Insulation plays a critical role in modern building design, directly influencing energy efficiency, indoor comfort, and long-term operational costs. In South Africa, where temperature fluctuations can be significant, effective ceiling insulation is essential for maintaining stable indoor environments and reducing reliance on mechanical heating and cooling systems.
As energy regulations and performance expectations continue to evolve, the correct insulation specification has become a key consideration for architects, contractors, and developers.
Youngman Roofing & Insulation has introduced the Youngtherm® insulation range to address this growing need for reliable, high-performance insulation solutions tailored to South African building conditions.
This marks a shift towards a more integrated building solution, where both roofing and insulation performance can be addressed together from the outset of a project.
A COMPLETE ROOFING AND INSULATION SOLUTION
Youngman Roofing & Insulation has long been recognised as a trusted supplier of roofing materials. With the introduction of Youngtherm®, the offering now extends to include high-performance insulation solutions, enabling a more integrated approach to building envelope design.
By combining roofing and insulation systems, project teams benefit from improved compatibility, consistent product quality, and access to technical support from a single supplier.
Youngtherm® Insulation Products Are Suitable For:
- Ceiling insulation systems
- Roof liner applications
- Under-floor insulation
These solutions support both thermal insulation performance and acoustic control, depending on project requirements.
THE ROLE OF CEILING INSULATION IN BUILDING PERFORMANCE
Heat transfer through the roof is one of the primary contributors to indoor temperature variation.
Effective Ceiling Insulation Helps To:
- Reduce heat gain during summer
- Limit heat loss during winter
- Improve indoor comfort
- Lower energy consumption
- Support compliance with energy efficiency requirements
Over time, improved thermal performance contributes to reduced electricity usage and lower operating costs.
THE YOUNGTHERM® INSULATION RANGE
The Youngtherm® range currently includes polyester and glass wool insulation solutions, each designed to meet specific performance and application requirements across different building types.
YOUNGTHERM® POLYESTER CEILING INSULATION
Youngtherm® Polyester Ceiling Insulation is manufactured from thermally bonded polyester fibres derived from recycled PET materials. It is designed to provide reliable thermal and acoustic insulation while remaining safe and easy to handle during installation.
This product is well-suited to projects where ease of installation, durability, and consistent thermal performance are required.
Key Benefits
- Soft and easy to handle during installation
- Non-irritant and safe to touch
- Does not affect breathing during installation
- Tested by the South African Bureau of Standards (SABS)
- Does not contribute to flame spread and is non-toxic
- High R-values for improved thermal insulation performance
- Maintains loft and does not collapse over time
- Manufactured to ISO quality standards
Applications
Youngtherm® Polyester Ceiling Insulation is suitable for:
- Residential homes and apartments
- Commercial office buildings
- Industrial facilities and factories
- Educational facilities and public infrastructure
- New builds and retrofit insulation projects
Installation Considerations
The insulation is installed between rafters and laid over ceiling structures to create an effective thermal barrier.
It can be easily cut and shaped to fit around trusses and roof components. When installing around downlights or fittings, maintain a clearance of approximately 100mm to allow for safe heat dissipation.
Technical Specifications
The specifications below provide a general guide to product performance. Final selection should always align with project-specific requirements and applicable South African building regulations.

YOUNGTHERM® GLASS WOOL INSULATION
Youngtherm® Glass Wool Base insulation is a high-performance thermal and acoustic insulation solution designed for flat roof ceiling systems and buildings requiring improved fire performance.
Manufactured from lightweight glass wool fibres bonded with a non-combustible binder, it provides consistent insulation performance across a wide range of building applications.
Key Benefits
- Excellent thermal insulation performance
- Effective acoustic absorption
- Non-combustible material with certified fire performance
- Lightweight and flexible for easy installation
- Moisture-resistant and non-hygroscopic
- Does not support mould, bacteria, or vermin growth
- Chemically inert and odourless
- Compatible with standard building materials
