What are the benefits of Timberlook bay and bow windows for my Winchester home?

Choosing new windows raises plenty of questions, especially when your home has period character to protect. Here are the answers Winchester homeowners ask us for most.

Upgrade Your Winchester Home with Timberlook Bay and Bow Windows

Are these windows suitable for period properties in Winchester?

Many Winchester homes sit in conservation areas where appearance matters. Timberlook windows were developed precisely for these situations, with flush frames, authentic joints and heritage details that planners and neighbours recognise as sympathetic. We always recommend checking with the local authority first, and our team can support you with the details you need.

How do bay windows differ from bow windows?

Bay windows project from the wall in a series of flat sections, typically three, while bow windows form a continuous curve from four or more sections. Both flood a room with light and add a real feeling of space. The right choice usually comes down to the age and style of your home, and we manufacture both.

What makes Timberlook bay and bow windows different from traditional timber windows?

Timberlook bay and bow windows are made from uPVC but engineered to replicate timber joinery in fine detail, right down to the flush finish and authentic joints. You get the warmth and character of wood without the sanding, painting and swelling that timber needs, plus far better thermal performance.

How does Timberweld technology improve these windows?

Timberweld joins the frame corners so they look hand crafted, like classic timber joinery, while remaining completely sealed against the weather. It combines the precision of modern welding with the aesthetics of traditional carpentry, which is why it sits at the heart of every Timberlook window.

Will new bay and bow windows reduce my heating bills?

Yes. Our bay and bow windows achieve U values as low as 1.2 W/m2K, a significant step up from single glazed timber or early double glazing. Better insulation means less heat escaping through what is often the largest glazed area in the house, helping to keep heating bills down.

And where in the country do you offer your Bay and Bow Windows?

    Cills

    Choosing the right cill for your Timberlook windows

    We offer a choice of cill options to enhance your bay and bow windows. Choose between the contemporary shallow cill that comes as standard or the Radlington Cill which has been designed to add a sophisticated charm to any property.

    85mm Stubb Cills

    These small but strong cills are often used for properties with stone cills, having been crafted to ensure that moisture is directed away from the frames, removing the risk of water ingress.

    150mm Cills

    As the industry’s ‘standard’, these cills protrude 80mm from the front of the frame. They offer long lasting protection, are virtually maintenance free, and come in a choice of colours.

    180mm Cills

    The 180mm cill is the largest cill we offer, protruding 110mm from the front of the frame. You’ll often find these cills in properties with frames that are recessed in the brickwork.

    Radlington 165mm

    Cills are usually 30mm deep, but to accurately emulate traditional looking frames, the Radlington cill is slightly thicker at 55mm deep, protruding 95mm from the face of the frame.

    Hardware

    Quality hardware to compliment your home

    As standard, our bay and bow windows are equipped with contemporary handles. However, you can customise them even further with our Premium Regency furniture. You have the option to choose from Peardrop and monkey-tail handles to give your windows a unique touch.

    Standard Handles

    Our sleek window handles fit perfectly with Timberlook windows and won’t interrupt views. They are available in a wide range of colours to perfectly match our windows, and offer smooth and comfortable operation.

    Monkey Tail

    Inject distinctive character and timeless elegance into Timberlook windows with monkey tail handles. These elegant and durable handles add a touch of vintage charm while providing reliable functionality.

    Pear Drop

    Transform the look of Timberlook windows with classic and ornate pear drop handles. These handles combine timeless aesthetics with practicality, enhancing the beauty and functionality of our flush casement windows.

    Peg/ Dummy Stays

    Decorative and functional peg/dummy stays not only add a touch of charm to our Timberlook flush casement windows, but also provide sturdy support, improving the overall window experience.
