Wood, vinyl and aluminum windows, can result in problems with warping, rotting, cracking, bowing and shrinking. Fiberglass with its lack of brittleness and deterioration of surface finish has the highest resistance to warping & twisting. Frame & sash corners will not separate or crack. Fiberglass can be subjected to harsh weather conditions and stand the test of time. Throughout any climatic environment, fiberglass stays rigid and stable without loss of physical property see other fiberglass applications

     
 

Besides physical issues, Fiberglass has outstanding Thermal Performance: See chart below for "U" and "R" Values

Finishes: All exposed surfaces are painted with a 1.5 mil semi-gloss coat of two-part acrylic/urethane enamel. This paint will not chip, scale, blister or discolor under most severe weather conditions.

Fiberglass comes in a variety of Standard Colors:
Sandalwood
White
Commercial Brown
Ivory
Green

Fiberglass unlike Aluminum and Vinyl can be painted with a urethane base paint.

 
   
 
Other Benefits of Fiberglass:
Ease of Installation:
Windows remain square, level & plumb during the installation process.
Energy Efficiency:
A 20-40% savings in heating/cooling/energy costs over other window frame materials.
Condensation:
Reduction in moisture & condensation, therefor less likely to produce mold.
904L stainless steel is replica watches uk a super heat-resistant stainless steel alloy. Is replica watches currently only used in high-tech fields, such as the aerospace, chemical and rolex replica petrochemical industries, but also for surgical transplants. It is very resistant to corrosion, which is rolex replica uk comparable to many precious metal materials because of its high content of chrome content of 21%.
Sound Transmission:
With tight seals, there is a high resistance to sound transmission, reducing exterior noise to a minimum.
Operation:
Resistant to bowing, therefore continuously smooth operation.
Insulation:
Fiberglass is a natural insulator because it is does not conduct heat and cold and it doesn't expand or contract.
