Instructions for replacing the thermal insulation of summer houses

Instructions for replacing the thermal insulation of summer houses

The suitable thermal improvement of a summer house can extend its occupancy into the colder months of the year. This means higher revenue for an owner renting out such a thermally improved summer house to tourists. One example of a summer house in Poland is the ever-popular Brda-style cottage. Here it stars as an example for these instructions.

From the outside, the summer house is lined with hard PIR-core sandwich panels, featuring the highest thermal insulation performance rating, A++.

 

 

How much does the thermal improvement of a summer house cost?

The recommended thermal insulation thickness to make a real difference is 100 mm.

  • Thermano sandwich panels: from 70 PLN/m2
  • Labour*: from 35 PLN/m2

* Thermano sandwich panels are easy to install. A DIY beginner can install them on their own. The sandwich panels are simple to trim and to cut holes in. The butted joints can be easily secured with aluminium tape.

 

Step-by-step thermal improvement of a summer house

1. Appropriately modernised summer facilities allow for the extension of the tourist season by some additional months, which means higher profits for Investors or users. An example of such a facility is a “Brda” summer cottage.

2. Modernisation should be started with the disassembly of the old roof covering. First, all the interfering flashings must be disassembled. The roof is very often covered with eternit, which must be removed and utilised. Entrusting the eternit removal to a specialised company holding permit for the performance of such work and equipped in special personal protection measures is recommended.

The disassembled eternit panels must be carefully placed on pallets and then protective film should be applied to prevent asbestos fibre from dusting during storage, transport and utilisation.

3. The next stage of modernisation is technical condition control: the exposed roof truss, substructure and membranes. In the case of a negative result of the evaluation, the faulty elements must be exchanged or repaired. In the facility presented here, the roof truss turned out to be dry and technically sound.

4. The next step is the preparation of thermal insulation materials. In this case, Thermano panels of hard polyurethane foam were used for the insulation of the roof and the gable wall. This material is characterised with the highest thermal resistance among the commonly used thermal insulation materials.

5. Two layers of Thermano panels were applied in this project: 80 mm and 50 mm The panels must be properly cut to size. It can be done using any cutting tool.

6. Then the first layer of thermal insulation is attached using screws. The Thermano panels are installed in a staggered manner. The second layer of Thermano panels is installed in the same way as the first one.

7. The next step involves the placement of vapour breathing membrane and the assembly of battens.Thermano panels are not only resistant to the activity of various chemical substances, but also to rodents, fungi, mould, precipitation and water vapour. This is especially important in the case of summer cottages, which are located near forests or water reservoirs.

A double layer of Thermano panels will ensure excellent thermal insulation properties. A facility modernised in this way can be used in early Spring and late Autumn and with an appropriate heating source – also in winter. In the latter case, investment in Thermano panels also allows for significant savings on heating. An additional advantage of the assembly of PIR panels is maintaining a comfortable room temperature even during summer heatwave.

 

If you install a Thermano thermal insulation system....

  • You will extend the rental period of your summer house into the colder months for many years to come.
  • There is no worry that the thermal insulation will degrade over time. Thermano resists moisture and liquid water, as well as infestation by rodents or birds.
  • You reduce your heating and cooling costs, leading to savings and more revenue, while also reducing your carbon and air pollutant footprint.
