Knowing how to choose a door to thermal insulation is very important, and because the property is protected from the action of the adverse weather conditions and because the heat stays within the four walls. This will also help to cut heating costs and give a hand to the environment, reducing energy waste .

The doors that provide a thermal insulation are usually made ​​with a steel thicker and more resistant than the traditional one. When you are preparing to choose a frame of this kind, make sure that its share is not less than 24-25 gauge. Verify that there are at least two layers of steel, and among them there is the insulation material. Many companies offer a totally ecological variant, consisting of polystyrene CHFC, which in addition to energy savings, effectively resists dents and warping. The frame should present a good zinc coating, which will protect the door from the corrosive rust.

The insulation must be of the last generation and have within them the layers of tubes, able to perfectly insulate the house from the elements. Ensure the compliance of the door insulation, viewing the documentation attached, which must bear the material used, specifications, warranties of energy upgrading and certification of compliance to the laws in force (the port must be marked with the universal EC). Coatings best to retain the heat inside the house are, the more modern PVC, the versatile aluminum and the classic wood. This variety allows you to enter the frame that best suits your style of decor, combining technology, design, innovation and solidity.

If you live in a particularly cold area and you need an extremely safe, you prefer a door in galvanized aluminum or PVC, completely impervious to frost and various weather . The wood is suitable for homes that already have a great system of heating , because it has a heat-insulating capacity slightly lower than the previous materials . If you opt for this solution, be careful to choose doors constructed in the form lamellar and implemented by a layer of aluminum will be more resilient and will last longer over time .
