Protect Upvc's bi-folding doors create seamless indoor-outdoor transitions with slim profiles and energy-efficient glazing.

The precision-engineered tracks accommodate double or triple glazing options, while powder-coated finishes ensure long-lasting durability. Available in both PVCU and aluminium materials to suit different architectural styles.

Brilliant. Highly recommend. Competitive prices and first class service. We had new composite front & back doors and then all new downstairs windows. Knowledgeable & reliable company.

Great company to deal with. Had a set of 5 door alumium bifold doors made and fitted from Pro-tect UPVC. Really happy with the quality and the fitting team was skilled and professional. I wouldn't hesitate to recommend this company to family and friends.

Fantastic company, good quality doors and windows, always helpful and responsive. We've used them several times to replace all the old wooden windows in the house over the last decade, or so. The new patio doors and windows in the extension are great.
