Beyond Aesthetics

The Environmental Benefits of Insulating Lime Plasters and Renders with Cork, Foam Glass, and Hemp-Based Materials

Introduction

Woodfibre insulation boards have emerged as a prominent player in sustainable building, offering versatile solutions for enhancing buildings’ thermal performance while minimising environmental impact.
Hempcrete

Using cork, foam glass, and hemp-based materials in insulating lime plasters and renders for internal and external solid wall applications can improve energy efficiency, comfort, and sustainability in retrofit and new construction projects.

1. Cork Insulating Lime Plasters and Renders

Expanded cork insulation boards offer an excellent solution for insulating floors. They provide thermal insulation properties that help reduce heat loss and improve building energy efficiency. When installed beneath floor finishes, these boards create a comfortable indoor environment by maintaining consistent temperatures and reducing the need for excessive heating. Cork’s natural resilience and durability make it a sustainable choice for floor insulation applications.

2. Foam Glass Insulating Lime Plasters and Renders

Foam glass, a recycled glass-based insulation material, offers an innovative, high-performance option for insulating lime plasters and renders. When incorporated into lime mixes, foam glass provides excellent thermal insulation, fire resistance, and durability. Lime plasters and renders with foam glass insulation are suitable for solid wall constructions, delivering energy savings and reducing carbon footprints in buildings.

3. Hemp-Based Insulating Lime Plasters and Renders

Hemp, a renewable and sustainable material, can also be utilised to insulate lime plasters and renders and improve thermal properties and environmental performance. Hemp fibres, combined with lime, create a breathable and mould-resistant insulation layer that contributes to a healthier indoor environment. Hemp-based lime plasters and renders offer a natural, eco-friendly option for internal and external solid wall insulation projects.

4. Internal and External Solid Wall Insulation

Insulating lime plasters and renders with cork, foam glass, or hemp-based materials provide effective internal and external solid wall insulation solutions. By enhancing the thermal performance of walls, these eco-friendly materials help regulate indoor temperatures, reduce energy consumption, and enhance occupants’ comfort.

Natural building

Insulating lime plasters and renders offer a sustainable approach to improving building envelopes, whether retrofitting existing buildings or constructing new structures.

Stephen Grindrod LTD is experienced in working with cork, foam glass, or hemp-based materials and incorporates insulating lime plasters and renders into buildings as a cost-effective and environmentally friendly approach to building insulation. By improving thermal efficiency, moisture regulation, and indoor comfort, these eco-friendly alternatives contribute to energy savings and reduce environmental impact.
