Does attic insulation become less effective over time?

Attic insulation can last 80 to 100 years, although it loses its energy efficiency benefits over time. The professional advice of certified attic specialists is to update it every 15 years to ensure that it continues to function properly. A common question that people ask is whether it really matters that their insulation is damaged or old. The answer is a resounding yes, the state of your insulation can have a huge impact on the energy efficiency of your home.

If the insulation has been damaged by water or rodents, it is absolutely necessary to replace it. Insulation lasts much longer than you think. According to the International Association of Certified Home Inspectors, household wrap, spray foam and adhesive tape can last more than 80 years or longer. Cellulose, foam board, white loose filler, rockwool, fiberglass and loose filler can last longer 100 years old.

However, these conditions are only for insulation under ideal conditions. If the insulation is placed in an environment that is not ideal, the life expectancy of the material can be significantly shortened. The lifespan of attic insulation usually lasts between 10 and 15 years, but its lifespan can be affected by several factors, such as the house climate, ventilation and pests. Once again, all these numbers are encouraging, but you should not rely solely on them and forget that the insulation of your attic exists.

If you're not sure if you need to replace your insulation, consider scheduling an inspection with Attic Construction. Attics are difficult to insulate because they tend to be irregular in shape and have many nooks and crannies. Removing the old insulation from the attic before adding a new one will make it easier for you to properly install the new insulation materials, which will ensure an even distribution and will be effective in keeping the house warm in winter and cool in summer. Similarly, if the attic is poorly ventilated, heat and humidity can deteriorate the insulation. Once you determine the need for new insulation, hire professional insulation contractors to replace old or degraded insulation with new, modern materials.

A simple inspection will let you know if your insulation has been installed incorrectly or is inadequate. Schedule a visit to a reputable attic insulation service once the attic insulation has started to fall, break, move, thin and get wet. Installing insulation properly can help reduce utility costs and maintain a stable temperature in the home; however, insulation is often not installed properly or is inadequate. Fiberglass insulation or block insulation, along with other types of insulation, should be checked from time to time for physical and water damage.

When used in an attic, insulation with fiberglass blocks can help keep the attic cooler in summer and warmer in winter. Ultimately, taking the time to remove old attic insulation before adding a new one will provide you with several benefits that will improve the efficiency of your home. Old insulation may contain toxins and harmful chemicals that could contaminate the new insulation.
