The client – a regional housing developer – aimed to deliver safe, durable, and low-maintenance housing for young families and essential workers. The budget was tight, but local building regulations and tenant expectations demanded reliable security, fire protection, and thermal performance through harsh Balkan winters.
Before TOF DOOR was involved, the developer faced several obstacles:
Cost vs. quality gap – Low-cost door suppliers offered cheap products that failed fire tests or rusted within months. Premium European brands were reliable but 40–50% over budget.
Cold climate demands – Winter temperatures in the Balkans frequently drop below -10°C. Entry doors must prevent cold bridging, condensation, and heat loss (U-value < 1.8 W/m²K).
Fire safety compliance – Common area fire doors (stairwells, corridors) require FD30 certification to EN 1634-1, with full documentation for building approval.
Heavy usage & vandalism risk – Rental apartments see higher traffic and occasional abuse. Doors need impact-resistant surfaces, sturdy locks, and scratch-proof finishes.
Logistics & scheduling – Four buildings with different floor plans, plus a narrow construction window. The client needed just-in-time delivery to avoid on-site storage costs and delays.
TOF DOOR activated its trust-based, problem-solving approach – moving from “product supplier” to “safety partner”.
