External Wall Insulation For Housing Refurbishment

Product catalog summary
Overview
The document focuses on the application of External Wall Insulation (EWI) in housing refurbishment within the UK's Energy Companies Obligation (ECO) scheme. The UK government targets an 80% reduction in carbon emissions by 2050, with EWI being a pivotal technology for enhancing energy efficiency in existing buildings.
Energy Companies Obligation (ECO)
The ECO scheme aims to lower UK energy consumption, assist low-income households, and improve hard-to-treat solid wall properties. It operates alongside the Green Deal, funded by energy suppliers with an annual budget of approximately £1.3 billion.
Hard to Treat Homes
Approximately 7 million UK homes with single skin, solid walls require insulation. EWI is identified as the most effective solution, providing long-term thermal performance and weather protection.
Benefits of External Wall Insulation
  • Thermal Efficiency: EWI minimizes heat loss and energy consumption by reducing thermal bridging.
  • Condensation and Mould Prevention: Proper EWI installation keeps wall temperatures above the dew point, preventing dampness and mould.
  • Weather Protection: Insulated facades guard against frost and moisture damage, lowering maintenance costs.
  • Cost and Disruption Minimization: EWI installation is external, avoiding interior disruption and tenant rehousing.
Stomix Systems
Stomix, part of Sto, provides EWI systems for the ECO market, suitable for various building types:
  • StxTherm Eco: Cost-effective for large projects, ideal for low to medium rise buildings.
  • StxTherm Robust: Offers traditional finishes for areas with strict planning regulations.
  • StxTherm Protect: Designed for high-rise buildings with stringent fire protection needs.
Technical Support and Training
Sto offers extensive support, including consultancy, on-site technical advice, and contractor training to ensure quality EWI system installation.
Environmental Commitment
Sto is dedicated to environmental protection, providing recycling services for waste materials and reducing packaging use.
Render Finishes
Various render finishes are available, such as silicone and dash render, offering benefits like weather protection and aesthetic enhancement.
Decorative Profiles and Rustications
Decorative profiles and rustications enhance refurbished houses, ensuring they blend with the environment. These profiles are lightweight, weather-resistant, and easy to install, available in standard or custom designs.
Brick Slips
Brick Slips are flexible, lightweight slips made from acrylic render to mimic brickwork, allowing EWI installation while maintaining a brick facade appearance. They are durable, weather-resistant, and require minimal maintenance, available in six standard colors and mortar shades, with custom designs possible.
Detail Drawings and Thermal Bridging
The document stresses addressing thermal bridging at material interfaces like windows and doors to maintain thermal efficiency, especially below the DPC level.
System Accessories
Sto provides a complete range of EWI systems with high-quality accessories such as beads, profiles, mesh, and tracks, designed for durability and typical refurbishment conditions. Key accessories include Stomix glass fiber mesh for strength, starter tracks for a level base, stop beads for clean edges, and corner beads for reinforcement.

Energy Companies Obligation (ECO) For social housing projects. The UK Government’s target to reduce carbon emissions by 80% before 2050 is driving today’s construction policy. The majority of buildings that will be in use by 2050 are already in use today. In total, these buildings account for around 40% of the UK’s annual carbon emissions. On average, 35% of the energy used to heat our homes is lost through the external walls. Significant energy and carbon reductions can be made by refitting homes with more energy efficient technologies. External wall insulation (EWI) is one such technology,...

ECO will be funded by energy suppliers who have 3 obligations: Carbon Saving Communities Obligation 15% of suppliers’ funds are to be used to upgrade hard-to-reach, low-income households in rural communities. Affordable Warmth Obligation Provides heating and insulation measures to low-income consumers living in private tenure properties that receive particular means-tested benefits, e.g. the elderly, disabled and families. Carbon Saving Obligation Covers the installation of measures like solid wall and hard-to-treat cavity wall insulation, which ordinarily cannot be financed solely through the...

EWI systems protect the wall from rain, but remain vapour permeable so moisture can escape. 3. Protect properties from weather damage An insulated, rendered facade protects the substrate from frost and moisture damage. This significantly reduces the risk of high maintenance and repair costs. 4. Minimise costs and disruption Externally insulating will not encroach into the interior of your properties, all work is external. This removes the need for significant internal refurbishment and will not reduce interior room dimensions. There is also no need to temporarily rehouse your tenants. Such disruptions...

Local Planning Colour & Finish Visualisations. Architectural drawings or photographic images of a building can be modified to show a selection of possible colour combinations that could be applied. The colours selected, and judicial design choices as to which parts of a row of terraced houses to apply the various colour shades, can make a dramatic difference to the aesthetics of a building. The Sto colour design service is particularly helpful for refurbishment projects such as social housing. Colour combinations and where they are applied can make a building appear longer, shorter, wider, as...
