The presence of mold and poor insulation are often linked: cold air meets warm air (dew point) and creates condensation, the main source of humidity problems and heat loss.
Our company offers a comprehensive approach to ensure a healthy, energy-efficient, and sustainable environment for your home or building.
1. Mold Expertise and Treatment
Mold (fungi, dry rot, efflorescence) is not only unsightly; it can be harmful to health (allergies, respiratory problems) and dangerous to the building structure.
A. Our Complete Damp Diagnosis
Before any treatment, we identify the source of the problem:
- Infiltration: Roof leak, poor waterproofing of walls or facades.
- Rising Damp: Moisture originating from the ground and rising into the walls (often visible on the ground floor).
- Condensation: Lack of ventilation and poor insulation creating cold spots.
B. Treatment and Remediation Solutions
We apply targeted solutions to permanently eliminate sources of moisture and their consequences:
- Rising Damp Treatment: Injection of water-repellent products into the walls (waterproof barrier) or exterior drainage.
- Ventilation Improvement: Installation or replacement of MVHR (Mechanical Ventilation with Heat Recovery) and VMI (Mechanical Ventilation by Positive Pressure) systems to renew the air and remove ambient humidity.
- Fungicide Treatment: Application of professional products to destroy mold and prevent its reappearance after drying.
- Waterproofing Restoration: Repair of cracks, repointing of joints, and application of exterior waterproofing coatings.
2. Thermal Insulation: Energy Performance and Comfort
Once humidity is controlled, insulation becomes the barrier against heat loss, ensuring a comfortable temperature in both winter and summer, while drastically reducing your heating bills.
A. Exterior Insulation (EWI)
- EWI is the most effective solution, ideal for renovating facades or older buildings.
- Principle: Application of a continuous insulating layer to the exterior walls.
- Advantages: Eliminates almost all thermal bridges, preserves interior space, improves the building’s thermal inertia, and rejuvenates the facade’s appearance.
B. Interior Insulation (ITI)
An effective solution when exterior insulation (EWI) is not possible (due to urban planning regulations or technical constraints).
- Walls: Installation of insulating linings (mineral wool, polyurethane, eco-friendly insulation) with a vapor barrier.
- Attics and Roofs: Insulation of uninsulated attics (blown-in insulation) or converted attics (installation of rigid or semi-rigid panels).
- Floors and Ground Floors: Insulation to eliminate the feeling of cold on the floor and reduce heat loss.
C. Material Selection
We select the most suitable insulation for your project, taking into account thermal performance (R-value), acoustics, and environmental impact:
- Mineral wool (Glass, Rock): Excellent performance/price ratio.
- Synthetic insulation (Polyurethane, Polystyrene): High insulating capacity for a thin profile.
- Bio-based insulation (Wood fiber, Hemp): An environmentally friendly choice with good moisture regulation.
By choosing our expertise, you benefit from a team that understands the complex interactions between the building envelope, humidity, and energy performance.
We also assist you in studying available aid and subsidies (energy renovation bonus, local tax credits) to reduce the cost of your insulation work.
