Thermal insulation in the house is an important stage of arrangement. The insulation material can be mounted on various clips, which include Rondol washers. This connector has gained great popularity due to its reliability and quality, as well as its easy installation.
Methods of fixing insulation to the surface
You can fix the insulation on the wall in one of three main ways:
- Create a crate. It is a frame base, in the cells of which the material is laid. As rails, metal galvanized profiles are used that are not susceptible to corrosion and temperature.
- Glue base. This is a method that requires compliance with a number of nuances. Firstly, it is necessary to choose the right composition so that it meets all the requirements and is compatible with the insulation and surface. Secondly, it must be resistant to moisture. Only adhesive fixation is rarely used, usually the method is combined with dowels.
- Dowels and screws. This is the main method of fixation, which provides reliable fastening to the wall. Rondol washers belong to the same category.
Each method has its own nuances and features that must be considered before starting work. The optimal method is chosen according to the state of the wall surface, the type of insulating material and environmental factors (temperature, humidity).
Item Description
The Rondol washer is a clamp which is made of high-quality polyethylene. Reliable material allows the element to hold the insulation layer on the surface without displacement. The washer is a removable part, so if it becomes unusable, it can be replaced.
An external distinguishing feature of the device is the squeezed logo of the manufacturer OMAX. The washer is resistant to sudden changes in temperature, so it can be used in adverse weather and climatic conditions. Polymers are used as the material of manufacture. It is made in the form of a ring into which a screw is inserted.
Main characteristics:
- Standard packaging contains 50, 100 or 200 washers.
- Diameter - 50 and 60 mm.
- The material is polypropylene.
- Suitable for fastening to walls made of wood, chipboard, OSB, thin sheet steel.
- It should be used in conjunction with reliable stainless steel screws of various sizes. They are selected based on the climatic conditions in which the insulation is attached, as well as the thickness of the insulation.
Fasteners provide a tight pressing of the material to the wall. It has a high level of resistance to adverse factors (moisture, temperature).
Mounting requirements
The fastener is subjected to high mechanical stress during operation. For this reason, a quality retainer must meet the following requirements:
- Resistance to destruction. The washer and the self-tapping screw to be mounted must have high strength. It is better to take nails from galvanized steel.
- The fastener material must have low thermal conductivity. Otherwise, it can become a "bridge of cold."
- Provide high adhesion. It should create adhesion to any surfaces and insulation.
These are the basic requirements that must be followed for any fastener.
Surface mount
Installing the washer to the surface is simple and convenient. Any home master can perform installation without using a professional tool.
Installation Algorithm:
- Surface preparation. It must be cleaned from debris and old plaster, as well as holes and bumps.
- Marking the places where the clips will be attached.
- Adhesive insulation on a special composition.
- Creating holes in the wall for a screw. The hole depth should equal the length of the screw with a small margin. Also, the calculation takes into account the thickness of the attached insulator.
- Installation of a washer Rondol for fastening a heater. A screw is screwed inside until the material is finally fixed.
- Joint Processing.
- Installation of waterproofing and vapor barrier.
- Finishing the wall.
For maximum efficiency, you should combine the Rondol washer with hardened screws with a diameter of 5 mm and a length of 5-10 cm. You can install using self-tapping screws.
Washer for insulation Rondol is used for tight and reliable mechanical pressing of the insulation to the surface. Suitable for fixing soft and hard heat-insulating materials: polystyrene foam, mineral wool and others. Can be fixed on surfaces made of wood, concrete, plastic, metal, brick.
Advantages and disadvantages
Positive qualities include:
- Low price.
- Simplicity and ease of installation. No special equipment is required.
- Wide range of operating temperatures. A washer for thermal insulation is used inside buildings and outside.
- Practicality. When attaching mineral wool, foam and other insulation to the washers, reliable fixation can be obtained. In this case, the thermal insulation will not change its original shape.
- Operation under the influence of ultraviolet radiation is possible.
- Not subject to corrosion.
In the case of strong pulling the washer, the Rondol for fixing the insulation may burst. Because of this, the installation must be carried out carefully, without excessive pressure on the product.
For reliable mounting, it is necessary to calculate in advance how many Rondol washers are required. The number of products depends on such parameters as surface height, sheet location, insulation area, material width, structure features and its density. For ordinary sites, 5 fasteners are enough. Corner mounted on 6 clips. Buildings with a height of 8 to 20 meters require 7 fasteners per 1 sq.m. Surfaces over 20 meters are mounted on 9 washers.
