How to Waterproof Solar Water Heaters on Steel Structure Roofs.

Construction procedures for roof waterproofing of lightweight steel structures. Construction procedures. Construction procedures. Construction Procedures:

1. Check and clean the base surface of the painting area and try to remove the old original waterproof coating material.

2. First apply a layer of MetaSeal Multifunctional Waterproof Coating. When wet, insert the pre-cut waterproof polyester fabric into it and smooth it with a brush to ensure there are no bubbles or bubbles. tasks. If there are wrinkles, apply MetaSeal Multifunctional Waterproof Coating from above, completely saturating the waterproof polyester fabric until completely dry.

3. Check all painted parts and repair them in time if there are any; any defect.

4. Apply 1-2 coats of MetaSeal heat-insulating reflective paint that resists UV agingon the painted surface.

5. Clean up the construction site and related objects, and then inform the relevant responsible person for inspection and acceptance.

6 The construction area of ​​the light steel structure roof should be maintained for 24 hours . 3-5 days, which is conducive to achieving the most ideal state.

Should solar water heater be booked in advance for self-built houses?

It is better not to install solar power on tiles in colored steel, because solar energy is too heavy. after water is supplied, the bearing capacity of color steel tiles is relatively low and can easily collapse. Second, even if it is not crushed, it is not easy to repair. When strong winds hit, solar energy can be easily knocked down.

Colored steel tiles, also known as colored profile tiles, are pprofiled lacquers made of colored steel plates that are cold rolled and bent into various corrugated shapes. They are suitable for industrial and civil applications. buildings, warehouses, roofs, walls and interior and exterior wall decorations of special buildings and large-span metal structure houses have the characteristics of light weight, high strength, rich colors, convenient and quick construction, strength earthquake protection, fire protection, rain protection. , long life and maintenance-free, etc., and are now widely promoted and applied.

Mandatory

1.

The solar water heater must be placed on the roof above the south-facing shower room.

2. If the roof is flat, it can be installed directly without leaving a foundation on the roof.

3.

If the roof is sloping, it depends on whether it is a no sloperd-south or an east-west slope. For example, if the angle between the north and south slopes is not large, a steel structure platform frame 200mm higher than the ridge surface can be made. The frame columns are connected and fixed to the steel structure in the ridge.

For east-west slopes, the reserved solar foundation platform should be rotated 90 degrees, that is- i.e. the width of the solar collector is on the south side

4. Under or on both sides of the rooftop solar water heater Reserve a box of at least DN80 in the room

so that the solar connection pipe can enter the room.

Solar photothermal conversion materials are the most important solar materials. Materials in the field of photothermal use can be divided into thermal storage materials, thermal conductive materials, thermoelectric materials, heat collecting materials, etc.
