Internal Softwood and Hardwood Linings

Shop internal softwood and hardwood linings for fitting internal doors throughout the home. Our range includes universal softwood door linings, redwood linings, loose-stop options, white primed linings and door-pair linings in a choice of sizes.

A correctly fitted door lining creates the surround within the wall opening and provides the structure needed to hang an internal door. Choosing the right lining depends on the size of the opening, wall depth, door arrangement and the finish you want to achieve.

Whether you are replacing an existing internal door, renovating several rooms or fitting doors throughout a new project, check the dimensions and individual product details carefully before ordering.

Softwood Door Linings

Softwood door linings are a popular choice for standard internal doors and provide a practical solution where the finished lining will be painted or otherwise decorated.

Softwood is relatively easy to work with during installation and can provide a cost-effective choice when several internal doors and linings are being fitted as part of the same project.

Our collection includes universal softwood door linings as well as softwood door-pair linings for suitable double-door arrangements.

Always check the dimensions of the individual lining set before ordering, particularly the lining depth and the size of door or opening it is intended to accommodate.

Redwood Door Linings

Redwood provides another timber option for internal door linings. Our range includes internal redwood door linings supplied with loose stops as well as redwood linings designed for pairs of internal doors.

Unfinished redwood can be finished to suit the surrounding interior, making it a versatile choice for renovation work and new internal door installations.

If the natural timber will remain visible, select an appropriate finish for the appearance you want to achieve. Where the lining will be painted, prepare and finish the timber in accordance with the product manufacturer’s recommendations.

White Primed Internal Door Linings

White primed door linings provide a convenient starting point where a painted finish is planned. The primed surface reduces some of the preparation required before applying the final decorative finish.

Our collection includes an Internal White Primed Door Lining supplied with a 14x25mm loose stop, together with an Internal White Primed Softwood Door Lining supplied with the same size loose stop.

These options work particularly well with white primed internal doors or interiors where the door, lining and architrave will eventually share a coordinated painted finish.

What Is a Door Lining?

A door lining is the timber surround fitted within an internal doorway. It normally consists of two vertical sections, or jambs, together with a head across the top.

The internal door is hinged to the lining, while a door stop provides the surface against which the closed door sits. Architrave can then be fitted around the opening to cover the joint between the lining and surrounding wall.

Although the terms door frame and door lining are sometimes used interchangeably, a lining is particularly common for internal doors and partition walls.

Internal Door Linings With Loose Stops

Selected door linings in our range are supplied with a loose door stop. Rather than having the stop permanently positioned before installation, a loose stop can be fitted in the required position as part of the installation process.

This can be useful when fitting and aligning an internal door because the position of the stop can be established in relation to the hung door.

Not every lining set necessarily contains the same components, so check the individual product listing to confirm whether a loose door stop is supplied.

Universal Internal Door Linings

Our range includes universal softwood door linings for suitable internal door installations.

The term universal describes the particular design of the lining, but it does not mean that one lining will fit every wall thickness, door width or opening. The actual product dimensions still need to be checked before ordering.

Measure your opening and wall carefully and compare these measurements with the lining set specification to determine whether it is suitable for your project.

Door Pair Linings

If you are fitting a pair of internal doors, you may need a wider lining designed specifically for a double-door arrangement rather than a standard single-door lining.

Our collection includes redwood pair linings as well as universal softwood door-pair linings. Softwood pair lining options include 108mm and 133mm products, giving you a choice according to the requirements of the opening.

Check the overall dimensions of the doors and lining before ordering. If the two doors require additional components to form the meeting point between the leaves, these should also be considered when planning the complete installation.

Choosing the Correct Door Lining Depth

Lining depth is an important measurement because the lining needs to work with the thickness and construction of the surrounding wall.

Measure the complete wall thickness at the doorway, including the relevant finished surfaces, and compare this measurement with the dimensions given for the lining.

