Thanks for your feedback on last weeks list of the major changes in 2015. Some additional suggestions (the ones I'll choose to print!) are :
4. The complexity of glass types and their relative R ratings (insulation) has continued to increase.
5. The type of glass you have in your house is something people talk about at parties. Glass has become more trendy!
6. Glass lites just keep getting bigger and heavier.
7. Health and Safety issues are more important and more expensive to sort than in the past (when no-one really cared)
8. Christmas seems to have come earlier this year!
