Client: Jerome Renehan - Valtra Developments Ltd Carpentry Contractors
Problem: Inconsistent partition-to-floor connections causing performance issues
Solution: Cullen Head Restraint Screw
Impact: Improved installation consistency and reduced risk of defects
Facts & Figures
Partition-to-floor connections represent a key risk area, where poor detailing or installation can lead to ongoing performance issues.
The Challenge
Creaking floors remain a persistent issue, often driven by the partition-to-floor connection above.
Limited regulation and inconsistent on-site enforcement make this detail difficult to standardise, leaving installers to manage a critical yet challenging connection where floor deflection must be accommodated.
The Head Restraint Screw (HRS)
At Cullen the process began with a clear on-site pain point that was widely recognised across the industry.
The goal was to develop a solution that was simple, compliant, and delivered consistent results every time.
The solution was the Head Restraint Screw (HRS) System, a two-part guide-and-screw, specifically designed to remove guesswork and improve installation reliability.
The Outcomes
Consistent, efficient installation achieved through a guided, engineered system that ensures correct alignment, reduces on-site variability, and minimises rework.
Improved long-term performance and compliance, with fewer deflection-related issues and callbacks, increasing confidence in structural integrity.
