Laconia, NH's Premier Firestopping Company

“Colonial came out to give me a quote on a job. They quickly identified that they would not be the best provider for the work I needed (due to reasons beyond their control), and spent some time discussing with me other options instead. I really appreciate the professionalism and care shown in them immediately saying “there’s a better option for you then our product for this”, instead of trying to sell me a worse solution just to get a job. Thank you, and these guys will be my first call in the future if needed.”

Residential Firestopping Company in Laconia, NH

Firestopping is the prevention of fire travelling from one compartment to another through penetrations, construction joints or any other opening in a building’s fire-resistance rated (i.e. fire-protected) structural element or membrane. Firestopping can be on the interior of a protected assembly where the fire-resistance rated structure separates two areas of a building.

Residential firestopping is very important in many different ways. The reason for this is that when the house catches on fire there are certain places that allow the fire to go through. Residential firestopping will prevent this from happening in the majority of cases. It does not matter if it happens between floors or in walls or in any other place.

Residential firestopping is there to stop the fire before it goes through and does damage. The houses in general are made in a way so that they will burn fast when on fire, but there are many houses out there where people have installed firestopping devices which means it will take more time for the house to get on fire. Residential firestopping devices will be able to burn slower which then gives more time for the fire services to arrive and put out the fire before it gets too bad.

The first thing you should know about firestopping is that there are many different places where the fire can go through so you need to research properly around your house and make sure you know what you are doing before installing anything. In many cases it is a good idea to have more than one type of firestopping so that the fire will not be able to pass.

If you’re thinking of updating your Laconia, NH home to protect it against fires, consider firestopping as one option. For more information on firestopping your home, contact Colonial Green Products who are here to assist you with your every residential fireproofing need.

Commercial Firestopping Company in Laconia, NH

Commercial firestopping allows a building structure to block the spread of smoke and fire so that people can survive in a commercial building for a longer period of time. This is critical in the case of large fires, as they typically result from multiple points of origin and can cover an area larger than one floor.

Firestopping is an important part of commercial building design. A firestop is a system or method to prevent the spread of fire through penetrations or construction joints in materials that are used to separate buildings or portions of buildings for purposes such as temperature control and safety. Firestops require both abilities and procedures to prevent the passage of fire and hot gases through penetrations or construction joints in the fire-resistance rated assemblies of a building.

Commercial firestopped areas prevent the spread of fire to concealed spaces. Commercial firestopping is required for floor penetrations, ceiling penetrations and wall penetrations. Fire-resistance rated construction assemblies are commonly composed of a frame or supporting structure, the noncombustible building materials located on both sides of the frame or supporting structure and an assigned fire-resistance rating.

The assigned fire-resistance rating is the level of time in hours that it will take for a structure to ignite, burn through and collapse when exposed to fire. The type of material used in the construction of the building’s frame or supporting structure is typically specified by one or more governing codes. Commercial firestopping provides an effective barrier against the rapid spread of fire though penetration openings in fire-resistance rated construction assemblies of a building.

If you’re thinking of updating your Laconia, NH business to protect it against fires, consider firestopping as one option. For more information on firestopping your business, contact Colonial Green Products who are here to assist you with your every commercial fireproofing need.

Spray Foam

Spray foam insulation is the process of filling an area with a foam that adheres to the shape of its container.  This type of insulation is resistant to fire, rot, mold and pest infestation, making it suitable for both residential and commercial use.


Cellulose insulation is an environmentally friendly, low cost material that is made mostly from recycled newspaper. It has high thermal resistance properties and can save on energy costs when compared to other types of insulation.

Fiberglass/Mineral Wool Insulation

Fiberglass and mineral wool insulation serves as an air barrier because the individual fibers are too large to fit through cracks and voids that may have developed in an existing building envelope. Fiberglass and mineral wool insulation can block airflow.


The process of fireproofing is known as the field that deals with preventing or minimizing the spread of fire. It mainly focuses on protecting structural members from fire damage, including steel beams, steel trusses, and concrete components/elements.


Firestopping is the term used to define the products which are required for fire protection of structural systems. A void in a continuous barrier could allow a fire to spread throughout that void, thus compromising an entire building.  


Spray Foam Insulation

Spray foam is an air barrier which results in the elimination of drafts, hot spots and cold spots.

Cellulose Insulation

Cellulose insulation is a remarkable improvement over aging insulation in an existing building.
