Cavity Wall Insulation

Benefits of Cavity Wall Insulation

Cavity wall insulation is the most economical solution for lowering your heating expenses.

The cavity walls in your home typically present the largest surface area for heat loss, making proper insulation crucial. At McGaffin Mechanical, we can provide expert advice on the optimal insulation choices for your home, helping you enjoy significant benefits.

With our premium bonded bead insulation, you may notice a substantial improvement in the time it takes to heat your home, as well as how long it retains warmth after the heating is turned off.

Topping Up Existing Insulation

If your home already has polystyrene sheets installed in the cavity walls, topping them up with a more advanced, higher-grade polystyrene is a smart move. This modern insulation can potentially double your wall’s heat retention, improving energy efficiency and creating a more comfortable living environment. Enhanced insulation reduces the need for constant heating or cooling, leading to lower energy bills and a smaller carbon footprint.

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.
