Introducing a Window Revolution

Integrated pollen and dust filters for a healthier, greener home

Their Challenge

Champions of Innovative Window Design
WindoWeb, founded by visionary inventor and entrepreneur Lee Callender, is reshaping the world of window manufacturing. With a decade-old concept finally taking form, WindoWeb’s patent pending technology incorporates a nearly invisible filter within the window frame itself. This simple yet groundbreaking design promises to keep pollen and insects out while allowing fresh air in—improving home comfort, saving on energy use, and delivering added peace of mind for households across the globe.

The Challenge: Bringing an Idea to Life
For Lee, turning a long-held idea into a market-ready innovation required specialised design skills and clear visualisations. He needed a solution that captured the nuances of integrating a replaceable filter cartridge seamlessly into existing window frames. Without these professional 3D designs, it would be considerably harder to secure investment, engage window manufacturers, or finalise patent applications.

Arrow’s support has been invaluable and arrived just when I needed it most. Their professionalism, speed and enthusiasm helped me transform a ten-year-old concept into a tangible product. I’d recommend Arrow to anyone—there’s nothing to lose and everything to gain!

Arrow Analyses the Business Challenge

Arrow: Providing Tailored Innovation Support
Seeking practical, hands-on assistance to transform his sketches into polished 3D models, Lee approached Arrow. Recognising WindoWeb’s potential to revolutionise an established sector, Lee was connected with the Arrow team at the University of Sunderland, where Senior Innovation Associate Richard Eynon provided the technical expertise to bring WindoWeb’s concept to life.

Working Together for Real Results – Arrow’s Solution for Success

Under Arrow’s guidance and tapping into wider University support, WindoWeb rapidly progressed from a set of sketches to fully realised 3D designs. This achievement was crucial for:

  • Patent Validation: The detailed renderings provided patent lawyers with convincing evidence of how the technology operates, helping to expedite the intellectual property process.
  • Investor Engagement: With high-quality visuals ready to share, Lee can now showcase the product’s benefits to prospective investors and global window manufacturers.
  • Refinement & Development: The 3D models enabled Lee to collaborate closely with the Arrow team and academics, iterating on essential details – such as a discreet, flush-fitting pop-out handle – thus ensuring the filter remains practically invisible when the window is closed.

Arrow’s practical, business-focused approach meant Lee could secure the support he needed in a matter of weeks. By comparison, other grant applications had left him waiting for months without a decision.

Hear from our university partners

We have thoroughly enjoyed working with Lee supporting him with the development of WindoWeb through the Arrow programme. The expertise and resources at the University of Sunderland played a crucial role in transforming his vision into detailed 3D designs, which have been instrumental in securing patents and engaging investors.

The project went really well because NICD are obviously specialists at what they do and we are specialists at the technology that we work with. So, the two of us coming together was a really good combination and collaboration because we brought our skills from the app sector and they added their expertise in AI, data analysis and machine learning.
