Features of glass greenhouses

To get an early harvest of healthy and tasty vegetables and herbs, summer residents build hotbeds and greenhouses on their backyard plots. The modern market for garden tools offers similar structures of various shapes, sizes and designs.

Glass structures have remained the most demanded greenhouses for many years. They are not only not inferior to greenhouses made of film and polycarbonate, but also surpass them in many respects. A glass greenhouse is a reliable assistant that will protect the crop from early frosts, diseases and pests and increase the quantity and quality of vegetable crops.

Glass greenhouses are durable and reliable structures that let the sun's rays pass well and retain heat, which allows you to extend the summer season and makes it possible to harvest two crops.

They have a number of undeniable advantages:

• the possibility of using both new material and used material for the construction;
• the possibility of self-production and installation of the product;
• environmental Safety;
• unlimited service life;
• resistance to temperature fluctuations and negative environmental influences;
• ease of care;
• neat appearance;

• the possibility of using designer toning for a specific color shade;
• high light transmission and transparency;
• maximum use of daylight;
• resistance to corrosion, decay and deformation under the influence of sunlight;
• stability of thermal expansion indicators;
• affordable price when manufacturing from old windows and doors;
• the possibility of partial replacement of damaged elements;
• preservation of its properties throughout the entire period of operation;
• resistance to acids, pesticides and chemical compounds.

Disadvantages:

• the fragility and massiveness of the glass structure require a reliable foundation and frame;
• rapid heating of the air requires constant ventilation;
• possible damage from strong wind, hail and mechanical stress;
• the use of tempered glass will significantly increase the cost of the structure;
• high cost of material when replacing it;
• absorption of ultraviolet radiation.

At the moment, there are several types of the most popular designs of glass greenhouses on frames:

• made of steel pipes, qualitative examples - products of the Udacha and AGS trademarks, have a long service life, a high percentage of light penetration;
• from galvanized profiled pipes - aesthetic appearance and high quality of products;
• from wooden frames - an economical and budgetary design option;
• from metal corners - they require experience in joining parts by welding;
• their metal profile - glasses are inserted into the grooves of the metal frame and fixed with adhesives and sealants.

Using special programs with three-dimensional models or making a simple drawing on a sheet of paper is an individual choice for each builder.

For competent drawing up of drawings, you must follow some rules:

• determine the size of the required glass and its quantity;
• choose the type of foundation and the material required for the purchase;
• choose a frame of the required size;
• calculate the surface area of ​​the glazing;
• determine the length, width and height of the structure;
• determine places for ventilation and installation of transoms and vents.

Particular attention should be paid to timber-framed structures.

The installation process consists of several stages:

• construction of the lower harness;
• mounting of vertical racks;
• construction of the upper harness;
• roof and glass installation.

Professional builders with experience in working with metal and welding machine, it is advised to choose a structure from metal corners and carry out the work in a certain sequence:

• fix the corners in the horizontal direction with anchor bolts on the foundation;
• make support and vertical posts;
• weld the lower strapping;
• weld the top harness;
• connect the rafters and the ridge of the roof;
• weld the top harness and rafters with a ridge together;
• carry out the glazing.

There are several forms of glass greenhouses, with varying degrees of complexity during installation and their own characteristics:

• classic - a popular option with a gable roof for effective snow cover;
• with a pitched roof - a simple and inexpensive option, it is used as an extension from the south side to a fence or building;
• Mitlider's greenhouse - a modernized version of the classic greenhouse, has a raised slope with built-in transoms for high-quality and efficient ventilation;
• a thermos greenhouse is an expensive and time-consuming option, ideal for winter greenhouses, the structure is located below the surface level and has a brick or concrete wall;
• dome - a complex frame structure with the use of non-standard glass, an ideal option for the location of lighting, has a high degree of resistance to winds;
• pyramidal - creates an optimal temperature regime for plants.

Experienced builders and summer residents are advised to follow some rules when installing a structure:

• glass must be used with a thickness of at least 4 mm;
• when choosing a material for glazing, it is imperative to take into account the type of frame;
• for winter greenhouses, it is recommended to use a high-quality heating system and artificial lighting;
• when self-manufacturing greenhouses from old windows and doors, it is necessary to carefully check the reliability of fixing the material to the frame;
• to protect the metal frame from corrosion and moisture, it is necessary to treat all its elements with special solutions;
• for the installation of a winter greenhouse, it is necessary to use double-glazed windows with one or two chambers;
• exact determination of dimensions and construction of construction drawings is mandatory;
• for areas with a lot of snow cover, the slope angle must be increased.

Before starting work on the installation of a glass greenhouse, it is necessary to pay attention to the choice of a place in the country for the installation of the structure.

The site must meet several criteria:

• no shadow - uniform illumination of the entire area throughout the day, the best option is the south side;
• flat surface - the territory should be flat, without depressions and bumps;
• absence of winds and drafts - preferably location between buildings and in places with constant movement of air masses;
• accessibility to water and electricity supply points - proximity to communications will significantly reduce the costs of water supply and connection to power grids.

A glass greenhouse with heavy cladding and a volumetric frame must be installed on a monolithic strip foundation made of concrete mortar and a brick base with strict adherence to technological standards:

• prepare the construction site - remove debris, bushes and trees;
• mark the place of the foundation with a rope and pegs;
• dig a trench of the prescribed size;
• to compact the bottom and walls of the trench;
• pour gravel, slag or sand at least 10 cm thick;
• install the formwork and fill it with prepared concrete mortar;
• lay the reinforcement rods for strength and pour out the remaining solution;
• cover with plastic wrap and stand for 5 days, complete solidification will occur in a month.

The arrangement of the basement is advised by professional builders to be carried out in compliance with the following sequence of work:

• laying on a pre-prepared mortar using a building level and a stretched rope;
• remove excess solution until it solidifies;
• install anchor bolts in the designated places for the subsequent fastening of the frame;
• lay a layer of waterproofing material.

The most important stage of installation, requiring experience and professional knowledge and advice, is glazing.

It is carried out in several stages:

• fastening to the inner side of the frame of the rails;
• cutting a glass sheet of the required size;
• installing glass in the right place, smeared with adhesive or silicone sealant;
• fixation from the outside with a prepared rail.

The modern world of design solutions opens up new aspects of the use of conventional glass greenhouses. The classical use of the structure for growing vegetables and fruits fades into the background, although it remains a very popular and necessary process. Decorators and graphic designers have filled the greenhouses with flower arrangements and created unique places to relax in them at any time of the year.

Unique ideas are given to us by nature itself and the world around us.

The light, transparent and almost invisible design of the glass greenhouse with beautiful flower arrangements will become the highlight of the suburban area.

A greenhouse made in the form of a garden with a resting place for all family members will become a favorite pastime even in inclement weather.

A brick foundation and a dark wooden frame will give the structure an appearance of reliability and high cost. Such a greenhouse will become a real decoration of the personal plot.

The airy structure on a rough metal frame will extend the summer period and warm with its warmth on cold autumn days.

The modern world and the ecological state of the environment bring new rules to people's lives. Buying fresh vegetables and herbs in winter and early spring is expensive, and the presence of harmful nitrates makes them life-threatening. A greenhouse on a garden plot makes it possible not only to get the necessary harvest for the whole family, but also to decorate the territory, make it a cozy place for relaxation and creative inspiration at any time of the year.
