PVC Casing : features , types , installation

PVC casings are plastic strips of the profile, which are often used to frame the window openings of private homes, as well as doors.The casings are used primarily to hide the significant disadvantages that must exist between the wall and the window (door).These plastic elements also allow to get rid of drafts.

In addition, often the owners set trimsonly to decorate the structure.With their help, even the most unremarkable housing becomes outwardly pleasant.Fortunately, the market can find a lot of casings, which correspond to the appearance of most modern buildings.Also do not forget that such products often are made to order, so you can always buy exactly what you need, given the size of the material, as well as its appearance and properties.

In this article we consider in detail the main advantages of PVC casings, as well as their main characteristics.Also, examine the installation of casings in the ordinary residential buildings.

main features of PVC casings

As already mentioned, PVC frames successfully conceal the gap present between the window and door openings.In this case, we have an excellent opportunity to hide the significant shortcomings of the structure, which may have been committed even during construction.Moreover, often used PVC trim to hide the seams are not the most smooth foam.The aforementioned gap has successfully filled this sealant, after which enough to cover the consequences of repairs data.Most often, PVC trims have internal voids to easily hide even the most serious mistakes made by the builders or owners of the house.

In addition, the void that exists between the wall and the window is often used for the installation of a small amount of insulation material.This is especially effective if all the walls are already covered with insulation.However, it is quite suitable and conventional polyurethane foam, which is also characterized by a good performance.

A esteem PVC casings the following:

• attractive appearance.As mentioned in the beginning frames can have a variety of variations.Accordingly, owners easier to choose the option that meets their expectations, as well as the external structure of mind.Very often, manufacturers offer by the buyers to use my own.For example, it may be the original patterns, or abstraction.Often, however, PVC trims are under the wood.Accordingly, it is a neutral option that perfectly blends with virtually all dwellings.
• cheapness.Since the frames are made of PVC, the material is incredibly cheap.Earlier frames made of wood, and the cost was very high.At the same time the wood over time lose their initial properties, as well as an attractive appearance, which is not true of products made of PVC.In this regard, plastic trims can be freely set in all the appropriate places, not paying attention to the financial component repairs.
• durability.Plastic hard enough to hurt, but it can be done if a strong desire.At the same time ordinary weather events will never be the cause of damage to the PVC casings.In the event of any problems the material can be easily replaced, so it is best to buy a few casings reserve.
• easy care material.Unlike wood, which is necessary to cover the protective compounds and cleaned regularly, the plastic product can be operated over many years, and the appearance of casings not change.However, sometimes the surface casings should still remove dust or dirt.

There have PVC casings and disadvantage.It is a material that has low moisture resistance.Accordingly, if they go constant rains, the frames may be slightly change its appearance is not the best way.But often trim on the doors and windows are located under the peak of the roof, so the essential reasons for concern.

Species casings

Now on sale you can find two types of casings.Each of them will be discussed separately.

• Plastic trim sheet type.This is a good option to use in repair work, as this material has two useful variation - a flat casing and voids.Such products are not subject to deformation at sharp change of temperature.Moreover, the material does not absorb moisture, therefore always remains in perfect condition.
• Polyvinyl chloride or polyurethane frames (PVC).This is precisely the products we are talking about in this article.By and large, the previous material and have almost the same properties, but PVC frames can have the original topography.Moreover, they are often used in the inner space and housing.

Recently becoming more common becomes the second option.Probably all for the very reason that the PVC frames are embossed surfaces.It is said that the original texture of the material on the surface like a conventional timber.

Also, when buying casings should pay attention to their mountings.Recently manufacturers produce casings with snaps.However, they may have some drawbacks associated with the deformation.Accordingly, such products may not be able to securely attach.Accordingly, the purchase is necessary to pay attention to each unit of goods, so as not to get into trouble.And on the anchorages PVC casings to be recognized primarily because of this aspect may depend much until fully tightened.

specifics of installing PVC casings

First of all, we must understand that you need only acquire trim after having been bought by the window (or door if the setting casings going on around them).The fact that the plastic product must comply appearance windows.For example, if the windows have a black frame, it is necessary to select the appropriate version of the casing.

