Our Insulation Services in Portsmouth

Ignite Property Group delivers practical insulation improvements that make a noticeable difference in both comfort and energy performance.

Loft Insulation in Portsmouth

Heat loss through the roof is one of the most common causes of high energy bills. Our loft insulation service ensures insulation is installed to the correct depth using durable, high-quality materials. This helps keep homes warmer during colder months and cooler in summer, potentially reducing heating costs by up to 25%.

Cavity Wall Insulation

Many Portsmouth homes built from the 1930s onwards feature cavity walls that may still be uninsulated. We install EPS bonded bead insulation, a modern and breathable solution that fills wall cavities evenly to minimise heat loss without compromising airflow. This upgrade improves thermal efficiency and indoor comfort.
