There are few things that modern homeowners deal with that are more annoying than ever-present drafts. This is especially true in South Central PA, where winter drafts can make it difficult to ever truly relax at the end of a long day. While areas of the home like the basement and attic can play a major role in overall energy loss and transference, the sidewalls of a home can be where drafts originate and must be dealt with in order for the problem to ever be truly fixed.

If you're looking for a solution that can cut drafts down entirely, look no further than high-performance sidewall insulation.

Why sidewall insulation?

There are a number of reasons why it's important to insulate the walls within a home, including noise suppression and more stable indoor temperatures from room to room. Sidewalls are even more important than others to insulate, however, as they form a major part of the building envelope and are in contact with outdoor, unconditioned air. If your sidewalls aren't properly insulated and air sealed, it stands to reason why they would be set up for drafts and other similar problems.

That air that's rushing into your home? It's coming from your sidewalls, and it's time to do something about it.

Superior product and performance

Energy savings

Using the Nu-Wool WALLSEAL System, Nu-Wool Premium Cellulose Insulation is installed in wall cavities, eliminating the voids and air pockets common with berglass insulation. Our installers of the WALLSEAL System are factory trained and certified professionals, and are equipped with specialized machines designed for this application. The increased efficiency of the Nu-Wool WALLSEAL System, along with Nu-Wool Premium Cellulose Insulation in the attic, saves homeowners as much as 40%* on heating and cooling costs.

Air Sealing

Most buildings insulated with Nu-Wool Premium Cellulose Insulation meet or exceed the air tightness requirements of the 2012 International Energy Conservation Code without additional air sealing products. This is made possible through the high density of Nu-Wool Premium Cellulose Insulation, particularly when installed in wall cavities using the Nu-Wool WALLSEAL System, which reduces air infiltration and makes a tighter building envelope.

Green Product

Nu-Wool was GREEN long before Green Building existed. With its low embodied energy, high recycled content and superior energy saving performance, Energy Care Cellulose Insulation is without question the GREENEST insulation product in the marketplace. The application process of Nu-Wool Premium Cellulose Insulation is also GREEN, because all excess sprayed insulation is brushed o the wall and then vacuumed up to be reused resulting in no product waste. Even the product bags can be recycled!

Acoustical Performance

In full-scale wall testing, Nu-Wool Premium Cellulose Insulation greatly reduces the movement of airborne sound from one room to an adjacent room. This added benefit of Nu-Wool is especially important for apartments, condominiums, offices and hotels. Buildings insulated with Nu-Wool Premium Cellulose Insulation have a noticeable "quietness". The sharp sounds that easily transmit through berglass insulated structures are subdued by the increased mass of Nu-Wool Premium Cellulose insulation.

Competitively Priced

Nu-Wool Premium Cellulose Insulation delivers increased energy savings and superior sound control. Yet it is competitively priced compared to berglass insulation, making it one of the best values in the insulation market.
