Building a Greenhouse - What Materials Are Best and Why

Building your first greenhouse should be cheap and easy to construct. If you have never built a shed like structure before, you will gain a lot of experience building just a simple greenhouse and can then move onto more advanced plans.

There are a variety of different materials that you can use to build your greenhouse. Here are the three most popular and what their advantages and disadvantages are.

PVC Easy, Cheap But Limited

Working with polyethylene or PVC is very easy and you will not need to have a lot of diy experience in order to construct a greenhouse with this material. It is inexpensive to purchase and is lightweight to work this. The most obvious disadvantage of this material is that it does not always have the best durability and may not stack up well against heavy and drastic weather conditions. Even if relatively calm weather conditions, it may be a challenge to meet all the requirements unique to your weather.

Lumber Durable, Cheap But Requires Planning

Working with wood is easy. The cost may be a little more than PVC, but there are the added advantages that the structure will be able to handle far more extreme weather conditions. If you plan to build a greenhouse out of wood, you will want to think about ventilation, access points and lighting. Having a selection of plans to work from will produce the best results.

Glass Durable, Effective and Expensive

Glass Greenhouses tend to be very difficult and expensive to construct. They are highly effective in that they allow for plants to experience natural lighting while taking advantage of a protected, warmed environment. Cutting and dealing with glass can is not an ideal first greenhouse project and planning is vital when working with such fragile materials.

What Building Materials Are Considered Sustainable?

We are all aware that our natural resources are depleting. This is why it is only right that we learn about the sustainable materials. Such materials are great option for building new homes or other buildings. There is a need to be more conscious of where we get our materials because if not, our planet will be completely destroyed. But before we pick a material, we have to see to it that it is truly sustainable. Learn about the different factors to check before you can claim that the material is indeed sustainable.

Why use sustainable materials?

Before understanding what these materials are, it is essential that we understand why we need to start using them. The need to start using these materials roots from the state of our environment and natural resources. Bear in mind that wood is still one of the most preferred materials in building establishments. And where do woods come from, trees. Trees take years to grow and will only take moments to cut, if this practice continues, we will lose all the trees in our forests resulting to further damage in our planet. The use of these materials will reduce the waste and energy consumption when building structures.

What are sustainable materials?

You have to satisfy many criteria before you can call a material sustainable. First, you have to check the energy used in order to have that material. The acquisition of that material involves a lot of processes like harvesting, processing and finally, transporting them. All these processes consume energy that emits carbon monoxide to the environment.

Before you can call them sustainable, you have to check where they are from. Are there plenty of them left? Are they reproducing and growing rapidly? In addition to that, these materials should be eco-friendly and should not have substances that can be harmful to the environment. Moreover, you should be able to recycle them. As much as possible, their scraps should be used to produce other things or will be used to produce other materials. Locally produced materials are preferred because they do not have to be transported. Thus, no energy is wasted for that purpose.

A good example of sustainable material is the engineered lumber. This is from the fast growing smaller trees. This means that the harvested lumbers are easily replenished. Other substances and derivatives are combined with the lumber to produce a material ideal for building.

Using sustainable materials has many benefits.

Although building a home using the said materials is more expensive, it is worth it. It is more costly because the resources are managed. The forests where the trees are from are maintained to ensure that new trees will grow to replace those that were harvested. Such materials benefit everyone. The owners are able to live in a toxic-free, energy-efficient home. Moreover, the materials used are replaced, which others can use in the future.

Since they are sustainable, no harm is done to the environment while you build your dream home. This is good because Mother Nature do not need more damaging activities.

Sustainable materials are important because it provides the need of users to have reliable materials without harming the environment.

Salvage Building Materials

One of the most recent innovations in the construction industry is the development of the "Green building," which is the process of building structures that use environment-friendly building materials and building methods. Among the criterion that a building must meet to be considered "green" is that the house should be built using environment-friendly building materials. This is because building materials play a major role in making a structure environment-friendly. As seen in the past, using building materials such as asbestos or those that release toxins can have a detrimental effect, not only to the builders and future occupants, but to the environment as well. However, environment-friendly materials are not only limited to those that do not release toxins or pollution -- recycled materials are also considered to be environment-friendly.

One very good example of recycled or salvaged building material is steel. This is because steel is 66 percent recyclable, and can be derived from scrap metal, including old automobiles, machines and old steel buildings. This means that using steel does not require e mining because it can be derived from recycled metals. In addition, precious resources such as trees are also preserved if steel is used to build structures instead of wood. Apart from being good for the environment, using steel also has other advantages. Steel is stronger and able to withstand extreme weather conditions, and it is cheaper than most building materials. It is also fire resistant, resistant to termites, rotting and cracks.

More and more people are becoming aware of environmental issues and new environment-friendly innovations are being developed. The development of alternative building materials used to build structures like homes is an example.
