JnL’S double-glazed doors are secure, durable and energy efficient. You’ll find the perfect new door available as French, bi-fold, patio, front and back doors. Choose from composite doors, wooden doors, uPVC doors and aluminium doors.

- 01

Our Range of Composite Doors

Your new composite front door lives and breathes the kind of individuality that makes the neighbours jealous. Get the classic look of real wood, minus the worry of the upkeep. JnL’s Double Glazing composite exterior doors look like a traditional, high-end hardwood door but with contemporary touches and a durable interior core.

uPVC Doors

Manufactured by us in our UK factory, our uPVC front doors and uPVC back doors are a practical choice for busy households that balance price with style. Built from high-impact uPVC constructed to UK building regulations, JnL’s Double  uPVC doors keep the cold out and stop heat escaping.

Aluminium Doors

We make our aluminium external doors with the highest-quality extruded aluminium alloy, then powder-coat them for an attractive, durable and low maintenance finish. With a wide choice of designs, colours and glazing options, you can tailor the appearance of your replacement aluminium door with the confidence that it’s secured by a Yale kitemarked 3-star cylinder lock for maximum security.

Sectional Garage Doors

Add a touch of class to your home with a steel sectional garage door. Made up of hinged sections that curve round and back along a track inside the garage, our steel garage doors save on space. The double-skinned panels are filled with 42mm insulating foam and all four sides of the door have rubber weather seals. 

Roller Garage Doors

Save valuable space inside your garage with an aluminium roller garage door. Rolling into a compact box behind the brickwork, roller shutter garage doors are ideal for taller cars and to maximise garage storage space.


An JnL Double Glazing porch does more than add extra space to your home – with tailored roof, brick, window and door options, it’ll give your property the “wow” factor. Plus, it’ll also increase your home’s energy efficiency and add an extra layer of security, with a top-of-the-range Yale kitemarked 3 star cylinder lock fitted as standard on the door.
