
Heat loss through your walls accounts for 35% of the total heat loss in a home. In situations where there is a solid wall or the walls are not suitable for cavity wall insulation, external insulation is an excellent alternative. External insulation is a perfect solution for new builds or refurbishment projects.
Process
External insulation involves placing a layer of expanded polystyrene (EPS) on the outer walls of the buildings. The EPS board is then reinforced with fiberglass mesh and an acrylic render is used to give an attractive finish.
Material used
We use Greenspans external insulating system. The polystyrene board is available in a range of thicknesses and has a thermal conductivity as low as 0.032W/(mk). The system is finished with an acrylic finish which is waterproof and available in a variety of textures & colours.
Results
Insulating from the outside has a clear advantage over conventional insulation techniques. By insulating from the outside and cutting thermal bridges, the entire building structure is protected from the cold and wet weather, which is not the case with internal insulation.
Advantages of external insulation
• Protects the fabric of the building.
• Improves thermal performance.
• Ensures consistent υ-values.
• Reduces thermal bridging, minimising condensation and heat loss.
• Reduces thermal stress on the structure or substrate.
• Does not reduce the size of the rooms.
• Transfers the dew-point to outside the structural wall element.
• Improves airtightness of the construction, which reduces draughts and heat loss.
• Optimises use of thermal mass, reducing internal temperature fluctations.
