How to close the ends of polycarbonate

For a polycarbonate roof to be durable and weather resistant, the ends must be closed correctly during installation. Because of their strength and low weight, polycarbonate sheets are frequently used for roofing; however, if the ends are left open, they can collect dust, let water in, and have a shorter lifespan.

Using end caps or polycarbonate profiles that have been specially made is one efficient way to seal the ends of polycarbonate sheets. The purpose of these accessories is to create a tight seal that keeps weather and debris out while fitting snugly over the edges of the sheets.

Start by taking an exact measurement of the width of your polycarbonate sheets. This measurement guarantees a perfect fit for the end closure profiles or caps. To precisely match the width of each sheet, the profiles or caps must be cut to the appropriate length.

After preparing the profiles or caps, give the polycarbonate sheets’ edges a thorough cleaning. Eliminating any particles of dust or debris guarantees a spotless surface for attachment and improves the seal’s efficiency. Make sure the sheets are completely dry before moving on, and use a gentle cloth and a mild detergent if needed.

Sealant for polycarbonate: how to seal joints

Polycarbonate sheets are easily drillable, bendable, and cut during assembly. But it’s important to keep in mind that the ends must be sealed. When installing structures, this is one of the most crucial operations. After meeting all installation requirements, the structure will function for over a decade. How should joints be sealed using polycarbonate sealants?

Application

Polycarbonate is widely used in national and agricultural construction projects. Numerous qualities make this material dependable, including stability, durability, environmental friendliness, etc.

As seen in the picture, carbonate panels in particular were frequently used to create greenhouses. They are excellent at scattering and missing light, which benefits green areas. Moreover, heat retention in these greenhouses can reach up to 35%.

You need to consider sealing the ends of polycarbonate structures that you erect. You can use a specific tape made for this material to accomplish this. Use two varieties of these tapes at the moment:

These add-ons are made expressly to shield mobile carbonate from debris and water infiltration. A self-adhesive tape has an infinite lifespan. It can tolerate variations in temperature and is sensitive to shifts in carbonate sheets. Additionally, in the cellular polycarbonate cavity, adhesive tape maintains a relative microclimate. Additionally, when assembling the design, the tape can tolerate the friction caused by the edging.

The product withstands extremes in temperature and humidity with unwavering resolve. The polycarbonate adhesive tape’s surface is coated in a unique material that keeps out different types of fungi. It has a potential service life of over ten years. Although the tape’s adhesive layer is very dependable, it can be repacked if needed thanks to a feature.

Hermilent (continuous)

Hermilent is used to keep precipitation from reaching the upper portion of the carbonate sheet connection. As seen in the picture, if the panel is positioned vertically and the honeycombs are likewise upright, the upper end of the panels must be fully sealed with tape for polycarbonate. The continuous tape is made to prevent different kinds of wet precipitation (hail, rain, and snow) from penetrating the cell carbonate floor.

Perfolet

As seen in the picture, this accessory is used to shield the licarbonate compound from below. The air filter built into the perforated tape has pores that are 40 microns in size. They are the ones who forbid other litter from entering the first half of the material. Furthermore, the filter has the ability to transfer moisture outward, which builds up in carbonate honeycombs. This adhesive tape is designed to protect the lower joint of the panel in the event that it is installed vertically and the honeycombs have a direction.

The ribbons have various functions depending on the kind of structure. At the junction of the connection, two inclined panels are covered with perfolet below and closed with hermolent from above. Only a perfume is performed when the arched structures made of cellular carbonate are being constructed at both ends. In addition, as seen in the picture, tiny holes must be drilled at the end with a step of 25 to 35 centimeters to ensure that the condensate does not remain.

If the moisture cannot escape the honeycombs, which is where it always goes, the material will soon start to degrade. In this scenario, the cost of repairing the structure will be high. Additionally, avoid using regular tape since it cannot shield the material from harm.

Sealing different materials at the points of connection can be done in a variety of ways. Among these is silicone sealant, which, as the image illustrates, is used to seal polycarbonate goods.

Silicone sealants are used to keep the carbonate panels in place and to seal the joints between them. As seen in the picture, they are utilized, for instance, in the assembly of greenhouses made of polycarbonate sheets.

Sealants offer the following benefits:

• Elasticity. The material at temperature drops is able to compensate for any shifts of the joints to which it is applied;
• Transfer any temperature during prolonged operation;
• Excellent sticking to polycarbonate;
• Is not exposed to various atmospheric influences, as well as mechanical damage.

We will summarize

Finally, it should be mentioned that specific sealants must be used when working with polycarbonate. In this instance, the design won’t break or require additional expenses for a very long time.

In our "Everything about the roof" guide, we examine workable solutions for properly sealing polycarbonate panel ends. This important step prolongs the life of the material and improves the durability of your roof by preventing moisture buildup. We cover all the information you need to guarantee a safe and weatherproof finish for your polycarbonate roofing project, from easy do-it-yourself fixes to expert methods."

Instructions for the installation of cellular polycarbonate

Cutting cellular polycarbonate sheets and polycarbonate profiles is fairly simple. Emphasize the use of high-speed circular saws for optimal cutting results. Such saw blades should be reinforced with solid alloys and have small, uniform teeth. To prevent vibration when cutting polycarbonate panels, the profiles need to be consistently maintained. Using a strip saw, you can also cut.

Chips must be removed from the panels’ internal cavities after they have been cut.

