Why choose Alumina French doors over bi-folding doors?
The main difference between French doors and bi-fold doors is that with French doors, both doors open from the centre, with one pane at each side of the aperture - whilst 2-pane bi-fold doors both fold back to one side. So, if you're looking for symmetrical, cost-effective doors that don't require a track and roller system, French doors may be the best choice for you, but if you'd prefer to stack the panes to one side or add a little 'wow' factor then you should consider bi-folding doors.
Are aluminium flush French doors energy efficient?
Alumina French doors are designed to offer exceptional thermal efficiency with remarkable U-values as low as 1.2 W/m²K. This is made possible due to the incorporation of the patented polyamide lock, which is based on Liniar's ModLok™ technology. Thanks to this innovative feature, these 70mm flush aluminium French doors can effectively retain heat and maintain a comfortable indoor temperature while reducing energy costs.
What threshold options are available for aluminium French doors?
Alumina doors offer customers the convenience of choosing from a variety of five threshold options. These options range from the rebated aluminium frame to the 23.5mm high low threshold and the Part M compliant threshold with tray. This ensures that customers can select the most suitable threshold option for their family's specific needs and requirements.
Are aluminium French doors weather resistant?
A full size Alumina door has been subjected to thorough weather testing, which included a thermally broken threshold. The outcome was truly remarkable, surpassing the minimum standards for both air and water tightness by more than twice the maximum pressures specified in BS 6375.
What glazing options are available for aluminium French doors?
When selecting glazing for your Alumina French doors, you'll have the option of choosing between 28 mm double glazing, 36 mm triple glazing, or 40 mm triple glazing. Each of these options offers a different level of thermal efficiency and its own unique benefits and considerations, so it is important to carefully consider your specific needs and preferences before making a final decision. Whether you prioritise energy efficiency, noise reduction, or aesthetic appeal, there is a glazing option that will meet your requirements.
