Closed Cell Spray Foam Insulation

Closed-cell spray foam insulation is renowned for being a superior material for both residential and commercial projects. Its unique application allows it to improve energy-efficiency while also enclosing conditioned air inside the structure, thus, reducing the amount of money spent on wasted energy. It’s also virtually impervious to moisture, preventing the loss of R-value, as well as the growth of mold.

Because it will not shrink or settle, its high R-value – it can achieve an R-20 at 3 inches and R-41 at 6 inches – and acoustical performance lasts the life of a structure. It is manufactured on site by combining an isocyanate and a polymeric resin through state-of-the-art equipment. Properly installed, closed-cell spray foam insulation can adhere to a wide variety of substrates including concrete, metal and wood.

Applications for closed-cell spray foam insulation include:

Roofs: Spray foam insulation can be used as a re-roofing material, applied directly on the existing roof structure, providing two important benefits: 1) waterproofing and 2) increased R-value. This application is more commonly seen in commercial building rather than residential.
Exterior walls: One of the positive attributes of spray foam insulation is its versatility. It’s compatible with many wall types and can be sprayed onto the exterior sheathing in new construction projects, or assimilated between stud cavities in retrofit situations.
Interior Walls: Upgrading insulation with spray foam insulation allows you to benefit from fewer drafts, more consistent indoor temperatures, better indoor air quality, and reduced noise pollution. Similar benefits can be achieved when installed under floors.

Ductless Cooling & Heating Options for a Home or Business

Believe it or not one of the most devastating aspects of any commercial or residential HVAC system isn’t the compressor, condenser, blower motor, or any of the other moving parts; it’s the thing that does supposedly nothing – the duct system. Duct systems not only carry allergens, dander, and debris to every room in the house, they are also a huge reason for energy loss simply in the transfer of air, never mind the leaks.

It’s not hard to see why many homes and businesses are researching their options for a ductless HVAC system. Eliminating the path of heated or cooled air from where it is handled to where it is delivered produces fewer allergens while also reducing energy loss. With that said, here are some of the ductless HVAC options available for homes and businesses, whether they are building new or replacing existing components.

Ductless Mini Split

The ductless mini split air conditioners are a trendy choice for both homes and businesses for a number of reasons. First of all, the lack of ducts helps lessen energy loss and creates fewer allergens jostling around the room. Ductless systems contain a compressor/condenser outside the home and copper lines carrying refrigerant to an indoor fan unit. This one-to-one setup proves ideal for cooling home renovation additions without trying to tap into the existing HVAC system or for use in a room that is unreasonably warm (facing the sun) without taxing the entire central air conditioner. With the installation of a heat pump, any ductless A/C systems will also supply warmth, serving as a full HVAC unit.
Single zone ductless systems are available in the most basic form for something like a lake house or rarely occupied room. They are also manufactured in more advanced versions that feature programming, motion sensing, wi-fi automation, and 3D airflow.

Multi-Zone Ductless Split

One hindrance of the single zone system is that the compressor can only cool one fan/vent component and therefore only one room. The easy solution is a more powerful multi-zone ductless system in which 2-4 ‘heads’ can be installed in different zones of the home or business. This proves a more cost-effective solution than running central air in a smaller square-footage home or a part-time residency. Multi-zone units also work great in a small office where multiple rooms may all want to have different temperatures (conference room, cubicles, break rooms, etc.).

Dual Condenser Units

For the most part, the maximum output that any single condenser can supply heating / cooling to is four rooms (or four fan / head units). The solution in larger homes or offices then is to install a second outdoor condenser/compressor unit which increases the output to between 6-8 different rooms. The configuration can be manipulated to the property owners needs whether they want a single control, multi-controls, or have heating and cooling in specified zones.

Installation Types

Another benefit of ductless systems is that the indoor fan units feature multiple mounting options. The fans can be placed on a wall, on the ceiling, recessed in either the wall or ceiling, or with concealed ducts. The temperatures can be controlled with a remote control and rooms are conveniently cooled without having to block the view with a window A/C unit or lose energy through a ducted system.

