Vello pultruded profiles for window and door frames provide producers efficiency and long lasting quality. A particular area of expertise for us involves intricate profiles with numerous details.

High dimensional stability

The coefficient of expansion of glass fibre reinforced polyester profiles is very low and almost identical to that of float glass. Expansion and contraction with changing temperatures is minimal and the profiles retain their stiffness at high temperatures.

Low thermal conductivity

The thermal conductivity of the material is very low and GRP insulates better ...
