This premium underfloor insulation solution provides excellent thermal and acoustic benefits, offering a safe and comfortable experience for installers and homeowners alike. Designed specifically for underfloor spaces, Retro Poly Underfloor Insulation helps to reduce heat transfer through floors, keeping indoor temperatures stable and cutting down on energy costs. Unlike traditional insulation materials, this polyester insulation is itch-free, moisture-resistant, and emits zero VOCs, ensuring a safe and clean installation process.
Retro Poly Underfloor Insulation is not only effective in enhancing indoor comfort but also environmentally responsible. Made from 80% recycled materials, this insulation is a sustainable choice for eco-conscious homeowners and builders. Polyester Solutions’ manufacturing process excludes harmful chemicals and resins, resulting in an insulation that is hypoallergenic, odorless, and free from formaldehyde binders.

Polyester Solutions Retro Poly Underfloor Insulation is available in a range of R-values to cater to different insulation needs and climate requirements. Each R-value option provides a different level of thermal resistance, allowing for customizable insulation based on the desired energy savings and indoor comfort. The available R-value options include:
These R-values offer a tailored approach to insulation, ensuring that every home can meet its unique energy efficiency needs while maintaining a comfortable indoor environment.
Retro Poly Underfloor Insulation Rolls are crafted without additional chemical or resin binders, resulting in a pure and safe insulation material. Unlike traditional glasswool products, polyester insulation has a soft, manageable texture, making installation more comfortable. For effective insulation performance, it is essential to ensure a snug fit between timber joists, as gaps as small as 1cm can significantly reduce the insulation’s effectiveness.
Each roll is produced in a standard 450mm width, suitable for most common underfloor spaces. The batts can easily be torn or cut to accommodate irregularly spaced joists, providing flexibility in application. Properly installed, Retro Poly Underfloor Insulation can reduce winter heat losses and summer heat gains by up to 20%, offering significant energy savings throughout the year. By minimizing reliance on heating and cooling systems, homeowners can reduce power bills while enjoying a more comfortable living environment.
In addition to its thermal insulation properties, Retro Poly Underfloor also provides acoustic benefits. It is a bulk insulation product that effectively reduces airborne sound transmission between floors, making it ideal for multi-story homes. The insulation dampens noise from footfall, voices, and other sounds from lower levels, creating a quieter and more peaceful indoor environment. This acoustic benefit is especially valuable in homes with high foot traffic, as well as in commercial buildings that require noise control between floors.
