BEFORE YOU BUY ANOTHER BLACKOUT BLIND

10 REASONS TO LOOK BEYOND BLACKOUT FABRIC.

If you've owned a “blackout” blind and still seen daylight around it, you already know the problem. Here are ten reasons BLOCKER is designed differently.

AT A GLANCE

THREE WAYS TO DARKEN A ROOM.

Each approach solves a slightly different problem. This is where the differences usually show up once the room is actually dark.

How BLOCKER, a standard roller blind and blackout curtains compare
Consideration	BLOCKER	Standard roller	Blackout curtains
Perimeter light control	Designed around the whole opening	Edge clearance remains	Light can spill around headings and sides
Made to measure	Built from your submitted dimensions	Varies by product	Usually sized to cover an area
Measuring support	Six-point guide plus compatibility checks	Often width and drop only	Pole or track and drop measurements
Window check	Recess depth, handles and opening considered	Product dependent	Different fitting considerations

Comparison describes how each approach is typically designed. Individual products vary — always check the specification of the blind or curtain you are considering.

BUILD YOUR BLOCKER

1. IT DEALS WITH THE PART MOST BLACKOUT BLINDS IGNORE.

Blackout fabric can stop light through the material while leaving bright lines around the perimeter. BLOCKER is designed to control both.

Two windows side by side: a conventional blackout roller glowing around its perimeter, and a fitted BLOCKER system with no visible edge light — The same window, treated two different ways.

2. IT IS MADE AROUND YOUR WINDOW.

Instead of choosing the nearest generic size, you provide the dimensions of the actual recess so the system can be produced for that opening.

3. THE MEASURING PROCESS CHECKS THE WINDOW IN SIX PLACES.

Three width readings and three height readings help reveal the narrowest and shortest points of a recess that may not be perfectly square.

4. IT MAKES YOU CHECK THE OBSTRUCTIONS BEFORE YOU BUY.

Handles, locks, vents, trim and inward-opening sashes can matter as much as width and height. BLOCKER's ordering journey is designed to make those checks visible.

5. THE FRAME IS PART OF THE BLACKOUT STRATEGY.

The perimeter is functional, not decorative. Its job is to control the space around the blind where light commonly escapes.

6. IT IS DESIGNED WITH UK AND EUROPEAN WINDOW STYLES IN MIND.

Tilt-and-turn, casement, sash, fixed and bay arrangements all create different clearance questions. BLOCKER asks you to check the actual opening rather than assuming one answer fits every home.

7. THE FITTING GUIDE EXPLAINS THE WHOLE SYSTEM.

Assembly, perimeter preparation, positioning and final daylight checks are treated as part of the product — not an afterthought.

8. YOU CAN ASK FOR A COMPATIBILITY CHECK BEFORE MANUFACTURE.

If your window is unusual, send photographs and measurements before placing the order. It is far easier to look at an awkward recess together than to work around it afterwards.

9. THE DESIGN IS MADE TO LOOK LIKE PART OF THE WINDOW.

BLOCKER uses a clean, restrained visual language intended to sit neatly in a modern recess rather than looking like a temporary stick-on blackout fix.
