Why Should You Consider Heat Shields for Thermofoil Cabinets?

Heat shields for thermofoil cabinets

Thermofoil cabinet doors are particularly susceptible to warping and damage from prolonged exposure to heat due to the unique construction of thermofoil and laminate cabinets. Thermofoil, a vinyl laminate, is heated and pressurized onto an MDF (medium-density fiberboard) core during the manufacturing process. While this results in a sleek and seamless appearance, it also renders thermofoil cabinets more vulnerable to heat-related issues compared to solid wood or other materials.

The vinyl laminate used in thermofoil cabinets has a lower heat tolerance than natural wood, making it more prone to warping, bubbling, or delamination when subjected to high temperatures. Prolonged exposure to heat, such as during the self-clean cycle of an oven, can accelerate these detrimental effects, compromising the integrity and aesthetics of thermofoil cabinet doors.

Light-colored cabinetry, including thermofoil and laminate cabinets, is particularly susceptible to heat-related damage for several reasons. Light-colored surfaces tend to absorb less heat than darker ones, resulting in less heat dissipation and potentially higher temperatures on the cabinet surface. Additionally, lighter colors may show signs of heat damage more prominently, making it crucial to implement protective measures to preserve their appearance.

Heat shields are highly recommended for all light-colored cabinetry, especially thermofoil doors, due to their effectiveness in dissipating built-up heat. These shields, typically made of thin metal, serve as a barrier between the heat source and the cabinet surface, helping to reduce the risk of warping, bubbling, or discoloration.
