Why air sealing and blown-in insulation are so important

Energy efficiency and sustainability are at the heart of modern construction. The combination of airtightness and blown-in insulation plays a crucial role in this. These two methods complement each other perfectly to minimize energy loss, reduce heating costs, and maximize living comfort.

Air sealing: The invisible protection for your home

What is air sealing?

Airtightness refers to measures that prevent uncontrolled air from entering or escaping a building from the outside. This is achieved by sealing windows, doors, and other potential weak points in the building envelope.

Advantages of air sealing

• Constant room temperature: A well-planned air seal ensures consistent temperatures and prevents unpleasant drafts.
• Protection against moisture: It prevents moisture penetration and reduces the risk of mold growth.
• Better indoor air quality: Pollutants and allergens stay outside, creating a healthier living environment.

Air sealing in winter

Effective air sealing is essential, especially during the colder months. It keeps the heat in and prevents unnecessary heating costs.

Avoiding thermal bridges

Air sealing helps minimize thermal bridges – weak points in the insulation through which heat escapes.

Blown-in insulation: Sustainable warmth for your home

What is blown-in insulation?

Blown-in insulation consists of cellulose flakes made from recycled newspaper. These flakes are blown into cavities, providing seamless insulation.

Sustainability and recycling

Because blown-in insulation is made from recycled material, it’s an environmentally friendly choice. It contributes to CO₂ reduction and conserves valuable resources. Learn more in our blog post .

Sound insulation and moisture regulation

In addition to excellent thermal protection, blown-in insulation also offers high sound insulation. It also absorbs and releases moisture, reducing the risk of mold growth.

Energy savings with blown-in insulation

By reducing heat loss, blown-in insulation significantly lowers your heating costs. It is particularly suitable for new buildings and energy-efficient renovations.

The perfect combination: air sealing and blown-in insulation

• Minimizing heat loss: A virtually airtight building envelope reduces energy losses and ensures a consistently pleasant indoor climate.
• Reduction of energy costs: Less heat loss means lower heating costs and at the same time a contribution to environmental protection.
• Improving the indoor climate: By avoiding drafts and regulating humidity, a pleasant and healthy living environment is created.
• Focus on sustainability: This combination is not only energy-efficient but also environmentally friendly. Recycled cellulose flakes and a dense building envelope improve your home’s ecological footprint.
