PVC windows

PVC windows are among the most popular solutions for renovation projects. Their generally affordable cost, combined with good thermal insulation performance, makes them a popular choice for many homes.

PVC is also easy to maintain and available in various colors, although white remains the most common finish. Manufacturers also offer custom-made models to fit the dimensions of each opening.

However, this material is less suitable for very large windows. Some municipalities, condominiums, or housing developments also impose restrictions on its use. It is therefore recommended to consult local planning regulations before replacing your windows and doors.

Aluminum windows

Aluminium windows are appealing due to their strength and excellent weather resistance. They are particularly suitable for regions exposed to humidity, heavy rain or harsh climatic conditions.

Aluminum also offers slim profiles that maximize natural light. However, being a conductive material, its thermal performance can be reduced if the window or door frame doesn't incorporate a suitable thermal break. Before starting any work, it's advisable to request a quote to assess the installation cost.

Wooden windows

Wood remains a go - to material for renovating older homes or projects seeking an authentic look. It offers a warm aesthetic and can be easily customized with paint or other available finishes.

Its main drawback lies in its maintenance. Exposed to humidity or high temperatures, the wood can crack or deteriorate over time if it is not regularly protected.

Pergolas: what materials for a sustainable outdoor design?

The choice of material is just as important for a pergola , since it determines its resistance to climatic conditions, its maintenance and its lifespan.

The aluminum pergola

Aluminum is one of the most widely used materials for pergolas today, especially bioclimatic models. It is weather-resistant, does not warp or crack, and retains its appearance over the years.

Available in many sizes, shapes and finishes, it also allows for custom projects while requiring very little maintenance.

The vinyl pergola

Vinyl is an economical , low-maintenance alternative. However, it can soften or warp under the effect of strong temperature variations, which limits its appeal in some regions.

Another limitation is that vinyl pergolas are often sold as standardized kits offering limited customization options. Before making a purchase, it's advisable to request a quote to compare available solutions.

The choice of material depends primarily on the project constraints, the local climate, the desired performance, and the available budget. For windows , PVC, aluminum, and wood meet different needs in terms of insulation, aesthetics, and maintenance. For a pergola , aluminum appears to be a particularly durable solution, while vinyl can be a more economical option depending on the conditions of use.
