CavityTherm Wall Insulation: Superior Thermal Performance

Achieving optimal energy efficiency and compliance with building regulations is a critical goal for architects and contractors working on modern constructions. Insulation plays a vital role in this equation, particularly in cavity wall systems, where maintaining high thermal performance is essential. Unilin’s CavityTherm Wall Insulation has emerged as a market-leading solution, combining innovative design, precision engineering, and excellent thermal performance to meet the needs of modern building projects.

What is CavityTherm Wall Insulation?

CavityTherm is a high-performance, rigid polyisocyanurate (PIR) foam insulation board designed specifically for use in cavity walls. The product is engineered to provide thermal efficiency while maintaining the structural and functional integrity of the cavity wall.

Key Features of CavityTherm Wall Insulation:

  • Advanced Thermal Performance

CavityTherm boards deliver a lambda value as low as 0.021 W/mK, making them an exceptionally effective solution for reducing heat loss and ensuring a highly energy-efficient building envelope.

  • Integrated Features for Enhanced Installation

CavityTherm boards incorporate tongue-and-groove joints along all edges, ensuring a continuous layer of insulation while minimising thermal bridges. Additionally, each board includes pre-formed corners, providing an airtight fit that simplifies installation.

  • Moisture Resistance

CavityTherm insulation contains an engineered facing to protect against moisture, making it particularly suited for cavity wall applications and for supporting excellent building performance.

  • Wide Range of Applications

CavityTherm is appropriate for traditional masonry walls and full-fill cavity wall applications, meeting modern construction standards with ease.

Why Use CavityTherm for Cavity Walls?

CavityTherm brings numerous advantages for both residential and commercial projects, aligning with the increasing demand for sustainable and energy-efficient building practices. Below are the top reasons to choose CavityTherm for your next project:

  1. Exceptional U-values

Achieving low U-values in construction is critical for meeting building regulations such as NZEB (Nearly Zero Energy Building) standards. CavityTherm’s advanced thermal efficiency ensures that architects and contractors can easily meet or exceed these legal requirements without compromising on wall thickness or structural integrity.

  1. Enhanced Energy Efficiency

Proper insulation significantly reduces energy consumption, resulting in lower heating costs for building occupants. CavityTherm helps contractors enhance a building’s energy efficiency rating, which can also positively impact its resale and market value.

  1. Installation Made Easy

The tongue-and-groove edge profile of CavityTherm insulation boards ensures seamless interconnection, simplifying installation for contractors and helping to create a uniform insulation barrier. Typical detailing options, like pre-formed corners and lintel pieces, further speed up the process while adhering to best practices in cavity wall construction.

  1. Moisture Control and Durability

One of the common concerns with cavity walls is moisture ingress, which may lead to reduced insulation performance or even structural issues over time. The moisture-resistant properties of CavityTherm, combined with its robust closed-cell PIR core, prevent water ingress, ensure product longevity, and allow peace of mind for building professionals.

  1. Sustainability Credentials

CavityTherm is developed with sustainability in mind. Its focus on reducing energy loss contributes significantly to the carbon neutrality of new and retrofitted builds, supporting Ireland’s climate action goals.

Applications of CavityTherm Insulation

CavityTherm insulation is designed for use in full-fill cavity wall applications and is compatible with a range of construction types. Below are some of its key applications and suitability criteria:

  • Residential Buildings

From single-storey family homes to multi-storey apartment complexes, CavityTherm is an ideal solution to achieve low U-values and ensure compliance with energy efficiency standards.

  • Commercial Projects

Offices, retail buildings, and hospitality venues benefit from its high thermal performance and cost savings achieved during HVAC operation due to reduced energy demands.

  • Retrofit Projects

CavityTherm is suitable for upgrading existing masonry cavity walls, providing a straightforward and effective method to enhance thermal insulation and energy performance.
