C.U.in™ is our answer to the performance question that’s been dodged for too long. Using a suspended film inside the unit, it effectively creates triple-glazing levels of insulation — without the extra glass.

### Why This is the Year to Bin the Old Glass Habits and Get Smart With Your Glazing


Let’s start with a quick question: *When was the last time you looked at your glazing spec and thought, “Yes — this is genuinely doing something for performance, comfort and carbon?”*

If the answer is *“well... it meets regs”* — then we need to talk.

### The Gap Between ‘Compliant’ and ‘Comfortable’


Let’s be honest. The glazing industry is full of buzzwords: “high performance,” “eco-friendly,” “triple this, laminated that.”
 But when push comes to shove, **most units still force you to choose between weight, performance, and frame compatibility**.

What does that mean in real terms?

 	- Developers settle for ‘just enough’ to scrape through EPCs



 	- Architects compromise design intent for deeper profiles or bulkier frames



 	- Homeowners install triple glazing, then crank the heating anyway





Meanwhile, the cost and carbon burden ticks up.

### Enter C.U.in™ — A Smarter Glazing Solution for 2026 Projects


Here’s what we do differently at Crystal Units:
 We *engineered out the compromise*.

**C.U.in™** is our answer to the performance question that’s been dodged for too long. Using a suspended film inside the unit, it effectively creates **triple-glazing levels of insulation** — *without* the extra glass.

And the best part?
 It fits straight into your **existing double-glazing frames**.

So instead of redesigning façades, upgrading hinges, or speccing in bulkier profiles, you get the performance without the penalties.

### How It Performs — By the Numbers:



 	- **U-values down to 0.2 W/m²K****

**

 	- **Up to 45% reduction in heating demand** over traditional DGUs



 	- **Fully recyclable**, lower weight and up to 36% thinner than triple glazing



 	- **Proven energy savings** in Salford Energy House tests



 	- **Backed by independent lifecycle analysis** from Hilson Moran



 	- Used in real-world projects like *The Arc, The Forge, Watergate, and Elmsbrook House**

*




### Why You Should Care in 2026


Because this year is different.

There’s growing pressure from:

 	- **Stricter Part L & Part O standards****

**

 	- **Net zero targets for domestic and commercial buildings****

**

 	- **End users who expect sustainable choices by default****

**



And glazing plays a critical role — not just in tick-box compliance, but in actual **energy use**, **thermal comfort**, and **occupant wellbeing**.

If you’re in the business of designing spaces for the future, then what’s in your windows shouldn’t be an afterthought.

### Let’s Talk About Your Project


Whether you're:

 	- Planning a new residential build



 	- Retrofitting for EPC improvements



 	- Designing commercial spaces with a low-carbon spec



 	- Or just fed up with overengineered triple glazing
