What to choose aluminum or PVC-windows

PVC Window

   ABOUT

   Polyvinyl chloride has a low coefficient of thermal conductivity, which means that better retain heat in the room, as this depends on the profile (the area of ​​the profile is on average about 15-20% of that of the entire window - that is, not with crucial for total heating effect).

   AGAINST

   PVC ages more rapidly than the aluminum (20-30 years) because it is of organic origin. For the same reason it is more susceptible to the vagaries of climate and temperature support structure of the material breaks down and the profile is distorted.

   ABOUT

   PVC joinery is manufactured and installed more easily because of the nature of the material itself, which of course is softer and flexible than aluminum.

   AGAINST

   As a result of long exposure to the sun inferior (ie cheapest) windows yellow.

   ABOUT

   PVC joinery requires minimal maintenance - does not need painting, treatment with special preparations, but simply by washing with a soft cloth and soap.

   AGAINST

   The PVC profile has a large linear expansion - 2-3 mm per meter (depending on the origin and even more).

   ABOUT

· The production of PVC profiles requires less investment, which ultimately lowers the cost of the woodwork.

· PVC condense moisture harder than aluminum. Anyway humidity in the room more than 60% moisture condenses hard on profile and easy on the glass, cold walls and corners.

· PVC allows locking systems with multipoint closing price. This type of hardware, except burglary effect allows more precise adjustment of the hinges and prevent the effect of "my spirit of the woodwork."

         Corners of PVC glued which prevents blowing through them, but ... on the other hand makes it impossible for the introduction of large funds (for gateways, for example) in most rooms.

 

Aluminum (aluminum windows)

 ABOUT

Aluminium is immune to the large temperature differences in our latitudes - from extremely hot (almost African) summer to minus 20 degrees in winter (60 degrees Celsius amplitude). That is, the structure of the aluminum is not changed with the passage of time.

 AGAINST

Aluminium is an energy-intensive product and thus more expensive than PVC.

 ABOUT

Aluminum does not change their appearance over the years. It does not require any maintenance other than simple cleaning.

 AGAINST

Aluminum is colder material and more easily condense moisture.

 ABOUT

The strength of this material allows complex solutions such as curtain and structural facades, roofing, winter gardens.

 AGAINST

Faulty aluminum windows (you will know its low price), placed in an environment with high salinity (near the sea, for example), gives an unpleasant effect - a surface layer bubbles appear.

 ABOUT

· Slightly more expensive version of the aluminum frame - with thermal break - approaching its thermal insulation characteristics to those of PVC. "Thermo" aluminum allows placement of multi-closing mechanisms, with the possibility to fine tune the opening parts.

· If you get tired of aluminum windows, you can sell 30% of the new profile, which is unthinkable in PVC.

· COLORS! With aluminum windows have virtually unlimited choice of colors. Besides the RAL (standardized worldwide classification of colors with over 800 colors) to choose between the so-called effects SABLE, POLYDROX, METALLIC and others.

· Standard profile with thermal break allows placement of 12 types of glass holders for 6 types of glass, PVC profiles while limiting the thickness of the glass to 2-3 types.

Aluminum does not contain toxic elements fire and earthquake-resistant
