The Characteristics of SPI Windows

Thermal insulation

SPI windows and doors ensure a high savings energy, thanks to their very high performance of thermal insulation certified.

Window frames play an important role in determining the internal temperature of a house and can be determining in a energy refurbishment of a building. For this reason, SPI has studied frames that provide high thermal insulation. The PVC windows are, by their nature, highly insulating and have excellent performance in energy efficiency. The aluminum windows, however, to achieve this result, are equipped with the so-called "thermal cut", ie the insertion of insulating material (polyamide) between the inner and outer profile of the window, accompanied by a low-emissivity glass. This combination ensures protection from the cold of winter and the heat of summer.

The windows SPI, also, can be equipped with special aluminum shutters or other shading systems that always ensure the best temperature.

All SPI windows, both new PVC and aluminum windows, have the energy parameters to enjoy the 50% tax deductions provided by the State in case of replacement of old windows.

Acoustic Insulation

Every SPI window and doorframe is designed to meet a specific housing requirement, made up of energy saving, resistance over time, but also, and not least, of sound insulation. In fact, thanks to the solidity of the materials and the absolute precision of the profilatura, SPI windows and doors guarantee the exclusion of any external noise that may bother the customer and disturb the peace and relaxation in the home. For those who live in busy areas or near railway stations, acoustic glazing is the ideal solution: it is laminated glass consisting of two panes joined by one or more plastic films with high acoustic attenuation, a kind of shock absorber that blocks acoustic vibrations.  


The company's passion for quality and design, in line with the needs of a market that is constantly evolving in its aesthetic criteria, means that significant investments are constantly being made in research and development.

The customer can choose from a various range of colors and finishes, for a design that suits every living environment.

For those who love a sober and welcoming style of decor, SPI offers, in addition to solutions in aluminum, also aluminum-wood windows, such as the line Trial Q, with aluminum frame and solid wood interior profile customizable, available in different colors.

Certification and Durability

Every window and doorframe produced by SPI is the work of many people who work with care and dedication on a daily basis, using materials that are not harmful to people or the environment and making production decisions that are geared towards eco-sustainability and the safeguarding of the environment. SPI pays particular attention to material disposal and recycling policies. All SPI windows and doors carry performance certificates, issued by the most accredited certifying bodies, as required by Italian law. Samples of products are subjected to stringent "in-house" tests to check their tightness with regard to water infiltration, air permeability and wind resistance. This is done to ensure that the performance of the windows produced consistently matches the certification classes obtained at external testing institutes, thus guaranteeing the CE mark.
