Front doors should be soundproof and thermally insulated. Choosing a new and efficient entry door to your home is a good investment, as it can reduce the cost of heating and cooling your home. If you have a new home under construction, you should think about buying the most efficient doors, and then consider replacement windows Denver dealers sell as soon as you can.
It is very difficult for a door to match the performance of an exterior wall, in terms of thermal insulation, but it is recommended to ensure that the door meets some essential requirements in this regard. The thermal insulation capacity of a front door depends on the materials from which it is made, the way of sealing the contact areas and the quality of the installation.
In general, regardless of the materials it is made from, a front door has a specific coefficient of thermal transfer (U), which can be between 1.4 W/ mpK and 0.85 W/ mpK. The lower the coefficient value, the better the door insulation. A value of 1.4 W / mpK is average, a value of 1 is good, and a value below 1W/ mpK is very good. If the door also has glazed areas, you must be aware of the thermal insulation capacity of the insulated glass (in this case, the coefficient of heat transfer varies between 2.9 W/ mpK and 0.5 W/ mpK).
A simple, cheap, but less efficient solution to insulate your new front door is adding special weather strips along all four sides of the interior side of the door and filling gaps along its edges using adhesive foam.
