Furring strips play an essential role in the installation of horizontal vinyl siding, particularly when it comes to ensuring that the siding is installed correctly and effectively. Installation of furring strips around doors and windows in a vertical orientation allows for improved alignment and support of the siding panels. This vertical installation helps to create a proper substrate for the siding, ensuring that it adheres correctly and has adequate space for expansion and contraction, which is vital given the materials' response to temperature changes.
Additionally, vertical furring strips can help facilitate proper drainage and air circulation, minimizing the risk of moisture build-up that can lead to mold and mildew beneath the siding. This strategic placement around openings like doors and windows also enhances the overall aesthetic quality by providing a better edge finish for siding installation.
Other installation methods, such as horizontal-only furring strips or angled installations, might not offer the same level of support and alignment needed around crucial areas like door and window frames. Not using any furring strips at all would typically be inappropriate, as it could compromise the integrity and durability of the siding installation.
