Harwich Glazing Testimonials

Customer Name: Mrs P M Booke.
I rang and spoke to a very pleasant gentleman who was extremely helpful and gave me information, cost and the main thing, when someone would come to see me. True to everything he said a very nice young man turned up within the time slot. His name was Robert Thompson he was extremely caring and he knew straight away what was wrong. Upon leaving he gave me his phone number and told me to contact him if need be. Needless to say I have not had to ring him because he seems to have done the right thing on it. It was a pleasure to have such a good workman in the house so polite etc. You have a very caring company and long may you continue.

Example Of Our Glass Services

Toughened Glass
There are two types of Toughened glass; heat-treated and chemically treated. There are then two further types of heat-treated glass; heat-strengthened, and fully-tempered. Fully-tempered heats the glass to above its annealing point, and then rapidly cools the glass. This makes it approximately four to six times tougher than standard float glass, enabling it to qualify as a safety glass that conforms to BS 6206 Class A.

Heat-strengthened follows a similar process, but is only twice as tough, and does not qualify as a safety glass. Chemical toughening involves running the glass through a bath of molten potassium nitrate, which exchanges the smaller sodium ions in the glass, with the bigger potassium ions in the molten bath.

The advantages of this are two-fold; the glass is tougher than when heat treated, and this approach can be applied to glass of complex shapes and sizes, making it suitable not just for glass sheets, but also for glass ornaments, and glass of unusual sizes.
