Professional in Improving thermal performance & reducing heat loss

Energy Efficiency Upgrades Specialists

Poor energy efficiency is often linked to cold surfaces, uncontrolled heat loss, condensation, and increased moisture risk. Effective upgrades require understanding how insulation, ventilation, and building fabric work together. At Proofterior, all energy efficiency improvements are survey-led and evidence-based, delivered by our in-house team to improve comfort, reduce running costs, and avoid unintended moisture problems.

Our Energy Efficiency Upgrades Process

Every property performs differently, which is why our work follows a clear, structured process designed to improve efficiency without increasing moisture risk.

Survey

A detailed energy evaluation assesses insulation levels, heat loss areas, ventilation provision, and condensation risk across key property elements.

Diagnosis

Survey findings are analysed to identify thermal weaknesses, cold surfaces, and airflow issues, reviewed in line with Property Regulations and PAS guidance.

Treatment

Once confirmed, appropriate energy efficiency upgrades are carried out by our in-house team using systems suited to the property and construction type.

Protection

Preventative measures maintain ventilation and manage moisture movement to the property, supported by clear reporting and aftercare guidance.

Why Energy Efficiency Matters

Energy efficiency is not just about reducing energy bills. Poor thermal performance increases condensation risk, encourages mould growth, and places greater strain on heating systems. Upgrades carried out without understanding airflow and moisture movement can make problems worse. A correctly specified energy efficiency strategy improves comfort, stabilises internal temperatures, reduces moisture-related defects, and supports long-term building health while remaining compliant with modern regulatory standards.

Energy Evaluation

An effective energy efficiency upgrade starts with understanding how a property performs as a whole. Heat loss, ventilation, insulation, and moisture movement are closely linked, and improving one area without assessment can create unintended issues elsewhere. An energy evaluation provides a clear picture of where energy is being lost and how the building fabric responds.

Proofterior carries out a detailed energy evaluation to assess insulation levels, thermal performance, ventilation provision, and condensation risk. This includes reviewing roof spaces, internal wall surfaces, and airflow patterns to identify cold spots, heat leakage, and moisture-prone areas. Findings are assessed in line with current Building Regulations and PAS guidance to ensure upgrades are appropriate and moisture-safe.

The outcome is a clear, evidence-led understanding of the property’s performance, allowing energy efficiency improvements to be specified accurately, prioritised correctly, and delivered without increasing condensation or mould risk.

Reduce Heat Loss

Loft Insulation

Loft insulation addresses one of the most common sources of heat loss within a property. Problems arise when insulation is insufficient, unevenly installed, or degraded over time, allowing warm air to escape and cold surfaces to form below. Quick fixes such as topping up insulation without assessment fail because ventilation paths, moisture movement, and cold bridging are ignored. Proofterior assesses insulation levels, airflow, and condensation risk before specifying upgrades. Works involve installing insulation to appropriate depths, maintaining ventilation routes, and ensuring compatibility with the roof structure. The outcome is improved thermal efficiency, reduced heating demand, and lower risk of condensation-related issues.

Thermal improvement for cold walls

Isotherm Insulation Systems

Isotherm systems are designed to improve thermal performance where traditional insulation methods are unsuitable, particularly on cold internal wall surfaces prone to condensation. These issues occur when walls remain below dew point, allowing moisture to condense repeatedly. Anti-mould paints and decorative treatments fail because surface temperatures remain unchanged. Proofterior specifies Isotherm systems following assessment of wall construction, moisture behaviour, and ventilation performance. Works involve installing thermally efficient linings that improve surface temperatures while managing vapour movement. The result is warmer internal surfaces, reduced condensation risk, and improved occupant comfort.

Reduce Heat Loss

Internal Wall Insulating Paints

Internal wall insulating paints are designed to reduce surface temperature differentials and help manage condensation risk in limited situations. They are often suitable where full insulation systems are not appropriate due to space constraints or heritage considerations. These products fail when used as a standalone solution without addressing ventilation or moisture sources. Proofterior specifies insulating paints only following assessment of wall conditions, humidity levels, and airflow, and as part of a wider moisture management strategy. When used correctly, they can contribute to warmer surface temperatures and reduced condensation on treated areas.
