Thermal Break Material for Aluminium Windows

thermal break material for aluminium windows

Thermal breaks are used in aluminum windows to reduce heat transfer between the interior and exterior of a building. This helps improve the energy efficiency of windows by minimizing the conduction of heat through the metal frame. There are several materials commonly used as thermal breaks in aluminum windows:  Polyurethane:  Polyamide Strips (Nylon):  Fiberglass:  Expanded … Read more

What Is a Thermal Break Strip in Aluminum Windows?

A close-up view of various black EPDM rubber gaskets and insulating thermal break strips arranged side-by-side on a light-colored wooden table for energy-efficient aluminium window frames.

Thermal break strips are small components, but they play a major role in the performance of modern aluminium windows and doors. Aluminum is strong, lightweight, and highly durable. However, it is also an excellent conductor of heat. Without a thermal break, heat can easily travel through the aluminium frame from outside to inside—and vice versa—reducing … Read more

Energy Efficiency in Windows: How Thermal Break Aluminium Cuts Heat Loss & Bills

When you’re selecting high‑performance doors and windows, you’ll often come across the term Kelvin (K) . But there’s a common misunderstanding: Kelvin is frequently mistaken for a measure of thermal performance. In reality, it serves a completely different purpose. Let’s clear up the confusion—and then focus on the numbers that actually matter for energy efficiency, … Read more

Mastering Window Sealing: Boost Energy Efficiency and Prevent Damage

A professional applying a continuous bead of white silicone sealant to the edge of an aluminum window frame to prevent air leaks and water damage.

Windows are more than just views; they are critical to your building’s thermal performance. Properly sealing or caulking your windows is one of the most cost-effective ways to lower energy bills and protect your property from structural deterioration. Why Window Sealing is Non-Negotiable Unsealed windows are a primary cause of air leaks in a home. … Read more

Water Tightness Classes for Doors and Windows

Technical illustration of a water-tight aluminum window, showing a cross-section with sealing gaskets and drainage to prevent water leakage.

What is Water Tightness? Water tightness is a measure of a window or door’s ability to prevent water penetration when subjected to specific levels of wind-driven rain. It’s not about submerging the product in water; it’s about its performance under simulated storm conditions. This performance is closely related to another key metric: wind resistance class. … Read more
