Beautiful aesthetics combined with an incredibly tough construction make GRiPCORE doors the ultimate destination for style and security. Its high strength and rigidity ensure this composite door always performs.

Composite Front Door Designs

Bespoke Style

GRiPCORE composite doors are perfect for customisation. The Glass Reinforced Plastic skin (GRP) can be painted in any colour to suit your taste. We offer an attractive range of stock colours, including anthracite, white, black and tan. Our doors are ideal for the discerning homeowner.

Unparalleled Performance

GRiPCORE technology offers superior benefits to anything else on the market. Coupled with our advanced uPVC construction and secure locking systems, this composite door provides exceptional protection. With a 10-year warranty, you’re only getting the best.

Ultra-Low Maintenance

Hybrid technology featuring a cross-laminated timber core and GRP skin guarantee GRiPCORE doors stay intact. They won’t crack, move or de-laminate. No re-painting is required; our doors are designed to save you time and money.

Excellent Energy Efficiency

Our doors offer unrivalled thermal efficiency. Like our foam filled composite doors, GRiPCORE technology can achieve an ultra-low U Value of 1.0 W/m²K or better. The hybrid build is 15-20% more energy efficient than standard doors. Built to the highest standard, GRiPCORE doors keep homes warmer.

Advanced Security

Sternfenster only fits the most secure front doors. GRiPCORE doors are no exception – they feature multi-point locking mechanisms and high-grade security hardware. Our doors are crafted to keep you and your loved ones safe. Security is imprinted in the DNA of GRiPCORE technology.

GRiPCORE Doors

Outstanding Durability

Engineered to perfection, the solid inner core comprises three layers of cross-laminated hardwood. It’s encased with Laminated Veneer Lumber and features hardwood stiles and rails designed to stop water ingress. GRiPCORE is the ideal composite door for homeowners who require long-term performance.

Inspired Options

We put you in creative control of how your door looks and operates. Sternfenster offers a beautiful range of colours, styles, glass designs and hardware accessories. You’ll get a stylish door that’s unique to you.

Guaranteed Reliability

GRiPCORE doors are stronger and more thermally stable than any other door. The hybrid construction ensures a 3mm maximum thermal movement – it performs in the blazing heat and pouring rain.

GRiPCORE Doors

Weatherproof & Secure

DOORCO’s renowned 4mm GRP skins encase the door, ensuring it’s completely protected from the elements. GRiPCORE doors are engineered to protect you and your home.

GRiPCORE Doors

Hybrid Core

A fusion of modern and traditional materials engineered to the highest calibre, the advanced core makes this door a market leader. It’s the first composite door to feature GRiPCORE technology – nothing else comes close.

Blue Composite Doors

Exceptional Operation

GRiPCORE doors with a slam shut lock are ideal for south-facing entrances. The hybrid slab performs better than the standard composite slab. It’s less likely to experience thermal movement in hot weather, ensuring the door operates smoothly every time. It works like new for years to come.
