Transparent roof from plexiglass: a dubious decision or undeservedly forgotten material?

Envision a house where an all-plexiglass roof lets in an abundance of sunlight, softly illuminating every nook and cranny of the space. Both architects and homeowners are intrigued by the concept of a transparent roof, particularly when materials such as plexiglass are used. Is it a wise decision or a forgotten treasure from the past?

Plexiglass is a strong and lightweight substitute for glass that has various benefits. Because of its transparency, natural light can enter indoor spaces, making them feel light and airy without sacrificing structural integrity. A plexiglass roof can improve the indoor-outdoor connection for areas like sunrooms and covered patios by offering protection while allowing users to still enjoy the sky above.

However, there are factors to take into account before choosing a plexiglass roof. Though it might appear like a creative decision, there are useful considerations to make. Compared to conventional roofing materials, Plexiglass is more prone to scratches, and maintaining its clarity over time may call for specific cleaning methods. Furthermore, its insulating qualities might not be as good as those of more traditional roofing materials, which could have an effect on energy efficiency.

In the past, plexiglass roofs were a common feature in mid-century commercial architecture, as well as in some modern-looking residential buildings. But as time went on, other roofing materials became more well-known for their strength and thermal efficiency, and they began to lose popularity. Notwithstanding this downturn, plexiglass’s distinctive features call for a reevaluation in modern design.

What is a plexiglass

Transparent polymeric material made from acrylic acid is called Plexiglass. Which is why acrylic glass is its second name. Additionally, plexiglass is occasionally referred to as Plexiglas because this polymer was initially manufactured under the Plexiglas brand in the years following its development.

The advantages and disadvantages

When he invented it in the 1930s, Ottoshess was a true innovation. Particularly in aviation, even though practically everyone quickly started to benefit from it, from furniture to glasses. constructed plexiglass roofs, mostly for greenhouses and greenhouses.

Acrylic glass has generally become a very common material. And not just like that; those are only its primary benefits:

• shock viscosity is 5 times more than that of ordinary silicate glass;
• translucency up to 92%, which is comparable to the indicators of special enlightened glasses;
• does not cloth over time;
• stability to ultraviolet – no protective coatings are needed;
• low thermal conductivity, which reduces heat loss through transparent structures;
• small weight-about 2.5-3 times lighter than glass;
• thermoplasticity – already at a temperature of 120 ° C, a plexiglass is softened;
• preservation of optical properties when changing the form;
• Chemical resistance: acrylic glass resistant to alcohols, mineral oils, fats, alkalis, unconditioned acids;
• biologically resistant;
• Simplicity of processing: millennium is easily cut, welded, glued;
• frost resistance -withstands up to -40 ° C;
• Environmentally friendly material – easily processed, during burning it does not emit toxic substances.

Any translucent structures made from plexiglass with such qualities were a successful solution for the roof. Even more than successful, considering that silicate glass was more expensive in the 1930s than acrylic glass. And the price difference was entirely multiple after ten to fifteen years.

However, this was short-lived as alternatives soon emerged. And all as a result of the structured glass’s flaws:

1. Relatively fragile. Although it is 5 times more silicate, more silicate, it can still be broken by a strong blow. For example, if an icicle falls on the roof of the terrace on the roof of the terrace.
2. Easy to scratch. Yes, the plexiglass almost does not degrade over time under the influence of sunlight, but it can still become cloudy due to many scratches on the surface.
3. Low softening temperature. This is the advantage for forming products, and a disadvantage, if we are talking about enclosing structures. For example, the roof of a plexiglass rests on the frame, as a rule, a metal one, which on a hot summer on a sunny day may well heat up to +80 ° C or more.
4. Combustibility. The most critical disadvantage of the ex -glass is its fire temperature, which is only 260 ° C. At the same time, the material burns perfectly after the source of fire is removed.

The material’s "black label" was established by the flammability of acrylic glass. Due to these characteristics, plexiglass was abandoned in many industries, including the aircraft industry, as soon as polycarbonate and other more resilient polymeric materials appeared as an alternative.

Types of plexiglass

There are two kinds of organizers for the roof:

• cast (casting), in which the melt of the polymer is poured into a special shape;
• extrusion (crushed, acrylic glass under pressure) – material obtained by squeezing molten mass through shafts or extrusion head.

Despite the fact that these two kinds of organes share most of the same characteristics, their production processes result in notable distinctions.

