Many homeowners in Tallinn and across Estonia face an unexpected issue during winter: their windows are new, yet cold air drafts, discomfort, or condensation appear. In most cases, the problem is not the windows themselves.
Incorrect installation
Even high-quality PVC windows can lose their insulating performance if installed improperly. Common issues include thermal bridges, poor sealing between the wall and the frame, and incorrectly applied insulation foam. These problems become especially noticeable during cold weather.
Unadjusted hardware
New windows require professional adjustment after installation. If the sash does not press tightly against the frame, cold air can enter the room. Many people are unaware that windows have seasonal adjustment settings designed to improve insulation in winter.
Wrong glass unit for the climate
Sometimes the issue lies in the choice of glazing. A glass unit with insufficient thermal performance may not be suitable for Estonia’s cold winters, leading to heat loss even if the window is technically new.
Damaged or poorly installed seals
Seals can be damaged during transport or installed incorrectly. This results in drafts and heat loss, especially during windy conditions.
What can be fixed without replacing the window?
– Professional window adjustment
– Seal inspection and replacement
– Additional insulation of installation joints
– Correction of installation defects
Conclusion:
If your new windows feel cold, replacement is rarely the first solution. In most cases, proper adjustment and maintenance can restore comfort and energy efficiency at a much lower cost.
