Residential insulation

Residential insulation of existing home

Insulation is crucial for ensuring comfort and well-being at home
If a building or a home is poorly insulated, it will constantly be losing heat.

This can lead to significantly increased energy costs. The purpose of insulation is to eliminate or reduce heat transfer between a cold area and a warm area. It works by trapping heat inside in winter and keeping the house cool in summer.

Signs of poor insulation

Northern countries’ climate is straining the build of many homes. The quality of the insulation is an important aspect to look at to create a comfortable room temperature. Some signs can show you that your house’s thermal insulation is either insufficient or inadequate. The signs to watch for vary according to seasons:

In winter

  • Walls which are cold to the touch
  • Cold floors
  • High heating costs
  • Uneven heat distribution throughout the house
  • Molds growth on walls

In summer

  • Warm indoor air
  • High air conditioning costs
  • Inefficient air conditioning
  • Mold appearing in the basement

The main goal of proper insulation is to reduce heating and cooling costs significantly. Whether your house has been built many years ago or if it’s currently under construction, Isolation Multi-Services can help you make it happen anywhere in the greater Montreal area.

What are the materials available for insulating an existing property?

There is a wide array of materials one can use to insulate a property, each one having its set of specific features. The most commonly used materials are urethane, spray polyurethane foam, injected-blown cellulose, and wool mat. Polyurethane is the most efficient material in the industry. However, injected-blown cellulose is recommended for wood frame walls or for insulating attics. Urethane insulation is versatile, as this material can be used as an air and vapor barrier and for thermal insulation. As for wool mat, it is an excellent cost-efficient alternative.

Improving your home’s insulation is a project that requires investment. However, when such projects are carried out by well-trained professionals such as the team at Isolation Multi-Services, you can enjoy substantial savings over the medium and long term.

Soundproofing for existing buildings

In the greater Montreal area, several buildings were built at the beginning of the last century. Buildings located in the Old Port, on the Plateau-Mont-Royal or downtown as well as ancestral homes in the Montérégie and on the North Shore often face noise problems. Isolation Multi-Services has unrivalled expertise in the soundproofing of existing walls and ceilings.

Our state-of-the-art equipment allows us to insulate existing walls and ceilings by drilling 3-inch diameter holes in gypsum. Once the sound-absorbing product is added, the gypsum washers can be replaced, and the wall can be plastered.


Existing home residential insulation

It is always possible to improve the insulation of an existing house, whether the insulation needs to be done from the inside or outside. The principle of the passive house, as established by Passivhaus in Europe over 20 years ago, is that the energy consumption of a house should not exceed 15 kilowatt hours (kWh) per square meter. If you believe your house is too energy-consuming, it might be time to improve its thermal insulation.
