Insulation We Offer

Fibreglass insulation, like Pink Batts and Bradford Gold, is made from recycled glass and provides reliable, long-lasting thermal performance. It's non-combustible, moisture-resistant, and keeps its shape over time to help maintain a warm, energy-efficient home.

Polyester insulation, including brands like Mammoth, is made from 100% polyester fibres, creating a soft, low-irritation and durable insulation option. It delivers reliable thermal performance, resists moisture, and maintains a warm, healthy and energy-efficient home.

Polystyrene insulation, such as Expol, is a rigid foam board designed to provide strong thermal performance and long-lasting stability. It's moisture-resistant, lightweight, and ideal for underfloor and wall applications where durability is essential. Polystyrene boards help keep homes warm, energy-efficient, and protected from dampness over time.
