At Longden Doors, we’re committed to providing our customers with doors that enhance their homes and contribute to a more sustainable future. Passivhaus doors are a key element in achieving both.
Minimal intervention and the retention of as much of the existing fabric as possible is vitally important to many great projects. The key is a combination of traditional craftsmanship, specialist conservation experience and an innovative, highly engineered approach to detailed design and construction.
What are Passivhaus Doors?
Passivhaus is a voluntary energy-saving standard for buildings that helps to shrink their environmental impact, focusing on creating comfortable living spaces with minimal energy use for heating and cooling.
Passivhaus doors play a crucial role in this by:
Enhancing thermal insulation:
They are designed to minimise heat transfer between the inside and outside of a building, reducing energy consumption for maintaining comfortable temperatures.
Improving air quality:
They can contribute to a tighter building envelope, which can help control air infiltration and reduce exposure to pollutants and allergens.
Lowering carbon footprint:
By minimising energy use for heating and cooling, passive doors contribute to reducing a building’s overall carbon footprint.

Legislation and Specifications
While Passivhaus is a voluntary standard, there are building regulations that focus on energy efficiency in construction.
Scotland is planning a policy for ultra energy-efficient new homes. This policy is expected to go into consultation in summer 2024 and be implemented by December 2024.

Building standards
The April 2024 technical handbooks are now published, introducing the Scottish Government’s New Build Heat Standard via standard 6.11 (Heating and hot water – direct emission heating system) and consequential changes to standard 6.1 and 7.1.
