ProofTherm Insulation = Breathable: For a healthier living space | Highly effective insulation

Many existing properties could benefit from better insulation. Heat loss through walls accounts for up to 33% of all domestic heat loss in UK and ROI buildings according to The Energy Savings Trust. ProofTherm effectively increases the thermal resistance of any wall, which means its ability to resist temperature change by not allowing heat to pass through it. Better insulated walls mean lower heating bills in winter and a much more comfortable living environment in summer.

A single 20mm coat of ProofTherm external wall render applied to a bare masonry wall will increase its thermal resistance by 250%.

Insulating homes with ProofTherm creates a more comfortable living environment. External walls get a fresh lease of life, giving the house an instant “lift”. Internal walls will be warmer with less trouble from damp and mould.


The insulating aggregate in ProofTherm is full of microscopic air bubbles trapped in a honeycomb-like structure. Heat can’t be conducted easily through air; it’s why we now build houses with cavity walls and why we wear down-filled jackets. By creating a continuous layer of highly aerated render/plaster across a wall, we are creating millions of micro-cavities that resist the flow of heat through the structure. Highly vapour-permeable, ProofTherm allows the structure to breathe, reducing the risk of moisture damage and mould.


ProofTherm uses expanded Perlite as an insulating aggregate to create a highly breathable, lightweight, insulating render/ plaster that can be used to provide significant gains in thermal and acoustic insulation on internal and external walls. The open cell, honeycomb structure of the expanded Perlite creates a thermally resistant barrier that reduces heat and sound transmission through the wall when applied as an external render or an internal plaster.

“A practical and affordable insulation solution that allows buildings to breathe, reducing the problems and damage caused by damp.”

Because it is highly vapour-permeable, ProofTherm allows the structure to breathe, reducing the risk of moisture damage and mould. ProofTherm is suitable for use on external walls, and internal walls and is also available as an insulating floor screed.

📢SMET is Delighted to announce its certification to BES 6001!♻
Well done to the dynamic duo – Colette Hood and Joris Smet!! Pictured here with BSI Client Manager, Mairead Magennis.

The key objectives of the standard are:
✔ To promote responsible sourcing of products
✔ To give clear guidance on the sustainability aspects that should be addressed
✔ To provide confidence that materials and products are being responsibly sourced

The benefits are:
✔ Demonstrating to stakeholders that SMET sources products responsibly
✔ SMET can make more informed decisions when selecting suppliers
✔ SMET improves its overall social and environmental performance

Why is this important?

Responsible sourcing is becoming increasingly important when procuring materials for construction. Standards such as BES 6001 (responsible sourcing of construction products) are increasingly specified on major projects. The BRE developed the BES 6001 Framework Standard for Responsible Sourcing. It is an independent stakeholder-supported, third-party scheme that enables manufacturers to have the responsible sourcing credentials of a wide range of materials assessed and certificated.

Responsible Sourcing of Construction Products provides a holistic approach to managing a product from the point at which component materials are mined or harvested, through manufacture and processing.

Responsible Sourcing of Construction Products is demonstrated through an ethos of supply chain management and product stewardship and encompasses social, economic, and environmental dimensions.

Responsible Sourcing of Construction Products addresses aspects such as stakeholder engagement, labour practices, and the management of supply chains serving materials sectors upstream of the manufacturer.

What is BES 6001?

Framework Standard for Responsible Sourcing

BES 6001 – The Framework Standard for Responsible Sourcing – see the Green Book Live Responsible Sourcing of Construction Products page to access the standard and related information.

The standard sets out requirements under 3 main headings:

  • Organisational management
  • Supply chain management
  • Environmental and social issues

BES 6001 Certification gives manufacturers the opportunity to:

  • Differentiate their products against competitors
  • Demonstrate corporate reputation and leadership
  • Benchmark their manufacturing performance and facilitate continuous improvement through certification

And specifiers and purchasers the benefit of:

  • Securing additional BREEAM credits for their buildings
  • Reducing risk down the supply chain
  • Demonstrating corporate reputation and leadership.

Read how our two main German suppliers for screed, render, and tiling are doing in their commitments to the environment and sustainability:

Sustainability is very important to CASEA and it is implemented at all levels – from the supply of raw materials and logistics to production and recycling. Regional focus on quarries in different parts of Germany also contributes to sustainability because it avoids unnecessary climate-damaging transport routes.   Read More:
