Weathered

The threshold of an outside door is a crucial feature of any door. It offers protection from the elements as well as an effortless transition from indoor space to outdoor. However, it is essential to strike the right balance between security and aesthetics when selecting the threshold for your external door system. In addition to being essential for weatherproofing the home thresholds also play a crucial role in user safety. They help prevent tripping and limit accessibility for people with mobility issues. There are a variety of thresholds, so customers can choose the one that is best for their home.
A weathered threshold is a great option for doors on the outside, since it offers exceptional rates of weather protection and also creates an effective barrier to keep water, wind and draughts out. This kind of threshold can be recessed/sunk into the floor leaving an upstand of 14mm, which reduces the risk of tripping and creating an effective seal against the elements. Weathered thresholds are recommended for all external doors because they provide higher levels of weatherproofing than unweathered options. The higher elevation of thresholds that are weathered can make them unsuitable for some users, particularly those using wheelchairs and pushchairs/prams.
Unweathered thresholds are generally smaller in height. Many are only a few millimetres from the ground. This means that they are less likely for them to cause accidents due to tripping. They can also provide an easy transition between indoors and outdoors which allows the two areas to be connected in a manner that is open and accessible. They may not offer the same levels of weatherproofing as a weathered option, but they are perfect for homeowners who want to enhance their home's appearance without sacrificing practicality or protection.
If you are planning to replace your french doors or they're currently fitted with a non-weathered threshold, installing a new threshold can be a simple DIY project. It will help reduce the unevenness of the gap at the bottom of the doors and guard against drafts and water ingress. It is possible to attach the new threshold onto an existing sill, however the threshold that was previously installed will need to be removed first. To take off the old sill, put an aluminum bar between it and the subsill. Carefully pull up the middle section. If the ends of your threshold are secured to the subsill and you want to remove them, use the hammer to break them away from the jambs. After removal of the threshold then sand it and clean off any mortar remnants. It is recommended that you apply a foam sealant that expands under the threshold prior to installing it again. This will keep it in place and fill any air gaps.
