How strong is the triple-paned glass we use in every Carbon home? We put it to the test.

If you’ve ever wondered exactly how much our triple-paned, imported windows can really withstand, then this one’s for you! Founder and CEO Sam Fertik had maybe a little too much fun putting a Carbon window through its paces - and the results prove it’s exceptionally tough and impressively secure.

Triple the Protection, Built-In

Every Carbon Home features triple-paned glazing for unmatched durability. On the exterior-facing side, laminated glass bonds two panes together with a polymer interlayer - so even if it cracks, the glass holds firm. On the interior, two tempered panes provide outstanding strength, rigidity, and thermal performance. The result? Glazing for windows and doors that’s as safe as it is efficient.

Tough Love: The Ultimate Stress Test

To prove it, in this video you’ll see Sam launching rocks - increasing in size, weight, and sharpness - at both sides of a spare pane. The laminated side cracks but holds together without shattering - in fact, it’s still smooth enough for Sam to run his fingers over, making it incredibly safe for family life. No-one is going to injure themselves on this glass even if an impact occurs. While over on the tempered side, the glass doesn’t even flinch; despite Sam’s best efforts, absolutely nothing is getting through these layers! This isn’t just high performance on paper - it’s resilience you can see.

Beauty Meets Unbreakable Security

The laminated, tempered, multi-pane glazing we import from Europe and use on every Carbon Home doesn’t just look stunning - it’s built to resist. Intruders won’t find a weak point, and as a Carbon homeowner, you’ll enjoy total peace of mind, knowing your glazing meet the highest standards for strength and safety.

Peace of Mind, Engineered from Day One

We don’t believe in compromises when it comes to your home. That’s why every design decision - right down to the composition of your windows - is made with the longevity of your home and your ‘lived experience’ in mind. As Sam says: “That’s the Carbon Way.”
