Buyer's Guide

Types of Windows

From modern to classic styles, we have a wide range of expertly crafted and visually-stunning vinyl windows that are easy to clean. Explore your options below!

Window Materials

Clera’s windows are made from vinyl to ensure they’re always safe, lead-free, and require minimal care to keep in tip-top condition. All our windows are manufactured using durable, 100% pure uPVC (unplasticized polyvinyl chloride or vinyl).

Vinyl windows are also more affordable than wood windows because wood designs are more difficult to manufacture. That said, vinyl cannot duplicate the allure of natural wood, so consider something that mimics it if you really want that look!

Security Features

Sturdy windows and doors made from high-quality materials are your first line of defence against burglars—safety should always be a priority. The good news is that Clera gives you options. You could opt for a door with an automatic locking function so your door stays shut once it closes. Purchasing windows made with wet-glazed frames or with stronger hardware and shatter-resistant glass can also help protect against potential intruders.

Maintenance Requirements

Your windows and doors should keep harsh weather outside where it belongs. However, this is not an easy job, so you should expect some wear and tear over time. Basic maintenance can help your products last longer. Clean your windows and doors after a storm to ensure nothing is stuck in the joints or hardware. You should also check your windows for cracks, as even small ones can seriously affect performance. Check the weatherstripping as well and replace it if necessary.
