Technical description of Inverted Flat Roof Insulation
Surface cleaning
Cleaning of the surface with special machines and local surface repairs (wherever required).
Creation of slopes
Laying Τherbobeto® heat-insulating lightweight concrete to create 2% slopes. If required, two coats are made. After the laying with Terbobeto®, the surface is smooth with the use of scraper.
Primer adhesion
Application of asphalt varnish with high adhesion
First waterproofing
Coating of the first THERMODIEN NERO membrane 4kg -10οC which is perpendicular to the slopes coated widthwise 15cm & along 15cm between the rolls, while the joints widthwise do not coincide.
Second waterproofing
Then follows the hot gluing of the second bitumen membrane THERMODIEN ENERGY PLUS SBS (ΕΝ 13707) with a non-woven polyester weight carrier 6Kg per m2, -20οC & weight of polyester cloth180gr/m2 .The bonding of the membranes is perpendicular to the slopes with a width of 10cm & 15cm between the rolls, the widthwise joints do not coincide.
Installation of thermal insulation
Installation of the XPS extruded polystyrene thermal insulation plates & grouting the joints of the plates with the same material (if applicable). The thickness of the thermal insulating material needed is assessed by our certified insulators and is arranged upon consultation with the owner.
Special system pieces
Special membrane pieces are installed to further strengthen the system seal. The special pieces are placed on the perimeter parapets.
Coating with gravel
Coating with gravel. The weight of the gravel protects the thermal-insulating plates from buckling. The gravel can be replaced with other material upon consultation with the owner.
Ventilation system
Installation of special type ventilators from which water vapor is discharged at about 30-60 m2 & at the highest points of insulation.
Mechanical fastening of the membrane
Mechanically fastening of the membrane with special blade pieces and sealing with polyurethane mastic.
Protection of compounds.
Cold coating on all the bituminous membrane compounds by applying ROOF ENERGY COOL elastomeric, highly elastic and waterproofing material based on new technology of acrylic & polyurethane resins.
Gutter protection
Reinforcement in the gutter nozzles with special membrane placement and ROOF ENERGY COOL coating as well as polyurethane mastic. At the end of the work, protective grills are placed in all the gutters so that they do not block from tree leaves and other objects.
We use only certified insulating materials and our own certified & specialized insulation crews.
