Polyurethane system and protection layer
The advantage of using the Polyurethane system and the protection layer
(water and thermal insulation system together) :
• The ability to be executed on all the surface types ( metal – wood – concrete)
• Light weight , the weight of the substance at density of 45kg/m2 and the thickness 4cm2 kg/ m2
• The lease substances which link the heat 20 watt/ m2 kelvin m2.
• Complete resistant to the water , salty water and the alive creatures .
• Is not affected by the bugs , fungi , and does not cause smells and against corrosion .
• Very high resistance to changing weather , winds, rain and can get rid of the tiles and the reclamation above.
• No existence of any cords on the roof because it consists of interdependent and gathered layres with each other because of the cumulative spreading .
• The fast execution to execute at two levels only which can be one of the fastest water and thermal insulation systems for the surfaces to execute and cost and the least to prevent other articles .
The way of executing the Polyurethane on the surfaces :
Conditions before start :
- Clean the surface , cutting steel rods .
- Light weight foam concrete or plaster layer .
- Action cant strip 7*7 cm around plaster of the roof .
- Action threshold for the roof door ..
The water and thermal insulation systems for the roof
|4||Water proofing membrane
|Polyflame||Derma bit||Py 40E250
|6||Protection for the thermal insulation|
|10||Modern rain filter (two florrs and airing )|
Alzamil Company recommends choosing the first solution .
Method of application :
- Apply guide lines after 3 days from works start order .
- Apply light weight concrete (cement / water / electricity ) by client /
- Starting the foam concrete by water for 3 days .
- Apply cant strip around the roof.
- Apply primer for the cant strip.
- Apply waterproofing by overlap 10 cm lingth and 15 cm width.
Condition after waterproofing :
- Plumping villas start after the completion of the waterproofing fluid test for 2 days maximum .
- The client is fully responsible for the safety of the waterproofing layer from the hole and scratches and exposure the sun for along time.
- Protect the waterproofing layers.
Clarifying system for the thermal and water insulation for the surfaces :
- Reinforced concrete.
- Foam concrete (sliding) .
- Cant strip .
- Primer basic layer .
- Insulation first layer bitumen rolls .
- Insulation second layer bitumen rolls .
- Thermal insulation .
- Protect for thermal insula.tion .
- Slated membrane .
- Aluminum flashing .
- Sealant paste .
