FAQs

  • What are your patio doors made from?

  • We use Liniar’s premium ModLok patio doors, made from uPVC. UPVC (unplasticized polyvinyl chloride) is a strong but lightweight and low-maintenance material perfect for keeping the warm air in.

    UPVC is a great substitute for painted wood and a cheaper alternative to timber or aluminium. This is why uPVC patio doors are often available with a wood grain effect.
    Choose from a wide range of styles to suit your home, and then trust our experienced team to manage the project with minimum fuss.

  • What is the difference between PVC and uPVC?

  • PVC and uPVC are two vinyl materials used in the construction industry thanks to their durability and flexibility. However, despite what you may see online, PVC is not used to make doors due to its chemical composition. PVC is more commonly used for siding and fencing, whereas uPVC is used for windows and doors.

    UPVC is much more durable than PVC. UPVC doesn’t contain phthalates or BPA, making it a safer product for the environment, while still maintaining the benefits of a vinyl patio door frame.

  • Do uPVC patio doors warp in the sun?

  • UPVC expands and contracts slightly in more intense weather conditions. However, it's completely normal for windows and doors to swell during the hotter months.

  • Do uPVC patio doors fade?

  • UPVC patio doors can fade over time. This is usually due to sun exposure, and you’ll likely notice it more on south-facing doors. That being said, this happens over a long period of time, giving the colour of your uPVC doors a lifeline of around 15 years.

  • Do patio doors require maintenance?

  • Our Liniar ModLok patio doors are super easy to clean. If the inside gets a little grubby or dusty, all you need is a damp cloth and dish soap! A proper wash of the exterior twice a year will also do the trick. Always remember to keep your tracks nice and clear from debris too.

  • How much are your Patio Doors?

  • All of our designs and installations are completely unique and based on your preferences. This means prices can change when it comes to colour, style and other modifications such as handles.

    As a guideline, our Patio Doors start from £1,750. These are averages and don't include any bespoke changes. To find out more, speak to us today!
