Professional Grade Proline Threshold Door Sill For Inward Opening Doors

The Professional Grade Proline AM3EX Threshold Door Sill is a superior solution for enhancing the functionality and accessibility of inward-opening doors. Designed with precision and attention to detail, this threshold door sill offers a range of features that make it an ideal choice for both new installations and retrofits.
Ergonomic Design and Part M Compliance
One of the standout features of the Proline AM3EX is its ergonomic design, which has been rigorously tested to ensure compliance with Part M of the building regulations, specifically section 0.23. This compliance ensures that the threshold meets the necessary standards for accessibility, making it a suitable option for buildings that need to accommodate individuals with mobility impairments.
Versatile Installation Options
The Proline AM3EX threshold can be seamlessly integrated into various door frame configurations. It can be installed as the fourth side of the door frame, providing a continuous barrier against draughts and water ingress. Additionally, it can be retrofitted into existing setups, offering flexibility for upgrades without the need for extensive modifications.
Superior Sealing Capabilities
Designed to seal gaps ranging from 18mm to 23mm, the Proline AM3EX effectively prevents air leakage and enhances energy efficiency. This feature is crucial for maintaining a comfortable indoor environment and reducing energy costs by minimizing heat loss or gain through the doorway.
Innovative Drainage and Thermal Performance
Pre-drilled drainage holes in the threshold ensure that any water ingress is efficiently managed, preventing water accumulation and potential damage. Furthermore, the threshold is thermally broken, which means it incorporates a thermal barrier to prevent thermal bridging. This design feature helps meet stringent insulation requirements, making the threshold suitable for use with a variety of frame and door materials, including wood, PVCu, fibreglass, aluminium, steel, and carbon fibre.
Designed for Level Thresholds and Safety
The Proline AM3EX is designed to fit directly onto level thresholds, ensuring a smooth transition between indoor and outdoor spaces. This makes it particularly well-suited for homes with carpeted floors, where a level threshold can help prevent trip hazards. The non-slip surface of the threshold provides a safe grip even in wet conditions, enhancing safety for all users.
Aesthetic and Functional Finishing Touches
Supplied with end caps to close off the ends of the front channel, the Proline AM3EX threshold offers a neat and finished appearance. These end caps not only enhance the visual appeal but also contribute to the overall functionality by preventing debris from entering the drainage system.
Conclusion
The Professional Grade Proline AM3EX Threshold Door Sill is an exceptional product that combines ergonomic design, versatile installation options, and superior performance. Its compliance with accessibility standards, effective sealing capabilities, innovative drainage, and thermal performance make it an ideal choice for a wide range of applications. Whether you are installing a new door or upgrading an existing one, the Proline AM3EX offers a reliable and efficient solution to enhance both the functionality and aesthetics of your entryway.
