Type 1 Passive Plus Attic Stairs

Installing an attic ladder or staircase can be a practical solution for accessing storage space or converting your attic into a functional area. However, a common challenge faced by homeowners is the potential impact on the thermal envelope of their living space. Traditional attic stairs often lead to air leakage, resulting in increased energy consumption and higher heating or cooling costs. Recognising this issue, our innovative solution comes in the form of the Type 1 Passiv Plus attic ladder.

Designed with a focus on extreme insulation and airtightness, the Type 1 Passiv Plus attic ladder is specifically tailored for Passive Houses. It addresses the fundamental problem of air leakage, allowing homeowners to access their ceiling space without compromising the airtightness and thermal envelope of their homes. This not only improves energy efficiency but also contributes significantly to maintaining a comfortable temperature within the living spaces.

Key features and benefits of the Type 1 Passiv Plus attic ladder include:

• Suitability for Passive Houses: The ladder is designed to meet the rigorous international standards of Passive Houses.
• Air tightness Class 4: Achieving a high level of air tightness, preventing air leakage, and ensuring the home’s energy efficiency is maintained.
