If you have ever heard of the thermal break but are not entirely sure what it means or why it is so important, we will help you understand it in a simple, practical way. At Carpintería JL Pascual, as official distributors of Finstral and Technal, we specialise in offering window and door solutions that combine design, energy efficiency and comfort for your home.
What is a thermal break?
The thermal break is a system used in aluminium or PVC windows, doors and enclosures that prevents the transfer of heat or cold between the inside and outside of the home.
Imagine your window is like a bridge: without a thermal break, heat from your home can easily “escape” through the aluminium or PVC. With a thermal break, that bridge is “interrupted” by an insulating material that significantly reduces energy loss, keeping your home warmer in winter and cooler in summer.
This system not only helps you save on your energy bill, but also improves indoor comfort and prevents condensation and damp issues.
