Insulating fixtures: characteristics, tax deductions and concessions, degree of insulation and all the info on insulated windows.

Theinsulating fixturesallow you to protect your home fromthermal dispersionsso as to save on costs in the bill.

The efficiency and degree ofinsulationof afixtureit is evaluated based on the value ofthermal transmittanceof the materials that compose it (generally, frame and glass).

The value ofthermal transmittanceè is the most important data for determining whether afixtureit is wellinsulating. The lower this value is, the higher the insulating performance will be.

Thermal transmittance is expressed inW / m2K, i.e. watts per square meter per degree Kelvin. In the energy label ofinsulating fixtures, the thermal transmittance is indicated with the letter U and affects the average heat flow per square meter of surface that passes through the frame. Specifically, the thermal transmittance of ainsulating frameis given by the mean betweenthermal transmittance of the frame(Uf) and the thermal transmittance of the glazed part (Ug), a contribution is added to this value which translates into the total transmittance value Uw.

Insulating fixtures and tax breaks

The replacement of the fixtures is one of the works ofbuilding renovationwho are entitled totax deductions50%. If, with the adoption ofinsulating fixtures, the house increases its degree ofenergy efficiency, the tax breaks increase with an IRPEF deduction of 65%.

To access thetax breaksin the context ofreplacement of windows, you need to install insulating fixtureswhich guarantee the thermal transmittance values ​​required by law, these values ​​vary according to the climatic zones to which they belong.

Insulating fixtures: glass

The window market offers a wide range of types of windows. In residential properties, windows and doors withdouble glazing with versions worked out according to circumstances.

Theredouble glazingit is given by several layers of sheets of a transparent material. These sheets may differ from each other based on the thickness, profiles, sealant and type of air chamber. The sheets are sealed with a specific glue and spaced apart by means of profiles that form the thickness necessary for setting up the dry air chamber. To increase the degree ofinsulationof thewindow frame, the air chamber can be saturated with gases other than air. Generally, they are used to fill the cavity and increase the thermal insulation of the framenoble and inert gasessuch as argon or krypton which due to its characteristics would seem the most efficient and with the lowest value ofthermal transmittance (very insulating).

On the product sheet, in addition to the total thermal transmittance (Uw, which is the average between the thermal transmittance of the frame and the sheets), the various thicknesses of the different components are indicated. The thickness measurements are indicated in the following order: external glass, cavity, internal glass. The gaseous element that saturates the interspace is also specified.

There is no shortage of plates and special glass. In this context, the following are configured:

  • low-emissivity coatings
  • reflective glass or solar control glass
  • selective glasses
  • glasses capable of absorbing heat
  • diffuser glass or colored glass
  • photochromic glasses
  • wired glass
  • solar control glass
  • safety glass

Low-emissivity or low-emissivity glasses reduce heat losses because they incorporate a layer of metal or a metal oxide which further decreases the thermal transmittance of the glass. The basis of any special glass is given by a common glass plate.

To increase the degree of insulation of theinsulating fixturesyou go to act on various factors: you can increase the thickness of the various layers that make up the glass ceramic window, you can increase the number of glasses used and thus also the number of cavities, you can use different gases to fill the chambers of air (also to increase the degree of soundproofing), carry out precautions on the profiles and frames ...
