Aluminum offers usually state the Company and the series (e.g., casement frame Europa 5000). Many individuals believe that by stating these two characteristics, they can compare two aluminum offers. Unfortunately, this is not enough to evaluate and compare two offers. A balcony door or window (e.g., Europa 5000, Alumil 9400) can be constructed in many ways that affect its performance, appearance, functionality, and price. It is characteristic that a casement frame accepts three types of gaskets (foam rubbers, claw, bubbles, see terminology), many types of mechanisms (simple or perimeter), and many brands (Roto, GU, Giesse). Also, it can be constructed with simple or bevelled glazing beads that change its appearance, with bolts or a second sash handle (on the sash without a handle). All these affect its use. Furthermore, offers and frame prices do not state whether they include tilt-and-turn functions, door handles, type of sliding guides, etc.
The safest way to ascertain all this is to visit the frame manufacturer and ask to see exactly the type and frame that will be installed for you, because many construction details (sliding guide end caps, perimeter thermal break gaskets, screens with cover caps) are not visible in the offers.
If, however, you are unable to do this, it is advisable to ask the following questions regarding the aluminum offers you received:
- Does the price include installation, dismantling, and removal of old frames?
- Are tilt-and-turn functions and handles included in the doors?
- What gaskets are included in the frames (foam, claw, bubbles)?
- Which company’s mechanisms (Roto, Giesse) and what type (simple, perimeter)?
- What type of glazing beads?
- What type of shutters and screens does the manufacturer use and where do they source them from?
- What type of profiles, from the series you selected, will be used for the construction of your frames to avoid fixed sashes?
- What type of energy-efficient glazing has been offered?
Frame replacement is a beneficial investment, but it is done once and will stay with you forever. Therefore, dedicate a little more time to choosing your partner and evaluating aluminum offers.
