Which Double Glazed Door Better for Reduced Heat Transfer?

Energy costs are rising by the day and if a home is not properly designed one can end up spending quite a bit on fuel bills. There are two ways one can reduce energy losses. One is by proper insulation so that heat outside cannot affect interiors in summer and, conversely, when the temperature drops, heat inside is not radiated outside. Doors and windows are main areas that are responsible for energy losses. Unlike walls that can be clad with insulation, it is not practical or aesthetic to cover doors and windows with insulation.

In such cases, the best option for doors is double glazed glass. Double glazed doors are always better than a single glazing because of the higher insulation factor. Double glazing prevents heat in the interiors from being lost to the exteriors due to the insulating air layer between the panes. This can help save a considerable amount on heating costs in winter. In summer, the opposite happens. The Sun can shine in and raise interior temperature thereby raising the load on air conditioners. Double glazing, in this case, prevents heat from affecting interiors. Convection and radiation loss is minimized by the use of right double glazed doors. The house remains warm in winter and cool in summer with minimal energy expenditure. Another benefit of double glazing is that the problem of moisture condensation simply does not arise. Still, another benefit is that of sound insulation.

Normally where glass double glazing is in use for doors one uses aluminium for structural but there is a slight disadvantage because aluminium is a good conductor of heat. Laminating aluminium with foil can help in heat conduction besides providing a pleasing, more natural look, especially when natural wood grain layering is used. Another option is double glazed uPVC frame doors that look just as good and are durable too.

Sealing is important in double glazed doors. The two glass panes must be encased in durable, weatherproof rubber to provide an air-tight seal. The door panel and how precisely it fits into the frame is another consideration that can have an impact on energy losses. Ideally, when closed, the door should fit tightly into the frame, even at the bottom to prevent passage of air. Not all door manufacturers pay attention to such minor but significant details with the result that a double glazed door that is supposed to be energy efficient does not achieve the desired levels of performance. Precision and fine tolerances, as well as sealing, are important besides aesthetics.

It is always a good idea to select a reputed manufacturer of doors and windows. Engineering and design play a crucial part indoor performance, whether it is mechanical or energy efficiency related. Precise tolerances and use of quality materials result in doors that achieve high levels of energy efficiency and ease of use besides good looks for interiors and exteriors of the building. A quality double glazed door with u PVC section frame may cost more but it will save money in the long run.
