Best Vinyl‍ End Vent Slider Windows  - Clera Windows + Doors

Windows and doors are an integral part of any home or office. Old, worn-out, and poorly-made products can result in uncomfortable drafts, not to mention a loss of heat which will translate to more money being wasted on energy bills. Windows and doors are also famously prone to condensation and frost, especially during Aylmer’s long cold winter months, increasing the probability of mould and further decreasing the lifespan of any given fixture. At Clera doors and windows, we have been designing, manufacturing, and installing quality, energy-efficient products that guarantee our clients in Aylmer can take advantage of increased levels of comfort, reduced condensation on the glasswork of their windows, lower energy consumption—leading to more manageable energy bills—and reduced levels of the noise and dust pollution which can often spill in from outside the building.

The doors and windows in Aylmer store are offered in a market-leading range of options. In order to make sure that every client will be able to find something that meets their needs, we’ve worked hard to provide a plethora of options. The valuable feedback of our clients is the fuel of our ongoing journey, and helps guide us as we manufacture doors in more than 10 different outlays, each of which can be further customized according to our customers’ wishes. Examples of options we provide include double or single tilt, end vent sliders, casement windows, awning windows, and low profile fixed windows, to mention but a few. In addition, we also lead the replacement doors in Aylmer and replacement windows in Aylmer markets.

Vinyl Windows and Doors

Vinyl is our favourite furniture material, given that it’s affordable, lightweight, and robust. It comes in a variety of different shades, like Aqua Blue, Midnight Black, Pearl White, Wheat Brown, Tangerine, and so forth. We prioritize the use of vinyl windows and doors since they last longer in comparison to doors and windows constructed from other, less optimal materials. In addition, vinyl products are easy to maintain, and boast industry-low rates of upkeep costs. Cleaning rarely requires anything more complicated than a once-over with warm, soapy water. Should that fail to do the trick, even the most resistant stains will be handled adequately with a mild detergent.

Another reason to opt for vinyl is its superb R-value rating, which it achieves on account of the fact that it doesn’t overheat easily, allowing more heat to be comfortably stored without risk of damaging the integrity of the material. This is the chief factor that contributes to vinyl’s reputation as a good insulator. Add to this impressive range of features their portability, and it’s easy to see why we prefer using vinyl whenever possible.

At Clera Windows and Doors, we offer an extensive range of vinyl windows, from casement and awning to single/double-slider tilt to single/double-hung tilt. We custom manufacture your replacement vinyl windows using our own sealed glass units, which make use of Hydraglass 50 warm edge technology on a Super Spacer platform.

We are an industry leader when it comes to energy-efficient doors and windows, with multiple recognitions across Canada and Energy Star certification on our entire range of products. This means that our products are the most energy-efficient on the market. Add to this the fact that we design and manufacture custom doors and windows for your specific needs, and you can clearly see why we have more than 40 offices across the country.

Our high performance vinyl windows will not only transform the look of your home and improve curb appeal, but also improve the security of your home, shield you from outside noise, and reduce your energy costs. Our windows also come with 100% pure virgin UPVC that protects from fading, which translates to zero maintenance for the entire length of service. So, if you have a requirement for vinyl doors in Aylmer, just give us a call and ask for a free estimate!
