Insulation is beneficial to maintain pleasant temperature indoors without any need for cooling or heating device. Less use of appliances means a significant reduction in your utility bills.
The challenge property owners experience is choosing the perfect insulation type or material. Insulation materials range from fiberglass, wool, cellulose, natural fiber, rock, & slag, firm foam boards and reflective foils. Extensive materials oppose conductive and less degree convective flow of heat in a building cavity.
The solid foam boards trap gas or air to resist the flow of heat. Reflective foils reflect glowing heat away from the living places making them very useful in keeping room ambiance cool. Other less common insulation materials are vermiculite, perlite, phenolic foam and cementitious.
Below is a rundown of different insulation styles to help you make an informed decision.
It is also called batt & roll insulation. Batts & rolls are designed from flexible fibers including wool, cotton, mineral, and synthetic fibers. The rolls are continuous and can be cut to fit. You can buy batts & rolls with or without facing. Facing acts as air or vapor barrier. Blanket insulation is applicable on unfinished walls. It is best suited for joist and stud spacing, which is entirely free of obstacles. It is a DIY project, which is relatively inexpensive.
Firm foam board insulation
Any part of your home [roof to foundation] can be insulated with rigid foam panels. Foam boards are incredibly useful in attic hatches, interior basement wall, and exterior wall sheathing. Excellent thermal resistance is maintained. Heat conduction through the structural elements like steel and wood studs gets reduced. Foam boards are designed from materials like polyurethane, polystyrene, and polyisocyanurate.
Loose fill & blown-in insulation
In the loose fill, small insulation particles like fiberglass, cellulose, or foam are used. This insulation material can match any gaps without disturbing finishes or structures. Loose fill insulation is suitable for retrofits or in locations, where other insulation kinds are difficult to install. Experienced installers need to be hired because they are capable of attaining correct R-value and density of blowing loose fill materials.
Radiant barrier & Reflective insulation system
Radiant heat gets reflected with smooth aluminum foils used in the insulation system. Radiant barriers are usually installed in home attics with an aim to decrease summer heat and lower cooling costs.
Rigid fibrous board insulation
Mineral wool or fiberglass materials can withstand high temperatures. Fibrous boards designed from these materials are used in insulating air ducts. The boards are available in thickness ranging from 1” to 2.5”.
Sprayed foam & foam-in-place insulation
The liquid foam material can be injected, poured, sprayed, or foamed-in-place. It is the best way of reducing air leakage from cracks and holes. Smallest cavities can be filled to create an effective air barrier.
- Open cell foam: Semi-rigid foam material used offers spongy texture allowing water to pass without absorbing but resist air flow and water vapor. Open cell foam must not be applied below ground level.
- Closed cell foam: Closed cell foam is best for areas, where moisture can be an issue. It is dense and rigid, so resists water intrusion. Closed cell foam has excellent R-value, which offers substantial resistance to air leakages and moisture. It is costly to install.
Traditional batt insulation is much cheaper than foam insulation products. However, foam insulation offers strong air barrier and high R-value, which reduces costs and tasks connected with home weatherizing like applying vapor barrier & house wrap, caulking, and taping joints. People living in Slovakia can benefit from the insulation program. Slovakian government supporting insulation allows interest-free loans to citizens with a maximum maturity of 15 years.
Now, you are well familiar with different styles of the insulation system. Choose material and type according to your property needs and budget. Take professional help, if necessary without hesitation.
