Construction sequence: Install roof purlins, install thermal insulation gaskets, lay Jiakun heat insulation reflective foil (steam insulation and heat insulation), lay insulation cotton, lay Jiakun waterproof and breathable membrane - fixed bracket - install the upper layer
Install the color steel plate (aluminum plate) on the lower layer Color steel plate (aluminum plate)
Installation of roof purlins
Purlins are installed in accordance with relevant specifications and design requirements, and thermal insulation gaskets are installed above the purlins.
Laying heat insulation reflective foil (vapor barrier and heat insulation)
Description: Jiakun heat insulation reflective foil, also known as aluminum foil composite heat insulation and waterproof cushion, heat insulation and waterproof integrated membrane, has excellent vapor barrier Thermal insulation and waterproof functions.
, Jiakun heat insulation reflective foil faces upward and is laid on the purlins along the vertical direction of the roof purlins.
. Paste a section of butyl tape (each section is 3mm long) at intervals of 3mm on the roof purlins to temporarily fix the heat-insulating reflective foil.
The thermal insulation reflective foil should leave enough sag between the two roof purlins to ensure that it is filled with insulation cotton.
. There is an overlap between two pieces of heat-insulating reflective foil. It is recommended to use sealing tape for water and air sealing at the overlap.
Lay thermal insulation cotton
Lay thermal insulation cotton between two roof purlins and on top of the insulating reflective foil along the direction of the purlins
Lay Jiakun waterproof and breathable membrane (vapor-permeable waterproof cushion)< br/> Jiakun waterproof and breathable membrane (vapor-permeable waterproof cushion) is laid face up on the insulation cotton and heat insulation reflective foil along the vertical direction of the roof purlin.
. Paste a section of butyl tape (each section is 3mm long) at intervals of 3mm on the roof purlins and on the heat-insulating reflective foil to temporarily fix the waterproof and breathable membrane.
For the overlap between two waterproof and breathable membranes, it is recommended to use sealing tape for water and air sealing at the overlap.
Fixing the Bracket
Use two pieces of butyl tape (each length is mm) to stick on the waterproof and breathable membrane where the bracket needs to be fixed. Place the bracket on top of the butyl tape and fix the screws to the butyl tape. Tape on.
Install the upper color steel plate (aluminum plate)
The upper color steel plate or aluminum plate is installed on the bracket. The specific installation method is according to the design requirements.
Install the lower color steel plate (aluminum plate)
The lower color steel plate or aluminum plate is fixed under the roof purlins. The specific installation method is according to the design requirements.
How to deal with roof exhaust pipes and brackets
, How to deal with roof exhaust pipes:
). At the roof exhaust pipe, cut the waterproof and breathable membrane into a piece slightly smaller than the exhaust pipe. The outer diameter of the round hole.
), use half of the width of butyl tape to stick it around the bottom of the waterproof and breathable membrane along the opening, and the other half of the tape around the outer wall of the exhaust pipe and stick it to the outer wall of the exhaust pipe.
), wrap a circle of sealing tape around the outer surface of the connection between the waterproof and breathable membrane and the exhaust pipe as a closing treatment.
. How to deal with roof brackets:
Use butyl tape to tightly paste a circle of waterproof and breathable membrane openings at the connection between the bracket and the purlin, then put it into the bracket, stick it with the tape and squeeze it tightly, and use sealing on the outer surface of the connection.
Wrap a circle of tape as a closing treatment.
