Why should you prefer marmoroc façade over synthetic plaster for heat insulation?

A façade heat-insulated with Marmoroc is more expensive as an initial investment, but much cheaper in the long run. The oldest house covered with Marmoroc is already over 50 years old and thrives without regular maintenance. The life expectancy of synthetic plaster is approx. 25 years if an annual inspection is performed and the façade is repainted every 5 to 7 years.

Today, heating prices are so high that if the façade and heating system are renovated, financial savings will be greater than a bank loan. Our experience shows that with a complex solution, 40% reduced heating costs are realistically achievable.

Marmoroc is the most durable façade - meaning less maintenance for you over the next 30 years.

When insulating façades, apartment associations have to choose not just to insulate a wall but also to understand what the house’s appearance will be for many years. In other words, it is very important to know if and how much money they have to plan repair funds for façade maintenance in the future.

Often, the solution with the cheapest acquisition cost is selected and this is clearly a “common plaster”. If in 4-5 years the northern sides of these façades start to “grow” and thus require repair, they will be surprised – no one originally took this into account. Apartment associations usually have no extra money in their budgets for such expenditures, and the problem is postponed for as long as possible and the façade is completely forgotten.

It is important to know that synthetic plaster needs periodic maintenance according to the maintenance instructions, i.e. surface cleaning, repair, chemical treatment, and overpainting. This period is 5-7 years.

Today, such maintenance costs approximately 25-30 EUR / m2. The building will remain in scaffolding for several weeks while work is carried out.

It is not difficult to understand that such a façade solution will be more expensive and cumbersome in the long run than the initially slightly more expensive but durable and maintenance-free option.

Thus the cost of an insulated façade = acquisition cost + operating costs!

Marmoroc can be installed in any season - allows you to build a façade quickly and efficiently

Construction prices are generally cheaper in winter

It is a fairly common practice that façade heat insulation works are usually planned only for the summer period.

However, when insulating with wool and no so-called “wet process” is used during installation, the season doesn’t matter. Construction companies often offer a cheaper price in the winter. Therefore, those who plan to work should seriously consider not carrying them out during the winter season.

We offer a ventilating Marmoroc façade cladding system manufactured in Sweden, where light stone façade is laid on a special installation frame without the use of mix or mortar and it is possible to install all year around.

At the same time, the frame creates necessary ventilation chambers, through which the moisture can easily escape from the building.

Thus, the situation is achieved that the building is heat-insulated, the appearance is tidy, and the indoor climate has not deteriorated.

What our clients are saying

At the beginning of 2012, we drove around keeping in mind the renovation plan and looked more closely at renovated houses to find out the pros and cons. The result was dissatisfaction.

After a few years, paint on plastered houses fades, and cracks, there is water and vandalism damage, etc. The conclusion is that the need for maintenance arises relatively quickly and requires new money. The repayment of a loan related to renovations will take 15-20 years. An additional loan for residents would be too much.

In the magazine "Elamu", I guess in a 2011 issue, there was a long and thorough article on the Marmoroc façade stone, and it attracted attention.

Really it was the best solution. The stone is beautiful and colourful, and the colour range is big; it is durable, does not require any maintenance and additional financing, and lasts for decades. If something happens to a stone, replacing it with a new one is a breeze and does not take even a minute. Our house’s façade was completed in 2012 around Christmas, and I have so far replaced 4-5 stones.

We were so-called “first-timers” in Viljandi at that time, but now there are already 10 apartment buildings with Marmoroc cladding - each more beautiful than the last.

Over time, my plastic façade had gathered all sorts of "green" and looked dirty and ugly. Here and there, as a result of different human activities, there were holes in the walls that could not be patched up, and the replacement of the whole panel required the dismantling of the wall with the hole.

Over the course of ten years, Marmoroc has also collected "green" on itself and in the joints, but unlike plastic, Marmoroc does not look dirty and ugly and has retained its original nice appearance.

In addition, replacing a broken Marmoroc stone is simple and only takes few minutes.

Our first goal was to get acquainted with the company's background, search for objects insulated by you, and get feedback from the owners of the objects about both the work done and the company's executive board.
As the answers received from all objects were very positive, our Management Board made a definite decision to choose EREK OÜ for façade heat insulation.

This choice was very right: a brigade of good workers worked on the site, work went smoothly, and the construction site had constant company control; a review of the work was done and the construction contract’s terms were met.

The right façade’s heat insulation together with the replacement of the old heating system reduced heating costs by 50%. This is a very good result.

Both the executive board and residents of the house are very satisfied with the decision made so far.

Our house was renovated in 2016-2017. When choosing the exterior finish, we looked at both plaster and tile finishes. We discussed and considered until Marmoroc ads reached us. Marmoroc - strong, weather-resistant, and virtually maintenance-free, all for a very long time. The neighbouring house became our reference point - truth meets the eye and, in addition to the above, we saw from this house that this stone is also very beautiful. About the slogans - it's too early to tell, but for now we're happy.
