Passive Housing
Anglezarke UK specialises in supplying and installing high-performance windows, doors, and architectural glazing systems designed to meet the stringent standards required for certified Passive House buildings. We work in partnership with leading manufacturers, including Internorm and Reynaers Aluminium, to deliver precision-engineered solutions offering exceptional airtightness, low U-values, and consistent thermal performance throughout the year.
Anglezarke specialises in supplying and installing high-performance windows, doors, and glazing systems that are essential for achieving the rigorous criteria of a certified Passive House. We partner with world-leading manufacturers such as Internorm and Reynaers to offer technologically superior products that deliver airtightness, excellent U-values, and year-round thermal stability for sustainable building projects.
Passive housing represents the gold standard in energy-efficient construction, requiring minimal energy for heating and cooling. It is based on five core principles: excellent insulation, elimination of thermal bridges, superior windows and doors, heat-recovery ventilation, and exceptional airtightness.
Windows and doors are traditionally responsible for up to 25–40% of heat loss in conventional homes. In Passive House design, this weakness is eliminated through triple-glazed insulated units, thermally optimised frames, airtight installation detailing, and controlled solar gain. We provide systems designed to achieve exceptional U-values, airtightness, and overall thermal stability from leading manufacturers, such as Internorm and Reynaers.
Anglezarke UK offers bespoke consultation to help you find the ideal high-performance products for your build, from advanced triple glazing to Passivhaus-certified systems and thermally efficient rooflights, ensuring all project-specific requirements and energy performance targets are met.

What is passive housing?
Home Owner Information
Passive housing, or Passivhaus, is a rigorous, voluntary standard for energy efficiency in buildings that delivers ultra-low energy consumption for heating and cooling. It focuses on maximising heat retention and minimising energy demand through five core principles: excellent insulation, thermal-bridge-free construction, high-performance windows and doors, heat-recovery ventilation, and exceptional airtightness.
How strict are Passivhaus standards?
Architects/Builders Information
Passivhaus standards are exceptionally strict and are globally recognised as the leading, most rigorous benchmark for energy-efficient construction, requiring up to 75-90% less heating energy than conventional buildings. The three key requirements are an annual heating and cooling demand limit of 15 kWh/m² per year, exceptional airtightness demonstrated by a maximum of 0.6 air changes per hour, and a total primary energy consumption limit of 60 kWh/m² per year for all domestic uses. Certification requires meticulous design, high-quality components, and a mandatory blower door test to ensure the required airtightness is achieved.
What are the benefits of passive housing?
Home Owner Information
Passive housing can reduce energy consumption for heating and cooling by up to 90% compared to conventional buildings, resulting in significantly lower utility bills. These homes provide exceptional, year-round comfort with consistent temperatures, superior indoor air quality via ventilation systems, and a quiet, draught-free, and sustainable living environment.
