Because Bouwplast doors are also used primarily in agricultural and industrial construction we know exactly what is important. No fussy decoration but sound quality for an attractive price. This is why the doors always have strong steel reinforcing profile strips, a sturdy 3-point closing system and standard multi-chamber draught-free profile strips. They are fitted with insulating, break-in resistant double glazing or insulating plastic sandwich filling sheet. As you can see Bouwplast plastic doors are just as good as more expensive makes.
