The 7 Performance Features To Know
Triple glazed
Although this component isn’t aluminium focused, it’s still one to note down. Both Ali FOLD and PURe® doors can be manufactured with a double or triple glazed finish. The triple-glazed finish has an impressive thickness of 50mmm – enhancing thermal and acoustic insulation levels. Both glazing options differ in price, so check with your manufacturer for more details.
Long Service Value
Service value is without a doubt one of the most important performance indicators. After all, you need to know and understand how long your bi-fold doors will last and provide optimal performance.
With Ali FOLD and PURe® doors, there’s no need to worry. Long after installation, both door suites have a life expectancy in excess of 40 years. This is impressive, especially for those looking for robust, durable and sleek bi-fold door options. You need to inform your clients that aluminium bi-fold doors are a long-term investment.
Polyamide Thermal Barrier
Although both bi-fold door ranges offer incredible levels of thermal efficiency, PURe® doors deliver exceptionally high levels. PURe® utilise an integrated thermal break manufactured from expanded polyurethane (PUR) which allows ultra-low U values to be obtained.
PURe® offers incredible performance, but in simple terms – this technology creates a protective layer that prevents any potential conductive heat loss. It keeps the inside insulated and warm – even during the colder months. These doors will enhance energy-efficient standards you may have created whilst maintaining the sleek aesthetic.
Narrow Sightlines
Narrow sightlines are present on both bi-fold suites – this complements other window ranges, offering a sleek and polished aesthetic. In simple terms, to explain to your clients, narrow sightlines offer larger glass units – reducing vertical dividing sections and creating an uninterrupted view of the outdoors. More light indoors and a neater outdoor finish.
High-Performance Gaskets
Another performance indicator of PURe® Bi-fold doors that can obtain and improve heat insulation capabilities is high-performance gaskets as standard. The gaskets create a seal along the door frame and reduce the infiltration of sound, light, drafts, moisture, fire and smoke. This is essential when the bi-fold door panels are folded against each other and for increased safety and energy-efficient standards.
Although the gaskets are visible along the door perimeters, they are slightly unnoticeable to ensure a stylish and sleek aesthetic is always maintained.
Low-U Values
Both aluminium bi-fold ranges surpass energy levels and expectations and offer incredible U-Values as low as 1.19 W/m2K when calculated as a CEN Standard door.
However, quality installation is important, and without it, you may compromise on the final U-Value achieved. On the other hand, if fitted correctly, these doors will meet energy-efficient standards.
Robust Aluminium
Aluminium, out of all materials, has the highest performance value. It’s low maintenance, durable, scratch-resistant, flexible, and weather resistant. Both bi-fold door ranges offer unparalleled aluminium benefits.
