The Vista Bi-Folding door is the perfect addition to any home offering slim frame profiles and superior running mechanisms as well as enhanced thermal performance. All bi-folding doors have the option of either low thresholds for unimpeded, easy access, or rebated thresholds that offer improved weather resistance and there is a choice of opening configuration to suite your individual needs. Aluminium is much stronger than uPVC and doesn't require reinforcements which means it can also be used for larger openings without the need for bulky profiles and couplers. Most UPVC bi-folds can only extend to 750mm wide leafs or sashes but Vista aluminium Bi-folds provide 1200mm sashes. Vista doors are virtually maintenance free requiring only occasional cleaning and lubrication of locks and hinges. They also stay looking great for longer as the modern powder-coating delivers a hard-wearing finish which will last for years. All our aluminium frames feature a polyamide thermal break which enhances the thermal performance of the profile and improves the overall U Value. The doors feature high quality EPDM gaskets and weather brushes to aid weather resistance and security is assured by multi-point lock mechanisms which comply with the requirements of Building Regulations Document L 2010.

These fully finished external Bifold Doors feature a preservative-treated Engineered timber core, which is also treated with a water-repellent system for long-term stability and durability. The doors come factory-glazed with high performance LowE DG Units and the whole doorset is factory-finished in Anthracite Grey.
