SIERRA MIRA

A closer look.

The MIRA is built for those seeking top-tier security, energy efficiency, and noise reduction. Made from high-quality stainless steel, the door features an interior filled with PUR polyurethane foam and wood, with a 2.2-inch thick door slab for enhanced insulation and strength.

Key to its performance is the dual sealing system, where one seal is located in the frame’s dap, and the other is in the supporting part of the door slab. This feature reduces vibrations, prevents heat loss, and maintains the door's volume regardless of environmental changes. The door’s frame includes anti-burglar reinforcements at critical points, including the hinges and locking areas.

The ROTO locking system is engineered for security, featuring a strip lock with an independent upper lock and three reinforced anti-theft bolts. For extra peace of mind, the set includes three adjustable anti-burglary hinges. The door comes equipped with an aluminum threshold, three anti-theft bolts, and two sets of key inserts. For ease of use, a normal door handle is provided, with a T-bar long handle available as an additional option. For solid doors, a viewfinder is included for added convenience.

In terms of insulation, the door boasts an R-value of 4.8 for solid doors and 3.8 for glazed doors, making it an excellent choice for energy efficiency. It also provides 31 dB of acoustic insulation (without glazing), making it a perfect option for noise-sensitive environments. If opting for glazed doors, triple-glazing offers enhanced thermal and soundproof properties.

The MIRA comes prehung, meaning it's already mounted onto the frame for quick and easy installation. This saves time and effort, allowing you to enjoy your new door without the hassle of complicated assembly.
