Solid Wood Renewable and recyclable, boards can be a real plus when it comes to selling a house. However, solid wood may move and curl if used in a kitchen, as it's both moisture and heat sensitive. 'Decide how inert you want the floor to be,' says John Davies at Plastik Architects. 'Solid wood will change over time, so if you want your floor to stay the same, choose other materials.' Wooden floors can be finished in polyurethane lacquer, or natural linseed oil, which sets hard, seals and protects the wood. Most sealants will stand up to many years of traffic before they need reapplying. Choose any gloss level, but be aware that high gloss tends to show marks. 'Uniform boards give a modern look,' says Steve Maltby of Junckers. 'Boards with knots are more rustic.'
Engineered Boards Constructed from multiple layers, engineered wood usually has a softwood or plywood base and a wood or wood-effect top layer. 'Water and wood are never a good combination, but whereas solid wood may gape or warp, engineered boards have a central core that stops the top and bottom layers moving,' explains Bill Worman at Element 7. Although engineered boards can feel less solid, they come in a variety of widths and finishes and are perfect for achieving a natural wood look.
Laminate Flooring Laminate flooring is made up of synthetic materials combined with natural and recycled ingredients. It comes in a number of formats, colours and designs, including wood, stone and tile. And companies such as Pergo have now introduced laminate with antimicrobial and antistatic properties, which are ideal for kitchens. It's super-durable – resistant to staining, wear and fading – making it perfect for high-traffic areas. Prices vary hugely, but you get what you pay for – choosing cheap laminate may result in ill-fitting, bouncy boards and will always be a false economy.
Cork A long way from the curly orange tiles of the Seventies, modern cork flooring is available in a wide range of colours, designs and finishes. Tough and naturally antibacterial, it's great for people with allergies, too. 'There are an amazing 40 million cells of air in every cubic centimetre of cork,' says Paul Heatley from cork flooring company Wicanders, 'which makes it very comfortable underfoot. It also has exceptional acoustic benefits.' Cork is harvested without damaging the tree. In fact, removing the bark means the trees live longer.
Bamboo With a higher fibre rating than any hardwood, bamboo is incredibly durable and is less likely to gape than other solid woods. Usually pretreated by the manufacturer, it can be stained or left its natural colour, then sealed with a gloss or matt lacquer. Bamboo releases 35 per cent more oxygen into the atmosphere than trees, and is a fast-growing grass, so it can be harvested every 3-5 years, making it a very eco-friendly product.
