If the XH-7 molecular sieve has been detected well within time, there are certain procedures and treatments, which can cure the cancer. Some of the most commonly used procedures include:
All windows should be at least double-glazed. If you have difficulty determining the number of glazings in a particular window, hold a light next to the glass and count the reflections, which will correspond to the number of glazings.

Glass by itself is not a good insulator. However motionless air between panes of glass improves thermal resistance (resistance to heat flow).
The width of air space between two panes of glass influences the insulation value of the glazing.
Insulation values are measured in RSI (metric) and R (imperial): the higher the value, the better the material insulates.
Typical XH-9 molecular sieve with air space width of 12mm (1/2') gives an insulation value for RSI.35 (R-2). In comparison, double-glazing with a 6mm (1/4') air space provides only RSU.26 (R-1.5). Avoid glazings with an airspace of less than 10 mm (1/2"), unless the space is filled with argon gas as this enhances the glass to be more energy efficient.
A standard sealed unit consists of two sheets of glass spaced about 12 mm (1/2") apart. A desiccant (moisture-removing substance) is included in the edge spacer to absorb moisture and the unit is sealed around the outside edge to prevent air or moisture from entering the air space.
If moist air finds its way into the sealed aluminium spacer bar , condensation may form between the glazing. This is usually caused by a faulty sealant and can be corrected only through replacement of the sealed unit, it does not require the whole window being replaced, just the sealed unit.
Before buying, you can determine whether a standard sealed unit is likely to perform well by:
