Choosing the right MODEK product
MODEK manufactures a wide range of rooflighting systems that are suitable for any type of building, be it a home, a warehouse, a commercial building or a sporting facility.
• MODEK manufactures glass-reinforced polyester (GRP) and polycarbonate in a range of masses.
• As a rule, the heavier the sheeting, the longer its lifespan and the more adverse the weather conditions it will be able to withstand.
• MODEK is able to advise clients on which mass should be selected for a given application.
