Bifold Fitting - Outside In The folding sliding door market is forecast to increase to over £100m by 2014 as more customers realise the benefits of ‘bringing the outside in’ – enhancing their lifestyle and adding value to their property in the process. Here Chris Coxon, Marketing Manager at Eurocell, shows how installing this type of door is easier than you think.Step 1Before installing the folding sliding door, check that the structural opening is cleared of dust and debris. Make sure that the DPC is in position and undamaged. Aspect folding sliding door is suitable for a maximum opening of 6m wide x 2.3m high. Step 2Measure and cut the base cill to size, glue the cill end caps on to the cill. Offer the base cill into the opening to check that it is level across its overall length before fixing to the aperture with a generous bead of silicone.Step 3Fix the traffic door handle and lock cylinder and then carefully lift the door into position making sure it is plum and square without twist.
Step 4Fix the door into the opening using appropriate fixings. When fixing down the cill, ensure that screws are sealed to prevent water ingress. The slim-stepped outer frame on Aspect contains all the door hardware, which makes installation much easier because there’s no need to cut plaster or make alterations to the property to make sure the door fits.Step 5Once the door is fixed in position, check that the sashes operate correctly before beginning the glazing. The doors are available double glazed with a U-value performance of up to 1.3Wm²/K, or triple glazed with a U-value of 0.9Wm²/K. Each door has a built-in four-rail aluminium roller track so that it glides open or closed smoothly and effortlessly. Step 6Hinges can easily be adjusted by loosening off the two screws on each leaf and then sliding the adjuster peg to achieve lateral adjustment. Once this is done, tighten the screw to lock in position. The traffic door has adjustable keeps. Roller adjustment is achieved by loosening the two grub screws and then using a 5mm Allen key to make up to 10mm of vertical adjustment.
Step 7The unique D-shaped handle allows the doors to fold back flatter, whilst including an intelligent anti-mishandling feature that stops the shoot bolt scraping across the floor. This also protects the bolts from being damaged and needing replacement – the main cause of repairs on folding sliding doors. Fit the trim, which hides the seals between the door leaves and means customers won’t see a black line when they’re closed.The first impression of Aspect is its ultra slim frame, which means a larger glazed area. That gives installers a valuable selling proposition – because flooding the property with natural light and an enhanced feeling of space creates a real ‘wow’ factor – giving you a much better chance of converting the sale.With a 215% increase in the market size for folding sliding doors within the new build sector forecast by 2014 (24,200 installations, Palmer Market Research) and continued interest from homeowners, there’s never been a better time to take a look at this lucrative sector.

Get the speed and power only a hydraulic operator can offer. A two horsepower electric motor runs a hydraulic pump and supplies pressure to a hydraulic wheel motor. System comes complete with a safety brake to lock door in position in the event of hydraulic pressure loss. System is shipped fully assembled, wired, plumbed and tested. Maintenance free operation in all climates. Strong, welded-steel frame assures long life Hi-Fold Door panels are built with double, rectangular, structural-steel tubes at the center hinge line (2" x 4" on doors to 46’ wide; 2" x 6" on wider doors) and 1 1/2" or 2" square structural-steel tubing, depending on door size, for the remainder of the frame. Doors over 46’ wide are made in two sections that bolt together through super-strong, 1/2" steel butt-plate joints. Strong mounting hinges (4,5,7 or 9, depending on door width) are welded to the top rail. Powerful drive system assures dependable operation Name brand electric motor (1 hp to 2 hp depending on door size) with worm-gear speed reducer connected to a torque-free, 2" diameter drive shaft by a double jack-shaft and heavy-duty roller chain opens the Hi-Fold Door.