What Brand

Everyone has different needs and desires. That’s why Rhode Island Retrofit does not sell an exclusive brand. At Rhode Island Retrofit we install Fujitsu Ductless Systems, Mitsubishi Ductless AC, LG Ductless Systems and

The great thing about these various HVAC systems is that they provide options. Commercial or residential customers are not limited to a ducted air flow system and can instead choose heating and cooling options based on their home layout, health history, budget, and needs.

5 Places To Consider Adding Extra Insulation In Your Home

When you live in the Northeast, you learn that home insulation is a very important part of your home. Not only can it keep your home at a comfortable, even temperature, but it can also help you save money on your energy bills. While you may already think your home is insulated, there are several areas that we recommend considering adding insulation:

Attic Access Door

Even if your attic has sufficient insulation, you’ll want to make sure your attic door has it too. Attics get cold during the winter months, and whether your door is built into the ceiling or is a walk-in door, it can easily let that cold air out into the rest of your home. Insulate it properly and you’ll eliminate cold drafts and keep surrounding rooms warmer.


While cantilevered floors are a great way to give your home some character, you have to remember that they sit beyond the exterior wall below. This means they don’t receive any warmth from the room below and can get cold. Installing insulation between the floorboards and the exterior-facing soffit can help protect the floors from cold outside temperatures.

Ceilings/Walls Next to Cold Spaces

Ceilings and walls that are adjacent to a cold space (such as an attic, a garage, or a crawl space) may require extra insulation in order to protect the room from the colder temperatures next to it. Consider extra insulation especially if the room is one you spend a lot of time in.

Joist Spaces

Many older homes don’t have insulation between their first and second levels, which allows air to easily flow from one floor to another. By installing insulation underneath the floorboards between the spaces of your home’s joists, however, you can reduce airflow and regulate the overall temperature of your home more easily.

The Difference Between Fiberglass And Spray Foam Insulation

When choosing insulation for your home there are a couple of different choices for your home. There are certain advantages to choosing the right insulation for your house. The two most popular options are fiberglass and spray foam insulation. When making a choice in insulating your home consider the following options.

Fiberglass is still the most popular insulation used in homes today but Spray foam insulation is becoming more popular. The fiberglass insulation is much cheaper to install then spray foam insulation. The cost of installing spray foam insulation is at least three times the cost of the Fiberglass insulation.

Another aspect of the two different types of insulation is the spray foam has to be done by professional installers so this also is added to the cost. Fiberglass insulation can be installed by the homeowner themselves. These two aspects have to be looked at by the homeowner.

With all the added costs of buying spray foam insulation is it worth it. Fiberglass insulation is not as energy efficient as spray foam insulation. If using spray foam insulation you can cut your energy bill and lower it by as much as fifty percent. So the energy efficiency of the spray foam makes up for the more expensive price tag.

Fiberglass insulation is not as energy efficient and has pockets where the airflow escapes to the outdoors. These fiberglass pockets create lots of holes where the air can escape. This also means the r-factor is lower in the fiberglass insulation. This is especially true in cold climates and the fiberglass insulation lets in the cooler air in cold climates.

Another point to note is once the insulation is installed in both of these installations they have one major difference. The fiberglass insulation loses it r-factor value over time whereas spray foam does not lose its r-factor over time. The r-factor is a measure of how much air can be kept from flowing out. The greater the r-factor the higher the number.

With the price of spray form being more expensive is it worth the cost. Yes you can increase your energy efficiency by quite a bit and recover your costs of installation within three to four years. The spray foam insulation has to be properly done by an expert so to get all the areas. If this is done properly then you will save lots in your energy costs. It will last longer than the fiberglass insulation also.

Fiberglass insulation can be installed by the homeowner but you have to make sure to wear protective gloves and mask so you don’t breath the fibers which are known to cause cancer. The spray foam is safe when it dries but you need protective clothing and mask to keep from breathing and can cause respiratory problems. With the higher efficiency of the spray foam it is vastly becoming more popular.
