A thermal break refers to an insulating material or technique used to interrupt the flow of heat between two surfaces that have different temperatures. While a thermal break itself does not directly eliminate condensation and mould, it can help reduce the likelihood of their occurrence by addressing temperature differentials and moisture control. Here’s how it works:
- Temperature Regulation: TekTherm™ Thermal Breaks help to minimize the transfer of heat from a warmer surface to a colder one. By reducing heat transfer, it helps maintain a more consistent temperature on both sides of the break. This can help prevent the formation of cold spots where condensation tends to occur.
- Dew Point Control: Condensation occurs when warm, moist air comes into contact with a surface that is at or below the dew point temperature. A Thermal Break can help minimize the temperature differential between indoor and outdoor surfaces, reducing the likelihood of condensation forming on surfaces within the building envelope.
- Insulation: Our TekTherm™ Thermal Breaks have an extremely low thermal conductivity value, which provide an additional layer of thermal resistance. This insulation helps to maintain the temperature inside the building, reducing the risk of condensation forming on cold surfaces.
- Vapor Barrier: A Thermal Break can include a vapor barrier to control the movement of moisture. The vapor barrier prevents moisture from passing through the thermal break and reaching colder surfaces where condensation can occur. By controlling moisture infiltration, it helps to reduce the conditions necessary for mould growth.
It’s important to note that while a Thermal Break can be an effective measure to reduce condensation and mould, it is typically part of a comprehensive approach to building design and construction. Proper ventilation, moisture control, and insulation throughout the building envelope are crucial factors in preventing condensation and mould issues. Consulting with an architect experienced in moisture management and thermal performance can provide specific guidance for your situation.
