In the UK, energy bills are rising annually, and increasing energy costs are becoming the “new normal” due to ongoing geopolitical and market instability. Additionally, world leaders at the UN have highlighted the importance of achieving Net Zero, making thermal insulation a priority in building regulations.
Triple-glazing aluminium windows and doors are becoming popular in the UK due to their superior thermal and acoustic insulation compared to double and single glazing.
Durajoin triple glazed aluminium windows are an excellent choice for creating a warm and energy-efficient home. Its three glass panes enhance heat retention, ultimately leading to savings on energy bills. It helps you stay warm during winter and cool during summer with minimal heat loss in properties in London, UK.
Triple glazing is an advanced version of a double glazing unit in windows. The glazing unit is made of three separate panes of glass which are held together using two insulating gaps. The spaces between the glass panes are filled with argon gas. These insulating air gaps help to slow down the thermal transfer of cold or warmth through the unit. The bigger the gaps or depth between panes, the better the insulation.
Our Smart and Cortizo aluminium windows and doors feature Thermal Break Technology, which acts as an insulator, or in other words, as a barrier between the outside window frame and the inside frame to prevent heat transfer.
The additional glass pane of the triple glazed unit provides another barrier against freezing winter temperatures, maintaining warmer indoor conditions. As a result, there is less reliance on heating systems, cutting energy bills.
If you live in noisy areas (highways, schools, airports, high streets, etc.) in London or nearby towns, triple glazing windows are a worthy investment. They are effective in reducing outside noise from entering the home. With the right pair of glass and proper window sealing, they can significantly reduce noise compared to single and double glazed windows. If your main concern is high external noise, reach out to Durajoin’s expert consultants to explore our acoustic glazing solutions.
Increasing robberies can hinder your ability to sleep peacefully. Our aluminium windows and doors are known for their durability and strength. Compared to uPVC or composite materials, aluminium is much harder to break, which helps prevent robberies. Additionally, triple glazed doors and windows are PAS 24:2022 security approved and feature a multipoint locking system.
The additional glass pane of the triple glazed unit strengthens the window, making it more difficult to break compared to single or even double glazing. This extra layer increases the overall durability of aluminium windows.
Home buyers are often looking for homes that offer modern features and require less renovation. Triple glazing aluminium windows are energy efficient, secure, and compliant with current and future building regulations. These factors contribute to a higher resale value.
New policies are emphasizing the reduction of carbon emissions in the UK. Therefore, energy efficiency and safety are becoming priorities in current and future building regulations. Triple glazing is highly effective at reducing energy consumption, resulting in reduced carbon emissions. The improved energy efficiency of triple glazing and the security of aluminium windows will help avoid costly retrofits in the future.
