Youngtherm Glass Wool Base is a high performance thermal and acoustic insulation solution designed for flat roof ceiling systems. It provides reliable thermal resistance, effective sound absorption, fire safety compliance and long term durability across a wide range of building applications.

Manufactured from lightweight glass wool fibres bonded with a non combustible binder, Youngtherm® Glass Wool supports energy efficient buildings while improving indoor comfort and fire performance.

The insulation is suitable for residential, commercial and light industrial buildings, particularly in structures with large roof spans or flat roof ceiling systems where both thermal control and acoustic performance are required.

​BENEFITS:

Youngtherm® Glass Wool Base insulation offers several performance advantages that support efficient building design.

• Excellent thermal insulation performance
• Effective acoustic absorption for improved indoor comfort
• Non-combustible material with certified fire performance
• Lightweight and flexible for easy handling and installation
• Moisture-resistant and non-hygroscopic
• Does not support mould, bacteria or vermin growth
• Chemically inert and odourless
• Compatible with common building materials and will not corrode metals
• Manufactured in accordance with ISO 9001:2015 quality management standards
• Produced in line with ISO 14001 environmental management standards

THERMAL AND ACOUSTIC PERFORMANCE

Youngtherm® Glass Wool insulation improves the energy performance of buildings by reducing heat transfer through roof assemblies.

The insulation layer provides conductive thermal resistance which limits heat gain during hot weather and reduces heat loss during colder periods. This contributes to improved energy efficiency and more stable indoor temperatures.

In addition to thermal performance, the glass wool structure provides effective sound absorption. This improves acoustic comfort in large open interior spaces such as offices, warehouses and industrial buildings where noise control is important.

Thermal conductivity (k-value):

0.039 W/m·K

FIRE PERFORMANCE

Youngtherm® Glass Wool is classified as a non combustible insulation material and complies with recognised fire performance standards, including:

• A1-s1,d0 non combustible classification
• SANS 53501-1 fire performance requirements

These fire performance characteristics allow the insulation to be used in both single level and multi level buildings where compliance with fire safety standards is required.

APPLICATIONS:

Youngtherm® Glass Wool Base insulation is suitable for a variety of building types and insulation applications, including:

• ​ Flat roof ceiling systems in residential buildings
• Commercial office buildings
• Light industrial facilities and warehouses
• Retrofit ceiling insulation upgrades
• New building ceiling insulation installations

The product performs particularly well in large span buildings where improved acoustic absorption and thermal performance are required.

​INSTALLATION:

Typical installation steps include:

• Measure the spacing between roof trusses
• Cut the insulation to size while still in the packaging
• Roll the insulation between the roof trusses
• Lay insulation beneath electrical wiring where required
• Cut neatly around downlights and ceiling fittings
• Use off cuts to wrap exposed piping if required 

Correct installation ensures optimal thermal and acoustic performance.
