With more people choosing to stay in their existing homes and upgrade them because of the slow housing market, the investment in an external folding door can make an instant and stunning visual impact on any home, says door manufacturer Premdor. <br><br>Creating a synergy between home and garden, Premdor’s external folding doors are easy to operate, stylish and extremely secure, meeting all legislative and industry requirements, claims the company. The doors are 54mm thick and are supplied ready to assemble with most components factory pre-machined to ensure ease of installation on site, Premdor says. <br><br>Both doors and frame are manufactured using a modern engineered construction for stability and have a hardwood core with 3mm oak or hardwood veneer on each visible surface. To assist with immediate installation the set is factory finished with three coats of hard wearing, high build, micro porous finish for long lasting protection, says Premdor. All Premdor folding door sets come complete with doors, frame, cill, hardware, threshold, locks, handles, weather and draught seals. <br><br><a href="http://www.premdor.co.uk">www.premdor.co.uk</a>
