I work on PassivHaus and energy refurbishment. 21º have been my preferred partner for glazing, MVHR and accessories for over two decades. They are dependable, helpful and offer quality and value.
Gil Shalom
The windows were installed in 2 stages and throughout the team were helpful, supportive and efficient. The fitters were very good at minimising the disruption and worked quickly but paid attention to detail.
Jon Greenwood
Paul and the MVHR team were really responsive and helpful answering all of our queries - we did not get our MVHR system from 21 Degrees in the end as there wasn't a system to meet our specific requirements, but would definitely recommend 21 Degrees as they are very knowledgeable and helpful in MVHR design.
Elaine Ho
21 Degrees is far and away ahead of everyone else in terms of knowledge and expertise in designing and supplying MVHR systems for low energy and Passivhaus projects.
