Our existing double glazing was over 30 years old and in need of replacing. Having seen the quality of Zenith windows and doors shown by the salesman, we decided to have our bay windows replaced (10 windows).
We were so pleased with the increase in warmth and noise insulation that we had our kitchen windows and back door replaced soon after. Again a significant improvement.
After discussions with Zenith, we decided to have our rear upstairs windows replaced - all windows are now Zenith and we are delighted with the results. Our heating bills will certainly reduce significantly!
