Composite Doors in Rossendale & Lancashire: Solidor vs Rockdoor vs Cannon Door

A front door has to do a lot in this part of Lancashire. It needs to stand up to the rain that comes over the Pennines, keep the heat in on a stone-built terrace, and look right on everything from a Victorian semi in Rawtenstall to a new-build in Bury. That's why composite doors have become the default choice for so many homeowners. But "composite door" covers a wide range of products, and the three brands we fit (Solidor, Rockdoor and Cannon Door) are built in different ways.

This guide explains what a composite door actually is, how the three brands differ, and what to ask before you choose.

What is a composite door?

A composite door is made from a combination of materials rather than a single one like timber or uPVC. Typically that means a strong inner core, an insulating layer, and a tough outer skin, usually glass-reinforced plastic (GRP), with a woodgrain or smooth finish. The aim is to combine the look of a painted timber door with much better insulation, security and weather resistance, and far less maintenance.

Composite doors don't need painting, won't warp or swell like timber, and can be made in a wide range of colours with matching or contrasting frames.

Solidor, Rockdoor and Cannon Door: how they differ

All three are established UK composite door brands, and all are made to measure. The differences are mainly in construction, design range and features. Exact specifications change from time to time, so we'll always show you the current brochure and samples at survey.

Solidor

Solidor doors are built around a solid timber core inside a composite skin. That gives a reassuringly heavy, solid feel and a deep, traditional look. The range includes classic cottage, Georgian-style and contemporary designs, plus matching side panels, French doors and stable doors. Solidor is well suited to period terraces and traditional stone properties where you want a proper "front door" feel.

Rockdoor

Rockdoor has been making composite doors since 1996 and describes itself as "the original composite door". Rockdoors are made to measure rather than cut down from stock sizes, and are built with a reinforced inner frame and multi-point locking. The range leans towards bold and distinctive designs with a wide choice of glass. It's a popular choice for homeowners who want a door that's a statement as well as secure.

Cannon Door

Cannon Door offers composite doors in a broad range of styles, from traditional to modern, with options for glazing, colours and hardware.

Rather than one brand being "best", each suits different homes and budgets. We'll recommend based on your property, your priorities (security, look, glazing, budget) and what's available in the colours you want.

What to look for in any composite door

Whichever brand you choose, these are the things worth checking:

• ▸Security accreditation. Look for PAS 24 and Secured by Design where available, a multi-point lock, and anti-snap cylinders, ideally to TS 007 3-star or SS312 Diamond standard.
• ▸Thermal performance. For a replacement door in England, the whole door should meet the Building Regulations limit (a U-value of 1.4 W/m²K or better, or the equivalent energy rating). Ask for the figure for the specific door and glass you've chosen.
• ▸Glass. Decorative and obscure glass options vary between brands. Any glazing in a door must be safety glass.
• ▸Frame. The frame matters as much as the slab. Check what frame is supplied and how it's finished in your colour.
• ▸Thresholds. A low threshold makes access easier for buggies, wheelchairs and older relatives. Ask what's possible on your property.

Composite doors for Rossendale's stone terraces

Much of the housing in Rossendale, Burnley, Rochdale and Bury is solid stone or brick from the late 19th and early 20th centuries, often with openings that aren't perfectly square and reveals that have moved over a century. A made-to-measure door, fitted by an installer who surveys properly, makes a real difference here. We measure each opening individually, check the condition of the step and lintel, and advise on traditional designs, colours and furniture that suit the character of the street. That matters even more in conservation areas, where your local authority may have views on how a front door looks.

Composite or aluminium front door?

If you want a traditional or cottage look with a warm, solid feel, a composite door is usually the best fit. If you're after a very contemporary, architectural entrance with large glazed panels, slim sightlines or an oversized pivot-style door, look at our luxury aluminium entrance doors. We fit both, so we can give you an honest comparison for your property.

Frequently asked questions

Which composite door brand is best?

There's no single best brand. Solidor's solid timber core suits traditional homes. Rockdoor is known for made-to-measure construction, security and bold designs. Cannon Door offers a broad range with good all-round value. The right choice depends on your property, the look you want and your budget.

Are composite doors more secure than uPVC doors?

Composite doors are generally thicker and more solid than standard uPVC doors and come with multi-point locking. Whatever the material, check for PAS 24 accreditation and an anti-snap cylinder.

Do composite doors need building regulations approval?

Yes. Replacing an external door in England is notifiable. An installer registered with a Competent Person Scheme, such as Assure, can self-certify it for you.

How long does a composite door last?

A good-quality composite door should last for many years with very little maintenance. Check the manufacturer's guarantee for the door, finish and locks of your chosen brand.

Do you fit composite doors outside Rossendale?

Yes. We fit composite doors across Rossendale, Burnley, Rochdale, Bury, the Ribble Valley and Greater Manchester.
