Door Threshold / September 17, 2018 / Martine Letourneau.
Keeping an entryway looking great during construction and remodeling is now easier and more cost effective than ever. Bifold doors now form part of almost all new build home extensions due to their ability to open up large unobstructed openings allowing the new living space to seamlessly merge with the garden. The enormous growth in demand for these folding sliding doors in the UK in recent years has led to a substantial increase in the number and type of different door systems now available to the consumer. They are now widely available in a choice of materials and finishes with the three most popular being thermally broken aluminium upvc and hardwood.
3. SECURITY Most folding doors will feature a high security locking system but many still use face fixed or flag hinges that can pose a possible security issue and allow the hinges to be removed from the outside when the door is closed. Some upvc bifold doors may also use an exposed gearing system that is accessible from the outside of the door when the door is closed which can also pose a possible security threat. You can eliminate these potential security problems by ensuring you choose a folding door that has fully concealed gearing and hinge fixings.
Several sill manufacturers provide plastic threshold protection that is specific to the model of sill they are selling. Unfortunately heavy duty plastic protectors are not available for every type of entry threshold so the protection is not easy to obtain. There is one surface protection company on the west coast that does inventory plastic threshold protection for two of the most common sill profiles. For protecting sliding door tracks there are two types of threshold protection. The first is a hinged plastic protection that flips over the tracks of sliding doors to keep them clean from debris.
Tightly wedged shims will allow you to operate the door carefully. Open and close to check the door touching the weather stripping evenly top to bottom for any possible jambs twist. Adjust as necessary even though jambs may not flush with plaster top to bottom. A good carpenter wont assume the original door was installed correctly right? Check the brickmold reveal you should have consistent and even measurements side to side and top to bottom. Its unusual to have brick out of plumb to any great extent. Adjust shims again as necessary. Index the jambs in the rough opening and the shims to jambs with pencil for reference when installing the system permanently. Remember you only have one chance to get this installation right so be patient - you will be rewarded with a satisfying outcome.
