The National Self Build & Renovation Centre

At 21°, we believe you thrive in the places where you experience comfort.

Delivering a low energy or Passivhaus building is complex, and you need a solution rather than a single product.

At 21°, we are committed to using a whole house approach to provide better performing buildings from a comfort, cost and carbon perspective. We supply a range of specialist products and services, including triple glazed timber windows and doors, MVHR heat recovery ventilation, insulation and airtightness products.

We’ve worked hard to build a reputation for customer service, integrity and responsibility. We are committed to ensuring that our products are of the highest quality, backed by industry accreditations, and specified by companies at the forefront of energy-efficient construction. By choosing us you can rely on expert consultation at every step of your project.

Come to our stand to see our most energy efficient windows and doors which introduce a slimmer frame whilst maintaining dual compression seals for achieving high airtightness standards. We are also demonstrating a mechanical ventilation with heat recovery (MVHR) system and explain why good MVHR design is really important for performance.

Trust in our 30 years of experience helping people create energy efficient dream homes. Let us be part of your team, and we’ll be with you every step of the way, delivering comfort by making buildings better.
