UPVC Windows & Doors

If you're looking for energy-efficient, low-maintenance windows & doors that look great and last for years, you've come to the right place. At ALI-PRO UK, we supply and install high-quality UPVC windows and doors across Exeter and the South West and we've been doing it for over 19 years.

UPVC Windows

UPVC windows are one of the most popular choices for homes and businesses across the UK and it's easy to see why. They're tough, thermally efficient, and virtually maintenance-free.

Here's what makes them so great:

Excellent insulation — keeps your home warmer in winter and cooler in summer
Very low maintenance — no painting, no warping, no rotting
Strong and secure — modern UPVC frames come with multi-point locking as standard
Long-lasting — with proper installation, UPVC windows can last 20–35 years
Cost-effective — great value compared to timber or aluminium

Our UPVC Window Styles

We offer a wide range of UPVC window styles to suit all types of properties, from period homes to modern new builds:

Casement Windows

The most common window style in the UK. They open outward on a hinge and come in a huge range of configurations. Clean, classic, and very practical.

Sash Windows

Perfect if you want the traditional look of a sash window with the durability and low maintenance of UPVC. A popular choice for older or period-style homes.

Tilt & Turn Windows

A versatile option that can tilt inward for ventilation or open fully for easy cleaning from inside. Great for upper floors and apartments.

Bay & Bow Windows

Add space and character to any room. We can design and install bay and bow configurations to suit your home perfectly.

UPVC Doors

As well as windows, we also supply and install a great range of UPVC doors. Whether you're looking to replace a tired front door or add a back door that's more secure and better insulated, we've got you covered.

Composite & UPVC Front Doors

Your front door is the first thing people see, so it needs to look good as well as perform well. Our UPVC front doors come in a wide range of styles, colours, and glass designs — so you can find something that suits your home perfectly. Strong, draught-proof, and fitted with multi-point locking as standard.

Back Doors & Side Doors

A well-fitted UPVC back door makes a big difference to your home's security and heat retention. We offer a range of panel and half-glazed options to suit different needs and budgets.

French Doors

Want to open up your living space to the garden? UPVC French doors are a cost-effective way to get that open feel. They look great, insulate well, and are much more affordable than aluminium equivalents.

Patio Doors

UPVC sliding patio doors are a practical and popular choice for accessing the garden. They take up no swing space and let in plenty of light ideal for smaller gardens or terraces.

Double Glazing as Standard

All our UPVC windows come with double glazing as standard. This means a sealed unit with two panes of glass and an insulating gap between them reducing heat loss, cutting energy bills, and reducing outside noise. We can also offer triple glazing if you want maximum efficiency.
