Security Doors

Engineered Protection with Architectural Elegance

Minimal Frame Projects offers a premium range of security doors that combine high-performance protection with sleek, modern design. Whether safeguarding residential properties, commercial buildings, or high-security facilities, our solutions deliver certified resistance against forced entry, ballistic threats, explosions, fire, and smoke — without compromising on aesthetics.

From aluminium doors with slim sightlines and bullet resistance, to robust steel systems tested to RC6 and FB7-NS, each door is engineered for specific threats and seamlessly integrates with surrounding architecture. Options include panic hardware, electronic access control, fire ratings, and anti-suicide features for custodial environments.

All systems are fully tested to European standards (DIN EN), and can be tailored with bespoke finishes, automation, and multi-threat configurations — ensuring your entrance is not only secure, but refined.

Aluminium doors series S2es-d

High-security aluminium doors with advanced protection against forced entry (up to RC5), ballistic threats (up to FB7-NS), and blasts (up to 500 kg of explosives), without compromising on design flexibility or ease of use.

Sliding Door & windows install

We had two Velfac windows, a large picture window, two skylights and a set of 3 sliding minimal frame doors installed. Very happy with the products but the doors are still not fully operating - 2 years on. Pro's: - Nathan, our sales contact was very well informed and provided good advice at the early stages. - Contracts and payment points were all clear - Technical drawings clear - Products are good quality and feel - Bob was quick to attend when we had a big issue after install - Good value Con's: - Builders left to interpret the window requirements - a video walkthrough together would have instilled more confidence to both parties. Even though all worked out fine. - Sliding door product is not operating due to damage arising from previous fixes. Still waiting a fix; communictions ongoing.

Super smooth experience

Super smooth experience! Everyone MFP were easy and honest to work with. The fitting team lead by Jason did an exceptional job craning our glass roof up and over the house! The glass itself is beautiful and was measured to perfection. Top work thank you all!
