When it comes to front doors that combine substance, style and performance, the Grandeur collection from Distinction Doors represents a step above. Designed for homeowners and projects where impact matters, this premium range elevates expectations, marrying robust engineering with refined aesthetics for entrances that are truly unforgettable. 

What Is the Grandeur Range?

The Grandeur range is Distinction’s enhanced 70 mm thick composite door collection, a significant upgrade on standard 44 mm doors, offering deeper insulation and greater presence. 

This isn’t simply a thicker door. It’s the evolution of Distinction’s double rebated door heritage, reimagined with new designs, glass options and security refinements that reflect growing demand for premium alternatives to steel and aluminium entrances. 

Built Around a 70 mm Double Rebated Core

At the heart of the Grandeur collection is its 70 mm double rebated core, which delivers a range of performance advantages:

• Superior thermal performance: The core is approximately 50 % thicker than standard composite doors, resulting in significantly improved heat retention.
• Enhanced energy efficiency: The increased thickness,  combined with high‑quality materials, provides around 35 % better thermal efficiency compared with the standard 44 mm door, helping homeowners reduce heat loss and manage energy use more effectively.
• Effective weatherproofing: The double rebate design naturally accommodates robust sealing, helping shield interiors from draughts, rain and wind, ideal for UK climates.
• Improved sound insulation: The substantial core, paired with sealing technology, helps reduce outdoor noise ingress,  an asset in busier residential or urban areas.

These doors are compatible with Distinction’s range of decorative and triple‑glazed glass, further enhancing thermal and acoustic performance while delivering striking visual appeal. 

Elevated Security and Build Quality

Security is central to the Grandeur ethos. Manufactured with an impact‑resistant GRP skin, rigid polymer sub‑frame and quality multi‑point locking hardware, these doors go beyond basic protection. 

A newly introduced security board feature strengthens each slab further, reinforcing resistance to intrusion and offering peace of mind for homeowners, particularly on larger openings or premium properties.

Design That Matches Performance

While performance is essential, the Grandeur range doesn’t compromise on aesthetics. Door styles span traditional to modern, incorporating subtle woodgrain effects that enhance visual character while remaining durable and low‑maintenance. 

Homeowners can choose from an expanding palette of colours and decorative glass options, allowing for tailored solutions that complement architectural context and personal style. 

Installer and Trade Benefits

For installers, fabricators and specifiers, the Grandeur collection offers several practical advantages:

• Straightforward installation – fits existing PVC‑U outer frames and utilises Distinction’s deglazable cassette system for efficient fitting.
• Premium upsell opportunity — larger, thicker doors with high‑end finishes appeal to homeowners looking to upgrade, supporting higher project value.
• Broader specification range — styles drawn from signature, cottage and contemporary collections ensure versatility across different projects and architectural styles.

Designed to Impress, Engineered to Perform

The Distinction Doors Grandeur range exemplifies a premium front door solution, combining robust performance, elevated security and bespoke style options. Whether for luxury homes, refurbishment projects or high‑end developments, it gives trade partners a compelling product to specify with confidence.

Grandeur, because first impressions matter, and performance should never be compromised.
