Security isn't an add-on; at Blairs, it’s built-in.
In modern construction, security should never be an afterthought. At Blairs Windows & Doors, we believe that true protection is forged on the factory floor. Whether we are fabricating at our Greenock headquarters or our specialised Aluminium Hub in Hillington, security is engineered into the very profile of every window and door we produce.
Breaking Down PAS 24
PAS 24 (Product Assessment Specification) is the industry standard for enhanced security performance. It isn’t just a simple lock check; it is a series of brutal, physical tests designed to simulate a real-world attempted break-in.
To achieve certification, our products must withstand:
- Mechanical Loading: Applying extreme pressure to corners and locking points to ensure the frame doesn’t give way.
- Manual Attack: Testing the resilience of the glazing and hardware against tools like crowbars, chisels, and screwdrivers.
- Impact Resistance: Using a pendulum strike to simulate body weight or shoulder-charging against the door leaf or window sash.
By meeting these standards, Blairs ensures that our products provide a formidable barrier for any development.
Engineered Protection: Eurogrooves and Multi-Point Hardware
We achieve this level of security by utilising high-performance components within our ranges:
- Full-Depth Central Eurogroove: Our Kommerling O70 Gold® PVCu system features a central eurogroove that allows for the deep nesting of hardware. This depth makes it significantly harder for an intruder to lever the locking mechanism out of the frame.
- Multi-Point Locking Hardware: We don’t rely on a single latch. Our doors and windows utilise multi-point systems that engage at several different intervals along the frame, distributing force and ensuring the sash is tightly sealed and locked.
- Steel Reinforcement: Where structural strength is paramount, we use internal steel reinforcement to ensure the frame remains rigid under attack.
Why Certified Security is Non-Negotiable
For modern commercial and residential developments, PAS 24 is no longer just a nice-to-have – it is a critical requirement for several reasons:
- Building Regulations & Compliance: Compliance with Approved Document Q (and equivalent Scottish Building Standards) often mandates that easily accessible windows and doors meet PAS 24 standards.
- Insurance Requirements: Many commercial insurers require certified security standards before providing cover for new developments or hospitality sites.
- Project Certainty: For architects and main contractors, specifying a PAS 24-certified product from the Saveheat Glazing Systems Group eliminates the risk of non-compliance during site inspections.
- Occupant Peace of Mind: Whether it’s a social housing resident or a high-end hotel guest, the safety of the occupant is the ultimate measure of a project’s success.
