Give a beautiful finish to your exterior siding with the G-Teck starter moulding! G-Teck's lightweight and recyclable vinyl components are waterproof, unaltered by water, and can therefore withstand heavy washing and bad weather. They have superior fire resistance, as they are very hard to ignite and absorb flames. These components require little maintenance, since dirt does not cling to pores and can usually be wiped off with a simple cloth. Quick and easy installation. White wood-like finish.
