No drilling into the frame
The system uses brackets fitted around the glazing bead on compatible windows, avoiding screw holes in the uPVC.

Neat, no-drill frame fitting
Perfect Fit blinds clip into compatible uPVC window and door frames, moving with the glass and leaving sills and handles easier to use.
The system uses brackets fitted around the glazing bead on compatible windows, avoiding screw holes in the uPVC.
The blind stays attached when a door or tilt-and-turn window moves, rather than swinging away from the glass.
The framed blind sits close to the pane and leaves the surrounding recess clearer than many traditional fittings.
Useful before you buy
Perfect Fit is not simply a normal blind pushed against the glass. The blind sits within its own slim frame, which clips onto brackets positioned between the rubber seal and glazing bead. That is what creates the close, integrated appearance.
It is particularly useful on glazed doors, French doors and tilt-and-turn windows. Because the blind travels with the opening, it avoids the movement and clatter that can happen with a blind mounted above the door.
Not every uPVC window accepts Perfect Fit hardware. Bead depth, shape, seal condition, handles and vents all need checking. We measure the glass and frame rather than guessing from the overall window size.
The honest answer may be that another system fits better. A no-drill claim is worthless if the frame fouls a handle, blocks a vent or never sits square.
Different Perfect Fit systems can carry roller, pleated or Venetian blinds. Pleated fabrics are popular for conservatories and glazed doors; Venetian slats provide adjustable privacy; roller fabrics keep the appearance simple. The window and the result you want decide the best combination.
Where it works
Straight answers
The details that matter before you choose, measure or arrange a visit.
On compatible frames, the brackets fit around the glazing bead without screws into the uPVC. The window must be checked for suitability first.
No. They are mainly intended for suitable internally beaded uPVC windows and doors. Frame details, seals, handles and vents can rule the system in or out.
Correctly selected and fitted brackets are designed for the system. We check the bead and seal condition before recommending it.
Yes, blackout fabric options are available in some systems. As with any blind, exact edge performance depends on the frame and product construction.
