Making your dream home a reality
Creating an open‑plan living space is a popular choice for many homeowners, whether by extending the property to add a kitchen extension or by combining existing rooms into one spacious area.
At National Plastics, we supply everything you need to bring your dream kitchen extension to life - from sleek aluminium bifold doors and stylish roof lanterns to a wide range of high‑quality roofline products.
Explore our product ranges in more detail and discover how National Plastics can take the hassle out of sourcing everything you need for your kitchen extension project.
Windows & Doors
Transform your kitchen extension with stylish bifold doors and expertly crafted windows designed to maximise light and space.
Our PVC‑u and aluminium bifold doors create a seamless link between home and garden, offering unobstructed views and open spans of up to 6.5 m, with configurations to suit your needs.
Complement your doors with our made‑to‑measure PVC‑u and aluminium windows, available in Casement, Tilt & Turn and Vertical Slider styles. With a wide choice of colours, hardware and glazing, you can ensure your windows and doors suit your home perfectly.
Roofing
Our aluminium and PVC‑u roof lanterns combine sleek, modern design with excellent performance. With fewer bars to maximise natural daylight, high thermal efficiency and easy clip‑on features for quick installation, they’re an ideal choice for any flat‑roof extension.
Pair them with our maintenance‑free EPDM rubber roofing - a durable, one‑piece membrane that won’t crack, split or rot. Simple to install without specialist tools, and supported by a full range of adhesives, trims and seals available at your local National Plastics branch, it offers long‑lasting protection against the elements.
Roofline
We supply a comprehensive range of high‑quality plastic roofline products to enhance and protect your kitchen extension.
Choose from an extensive selection of guttering systems with a variety of flow rates to suit your project. Find the perfect style to complement your extension.
Our fascias and soffits come in classic white or black, as well as popular shades like anthracite grey, with smooth or woodgrain finishes to match your windows and doors.
Enhance your extension with external cladding that boosts thermal efficiency and adds a modern finish. Choose from wood‑textured, woodgrain‑effect or clean white shiplap for a durable, stylish exterior.
Decking
No kitchen extension feels complete without considering the outdoor space. A decking area extends your living space seamlessly, optimising open‑plan living.
Our eco‑friendly composite decking offers the look of timber without the upkeep. Available in two low‑maintenance styles - reversible ribbed/grooved boards or woodgrain‑effect boards available in five colours.
Use our handy calculator to work out how much decking you need for your project.
Our Gallery
Our range of windows and doors, including light‑enhancing bifold doors, helps you create a bright, open kitchen extension with a seamless sense of flow. To extend that space outdoors, our composite decking pairs perfectly with our roofing, cladding and guttering solutions - offering everything you need to complete your extension beautifully and built to last.
