Youngtherm® Polyester Ceiling Insulation is a high-performance polyester ceiling insulation solution manufactured from recycled PET fibres. Designed for the South African climate, Youngtherm improves indoor comfort by reducing heat transfer through the roof while also providing effective acoustic insulation.

As part of the Youngman Roofing & Insulation product range, Youngtherm® Polyester Ceiling Insulation helps regulate indoor temperatures year-round, supporting energy-efficient buildings. The product reduces heat gain during summer and heat loss during winter, contributing to lower energy consumption and improved thermal comfort.

Youngtherm® Polyester Ceiling Insulation is suitable for residential, commercial, and industrial buildings, including offices, schools, factories, and public infrastructure such as airports. Its durable polyester fibre construction ensures the product retains its shape and performance over time.

APPLICATIONS:

Youngtherm® Polyester Ceiling Insulation is commonly used in a range of building types where improved thermal control and acoustic comfort are required.

Typical applications include:

• ⁠ ⁠Residential homes and apartments
• Office buildings and commercial facilities
• ⁠Industrial buildings and factories
• ⁠Educational facilities such as schools and training centres
• ⁠Ceiling insulation systems in new builds and retrofit projects

​INSTALLATION:

​Youngtherm® Polyester Ceiling Insulation is installed between rafters and laid over ceiling structures to create an effective thermal barrier.

The material can easily be cut and shaped using sharp scissors or a utility knife to fit around trusses, rafters and other roof components.

When installing around downlights or light fittings, a clearance radius of approximately 100 mm should be maintained to allow for safe heat dissipation.

For best performance, insulation should always be installed in accordance with recommended building practices and applicable South African building regulations.

PURPOSE OF CEILING INSULATION

Effective ceiling insulation plays an important role in improving the energy performance of buildings. By limiting heat transfer through the roof structure, insulation helps maintain more stable indoor temperatures year-round.

Youngtherm® Polyester Ceiling Insulation reduces the demand on heating and cooling systems, helping homeowners and building owners lower electricity consumption and improve overall energy efficiency.

Over time, reduced energy usage can offset the installation cost.
