Tips for proper insulation of house in Sydney

By insulation of house in Sydney, we can significantly reduce utility costs and the amount of harmful substances flowing into the air from our household, as well as increase the comfort of the building and the value of the property. But it does not matter what we insulate with what and with what technology. There is an insulation method that we can even do ourselves, but we leave the more severe challenges to a professional! Whether we carry out the insulation or call a brigade, it does not hurt to be aware of specific errors and solutions.

When should we choose which slab insulation method?

There are several methods for insulating the slab. The choice of methods depends on the material and structure of the slab. If we have a smooth concrete slab, we roll out rock wool or glass wool of the appropriate thickness in traditional packaging (sheets or bales) and stack them on top of each other in the attic. However, care must be taken here to ensure that the layer order and thickness are good. Otherwise, we must expect thermal bridges, wetting, and mold.

If there are a lot of drop-ins, zig-zags in the attic, or a complicated multitude of mechanical cables entangling the slab, or if we have a traditional wooden slab, then it is worth choosing the most modern inflatable insulation. In this case, after proper preparation, call a specialist, and there is a good chance they will insulate the slab within a day. The advantage of inflatable insulation is that it is ready quickly, it can be used to protect the floor in winter and summer, even when it rains, it does not create waste, it keeps its shape, it does not collapse, it is fireproof, environmentally friendly and not harmful to health, it reduces CO2 emissions. It does not contain rodenticides, fungicides, or flame retardants. Mold cannot form; it lets moisture through, and humidity does not stop in the attic insulation.

It has a few more positive properties:

  • water-repellent,
  • hydrophobized,
  • treated with a water-repellent material,
  • does not absorb moisture or moisture,
  • and has a high vapor permeability.

Since it is not sensitive to temperature fluctuations, it does not move or warp, the insulating material does not collapse, and thermal bridges do not form. It has good air permeability; if we do not stuff the building, our house can “breathe.” It also has good soundproofing properties. On the other hand, its water-holding capacity is exceptionally high, so constant soaking water is not harm, even in roof insulation. Blown-in rock wool belongs to the A1, non-combustible fire protection category.

What about facade insulation?

Fa├žade insulation also has some fundamentally essential rules. The first is to prepare the house for insulation properly. In other words, assessing the condition of the plaster and masonry and the openings’ designs is necessary. How we will solve the insulation around the doors and windows, and special attention must paid to meeting the structural elements. Especially at the junction of the facade and the slab, less qualified professionals tend to forget the insulation integration, resulting in being created in the newly insulated building.

It also happens that the customer decides on a 15 cm thick insulating material, but the contractor convinces him that it will be OK with 5 or 10 cm xps sheets. This is a problem because the right thickness is significant for the insulating material; a 5 cm styrofoam will be less effective than a 15 cm styrofoam. In hindsight, it’s too late; applying another layer of insulating material is expensive, and there are many possibilities for mistakes.

In addition to the appropriate thickness, it is also essential not to DIY insulating materials of different thicknesses and quality. Because we provide another opportunity for thermal bridges, wetting, and mold. Moreover, even the glued insulation material can fall off if the glue is poorly process underneath, water has formed, etc.

Hiring the best insulation installers in Sydney is a wise investment, as it not only reduces house utility bills but also contributes to environmental sustainability by lowering carbon footprints.

What material should we work with?

Rock and glass wool are the most suitable materials for insulating the attic, roof, or slab. These insulators can also used in inflatable form. The primary raw material for glass wool products is glass scrap, i.e., the by-products of flat glass factories. This requires a large amount of quartz sand, one of our planet’s fastest renewable raw materials. Glass wool also has excellent fire protection properties. Glass wool and rock wool insulation protect our home from extreme weather both in winter and summer. In the summer, it prevents the building from heating up, so you need to use the air conditioner and the fanless, and in the winter, it preserves the heat. It is not necessary for the heating to be on all the time.

It is worth using xps sheets or graphite polystyrene sheets for facade insulation. This insulating material is made from pre-foamed polystyrene beads. It is widespread in facade thermal insulation, as it is easy to work with and a cost-effective method. It is attach to the facade by gluing and doweling. Reinforced, more moisture-resistant polystyrene sheets are used for plinth insulation. With a properly executed system, we can expect a long service life. Its advantages are good thermal insulation, low weight, easy to transport, easy to shape, simple to install, cost-effective solution, applicable to almost all wall structures, load-bearing, and step-resistant.

Graphite polystyrene thermal insulations insulate better than traditional white styrofoam insulation materials. They are similar to plain, white polystyrene insulating material, but with the same thickness, they have about 20% better thermal insulation. They are mainly use for facade insulation.

When is it worth starting the implementation?

We can perform the attic insulation at any time, as well as the roof insulation, if the roof can access from the inside. The situation is different with the underfloor and facade insulation. You have to pay attention to the drying temperature of the adhesive materials. When we schedule the work processes, we can group attic insulation and slab insulation for winter and facade and plinth insulation for spring.
