EC Marking

• What is EC Marking?

EC is a European conformity mark based on the manufacturer's declaration that the product conforms to Community requirements.

Windows and external pedestrian doors are covered by the European Construction Products Directive 89/109/EEC, amended by Directive 93/68/EEC, which regulates the placing and free movement of construction products in the European Economic Area and defines the minimum parameters expected when they are placed in the construction site. The community directives are of mandatory transposition for the European Union countries and in Portugal the directive was transposed into national legislation by Decree-Law No. 113/93 of 13th April and republished by Decree-Law No. 4/2007 of 8th January. Identification of products and materials: Standard NP EN 14351-1:2008 considers three types of products:

- Windows (sill or balcony);

- Exterior pedestrian doors;

- Roof windows.

•  What are the changes for the market?

All products must be identified with the EC Mark (either on the object or on a separate document).

It works like a passport that allows the free circulation of products within the European market.

• What does this imply for Navarra?

Navarra - Extrusão de Alumínio, S.A., as the creator of aluminium architectural systems, is responsible for defining the types to be tested, in accordance with the product range and scope of application.

The systems developed are subject to initial type tests at Notified Bodies in accordance with the EN 14351-1 and EN 13830 product standards, for windows and pedestrian doors and façades.

Technical information and test reports are made available to locksmiths/manufacturers, Navarra's partners, so that they can manufacture products that reflect the obtained results.

• How to preserve and correctly maintain your windows?

In order for the surface of the frames to remain in good condition, we recommend:

Installation on site or painting the walls

The fitting of the frames on site should be carried out after the civil works are concluded. It can still be carried out on site, but it is necessary that the frames are properly protected to avoid contact with other materials which may damage the aluminium.

Cleaning

1. The frames, including rubber seals and brushes, should be cleaned with water and a 5% solution of neutral detergent, using a sponge or soft cloth.

2. Windows and sliding doors require the bottom rails to be constantly cleaned to prevent dust accumulation.

3. Do not use detergent formulas containing ammonia, scouring pads or any other type of abrasive material.

4. Do not use acid or alkaline products as they may stain the aluminium.

5. Do not use sharp or perforating objects to help clean the premises. It can be done with the help of a soft-bristled brush soaked in the solution indicated in 1.

6. Do not use products derived from petroleum (e.g. Vaseline).

• What types of window openings do you know of?

Windows may be sliding, fixed, casement, turn and tilt windows, among others. The most functional option should be chosen according to the intended use and aesthetics, knowing that, in terms of energy and as a general rule, casement (opening) windows perform better in comparison to sliding windows, since the latter have greater air permeability. However, for a better insulation, regardless of the type of openings for your home, always choose windows with Thermal Break.

• What is an aluminium system with Thermal Bridge Break (TBB)?

It is a more efficient aluminium frame.

An efficient window uses the Thermal Bridge Break in its system. But what is this?

They are products made with profiles that incorporate insulating elements, thus reducing the thermal exchanges between the interior and exterior environments.

The correct selection of the aluminium frame (or profile) can guarantee high performance solutions for the window. It is important to have insulating materials in the profiles (thermal bridge break) so that they have even better thermal performance, reducing the need to use mechanisms for cooling and/or heating the spaces, thus originating energy and environmental savings.

 

Aluminium

• Did you know that aluminium is a sustainable material?

Aluminium is one of the most abundant materials in the earth's crust, with practically unlimited availability in raw materials. Aluminium comes from bauxite, one of the most abundant elements on our planet, and is therefore 100% sustainable.

Aluminium's material properties contribute to its low environmental impact, making it a green product for the environment.

It is also 100% recyclable, endless times, and maintains its properties unchanged.

Its lightness, strength/weight ratio, hardness, aesthetic component, malleability, high resistance to corrosion and external agents have made aluminium one of the most widely used materials in the world.

Another aluminium feature is its durability and strength, which makes it a perfect material for both your windows and for the most diverse uses in products for industrial use.
