Spray Foam Insulation - Today's Most Sought After Option

December 04, 2014

In recent years, spray foam insulation has been duly recognized for its definite advantages over other insulation products.Spray foam is not particularly well suited as a DIY project, and it's certainly not the cheapest approach to insulation, but it remains the most sought-after installation technique today.Taking into consideration the product advantages, and the relative cost of product and installation, the question is - is it worthwhile long-term?

Home insulation should really be a one-time project.It should be done right the first time, and it should be done once and for all.The spray foam product itself has evolved in many ways over the years, and today it has become the leading insulation product amongst industry professionals across the nation.It's an innovative product; its very versatile in application; and it delivers more benefits and better results than any other product.

Generically, it's known as polyurethane foam, and can be easily applied through the entire home - it's an excellent sealant and works well in virtually any space where it's applied.For large, expansive areas, spray foam acts like a "thermal envelope", providing exceptional sealing coverage and R-values that are above and beyond the capacity of other insulating products.A good install will deliver the best insulation performance available to you day.

A professional installation, using a quality spray foam product, will bring many benefits to a building structure:indoor air temperatures are better balanced; moisture levels are better controlled; and air circulation and air quality are enhanced.The whole idea is to create an indoor environment that operates at full potential, provides energy efficiency, and brings comfort to the occupants.In fact, spray foam insulation also contributes to energy savings.

The latest advances in HVAC systems and temperature control mechanisms have resulted in energy savings that every consumer wants.As well, there have been significant changes in the construction industry, in terms of delivering energy efficiency and conservation.All things considered, the spray foam approach to insulation can contribute to energy savings between 30% and 50% yearly - and that makes for substantial savings over the long term.

There is no better sealant than spray foam.It prevents pollens and dust from infiltrating the indoors, and therefore allows for better air circulation.Those who suffer with allergies from season to season notice a difference, almost immediately.As it is, spray foam is mold resistant (which is important in the attic) and does not provide a welcome environment for insects or rodents.It has also proven itself as an effective noise reduction barrier.

Spray foam insulation is known to be a more costly application than other products.Best left to an insulation specialist (it's not a good DIY project), both product and installation are more costly than other approaches.However, the benefits derived from a good install will far outweigh the upfront costs, especially when considering the long-term savings.Simply put, spray foam is a premium product, with long-term benefits, and measurable savings.
