Topping Up Existing Insulation
Topping up the existing insulation ensures comprehensive coverage throughout your walls. Over time, the original polystyrene sheets may have settled or shifted, leaving gaps around wall ties, corners, or cracks in the existing poly board. Filling these gaps with advanced polystyrene eliminates cold spots and drafts, ensuring every part of your wall contributes to the overall insulation performance.
Using higher-grade polystyrene for insulation improvements also brings long-term benefits to your home’s value and durability. This material is designed to withstand moisture and maintain its insulating properties even in harsh conditions. Investing in this upgrade not only makes your living space more energy-efficient but also adds to the overall value of your property, making it a wise choice for homeowners looking to enhance their home’s efficiency and comfort.
How Does Cavity Wall Insulation Work?
Cavity walls consist of two layers of brick with a gap (or cavity) between them. We fill this cavity with a high-performance insulation material – Energystore superbead system, which is an injected expanded polstyrene (EPS) bead bonded with an adhesive which traps heat inside your home and prevents it from escaping.
