Basement Window

A basement window is a smart addition to any basement area. Not only does it allow in more natural light, but it also ensures proper ventilation. This creates healthier and more pleasant air quality in the basement. Basements are often known for being dark and damp, but by installing a well-placed basement window, you reduce the risk of mould growth and musty odours. Opt for a well insulated basement window, and you’ll also prevent draughts and heat loss, helping you save on energy bills.

In this guide, we’ll explain the materials you can use for your basement window, how to install one, and why plastic is the ideal choice for this task. Of course, we’ll share some tips and answer the most frequently asked questions, too.

  • Customisable to your exact size
  • High-quality, durable materials
  • Perfect for light and insulation

What is a basement window?

A basement window is specially designed for use in basements and serves multiple purposes. It can provide ventilation, let daylight in, and sometimes even act as an emergency exit. Positioned at or just above ground level, it’s a practical solution to brighten up what might otherwise be a dark and enclosed space.

There are various types of basement windows available: fixed models, tilt and turn systems, and ones with a hopper mechanism. Many basement windows are made from plastic, and for good reason; plastic is strong, insulating, easy to clean and has a long lifespan.

Why is a plastic basement window ideal?

Using plastic for a basement window offers numerous benefits when compared to traditional materials like glass or wood. Plastic is stronger than glass while being lighter and easier to work with. It’s nearly maintenance-free and highly resistant to moisture, which makes it perfect for basements prone to dampness.

While glass is fragile, offers lower insulating capability, and can pose safety risks if broken, plastic alternatives like acrylic and polycarbonate are impact resistant and much safer to use.

Wood is another option, but it falls behind plastic due to its higher maintenance needs and low durability in damp conditions. When it comes to sustainability and low-maintenance convenience, plastic, particularly acrylic or polycarbonate, easily comes out on top.

Our recommendation

Polycarbonate is our top choice if your basement window needs to handle a bit of wear and tear. It’s ideal for places where safety and impact resistance are essential, like a basement that may be prone to break-ins. On the other hand, if your budget is the main priority and you’re mainly looking for maximum light, acrylic is an excellent option. Both materials are suitable for indoor and outdoor use, making them perfect for basement windows.

Installation

Installing a basement window isn’t overly complicated, but it does require precision. This ensures proper insulation without draughts or leaks. Follow our step-by-step guide for successful installation and make sure your window fits perfectly.
