What You Need to Know About uPVC Windows

Picture this: It’s the middle of winter, and you’re spending your Friday evening replacing the weatherstripping on your living room windows. For the seventh time.

Sound familiar? If so, it’s time to get some new windows in your life! Do yourself a favor and stop repairing windows that were ready to be replaced eight repairs ago.

If your current windows are wood, you might want to consider uPVC windows for your upgrade. It’s important to note that uPVC is a low thermal conductivity material, helping to keep your home warmer in the winter and cooler in the summer.

Plus, uPVC is a popular choice for homeowners looking for windows that are both durable and energy-efficient. Read on to learn more.

What Is uPVC?

UPVC stands for “unplasticized polyvinyl chloride” — commonly known as uPVC. You might also hear it referred to as rigid PVC because it’s less flexible than normal PVC.

It’s BPA and phthalate free, which is important for your health because BPA can lead to adverse behavioral effects on the brain.

It’s also becoming more and more popular. While contractors have known about uPVC’s strength and energy efficiency for decades, homeowners typically shied away from it due to its less than appealing aesthetics. Modern uPVC window manufacturers, however, have found ways to make the material super attractive.

Today, uPVC windows offer the best of both worlds — durable and easy on the eye. Plus, you’re looking at a material that’s low-maintenance and extremely durable, making it a smart choice for any home.

Why Should Homeowners Choose uPVC?

There is a slew of benefits for uPVC windows, but we’ll name just a few.

First of all, uPVC windows won’t rot, rust, or warp. UPVC window repairs simply aren’t a thing — they’re that durable and require very low maintenance.

They’re made from waterproof materials, which helps them hold up to the elements. UPVC windows are termite and fire resistant, too.

They’re also colorfast — they won’t fade or peel like paint on a wooden window. Even if the uPVC is scratched, it’s the same color underneath, so it’s not noticeable at all.

Plus, uPVC windows are designed to withstand the test of time, offering beauty and durability that lasts for years.

Finally, they’re super airtight. Your savings on heating and cooling will offset the uPVC window cost in no time. This is also a huge plus for homes with HVAC systems, too, since they help keep dirt and dust out of your home.

What About Wood Frames?

Wood window frames have a certain classic look to them that most homeowners love. You might think you have to sacrifice that look for the durability of wood windows. Guess what: You don’t.

Timber windows may offer charm, but premium uPVC windows can be made to look unidentifiable from wood — combining style with strength. This is ideal because wood windows are a thing of the past now.

For even more versatility, tilt and turn windows made from uPVC give you the classic look you want with the added benefit of modern functionality.

Wood will contract and expand according to the weather, leading to expensive and frequent repairs. It also needs to be painted regularly to keep your windows looking fresh. It’s fire-catching and prone to termite damage, too.

Don’t sacrifice your home’s quality for the look of wood windows when you can have it all — durability, beauty, and low maintenance.
