Unrivalled Thermal Efficiency with Thermlock

In a market driven by energy efficiency, superior thermal performance is a critical differentiator. Sheerline’s innovative Thermlock multi-chamber technology offers a definitive competitive advantage, providing almost double the insulation of systems using traditional polyamide thermal breaks. Its insulating chambers act as a thermal break, working with high-performance glazing to achieve excellent performance.

For your clients, this means a home that stays snug and warm, with reduced energy costs. Thermlock is a powerful selling point that demonstrates clear, tangible value.

Heritage Aesthetics

Authentic design is paramount for period refurbishments and high-end, style-conscious projects. The Classic Heritage Door achieves this with meticulous attention to detail. Key aesthetic features, including the signature ‘stepped’ look, a period-inspired lockbox, and ultra-slim sightlines of just 60.5mm, combine to faithfully replicate the sought-after appearance of 20th-century steel doors.

This Art Deco styling is carefully engineered to provide the historical authenticity that clients love. This allows installers to confidently specify the door for high-value projects where aesthetic integrity is non-negotiable.

Enhanced Security

For any homeowner, security is a non-negotiable priority. The Classic Heritage Door addresses this with an optional Secured by Design (SBD) upgrade. This is an official, police-backed security initiative recognised across the UK.

To achieve this accreditation, the door has passed the SBD’s stringent test criteria, which are based on principles of reducing crime through robust design. Offering this upgrade provides installers with a powerful tool to build trust and offer clients complete peace of mind, differentiating their proposal with a credible, third-party endorsement.

Versatile Configurations and Styling

To meet diverse project requirements, product flexibility is essential. The Classic Heritage Door offers this versatility through multiple configurations, including single and French doors with options for either internal or external opening. A palette of 12 stocked colour combinations provides ample choice for bespoke styling.

Crucially, the door is designed to be 100% aesthetically matched with the Sheerline Classic window range. This allows you to propose a complete fenestration solution for an entire property, enabling installers to secure larger, more profitable whole-house projects with a single, trusted, and perfectly cohesive system.
