Clients are increasingly looking for designs that offer genuine period characteristics.
The Sheerline Classic Heritage Door directly meets this need, with a design reminiscent of iconic 20th-century steel doors that is increasingly popular with style-conscious clients. This Art Deco charm, however, does not come at the expense of modern requirements.
The door is engineered to deliver the high levels of thermal performance demanded by current building regulations, offering the perfect blend of classic aesthetics and future-proof efficiency.
This unique combination is made possible through a series of advanced design and engineering features.

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.
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.

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.
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.
