The boss apartment in London will be ready by 2008. In cold country most windows in their house are fixed with double glazing to keep the heat in the house when the temperature is very low. I am sure boss would want to have a double glazing window as to keep their precious daughters warm during winter.
I will recommend him to go to Anglian as they have been established for more than thirty six years and has been renowned amongst UK homeowners as the place to go for high quality Home improvements. Their windows are custom-built and come with a 10-year guarantee as standard. They are also constantly improved their design and technology. With their energy-saving Ultra 2 design, it helps you reduce your energy costs, and your impact on the environment. Environment friendly too ya. :) Besides windows, they also do doors, garage, rooftrims, kitchen and everything that got to do with home improvements.
