FAQ Doors and Windows
What causes condensation on my windows?
The condensation on the surface facing inside your home that you can wipe off is totally different matter. Windows produce condensation whenever the dew point temperature of the air inside your home gets above the temperature of the glass surface. The dew point is proportionate to the relative humidity of the air inside the house. If the relative humidity of the air is above 80% any slightly colder than the air surface will produce condensation just like a mirror in a shower. If the relative humidity of the air is in the optimal range (35-50%) it is normal to see a bit of condensation on the windows only on the coldest days of the year. If you see excessive condensation on your new energy-efficient windows you need to check the air humidity and make sure it goes down to normal by adjusting the humidifier/heater settings and/or improving the ventilation.
Alternatively, the interior glass surface temperature of an energy-efficient window can go below normal if the flow of the warm/dry air contacting the glass is blocked by blinds or shutters – keep those open on cold days to minimize condensation. Higher-rated windows are less prone to produce condensation but even those would eventually go cold and start “sweating” if you restrict the warm air flow to them.

What is insulating glass?
Insulating glass units (IGUs) for low-rise residential homes are typically manufactured with glass in thicknesses from 3 to 6 mm (1/8″ to 1/4″). Thicker glass is used in commercial, high-rise and special applications. Laminated or tempered glass may also be used as part of the construction.
The space in between the panes provides the bulk of the insulation effect and is usually filled with a mixture of air and argon (noble gas) as it gives better insulation.
How can I improve the security of my doors?
