    Double glazed windows with integrated blinds

    Integral blinds are securely slotted within the two panes of glass in a window. They have become a popular addition to new windows and doors with homeowners across the UK for a number of reasons. As they're placed within the window itself, they aren't exposed to the outdoor elements so won't require any maintenance. They'll stay in prime condition without gathering dust or fading, thanks to anti-fade colouring. Our integral blinds are compliant with industry safety campaigns and bodies, making them an excellent choice for homeowners with young children or animals.

    Another benefit of incorporating integral blinds is that they provide an easy way to control your home's temperature and privacy. With either a slider or cordless slider option, you can simply choose when to let the natural light in to brighten the room, or when you'd like more privacy.

    We offer a number of blind styles in a range of colours to suit any style of room's appearance. You can choose from horizontal or pleated styles. If you're considering adding integral blinds to your replacement windows, what about also including them into bi-fold doors or your conservatory for a consistent style across your home?