Casting

For a transparent roof, cast or glass is thought to be a better material than extrusion. This is because of how it is made; unlike extrusion, cast acrylic glass is just heated and doesn’t require any additional pressure. He benefits from the following attributes as a result:

• high impact resistance due to higher molecular mass;
• uniform shrinkage after solidification;
• large possible thickness of the sheet;
• above the temperature of softening (the difference with an extrusion plexiglass 10-20 ° C);
• higher chemical resistance;
• great predictability in thermoforming.

Among the flaws, the largest inaccuracy in thickness and the lowest possible length of the cast glass are noteworthy.

The orgpeslas generally follows the same guideline as the other structural polymeric materials: alternative techniques are preferable for obtaining cast plates.

Extrusion

Compared to cast, extrusion organs are less dense. This establishes its fundamental characteristics:

• less impact resistance;
• below resistance to chemical influences;
• the best ability to glue the material;
• below the softening temperature;
• above the shrinkage.

Moreover, extrusion glass has much greater size limitations than cast glass. Actually, the workshop’s size is the only restriction on its length. Additionally, because extrusion errors are significantly lower than casting errors, the thickness is more stable.

Exstrus plates should not be used as plexiglass for roofing. However, they are ideal for the production of multicomponent furniture and interior decoration.

An interesting idea for contemporary architecture is a transparent plexiglass roof, which combines style and practicality. Although it is frequently overlooked in favor of other materials, plexiglass has special advantages like strength, adaptability, and natural light diffusion. However, a number of variables, including climate, upkeep requirements, and long-term cost-effectiveness, affect its viability. In an effort to provide light on the benefits and drawbacks of plexiglass roofing for both potential builders and renovators, this piece investigates whether this material is a daring yet sensible choice in modern architecture or if its potential has been unjustly underutilized.

Is it worth making a roof out of an plexiglass?

The specific location in which you plan to use acrylic glass will determine the answer to this query.

This is a good solution if the milleten extends from the main house to the roofs of the terraces or gazebo. In this instance, there is no chance that an icicle will break through the roof, and if it does catch fire, it is unlikely to spread to the residential structure. However, the benefits of exagges—most notably its translucency and resistance to deterioration over time—will become evident.

However, even in this instance, the terrace’s roof still needs to be precisely made of plexiglass. It is not advised to add all glass to it, for instance, to create a closed gazebo. Such a design will ignite nearly instantly in the event of a fire, preventing people from entering and allowing them to escape swiftly and painlessly.

This is most definitely not worth it if you plan to install plexiglass on the veranda’s roof or use it to create a transparent atrium roof. Interior décor is always intended to spread flames, so if the acrylic glass catches fire, a residential building could easily catch fire as well, regardless of whether it is constructed of brick, gas block, or another non-combustible material.

You are misinformed if you believe that a high fence or tight adherence to fire safety regulations will shield you from this. When the humidity is high, Orgshydlo can ignite with ease from any spark, even a tiny spit of the wiring. Travelers still use acrylic glass as kindling because it burns so well. Thus, there is no need to take a chance because orgster roofs have no place close to residential areas.

Choosing between a plexiglass transparent roof is a choice that frequently causes discussion among architects and homeowners alike. One of the special benefits of using plexiglass, a strong and lightweight material, is its resistance to weather and impact. Because of its transparency, natural light can flood interior spaces, making them feel light and airy.

But even with these advantages, there are important things to keep in mind. Even though it’s strong, Plexiglass scratches easily and needs to be cleaned frequently to keep its clarity. If exposed to sunlight for an extended period of time, it may eventually turn yellow or break easily, which could shorten its life and make it less attractive.

In addition, the expenses associated with installing and maintaining a plexiglass roof may be greater than those of more conventional roofing materials like metal or shingles. It is necessary to consider the advantages of natural light and its modern design aesthetics when evaluating this financial investment.

Plexiglass roofs are still appropriate in modern architecture and design, despite these drawbacks. They provide a sleek, contemporary appearance that goes well with industrial and minimalist designs. Plexiglass roofs can be an appealing option for modern homes or commercial spaces looking to maximize natural light and create an air of openness.

In conclusion, even though plexiglass may not be the best material for a transparent roof in every architectural context or price range, people who value modern aesthetics and maximizing natural light intake should give it some thought due to its special qualities. When deciding if this material is the best choice for your roofing needs, it is important to carefully weigh the lifespan and maintenance costs.
