ECO4 Services
Improving energy efficiency is one of the best investments you can make for your home or business. We provide specialized energy-saving solutions designed to reduce heat loss, lower energy bills, and create a more comfortable living environment. Our ECO4 energy efficiency services include roof & loft insulation, energy-efficient rendering, and damp-proofing, all aimed at improving thermal performance, preventing heat loss, and protecting your property from moisture damage.
Reduce Heat Loss with Professional Internal and External Insulation
Wall insulation is one of the most effective ways to retain heat, reduce energy consumption, and enhance indoor comfort. Up to 35% of a home’s heat loss occurs through uninsulated walls, making proper insulation essential for energy efficiency. We offer both internal and external insulation solutions, tailored to the structure and needs of your property.
Process
- Property Assessment – We determine whether cavity wall insulation, external wall insulation, or internal wall insulation is the best option.
- Material Selection – We use high-performance materials such as EPS boards, mineral wool, or insulated plasterboard to maximize efficiency.
- Installation
- Internal Insulation – A layer of insulated plasterboard is fixed to the internal walls, followed by finishing and decoration.
- External Insulation – Insulation boards are applied to the outside walls, covered with a weather-resistant render.
- Sealing & Finishing – Joints are sealed, and surfaces are smoothed to ensure durability and an attractive finish.
Benefits
- Reduces heat loss, keeping your home warmer.
- Lowers heating costs and energy bills.
- Improves soundproofing for a quieter living space.
- Protects walls from damp and condensation issues.
Keep Your Home Warmer in Winter and Cooler in Summer
Overview
Roof and loft insulation is one of the most effective ways to enhance your home’s energy efficiency. Up to 25% of heat loss occurs through the roof of an uninsulated property, leading to higher energy bills and an uncomfortable indoor climate. Proper insulation traps warmth in winter and keeps excess heat out in summer, maintaining a stable and comfortable temperature all year round.
Process
- Assessment & Inspection – We evaluate the existing insulation (if any) and identify areas that need improvement.
- Material Selection – Depending on the property’s needs, we use high-performance materials such as fiberglass, mineral wool, or spray foam insulation.
- Installation – Insulation is carefully laid between and over joists in lofts or within roof structures to create a continuous thermal barrier.
- Final Checks & Sealing – We ensure there are no gaps, compressions, or thermal bridges that could reduce effectiveness.
Benefits
- Reduces heat loss and lowers energy bills.
- Improves indoor comfort by maintaining a stable temperature.
- Helps prevent dampness and condensation issues.
- Increases property value and sustainability.
Protective, Insulated Finishes for Long-Term Savings
Overview
Energy-efficient rendering is a modern insulation technique that improves the thermal performance of external walls while protecting the property from harsh weather conditions. By applying a layer of insulated render, homes can retain heat more effectively, reducing energy consumption and creating a more sustainable living environment.
Process
- Surface Preparation – The exterior walls are cleaned, and any cracks or damage are repaired.
- Insulation Layer Application – High-performance insulation boards (such as EPS or mineral wool) are securely fixed to the walls.
- Base Coat & Reinforcement – A strong base coat is applied, reinforced with mesh to prevent cracks and movement.
- Final Render Finish – A breathable, weather-resistant topcoat (such as silicone, acrylic, or monocouche render) is applied for durability and style.
Benefits
- Reduces heat loss, keeping interiors warmer in winter and cooler in summer.
- Provides a durable, weather-resistant exterior.
- Enhances the aesthetic appeal of the property.
- Helps lower heating costs and carbon footprint.
Prevent Moisture Issues and Improve Indoor Air Quality
Overview
Damp-proofing is essential for protecting your home against moisture-related issues such as mold, mildew, and structural decay. Excess moisture can lead to poor indoor air quality, health risks, and long-term damage to walls, ceilings, and floors. Our professional damp-proofing solutions provide long-lasting protection against water ingress, keeping your home dry and comfortable.
Process
- Inspection & Diagnosis – We conduct a detailed survey to identify rising damp, penetrating damp, or condensation issues.
- Damp-Proofing Treatment – Depending on the severity and cause, we apply damp-proof membranes, chemical injections, or waterproof coatings to affected areas.
- Ventilation & Moisture Control – Improving air circulation with ventilation systems or dehumidifiers to prevent future damp issues.
- Final Repairs & Finishing – Damaged plaster, paint, or flooring is repaired or replaced for a fresh, clean look.
Benefits
- Prevents mold, mildew, and structural damage.
- Improves indoor air quality and prevents musty odors.
- Enhances property durability and protects long-term investments.
- Reduces energy loss caused by damp-related thermal bridging.
