Door Threshold Strips UK — Complete Range for Every Floor Type

Whether you are finishing a flooring project at home or working on a commercial installation, choosing the right door threshold strip is essential. At Stair Nosing Company, we stock a comprehensive range of door threshold strips — also known as door threshold bars, door bars, transition strips or floor transition strips — to suit every doorway, every floor type and every budget, with fast delivery across the UK.

Browse our full range below, from sleek aluminium door thresholds to realistic wood effect finishes, carpet door bars, LVT trims and wide threshold strips for larger gaps.

What Is a Door Threshold Strip?

A door threshold strip — also known as a door threshold bar, transition strip, floor transition strip or door bar — is a profile fitted at the base of a doorway where two different floor coverings meet. It serves three key purposes:

• Covers the expansion gap between two floor surfaces
• Creates a smooth, safe transition between rooms
• Gives a clean, professional finish to any flooring installation

Without a threshold strip, floor edges are left exposed, creating trip hazards and an unfinished appearance. Our range covers every common scenario — from same height transitions to ramp profiles for height differences.

Our Door Threshold Range

1. Aluminium Door Thresholds

Our aluminium door thresholds are the most popular choice for UK homeowners and trade fitters. Made from high quality anodised aluminium, these profiles are durable, corrosion resistant and available in multiple widths. Suitable for laminate, LVT, vinyl, 
tiles and hard floors — available in self adhesive and screw fix options.

2. Aluminium Wood Effect Door Thresholds

Want the strength of aluminium with the warm look of wood? Our aluminium wood effect door thresholds combine a robust aluminium base with a realistic wood effect finish. Perfect for oak floors, laminate and wooden floor transitions where you want a seamless, 
natural appearance.

3. UPVC Wood Effect Door Thresholds

Our UPVC wood effect door thresholds offer a lightweight, cost-effective alternative with a realistic timber appearance. Ideal for interior doorways where a wood finish is preferred 
without the cost of solid wood or aluminium.

4. Door Bars for Carpet

Specially designed carpet door bars hold carpet edges firmly in place at doorways, preventing fraying and lifting. Our carpet threshold bars provide a secure, neat finish where carpet meets any other floor surface — available in various widths and finishes 
to match your interior.

5. LVT Thresholds and Trims

LVT flooring requires precise threshold trims to finish edges cleanly at doorways. Our LVT thresholds and trims are specifically designed to complement luxury vinyl tile installations, providing a flush, professional finish that protects LVT edges from lifting or damage.

6. Threshold Strips for Wooden Floors

Wood floors expand and contract with temperature changes, making the expansion gap at doorways particularly important. Our threshold strips for wooden floors cover this gap neatly while allowing natural movement — protecting your floor investment and maintaining a clean finish.

7. Same Height Transition Strips

When two floor surfaces meet at exactly the same height — such as laminate to laminate or tile to tile — our same height transition strips provide a clean, flush join. These T-bar style profiles sit flat across the join, giving a seamless appearance with no height difference.

8. Transition Strips for Different Heights

Where two floors meet at different heights, a ramp profile is required. Our transition strips for different heights create a smooth, gradual slope between the two surfaces — eliminating trip hazards and providing a neat, professional finish. Suitable for height differences commonly found between laminate and carpet, or tiles and vinyl.

9. Wide Door Thresholds

For wider doorways or larger floor gaps, our wide door threshold strips provide greater coverage than standard profiles. Available in aluminium and wood effect finishes, these wider thresholds are ideal for double doorways, open plan transitions and anywhere a 
standard width strip would leave gaps uncovered.

How to Fit a Door Threshold Strip

Self Adhesive Fitting (Easiest Method):

1. Clean the floor surface thoroughly — remove dust, grease and debris
2. Measure the doorway width and cut threshold to length if required
3. Peel the adhesive backing strip carefully
4. Position the threshold accurately across the doorway
5. Press firmly along the full length for 30-60 seconds
6. Allow adhesive to bond fully before heavy foot traffic

Screw Fix Fitting (Most Secure Method):

1. Position the threshold and mark the fixing hole positions
2. Drill pilot holes into the subfloor
3. Secure with screws through the pre-drilled slots
4. Snap or press the cover cap into place if applicable
5. Check the profile is flush and secure before use

Frequently Asked Questions

What is the difference between a door threshold and a transition strip?

They are the same thing — door threshold, threshold strip, transition strip, floor transition strip and door bar all refer to the profile fitted at a doorway where two floor surfaces meet. The name varies by region and trade.

Can I fit a door threshold myself?

Yes — our self adhesive door thresholds are designed for easy DIY fitting with no specialist tools required. Simply peel and stick. Screw fix options are also straightforward for confident DIYers.

What width door threshold do I need?

Standard doorways typically suit a 41mm threshold. Wider gaps or double doorways may require a 61mm or wider threshold strip. Measure your gap before ordering.

Are your door thresholds suitable for underfloor heating?

Yes — our aluminium thresholds are compatible with underfloor heating systems. Aluminium conducts heat efficiently and will not warp or crack with temperature changes.

Do you offer fast UK delivery?

Yes — all orders are dispatched from the UK for fast, reliable delivery. Order before our daily cut-off for same or next day dispatch.
