Services
External Wall Insulation
External wall insulation improves thermal efficiency by up to 70%, reducing heating bills and carbon emissions. Ideal for solid-wall properties, it acts as a 'tea cosy' to retain heat while preventing cold bridging. Our systems use wood fibre or graphite EPS materials, providing durable, weatherproof finishes that enhance property aesthetics and value.
Passivhaus New Build
Passivhaus new builds achieve 90% energy savings through super-insulation, triple glazing, and heat recovery systems. We combine timber frames with advanced insulation to create airtight, comfortable homes that meet rigorous sustainability standards. These properties require minimal heating, significantly lowering long-term energy costs.
Warm Roof Systems
Warm roof systems prevent heat loss through rafters using wood fibre insulation, maintaining stable indoor temperatures year-round. Installed beneath roof tiles, they reduce summer overheating and winter heat loss. This method improves energy efficiency while preserving loft space usability for storage or conversion projects.
Whole House Retrofit
Whole house retrofits integrate floor, wall, and loft insulation with energy-efficient windows to create cohesive, low-carbon homes. We address moisture management and ventilation to ensure healthy living environments. These upgrades can reduce energy bills by up to 50% while increasing property comfort and market value.
Internal Wall Insulation
Internal wall insulation suits conservation areas or period properties where external work isn't feasible. Our breathable systems prevent condensation issues while improving thermal performance. This method maintains exterior aesthetics and requires minimal internal space reduction, making it ideal for historic buildings needing modern efficiency.