Motor and electrical systems are mounted 18" or more above the floor on the side of the door for easy maintenance and to meet the National Electrical Code, Section 513 specifications, pertaining to aircraft hangars. Pulley-free design minimizes cable wear and promotes safe operation Hi-Fold Doors are delivered completely rigged. 7/32" lift cables with a 5 to 1 safety factor are secured to top rail of the door and wrap around large diameter drums on the full-width drive shaft as the door rises. Cable guards cover the lift drums to protect people, clothing, and pets. Lift cable "poppers" (inset photo) automatically push the center hinge away from the building as the door rises. Automatic jamb latches optional (U.S. Patent No. 5,343,923) Patented automatic, "knee-action" jamb latches release the Hi-Fold Door when opening, and grab latching hardware on your building when closing, to pull it tight against the jambs. An optional full-width safety edge reverses the door if an obstacle is encountered.
Automatic cane-bolt, on doors over 40' wide, secures and releases the door at the floor. Optional radio control lets you operate the door from outside your building. Optional remote antenna increases transmitter range. Free Standing Door Frame Jambs and header support for door operation. This frame is ideal when building structure is inadequate or questionable. Jambs can be anchor bolted to concrete or set below grade on a footing. Header to be attached to building to assist with horizontal loads. Welded-steel trusses withstand strongest wind loads All Hi-Fold Doors receive one to three inside trusses. Made of heavy-gauge, steel tubing with angle-iron webbing, they provide extra strength to control wind-load deflection when the door is closed and to help the "dogleg" center hinge eliminate sag when the door is open. Doors over 26' wide receive full-width trussing in the middle of the top and bottom panels, plus the bottom truss, which holds the drive system. Smaller doors require the bottom truss only.
Convenient "open-close-stop" push-button control 24-volt system mounts at any handy location inside the building near the Hi-Fold Door. Normally does not require conduit (depending on local codes), which allows pre-wiring and flexible cable on the building frame. For safety, the operator must push the "stop" button before changing door direction. Can be stopped and started at any midpoint. Electric brake is standard. Comes factory-wired for 110-volts on 1 hp doors; 220-volts on 1.5 hp& 2 hp doors. Radio remote control is optional. Auxiliary arms provide high clearance advantages (U.S. Patent No. 4,609,027) Patented auxiliary arms on each side of the Hi-Fold Door enable it to open completely while requiring less overhead space. As the door rises, smooth rolling steel wheels on the arms contact the optional reinforcement rails on both jamb posts to provide strong, dependable support. Double-strength center hinge, welded-steel wind trusses and strong, vertical joints combine with the auxiliary arms to hold the door in the horizontal, sag-free, full position.
Walk doors and windows are optional Add to the convenience and appearance of your Hi-Fold Door by ordering walk doors for easy access to your building and/or windows for natural lighting inside. Choose from a wide variety of attractive styles and sizes. Framed openings for the door and windows you desire are welded into your Hi-Fold Door panels at the factory. Walk door and windows are then easily mounted in place after the Hi-Fold Door is installed on your building. Double-strength center hinge design eliminates sagging Unique, "dogleg" center hinge design, formed by the rectangular-steel members on both the top and bottom Hi-Fold Door panels, provides a "double-strength" beam that virtually eliminates sagging in the full-open position. This strength, combined with the strength of the welded-steel trusses on the inside of the door, provides even greater resistance to wind-load when the door is closed. A floor cane-bolt on all doors over 40' wide further resists wind-loads.
Single location crank latch (patent pending) Mounted inside building on door, these self-adjusting latches tightly draw and secure Hi-Fold Door against jambs to protect against thieves and bad weather. Electrical interrupt supplied to guard against damage if locks are not fully released prior to operation. A durable bottom weather seal adjusts to floor irregularities; 9" and 12" top door seals are optional.& 2 hp doors. Shipped fully assembled for fast, easy installation Hi-Fold Doors are custom built for every job and shipped to your building site completely assembled and wired. When you're ready to install, simply hoist the door into place over the opening, fasten the hinges to the building header, adjust the high clearance auxiliary arms and connect the wiring to your power source. Except for applying the skin, your Hi-Fold Door is ready to operate. Retrofit installations retain full door opening clearance Hi-Fold Doors are ideal for replacing worn-out or hard-rolling sliding doors, troublesome overhead doors and closing doorless opening on existing buildings without changing building design.
