Spray Foam Insulation Delivers Long-Term Savings

December 07, 2014

Depending on the size and layout of your home, industry statistics show that up to 50% of warm air (in the winter) and cool air (in the summer) leaks out.In a well insulated, well ventilated home, this would not be happening.Needless to say, losing "conditioned" air is a waste of money.So it's easy to see why a well-balanced indoor environment can translate into significant energy savings (and money savings) from season to season.

Installing spray foam insulation is all about value - the short-term benefits and long-term savings.And while it's true that the spray foam product and installation are more costly than other applications, the savings do make the initial, upfront investment worthwhile.The payback period is between 2 and 7 years, but the energy savings endure long after, with lower heat and cool costs adding up to significant savings.

With spray foam insulation, only one application is usually required, again, depending on the scope of the project and the size of house.The finished installation doesn't settle over time (like some other products) and doesn't need replacement, re-application, or topping up.This in itself is cost saving, because an insulation product that needs replenishment every few years can get costly.And that scenario doesn't allow for long-term savings.

Good value is more than just price point - it's also about product features and benefits.For instance, can you really put a dollar value on improved air quality, noise reduction, and home comfort?A good spray foam install will reduce dust, pollen and other airborne particles that have the potential to exacerbate allergies.As well, the application will immediately reduce noise and sound from the outdoors, and throughout the home itself.

As for saving money by engaging in a do-it-yourself approach to spray foam insulation - well, that's just a risky proposition.Because of the unique nature of the spray foam, and because of the complexities of the installation, this is a home-improvement project that is best left to the experts.The risk of doing it yourself, and the possibility of complications, can lead to much bigger problems, not the least of which is additional costs.

The best value when installing spray foam is probably realized during new construction. This is a scenario that provides an opportunity to start from "scratch", and allows for the optimum in project planning, design and application.It's also a situation that could offer labor savings that would translate into overall project savings.A proper, well executed installation like this will provide more benefits than any other product on the market.

Spray foam insulation does cost more than the traditional insulation products that we are most familiar with.At the same time, spray foam saves the most money over the long term, when compared to other products or product combinations.It's the most cost-effective insulation available today, and even a basic cost assessment will illustrate the savings - and that includes cost of product, expense of installation, and energy savings.
