When building a new home, the installation of your PVC apertures is just as important as the quality of the apertures themselves. At Finestral, we recommend installing your windows and doors during the shell stage of construction, rather than waiting until the finishing stages. This innovative approach offers several long-term benefits that improve your home’s comfort, appearance and protection.

Once the contractor has prepared the window sills, the apertures can already be installed. Each frame is sealed to the surrounding brickwork using high-quality expansion foam, creating an effective barrier against air infiltration while significantly improving both thermal and acoustic insulation.

To further enhance energy efficiency, the internal and external window sills are installed as two separate pieces, creating a thermal break that reduces heat transfer between the inside and outside of your home. The result is a more comfortable living environment and lower energy consumption throughout the year.

This installation method also delivers a cleaner, more refined finish. Once the final plaster finish is applied, the aperture blends seamlessly into the surrounding wall, eliminating the need for exposed acrylic joints that can deteriorate over time and require ongoing maintenance. By increasing the thickness of the facade insulation and plastering around the aperture, it is also possible to achieve the minimalist frame appearance that has become increasingly popular in contemporary architecture.

Another important advantage is that your property is sealed much earlier during construction. This provides increased security while helping protect the interior from rain, wind and water infiltration as the remaining works continue.

The Benefits at a Glance

• Superior thermal insulation for improved energy efficiency.
• Enhanced acoustic insulation for a quieter home.
• A cleaner, seamless finish with reduced maintenance.
• A minimalist external appearance with less visible framing.
• Earlier protection from weather and improved site security during construction.
