Environmental impact

In-line with UK environmental targets to limit & reduce emissions by 80% by 2050, our environmental business practices continually evolve to meet these with safe and secure products and services. Implementing environmentally-aware policies, all of our commercial units are specified as warm edge by utilising Swiss spacer bars. With an impressive PSI value of 0.036, they allow us to offer the best energy saving values in the world, with comfort and pleasing aesthetics as standard.

Social impact

Family run, we are dedicated to supporting our highly skilled workforce wherever possible and strive to retain high levels of happiness, positivity and motivation through various incentives, training schemes & team-building exercises. Committed to strengthening our local economy by consciously employing skilled individuals from the Cambridgeshire community, we also endeavour to run worthwhile community engagement programs e.g. fundraising events.
