In New Zealand, the charm of older homes often comes with a hidden drawback – a lack of proper insulation. These houses, brimming with history and character, frequently suffer from drafts, damp, and excessively cold or hot rooms, making them uncomfortable and energy inefficient. This is often due to an incomplete or deteriorated thermal envelope, a concept fundamental to maintaining a comfortable indoor temperature. In a well-insulated home, the thermal envelope is the barrier that keeps the warmth in and the cold out, or vice versa, depending on the season. In this article we explain the importance of home insulation and discuss our FREE home insulation assessment service to help ensure that your home’s thermal envelope is sealed and effective.
Heat transfer in a home refers to the process through which heat or thermal energy moves from one place to another. This can occur via three primary mechanisms: conduction, convection, and radiation.
Conduction is the process by which heat travels through solid materials, such as when the heat from your home’s interior walls permeates to the exterior walls during a cold winter day.
Convection, on the other hand, is the movement of heat through liquids or gases, and is the principle behind the warm air rising and cold air sinking in your home, creating drafts.
Lastly, radiation is the transfer of heat through electromagnetic waves, similar to how the sun’s heat radiates to the earth. In an inadequately insulated home, these forms of heat transfer can lead to substantial energy loss, as your heating system works harder to maintain a consistent and comfortable temperature inside. Therefore, proper insulation is critical in controlling heat transfer, leading to a more energy efficient home.
The thermal envelope of a home can be likened to a protective cocoon, comprising the walls, ceiling, floors, doors, and windows, all working together to resist the unwanted transfer of heat. Insulation is the key factor in this resistance, acting as a barrier to heat flow, either keeping your home warm during winter or cool during summer. A sealed and complete thermal envelope, therefore, can be the difference between a home that leaks energy (and money) and one that is energy efficient, keeping you comfortable all year round.
Though many older New Zealand homes have some insulation, it may be insufficient, not meeting today’s standards for thermal efficiency, or it may have deteriorated over time. Certain types of insulation can lose their effectiveness, creating gaps in the thermal envelope. If a home isn’t fully insulated, homeowners may experience a variety of discomforts and signs indicative of an insulation problem.
One of the most noticeable symptoms is irregular temperature variations, where some rooms feel excessively cold in the winter or hot in the summer. Drafty rooms are another common issue, with cold air seeping in through gaps and cracks during colder months. Unusually high energy bills can also be a red flag, as poor insulation causes heating and cooling systems to work overtime to maintain a comfortable indoor temperature. Moisture issues such as damp walls, mould, or mildew can also suggest insulation issues, as a well-insulated home should manage moisture effectively.
Finally, if you notice pests such as rodents or insects in your home, they could be getting in through holes or gaps left by deteriorating insulation. All these signs suggest a potential problem with your home’s insulation that should be addressed promptly.
