The wooden window joinery if healthy, of good quality, well-sealed and at least comprising of two layers and well maintained, provides the best heat-insulation possible.
The modern UPVC window joinery is preferable to the aluminum joinery. Whatever the choice of joinery is, it should be of high quality glass with interrupted thermal connection to reduce the condensation and to ensure minimum loss of heat during the winter season and maximum protection from the hot air during the summer season.
The outer door besides being strong and resistant to attempts for breaking, should also be very well heat insulated and sound insulated, and should further meet the interior design of the premises and the common areas of the building.
The interior doors should also be selected according to the style of the premises and should further have proper kind of insulation and seals to prevent a flow of air in the internal spaces.
The construction of the interior doors should be lighter compared to the construction of the external doors.
The materials used should be thinner, but the goal is to retain their most important features - thermal insulation and sound insulation.
When appropriate selection is done, the new window joinery and doors shall increase the comfort of the occupants of the premises, while the image of the external and internal spaces will become fresh and better.
