Secure your home from every angle with the Latham’s Steel Security Back Door, a premium 63mm steel door engineered to deliver maximum protection at the rear of your property, without compromising on style or thermal performance. Available in three distinct designs, flush, traditional 6 panel, and cottage style, there’s a back door to complement every home, from modern new builds to period properties and rural retreats. Back doors are one of the most common entry points for intruders, making the choice of door critical. Our Security Back Door combines outstanding aesthetics with the strength and security credentials you’d expect from a leading steel entrance door.
Three Styles to Suit Every Home
Choose from three carefully crafted designs to match your home’s character and architecture. The Flush design offers sleek, minimal lines and a contemporary finish ideal for modern homes and extensions. The Traditional 6 Panel brings timeless heritage appeal, perfectly suited to period properties and classic family homes seeking enduring kerb appeal at the rear. The Cottage Style captures the warmth and charm of rural architecture, with elegant panel detailing and glazing options that beautifully frame garden views and outdoor living spaces. All three designs are available in a range of 15 contemporary colours and satin finishes for a seamless, cohesive look.
Built to Withstand
Each door slab is crafted from galvanised Welsh steel, bonded to a reinforced perimeter sub-frame of LVL and UPVC. Specifically designed to handle the additional exposure typical of rear-facing doors — including prevailing winds, driving rain, and limited visibility from the street — this construction ensures outstanding durability, weather resistance, and long-lasting performance. Featuring innovative three-layer manufacturing technology, the door surface meets the highest European standards for corrosion and UV resistance (Ruv4 and RC5 as per EN 10169), guaranteeing low maintenance and enduring beauty for years to come.
A-Rated Energy Efficiency
Designed for superior thermal performance, all 63mm doors achieve U-values below 1 W/m²K with A-rated energy efficiency. This is achieved through a 63mm insulated slab, laminated triple-glazed units, and an innovative steel-reinforced UPVC frame — reducing heat loss through one of the home’s most vulnerable areas, enhancing comfort, and meeting future building regulations. Manufactured in the UK using sustainable materials and processes, the foam core is CFC and HCFC-free, ensuring responsible manufacture without compromise on performance.
Rear Door Security You Can Rely On
Back doors demand the highest level of security, and our door delivers. Each doorset holds Secured by Design (PAS 24:2016) accreditation and is fitted with a high-security multipoint locking system, rigorously tested against drilling, picking, and crowbar attacks, the most common methods used to force rear entry. Three-star cylinders provide advanced protection, Grade 12 adjustable hinges are supplied as standard, while triple hinge dog bolts (two sets supplied as standard) provide an additional layer of resistance against forced entry. All hardware is manufactured from 304 stainless steel for maximum corrosion resistance and long-term durability.
