Perfect Fit Venetian Blinds (25mm Slats) — Sleek, and Smart

Perfect Fit Venetian blinds are designed to click seamlessly into your window frames — no screws, no drills, no mess. Using a clever frame system, they slot directly onto uPVC window frames, making them ideal for modern homes, conservatories, or anywhere you want clean lines and total control over light and privacy.

25mm Aluminium Slats

The 25mm slat width strikes a balance between light control, privacy, and style. It’s slim enough for a sleek look but wide enough to block glare or open up the view when tilted. You get precise control with a simple tilt or lift.

Perfect Fit Wooden Blinds

Bring warmth and natural beauty to your windows with Perfect Fit Wooden Blinds from the Sunwood range. These blinds combine the classic look of real wood with the smart functionality of the Perfect Fit system — giving you a clean, made-to-measure finish with zero damage to your uPVC frames. Crafted with 25mm wooden slats, each blind is made to order, available up to 150cm wide and 220cm high, to suit a wide range of window and door sizes.

Measuring & Installation Made Simple

Our measuring and installation guides are straightforward and easy to follow. The brackets slide effortlessly behind the rubber seal, and the blind frame clips on securely with no drilling required.

Operation is just as simple — with adjustable aluminium slats for precise light control, and a discreet tab on the bottom rail to raise and lower the blind to your ideal position.

Benefits of Perfect Fit Venetian Blinds

Drill-Free Installation

These blinds simply snap into place using brackets that slide behind the rubber seal of the window. That means:

No holes in your frames or walls
No damage to your window units
Fast and easy fitting — even for DIY beginners

Streamlined, Built-In Look

Because they sit within their own custom-fit frame, they become part of the window — neat, tidy, and secure. Perfect for tilt-and-turn windows and doors where regular blinds just don’t work.

Total Light & Privacy Control

Tilt the 25mm slats to:

Block direct sunlight while keeping your view
Create privacy without shutting out the room
Let in natural light without the glare

Ideal for Doors and Conservatories

Perfect Fit blinds move with the window or door. So when you open a door or tilt a window, the blind stays put — no swinging, clattering, or tangling.

Energy Efficiency

Because the blind sits so close to the glass, it creates an insulating layer. That means:

Less heat escapes in winter
Less sun-heat builds up in summer
Lower energy bills year-round

Low Maintenance

Aluminium slats are easy to clean — just wipe down. No fabric to fade or stain. Built to last.

The Bottom Line

Perfect Fit Venetian blinds with 25mm slats offer a clean, modern solution that fits right into your window frame — no hassle, no clutter. They’re practical, stylish, and built for the way we live now.
