Our hands-on approach to manufacturing and installation means that we are there every step of the way to make sure your windows and property are treated with the highest level of care. Slimline aluminium windows can be paired with our range of ancillaries, which come in over 200 RAL colour options so that you can make your home truly unique. From bespoke door handles to locks, hinges and peg stays, we can make your home as cohesive as it is beautiful.

The benefits of slimline aluminium windows

The benefits of slimline aluminium windows go beyond kerb appeal, granting a host of advantages over uPVC that cover everything from energy efficiency to security. Aluminium slimline windows are much thinner and much more durable than uPVC, meaning you get all the benefits of a larger viewing area with the added resistance to weather conditions.

Our windows are secure and PAS24-rated, with a modern multipoint locking system for peace of mind. Aluminium slimline windows come in double and triple-glazing options, keeping your home warmer for longer.

Versatile frame options

Our frames come with a range of complimentary ancillary options, such as colour-matched door handles that fit the aesthetic of your windows and property.

Made in-house, our frames come in many different styles, from shaped to sash, curved and our Benenden Conservation Slimline range.

Let us know if you have any particular frame style in mind or if you’re unsure which would best suit your home. We can design top-hung, tilt and turn and fixed-style windows that perfectly fit the shape of your home.

Customisable design

Fully customisable, our windows have 200 RAL colour options to choose from, our own complimentary ancillaries and bespoke design alterations and configurations.

Combine these different options in a way that caters to your dream project, such as deep blacks for an art-deco period property restoration or brighter colours for a modern twist.

Superior glazing

Once you’ve decided on your frames, choose either double or upgrade to triple-energy-efficient glazing options for superior thermal control, thickness, solar control and noise insulation.

Thanks to their thin profile, our frames reduce condensation build-up compared to typical uPVC windows – helping to keep your home warmer.