Do not assume there is one standard internal door lining thickness. Different properties and wall constructions can require different lining depths, and the products within the range are available in different sizes.

Choosing a Door Lining for Your Internal Door

Start by identifying whether you are fitting a single internal door or a pair of doors. This determines whether you need a standard lining set or a door-pair lining.

Next, measure the opening and wall depth carefully. Check the lining dimensions against the door and opening rather than choosing purely by the nominal door size.

Then consider the required finish. Softwood and redwood provide versatile timber options, while a white primed lining can be particularly convenient when the finished frame will be painted.

Finally, check the components supplied. If you want a lining with a loose door stop, confirm that one is included with the particular product rather than assuming every lining set contains one.

Softwood vs Hardwood Door Linings

Softwood and hardwood describe broad groups of timber rather than a guaranteed level of hardness. Some hardwood species can be relatively soft, while some softwoods can be comparatively hard.

For internal door linings, softwood is commonly chosen where practicality, ease of finishing and value are priorities. It is particularly suitable where the lining will eventually receive a painted finish.

Hardwood can be considered where the appearance of the natural timber is more important or where a particular hardwood finish is required to coordinate with the door and surrounding joinery.

The best option therefore depends on the particular lining product, required finish, dimensions and intended installation rather than simply choosing hardwood because it is assumed to be stronger.

What About Oak Door Linings?

If you specifically want an oak finish, browse our dedicated range of oak internal door frames and linings for options designed to complement oak internal doors.

Keeping oak linings within their dedicated collection also makes it easier to compare the available finishes and dimensions without mixing them with standard softwood and redwood options.

What About Fire Door Linings?

Standard internal door linings should not automatically be used with a fire door. Fire door installations have specific requirements covering the door, lining or frame, intumescent seals and compatible hardware.

If you are fitting an FD30 internal fire door, browse our FD30 internal fire door linings and intumescent strips rather than selecting a standard internal lining.

Installing Internal Door Linings

Accurate installation helps an internal door open and close correctly. The lining needs to be assembled and positioned square, level and plumb within the opening before the door is hung.

Any adjustments or cutting should take account of the dimensions of the particular lining set and the requirements of the opening. Timber products should also be stored, handled and finished in accordance with the manufacturer’s instructions.

If you are unsure about measuring or installing a lining, an experienced joiner or door fitter can help ensure the lining and door are correctly aligned.

Frequently Asked Questions

What Is the Difference Between Softwood and Hardwood?

Softwood and hardwood are classifications based broadly on the type of tree the timber comes from rather than simply how hard the wood feels. For door linings, softwood is commonly selected for practical internal installations and painted finishes, while hardwood may be chosen where a particular natural timber appearance is required.

What Type of Wood Is Best for Internal Door Linings?

There is no single best timber for every internal door. Softwood and redwood are practical choices for many standard internal doors, particularly when the lining will be painted. The right choice depends on the required dimensions, finish, door arrangement and your project.

How Thick Is an Internal Door Lining?

Internal door linings are available in different depths and dimensions, so there is no single thickness suitable for every doorway. Measure the wall and opening and compare those measurements with the individual product specification before ordering.

Does a Door Lining Include a Door Stop?

Some do. Several products in this collection are supplied with a loose door stop, including selected redwood and white primed linings. Always check the individual product details to see exactly what is supplied.

Can I Get a Door Lining for a Pair of Internal Doors?

Yes. Our range includes redwood and softwood door-pair linings for suitable double internal door arrangements.

Can I Paint a Softwood Door Lining?

Yes. Softwood door linings are commonly used where a painted finish is required. Prepare and finish the timber using products suitable for the particular lining and follow any manufacturer instructions supplied.

Can I Use These Linings With Fire Doors?

Do not assume a standard internal lining is suitable for a fire door. If you are installing an FD30 fire door, choose an appropriate FD30 fire door lining and the required intumescent seals and hardware.
