Insulation despite extremely narrow cavities

The existing cavity in the façade was exceptionally narrow, measuring only 1.5–2.5 cm. Conventional blow-in insulation materials are typically approved only from cavity widths of around 4 cm and would not have been suitable.

 

Insute 25-pro, however, can be used from widths of 1 cm. The material distributes evenly within the masonry, reliably fills even the narrowest areas, and ensures safe and efficient cavity insulation without any change to the façade appearance.

 

 

The more economical alternative to complex measures

The only alternative would have been removing the outer wall layer and installing an external insulation system (ETICS). This solution would have been significantly more expensive and would have required major changes to the building’s appearance, including repositioning windows and altering light conditions.

 

By using Insute 25-pro, the insulation was implemented economically, with minimal impact on the building structure and without affecting its visual appearance.

 

 

Technically precise execution with verifiable results

A total of 18 m³ of material was injected through drill holes at joint intersections (where vertical and horizontal joints meet). Spacing ranged from 80–100 cm, closer in the base area and up to 2 m in wider wall sections.

 

An energy consultant confirmed the high quality of distribution using thermography: even in critical areas, the temperature difference was only around 2 °C - an indicator of homogeneous and complete filling.

 

The scaffolding used by the window installers could be utilized, as the insulation was part of a larger modernisation project.

• Thermal conductivity of just 0.028 W/(m·K) – high insulation performance even at low thicknesses
• Permanently water-repellent yet vapour-permeable
• High thermal storage capacity – significantly higher than that of conventional insulation materials
• Excellent sound-absorbing properties

The project impressively demonstrates how Insute 25-pro enables optimal, safe and cost-effective cavity wall insulation even under extreme conditions – thereby making a significant contribution to energy efficiency and quality of life.

 

 

Utilizing the energetic potential of unused air layers

An uninsulated exterior wall is one of the main causes of high energy loss in older buildings. Especially in properties with double-leaf masonry, valuable heating energy escapes unused through the cavity. Retrofitting cavity wall insulation offers a highly efficient way to drastically reduce this heat loss.

 

In this proven method, loose insulation material is blown directly into the air layer between the two walls through small openings. The implementation does not require the erection of scaffolding and hardly affects your everyday life during the short construction phase. Within a single day, the energy-efficient retrofitting is completed, and you immediately benefit from comfortable temperatures in the house.

 

 

Material requirements for permanent insulation

For cavity wall insulation to develop its full effect over the long term, the right insulation material is crucial. The material must remain dimensionally stable over the long term, must not settle over the years, and must be resistant to moisture. Modern high-performance insulation materials like Insute effortlessly exceed these requirements.

 

Due to their extremely fine structure and excellent flowability, the particles slide even into very narrow cavities of less than four centimeters. They perfectly enclose obstacles such as wall ties or mortar residues and form a continuous insulation layer. Since the material is hydrophobic, it consistently blocks the penetration of moisture from the outside.

 

 

Securing cost-effectiveness and government subsidies

Die finanziellen Vorteile dieser Sanierungsmaßnahme überzeugen ab dem ersten Monat. Durch die deutliche Reduzierung des Energieverbrauchs sinken Ihre Heizkosten spürbar, was zu einer schnellen Amortisation der überschaubaren Kosten führt. Da das Verfahren den gesetzlichen Vorgaben zur Energieeinsparung entspricht, stehen Ihnen zudem attraktive Fördermittel von KfW oder BAFA zur Verfügung.

 

These grants significantly reduce your own investment once again. In addition to the financial savings, you make an important contribution to global climate protection through reduced CO2 emissions. At the same time, the measure protects the building fabric of your property from weather conditions and sustainably increases the overall value of the building.
