Joinery Styles

No matter what style you’re looking for, our range of sliding sash windows is sure to compliment your property perfectly. Our sliding sash windows come with a variety of joinery options, including run-through sash horns, invisible joints on a seamless weld, and our signature Bison-style corners with mechanical joints.

To further complement our sliding sash windows, we also offer a variety of matching trims and accessories. We also provide various colours to enable customers to design their perfect traditional or modern Huddersfield home.

Security Options

Having a secure and well-functioning home is important. D&I offers sliding sash windows that have been certified according to PAS24 security requirements for various types of invasions. Strengthen the windows’ defence by choosing laminated glass for extra protection against burglaries and outside objects.

Our sliding sash windows are designed with safety in mind, so you can rest assured that your children and pets can remain safe and secure when the window is open. To provide even more protection, we offer travel restrictors to make smaller apertures for your children and pets. That way, you never have to worry about the safety of your windows in Huddersfield!

Energy Ratings

Our sliding sash windows feature double glazing which, with an “A” energy rating, helps to conserve energy efficiently. Furthermore, draughts and wind-induced weather stays outside due to the addition of gaskets running along the window edge and brush pile seals situated between the sashes.

If you’re looking for low-maintenance window solutions that are also completely weatherproof in Huddersfield, uPVC is the ideal choice. Here at D&I, we offer sliding sash windows that require minimal effort to keep looking their best. All you need to do is wipe them down with a cloth regularly. This can make a big difference when it comes to ongoing home maintenance.


At D&I, we believe in sustainability. That’s why our uPVC doors and windows are designed to endure, with some of our frames lasting up to 25-30 years. However, when their service is over, we provide options for eco-friendly disposal and supporting responsible recycling efforts.

Replacing your windows with uPVC is both an economical and environmentally friendly choice. This material has amazing strength and durability, and it can even be recycled again and again, eliminating any waste. By recycling your sliding sash windows, you are not only lengthening their lifespan, but you are also doing your part for the environment. Choose a material that will last for generations, like uPVC!
