Why choose our UPVC Windows

Modern UPVC windows are the most popular style in the UK.  They are characterised by outward opening vents which are combined with fixed panels (lights).  Mates Rates can manufacture almost any size and style!

The profiles are slim, but strong and insulating.  When combined with high quality glazing, they create a thermally efficient window which is robust and easy to maintain.

Because tastes and properties differ, Mates Rates casements are available in either a chamfered or ovolo shape.  There is also an extensive range of colours, glazing and hardware options available.

UPVC stands for “unplasticized polyvinyl chloride.” UPVC windows are made from a rigid and durable form of PVC. They are energy-efficient, low-maintenance, and provide excellent insulation for your home. UPVC windows are popular due to their ability to withstand various weather conditions and their long-lasting properties.

The cost of UPVC windows can vary depending on the size, style, and features you choose. Generally, UPVC windows are more affordable than other window materials like wood or aluminum. To get an accurate quote, we would need to assess your specific requirements and measurements.

UPVC windows are known for their durability and can last for several decades with proper care and maintenance. On average, you can expect UPVC windows to have a lifespan of around 20 to 30 years or even more.

You can choose from 16 different colours for your windows. We offer: AnTeak, Black & Brown, Blue, PVC-U White, Cherrywoof, forest green, UPVC grey windows, Mahogany, Chartwell green, Rustic cherry, Golden oak, Irish oak, Red, Woodgrain brilliant white, Woodgrain white and cream.

The terms UPVC and PVC are often used interchangeably, but there is a slight difference.

UPVC windows are made from unplasticized polyvinyl chloride, which is a more rigid and durable form of PVC. Regular PVC windows are softer and more flexible, making UPVC windows more suitable for long-term use in window installations.

Yes, it is possible to fit UPVC windows into existing wooden frames.

However, this process requires careful installation and may involve removing parts of the wooden frame to accommodate the UPVC windows properly.  It’s essential to have a professional assess the condition of the wooden frames and provide appropriate guidance.

UPVC windows come in a variety of colours, so painting them is generally not necessary.

However, if you still wish to change their colour, it is possible to paint UPVC windows. Keep in mind that this may void the manufacturer’s warranty. You should also use the appropriate type of paint designed for UPVC surfaces.

Our UPVC windows come with adjustable hinges, which allow for simple adjustments.

If your UPVC windows are not closing properly or are letting in drafts, you can usually make minor adjustments to the hinges.

If you are struggling, get in touch, our expert team of professional window technicians will be happy to handle any significant adjustments to ensure adjustments are done correctly.

To hang net curtains on UPVC windows, you can use self-adhesive hooks or tension rods that fit within the window recess.

These options are convenient and do not require drilling holes into the window frames, preserving the integrity of the UPVC material.

Cleaning UPVC windows is relatively easy. You can use a mixture of mild soap and water to wipe down the frames and glass.

Avoid using harsh chemicals or abrasive materials that could damage the UPVC surface. A soft cloth or sponge is sufficient for regular cleaning.

If you have yellow stains on your window simply make up a mild solution of warm water and dish soap. Gently scrub the stains with a soft cloth or brush. Rinse thoroughly and repeat if needed. Dry with a soft cloth to prevent water spots. Use specialized UPVC cleaners if necessary. For ongoing maintenance, regularly wipe down the windows to prevent future stains and keep them looking fresh.
