Creating greener buildings isn’t just about renewable energy or efficient heating systems. The performance of the building itself plays a major role in how much energy is required to keep it comfortable.

The building envelope – including the external walls, roof, floors, windows and doors – separates the internal environment from the conditions outside. Improving its thermal performance can reduce heat loss, lower energy demand and help protect the building fabric.

Reducing Heat Loss Through External Walls

External walls can be a significant source of heat loss, particularly in older or poorly insulated properties.

When heat passes easily through the external walls, more energy is needed to maintain a comfortable internal temperature. Improving insulation helps slow this transfer of heat and allows the building to retain warmth for longer.

External Wall Insulation (EWI) achieves this by adding a continuous layer of insulation to the outside of the building.

As well as improving the U-value of the wall, externally applied insulation can help reduce thermal bridging by creating a more continuous thermal layer across the façade.

Why a Fabric-First Approach Matters

A fabric-first approach focuses on improving the performance of the building envelope before relying on additional technology to reduce energy consumption.

Improving insulation can reduce the amount of energy a building needs in the first place, helping heating systems operate more efficiently and creating more stable internal temperatures.

For existing buildings, this can be particularly valuable. Rather than replacing the structure, upgrading the external envelope can improve its thermal performance while retaining the existing building.

Protecting the Building Fabric

A high-performing building envelope needs to do more than retain heat.

External walls are continuously exposed to rain, wind and changing temperatures. A correctly specified EWI system combines insulation with reinforced basecoats and a protective decorative finish to create a complete external façade.

By positioning the insulation externally, the existing wall construction is also protected from some of the temperature fluctuations experienced at the outside of the building.

Careful detailing remains essential, particularly around windows, doors, rooflines, penetrations and other junctions where continuity of insulation and weather protection must be maintained.

Improving Building Performance with ProRend EIFS 

ProRend EIFS from SAS Render Systems provides an integrated external wall insulation and render solution for improving the thermal performance and appearance of suitable buildings.

The system combines external insulation with a reinforced ProRend basecoat, alkali-resistant reinforcing mesh, primer and a ProRend decorative finish.

Different insulation types and thicknesses can be specified depending on the existing construction and required thermal performance, while the range of ProRend finishes provides flexibility over the final appearance of the façade.

SAS can also provide project-specific technical support, including U-value calculations, system specifications, insulation guidance and construction details.

A Better Building Envelope for the Future

Creating greener buildings starts with reducing unnecessary energy demand.

By improving the thermal performance of external walls, reducing heat loss and protecting the underlying building fabric, External Wall Insulation can play an important role in creating more energy-efficient and resilient buildings.

For both refurbishment and suitable new-build applications, ProRend EIFS provides a complete approach to insulation and rendered façade protection, helping improve building performance while providing a high-quality external finish.

Backed by a robust 30-year BBA system durability certification and a 10-year warranty from SAS Render Systems, it emerges as the ultimate choice for decarbonisation projects, promising unparalleled protection against the elements.

Enhanced Thermal Insulation with ProRend EIFS

ProRend EIFS is engineered to provide exceptional thermal insulation by enveloping buildings in a continuous layer of insulation material, using a choice of either mineral wool for enhanced fire protection or EPS for outstanding thermal properties. This significantly reduces heat transfer through the building envelope, minimising the need for energy-intensive heating and cooling systems. By enhancing energy efficiency, ProRend EIFS helps reduce carbon emissions associated with building operations, contributing to decarbonisation goals.

Energy Efficiency and Carbon Reduction

The combination of ProRend EIFS and ProRend Colourtex offers synergistic benefits for decarbonisation. The enhanced thermal insulation provided by ProRend EIFS reduces the building’s reliance on heating and cooling systems, leading to significant energy savings and a corresponding decrease in carbon emissions. ProRend Colourtex render not only adds aesthetic appeal and a high-performance exterior finish but also provides additional weather protection and durability to the façade helping further reduce energy consumption and carbon footprint.

Long-Term Sustainability and Lifecycle Performance

ProRend EIFS contributes to long-term sustainability by minimising the need for maintenance and premature replacements. The durable finish provided by thin coat render protects the underlying insulation system, extending the lifespan of the facade and reducing carbon associated with replacement materials. This holistic approach to building design emphasises lifecycle performance and resilience, supporting decarbonisation efforts over the entire lifespan of the building.

Case Study: Cornerstone Housing Limited’s Beacon Avenue Refurbishment Project

Cornerstone Housing Limited’s Beacon Avenue refurbishment project exemplifies the efficacy of ProRend External Insulation in advancing sustainable construction. The initiative aimed to modernise existing housing while promoting sustainability, aligning with Cornerstone’s lower carbon footprint initiative.

Collaborating closely with SAS Render Systems and Heighway Field Architects, Cornerstone ensured sustainability goals were integrated from design to completion. The project entailed six construction phases, with ProRend EIFS installed to blocks of terraced houses, enhancing energy efficiency and thermal comfort.

The completion of the project in mid-2022 marked a milestone in Cornerstone’s sustainability journey. Through effective collaboration and innovative solutions, Cornerstone demonstrated the transformative potential of sustainable construction in reducing carbon emissions and enhancing housing quality, helping them reach their decarbonisation goals.