Sealing the cellular polycarbonate panel’s ends

Significant Adjust the panel ends appropriately. The upper ends of sheets that are positioned vertically or inclined must be sealed with a continuous aluminum self-adhesive tape. To ensure condensate drainage and stop dust from penetrating, close the lower ends with a special perforated ribbon. Perforated tape needs to be used to seal both ends of a design that resembles an arch.

It is highly recommended to use end polycarbonate profiles that are similar in color. They are highly practical, dependable, and aesthetically pleasing. These profiles’ design fixes the ends of the panels fairly densely and eliminates the need for additional fasteners.

Drilling multiple holes in the end profile is necessary to guarantee the condensate drain.

It’s not allowed. The lower ends of the panels should be hermetically sealed, and the ends of the cellular polycarbonate should be left open and secured with regular tape.

The orientation of polycarbonate panels during design and installation

Internal stiffness ribs in cellular polycarbonate are positioned along the sheet’s length (usually 3 m, 6 m, or 12 m). The panel needs to be positioned so that any condensation that forms inside of it can escape through internal channels and be seen outside of it.

Stiffness ribs should be positioned vertically in the pitched structure along the slope if the glazing is oriented vertically. Should the frame appear curved, the stiffness ribs ought to follow the curve instead of running parallel to the floor. These conditions need to be considered even during the design phase when figuring out how many cellular polycarbonate sheets to use and how to cut them correctly.

Cellular polycarbonate with a unique protective UV stabilizing layer applied to the panel’s exterior is recommended for usage on public roads. A polycarbonate sheet has a protective film with a unique marking on this side. It is advised that you install the panels without taking off this film, but you should wait to do so until the job is finished.

It is not permitted to bend the panels along a smaller radius than what the manufacturer specifies for a particular polycarbonate thickness and structure. You cannot also go against the guidelines for sheet orientation.

Panels with point mounting

Using unique thermo-shayb and self-tapping screws, the sheets of cellular polycarbonate are point mounted to the frame.

Heathba It is made up of a sealing washer, a snapping cover, and a plastic washer with a leg whose height matches the panel’s thickness. With the aid of this tool, polycarbonate panels can be fixed securely and dependably, and the "cold bridges" produced by self-tapping screws can be removed. Furthermore, the leg of the WHOLE will undermine the structure and stop the material from being crushed.

The holes in the panels need to be made 2-3 mm larger than the diameter of the thermos leg in order to account for the thermal expansion of the cellular polycarbonate. Additionally, it is advised that the holes be made longer along the sheet if the panel is long. A step mounting step of 300–400 mm is advised.

Cellular polycarbonate panels are prohibited. Retighten excessively, unscrewing self-tapping screws, and using the wrong washers, rivets, and nails to secure items.

Panel connection and fastening

Unusual, detachable polycarbonate profiles—which can also be transparent and colored—are used to join sheets of cellular polycarbonate.

Installation with an endless supply of profiles.

The panels are placed into the profile grooves that match the cellular polycarbonate sheet thickness. Then, this profile is fixed to the frame’s longitudinal supports using self-tapping screws fitted with thermo-hawks.

Additionally, panels can be installed with detachable polycarbonate profiles. They are made up of two parts: a snapping lid on top and a lower part called the "base."

1. Holes are drilled in the “base”, the diameter of which should be slightly larger than the diameter of the screw. Step about 300 mm.
2. Attach the “base” using self-tapping screws to the longitudinal support of the frame, and then lay the sheets of polycarbonate on both sides, leaving the “thermal gap” about 3-5 mm.
3. With the help of wooden kiyanka, snap the “lid” of the profile along the entire length. Then close the ends of the profile with special plugs.

What considerations must be made while creating the cellular polycarbonate structure

When building a coating out of cellular polycarbonate, it’s crucial to consider:

• standard sizes of material sheets and their economical cutting;
• exposure to snow and wind loads;
• the thermal expansion of polycarbonate panels, for example, with a seasonal temperature change from -40 to +40 ° C, each meter of a sheet of cellular polycarbonate will undergo a change in about 5.2mm;
• when creating arched structures, permissible radii bending of panels;
• The need to equip cellular polycarbonate with mounting elements (self -tapping screws, thermal -shirts, connecting and end profiles, self -adhesive tapes).

Comprehensive instructions on how to open, fasten, and use the required and suggested installation tools for polycarbonate.

When thinking about how to finish the ends of polycarbonate sheets for a roofing project, it’s critical to make sure the finish is weatherproof and secure. Using unique polycarbonate closure strips that are made to fit snugly over the sheet edges is one of the most popular techniques. These strips help to seal the ends against moisture and dirt in addition to giving them a tidy appearance.

Make sure the closure strips you install fit the profile of your polycarbonate sheets. An appropriate fit and strong sealing are guaranteed by this compatibility. These strips are usually composed of long-lasting materials like polycarbonate or PVC, which provides longevity and UV resistance—both of which are essential for outdoor applications.

The secret to maximizing the effectiveness of closure strips is proper installation. Make sure the right screws or clips are used to firmly secure the strips along the edges of the polycarbonate sheets. This keeps the integrity of your roofing structure intact over time by preventing any gaps that might let water or debris in.

For even more protection, think about applying silicone sealant along the edges. To improve the waterproofing even more and achieve a seamless finish, add a bead of sealant where the closure strip meets the polycarbonate sheet. By taking this step, you can greatly improve your roofing system’s resistance to weather.

You can ensure longevity, weather resistance, and a clean look for your roofing project by effectively closing the ends of polycarbonate sheets with these steps. Whether you’re building a new roof or renovating an old one, focusing on these details will help you come up with a durable and dependable roofing solution.
