HNS‑W – The Most Advanced Bullet‑Resistant Window in the Nordic Region

HNS‑W (High‑grade Nordic Security Window) represents the pinnacle of Finnish security engineering. It is developed by Helsingin Network Service Oy and Woller Oy – two Finnish companies whose expertise and long‑standing experience are evident in every detail of the product.

Developed in Finland. Manufactured in Finland. Built from European NATO‑sourced materials.

HNS‑W is designed and manufactured entirely in Finland. All critical raw materials are sourced from European NATO countries, ensuring exceptional supply security and independence from U.S. tariffs and geopolitical influence. When security is critical, the supply chain must be reliable – and we have ensured exactly that.

Tested and certified exclusively by respected, accredited laboratories

Reliability is a non‑negotiable principle for us. For this reason, HNS‑W has been tested in both Finland and Germany by independent, accredited institutions:

EN 1627 RC4 – certified in Germany
EN 1063 BR6NS – certified under Deutsche Akkreditierungsstelle accreditation
EN 1522–1523 FB6 – tested in Finland
NATO STANAG 4569 Level 1 (AEP-55 Vol 1) – Kinetic Energy – tested in Finland by Eurofins Expert Services Oy

When we say certified protection, we mean it literally.

The Lightest and Thinnest Bullet‑Resistant Window in the World

The structure of HNS‑W is in a class of its own. It is the lightest and thinnest NATO STANAG 4569 Level 1 and

BR6/FB6‑rated bulletproof solution on the market.

Profiles

T‑profile: 9.2 kg/m → 36.8 kg/m²
L‑profile: 7.2 kg/m → 28.8 kg/m²
Total frame thickness: only 70 mm

Glass

Hammerglass BR6‑NS: 90 kg/m², thickness only 39 mm – competing BR6‑rated glasses are typically 63 mm thick and more than 60 kg heavier per square meter

Insulated glass option

For designers requiring improved U‑values, we offer a configuration consisting of:

BR6 ballistic glass + 6 mm tempered energy glass + 12 mm spacer

Total weight: 104.4 kg/m² → more than 50–60 kg lighter than competing solutions

HNS‑W – When Security, Quality, and Supply Reliability Are Critical

HNS‑W is more than a product. It is a solution that combines Finnish engineering excellence, European materials, and proven ballistic performance. It is designed for situations where no compromises can be made.