As for the installation of PVC casings, then there are several options:

• On the basis of the mounting members.This is a standard fasteners, which are very often used in the majority of construction activities.It should be borne in mind that it is the most reliable and durable option as fasteners, such as dowels and screws, used by builders for decades, so any problems can not arise at all.Regarding the choice of fasteners, the better in this regard refer to the consultants who give good advice.Also, the recommendations can give directly to produce casings.
• Based on the original clips.This structure is mounted directly on the basis of the window frame.Thus, we get a holistic design that looks great, but also features a good quality.Many owners are wary of various pushpins, as they can be damaged quite easily.However, this is not quite true.Modern manufacturers pay much attention to quality.The problem, however, is of concern to many is the fact that the frames can be relatively easy to remove.These and enjoy some of the attackers.
• Based on the double-sided tape.This option is rarely used, and even in that case, if the casing is flat and has a very modest weight.Surprisingly, the double-sided tape copes with its immediate task, but occasionally the tape will still have to change.Also, an adhesive tape may fail in that case, if the street a strong wind.

Accordingly, if we analyze all of these options, the first seems the most appropriate.It should also be said that often during the construction of frames and windows are supplied from one manufacturer, so in this case ignore the latch will not work.In that case, if they fail, you can personally carry out the installation on the basis of the mounting members.

It was the first version of casings installation we will talk in more detail.

Installation casings based fasteners

This process consists of several steps:

• To start happening measurements of the window frame, this procedure is carried out with the top point and the bottom.Once this measurement is required to add the width of the casings.It should be borne in mind that these elements are often installed around the perimeter and, at the level of the top point.Selecting casings mounting depends solely on the owners preferences.Although, of course, the installation of casings on the perimeter of the frame - it's like the best in terms of thermal insulation of buildings (more on that later).
• Further there is cut the necessary components of the panels.It should also be borne in mind here that the measurements should be carried out particularly accurately, since even small flaws can affect the final result.As already mentioned, it is better to take a few extra casings, as in the construction process happen a variety of problems that are difficult to predict.The material is often cheap, so no problems should not be.
• Now it's time to make cuts at an angle of 45 degrees.This procedure is performed with each trim or on both sides.Most often used for such manipulations special mounting angles that already have all the necessary markings.It is worth paying attention to the fact that stykovanie between elements should take place without any problems, so if there is at least the slightest hitch should again check the created angle.
• After that, the layout of the wall where the installation will take place casings.There is also need accuracy, since then drill holes using the punch.The diameter of the drill should correspond approximately to the diameter of the future fasteners.It will be only two holes for each casing.Immediately after drilling started in the hole hammered dowels.They can be nylon or plastic - it does not matter.
• Next trims are applied to the surface, then there is their fixation with screws.It should be borne in mind that the fasteners must firmly push the plastic material, but do not overdo it, because the casings are brittle.

Installing insulation under architraves

many interests trim only for the reason that for them can make installation of insulation.As already mentioned, it is actually a good opportunity to improve comfort in the home.However, it should be noted in advance that the result of this work will be felt only in the event that all housing is already insulated.

To carry out this process around the window opening there must be a gap.It should be borne in mind that this is the gap can have different dimensions, and it is necessary to pay attention to.Visually, the available space should be enough to install the insulation.If the gap is too small, should be limited to only installing the casings.

As for the installation of thermal insulation, in this case suitable mineral wool.add up to mount it so that the material looked like a double layer.After the need to try to hold the material in the gap.It will not be easy, but it is possible.The excess part of the insulation can be cut, but she insulation should protrude slightly from the wall.It is necessary to make sure that there are no gaps between the wall and the insulation is not.Next comes the installation of casings, which are located close to the insulation.

instead of mineral wool, as already mentioned, you can use assembly foam, which is also good shows itself as insulation.
