I have never thought it would come a day that my existing triple glazed aluminium windows and doors installed 5 years ago would need replacing in such a short time. All were ‘supposedly’ designed with commercial specification including the highest-grade aluminium alloy extrusion used and finished with the highest protection Dulux flurotec powder coated so that it would survive the hostile coastal environment for many years to come.

In short, I have nothing but problems with both corrosion problem and water leaks. The thermal insulation barrier / gaps between the triple glazed glass was poorly designed which has high heat transfer, hence it has never performed satisfactorily to achieve the optimal energy efficient windows and doors.

I have learnt a lot from this experience since then.

The challenge was to find a superior energy efficient and corrosion free product and a right installer to replace the existing triple glazed 3.6metre high x 3.8metre width double doors and windows with similar size for both downstairs and upstairs. See photos, new install.

Enertec has answered my prayer and by no means it was an easy task for the replacement. Enertec team (Leigh, Andy, Greg and Johnny) simply did a terrific job and their professionalism in carrying out the removal, rectification works and installation of the new UPVC Triple glazed windows and doors were so delightful to watch.

Though the real hot summer is not too far away, we did have few weeks of various hot and windy stormy weather days and with this opportunity, I have done some comparison on the newly install.

Having a large span of well-engineered insulated zinc roof and West facing huge size UPVC triple glazed windows and doors, I was mindful of the insulation performance and eager to monitor hourly the room temperature from morning till evening on a warm (30 C) day, the fluctuation in the room temperature was delightfully impressive within a 2-3 degree as compare to previous triple glazed aluminium windows and doors around a 7-12 degree. Just by simply touching the glass surface inside the house during a hot day, you will notice the vast different instantly.

What a difference it has made by replacing with Enertec UPVC (German made) and together with proper engineered triple glazed windows and doors, it has finally achieved what I was looking for …. superior thermal insulation and almost zero noise reduction during the extreme ‘cyclonic ‘wind directly from the bay belting hard against the windows and doors. Importantly, no water leaks detected through window or door during a stormy heavy rain fall.

Also, the benefit of using the UPVC window and door frame, the salt spray or residue left on the frame and glass is just so easy to hose it down to squeaky clean. As the products are made from UPVC, it’s no longer a corrosion concerns with any salt residue entrapment in the exposed gaps on the window or door frame.

Thank you to Rudi, Sylvia and the wonderful Enertec installation team. Highly recommended with 6 stars rating performance!! Happy day!! read less
