Composite Cladding: Why It's Quietly Replacing Timber on UK Homes
The Shift Away from Timber Cladding
Timber cladding looks beautiful for the first two years. Then comes the silvering, the cracking, the algae streaks, and the annual sanding-and-staining ritual. Increasingly, UK homeowners and architects are choosing composite cladding instead - the look of wood, none of the upkeep.
What Is Composite Cladding?
Composite cladding is made from a mix of recycled wood fibre, recycled plastic, and bonding polymers. The boards are extruded into wood-look planks with realistic grain embossing. Premium grades are 'capped' - wrapped in a tough polymer shell that resists fading, staining, and impact.
Why It's Outperforming Timber
No rot - it doesn't absorb water, so fungus can't take hold. No annual treatment - no oil, no stain, no sanding, no varnish. Colour stability - capped composite holds its colour for 15-25 years. Insect resistance - termites and woodworm can't digest it. Recyclable content - typically 50-95% recycled material by weight.
Cost Comparison
Softwood timber cladding: £25-£50/m² installed, plus £200-£500 every few years in treatment and labour. Cedar cladding: £80-£140/m² installed. Composite cladding: £60-£110/m² installed, then almost zero ongoing cost. Over a 20-year window, composite is consistently the cheapest option of the three.
Style Options
Modern composite ranges include smooth-finish boards, deeply embossed wood-grain boards, fluted and ribbed profiles, charred wood (yakisugi-style) finishes, and a full palette from light oak through to deep charcoal. Many ranges use a tongue-and-groove or shadow-gap system that hides fixings entirely.
Where to Use It
Full-house exterior cladding, garden room and outbuilding exteriors, gable accent panels, porch and entrance feature walls, fence panels and screening, and even interior feature walls in industrial-style spaces.
Installation Notes
Composite cladding fits to timber or aluminium battens with hidden clips or screws. It expands and contracts slightly with temperature, so installation requires the correct expansion gaps at each board end. Always follow the manufacturer's spacing recommendation - typically 3-5mm per metre of board length.
Sustainability
Because composite cladding uses recycled wood waste and recycled plastic, it diverts material from landfill. Many ranges are themselves recyclable at end of life. For homeowners prioritising sustainability without giving up performance, composite often beats virgin-timber cladding on lifecycle carbon.
