- Self-adhesive thresholds (no drilling) and wide door thresholds
Door threshold guide: types, sizes, fitting & FAQ
Types of door threshold
- Flat threshold strips: for two hard floors at the same level, for example laminate to laminate. They cover the expansion gap and protect the floor edges.
- Ramp thresholds: for floors at different heights. The sloped profile bridges the step from the higher floor to the lower one.
- Carpet to laminate and carpet to tile door bars: hold the carpet edge on one side and finish the hard floor on the other.
- Carpet to carpet thresholds and cover strips: join two carpets neatly where they meet under a door.
- Wide door thresholds: for wider gaps and openings.
Aluminium, wood effect or UPVC?
- Anodised aluminium: rigid and hard-wearing, in silver, gold, champagne, black, inox, brown and olive.
- Wood-effect aluminium: aluminium strength with an oak, beech, walnut, mahogany or wenge finish to blend with wooden and laminate floors.
- UPVC: lightweight, self-adhesive and budget-friendly.
What size door threshold do I need?
- Length: measure the width of the doorway between the door frames. Choose the next length up and cut to size: most profiles come in 90 cm, 1.8 m and 2.7 m, some in 1, 2 and 3 m. A standard internal door suits the 90 cm length; double doors and wide openings need a longer bar.
- Width: the profile width (for example 30, 35, 40 or 50 mm) must cover the gap between the two floors, plus a few millimetres on each side.
- Height difference: if one floor is higher, choose a ramp threshold rather than a flat strip.
How to fit a door threshold
- Measure between the door frames and cut the threshold to length with a fine-tooth hacksaw.
- Clean the floor so it is dry and free of dust and grease.
- Self-adhesive: peel off the backing, position the strip over the joint and press firmly along its full length.
- Screw-fix: mark through the pre-drilled holes, drill, plug if needed and screw down. Check whether screws are included on the product page.
Door threshold FAQ
What is a door threshold strip?
A strip, also called a door bar or floor trim, that covers the joint where two floors meet in a doorway. It hides the expansion gap, protects floor edges from wear and makes the change between floors safer underfoot.
Do I need a door threshold between two laminate floors?
Usually yes. Laminate needs an expansion gap at doorways, and a flat threshold strip covers it while letting the floor move.
Which threshold for carpet to laminate?
Use a carpet to laminate door bar. It grips the carpet edge and sits over the laminate, giving a neat, secure finish.
Can I fit a door threshold without screws?
Yes. Self-adhesive thresholds stick straight down. For busy doorways, a screw-fix threshold gives the most secure fixing.
How do I cut an aluminium threshold?
Mark the length, clamp the profile and cut with a fine-tooth hacksaw, then smooth the cut end with a file.
