Perfect Fit Blinds

Louvolite Perfect Fit® is a revolutionary system that enables window blinds to be fitted perfectly onto most double glazed windows and doors, with no holes drilled into your upvc frame! The unique Perfect Fit™ blind fits neatly onto the window and enhances your privacy because there are no gaps down the side of the blind. This design concept has nothing to do with Cosiflor, it was completely conceived by Louvolite, but what we do is take our superior designed, manufactured and better looking blinds and fit them within the Perfect Fit frames.

Louvolite Perfect Fit® is one of the most attractive and innovative window blind developments available on the market today. The system is unique because the window blind fits neatly into a stylish frame, available in white, brown, silver and golden oak, which moves together with the windows and doors when they are opened and closed giving you the perfect combination of shade and ventillation. The frames can even be easily removed for cleaning of the glass and the blinds.

Outstanding Thermal Efficiency - One of the unique features of the Perfect Fit frame is its thermal efficiency. The frame fits flush against your window to help reduce heat build up in summer and retain heat in winter, in turn keeping your cooling and heating bills to a minimum! To further maximise the superb insulating qualities add one of our energy efficient fabrics and save yourself up to 15% on your fuel bills by reducing the heat loss through winter.

  • Your blinds for conservatories are excellent expecially the Cosiflor blinds which are much easier to use and fit more neatly than the previous ones fitted by another company.
