What is a Perfect Fit® Blind?

A Perfect Fit® Blind is a revolutionary window treatment system that fits neatly into a surrounding aluminium frame. The frame clips directly between the glass pane and the rubber glazing bead of double-glazed uPVC windows or door panels.
Key Engineering Characteristics of Perfect Fit®:
  • Zero Drilling or Screws: Stainless steel bracket sliders fit under the rubber seal without puncturing the uPVC frame.
  • Frame Colour Matching: Custom powder-coated frames available in White, Anthracite Grey, Black, Golden Oak, and Mahogany to match your window profile seamlessly.
  • Integrated Window Movement: Blind becomes part of the window, so windows and doors open, tilt, or slide freely.

What is a Traditional Roller Blind?

Traditional roller blinds consist of a single sheet of stiffened decorative fabric wrapped around a top aluminium barrel, operated by a sidewinder plastic or metal bead chain. They are mounted using top, side, or face-fix brackets screwed into the masonry lintel, timber trim, or plasterboard recess.
While roller blinds remain highly popular for standard square windows due to their low price point and vast fabric selection, they carry inherent drawbacks on doors and tilt & turn windows. The mounting brackets force the fabric away from the glass, creating 15mm-20mm side light leaks and causing the blind to swing loosely when windows are opened for ventilation.

Architectural Comparison

Perimeter Light Leakage & Blackout Performance
Standard roller blinds leave gap spaces on either side where the operating mechanism resides. Sunlight streams through these gaps into bedrooms and nurseries. Perfect Fit frames enclose all 4 sides of the fabric, blocking perimeter light leakage and offering superior room darkening.
Child Safety Standards & Window Sill Clearance
Perfect Fit blinds operate using an integrated bottom handle tab with no operating chains or cords, making them inherently child and pet safe by design. Furthermore, because the blind sits inside the glass bead, 100% of your window sill remains clear for plants, taps, or decorations.
Window Warranty Preservation & No-Drill Security
Drilling screw holes into uPVC window frames or bi-fold door trims frequently voids the manufacturer's multi-year frame warranty and can compromise double-glazing seal integrity. Perfect Fit blinds require zero drills or screws, designed to protect your window frame warranties.
Tilt & Turn Windows and Door Clearance
Tilt & turn windows open inwards into the room. A traditional roller blind mounted inside the recess must be rolled up completely before tilting or opening the window. Perfect Fit blinds hug the glass pane flush, allowing windows and French doors to open smoothly without catching or swinging.
