uPVC Windows

Old timber and worn frames let cold air in and heat straight back out. A new uPVC window closes that gap, so your rooms hold their warmth through winter without extra heating. Double or triple glazing comes as standard, whichever level of insulation you need.

The window opens easily for ventilation on warm days and seals tight against wind and rain when the weather turns. The frame handles Hampshire’s damp winters without swelling, cracking or fading, year after year.

At BJH Windows, we survey, manufacture and fit every uPVC window ourselves. One team handles the job from your first appointment through to the final fit.

Our unique customer-centric process ensures every detail is handled with care, from consultation to installation. Discover why generations have chosen BJH Windows.

Designed to last

Built on Proven Materials

Every uPVC profile we fit comes from manufacturers who test their products against recognised UK standards for weather resistance, security and thermal performance. That testing happens long before the window reaches your door.

Our own installers fit every window we supply. The person who measures your opening works to the same standard as the person who chose your manufacturer.

Here’s what a uPVC window gives you over the years you own it:

  • Frames that don’t need painting, sealing or staining
  • No rot, warping or fading, even in exposed spots
  • Lower heat loss with double or triple glazing
  • Up to 70 per cent less outside noise coming through
  • Multi-point locking built into every window
  • A choice of tilt and turn or sliding sash, so the style fits your home

Bespoke options

What’s Included as Standard

Every uPVC window we fit is designed to meet our high standards, whatever size or style you choose. Our standard specifications include;

  • 70mm frame depth, strong enough to hold its shape without looking heavy
  • A++ energy ratings across the range
  • Double or triple glazing to suit your insulation requirements
  • 23 standard colourways, plus bespoke finishes on request
  • Woodgrain finishes that copy the look of timber grain and colour

High quality modern locking is never an optional extra. Every uPVC window we fit includes multi-point locking designed to meet PAS24 security requirements, so the protection is there from day one.

Colours, Sizes and Finishes

Your window opening has its own dimensions. We build to those measurements directly, so the finished window fits the space rather than the space being adjusted to fit a standard window.
Pick from 23 standard colourways, white and anthracite grey among the most requested. If your property calls for a period look, choose a woodgrain finish like Rosewood, Golden Oak or Irish Oak. Handle styles and glazing patterns can be adjusted too, so the finished window matches your home.

What Are The Benefits Of Choosing uPVC Windows?

uPVC windows, sometimes referred to as PVCu windows, offer long-term value and excellent performance. They do not require painting, sealing or staining, and they are easy to clean with just warm soapy water. These windows are weather-resistant and will not rot, which means they maintain their appearance and function for many years.

In addition to being low maintenance, uPVC windows are highly energy efficient. When paired with double or triple glazing, they help reduce heat loss and can significantly lower energy bills. They also provide excellent sound insulation, which can reduce external noise by up to seventy per cent, making your home quieter and more comfortable.

Our windows come with advanced security features, including multi-point locking systems, giving you peace of mind without compromising on style.
