How to safely install insulation?
Installing the insulation on empty joist spaces is quite straightforward. Pick a batt and tuck it into the joist spaces. Push it up straight to the ceiling wall and then pull it back slightly so that the fiberglass fluffs accordingly. Tuck it in tightly into the space where the ceiling meets the walls.
What you should know about installing insulation?
- It can boast a much cleaner and pollution-free production process when compared with other alternatives
- When it is removed from a building as the result of a renovation or remodel, it degrades without contributing harmful chemicals or off-gassing into the soil, water, or air.
- It has high energy-efficiency ratings
How much insulation should be installed?
To achieve this standard, you will normally need at least 70mm of high-performance foam insulation, or 150mm of mineral wool, but this will vary depending on floor type, shape and size.

Does foil insulation need an air gap?
You MUST have an air gap in order to get either the emissivity quality or the reflectivity quality that you're looking for, otherwise the foil will not work as a radiant barrier.
Does reflective insulation really work?
Reflective insulation can block 95% of radiant heat and provides superior thermal performance. Reflective insulation reflects escaping heat back in the direction of your home's interior. By harnessing the loss it lowers your heating bills.
Does reflective insulation keep heat in?
Unlike mass insulation, reflective insulation is able to keep heat in and reflect heat away. Mass insulation material like fiberglass and foam merely slow down the transfer of heat; they do not reflect heat away, nor do they keep heat in. Reflective insulation has the ability to control the transfer of radiant heat.
How much does it cost to install a radiant barrier?

Is reflective insulation better than fiberglass?
The U.S. Department of Energy reports that reflective insulation is the most effective at preventing downward heat flow, making it a better choice for roof insulation where keeping heat out is the most important factor.
Is aluminum foil a good radiant barrier?
Aluminum foil has the radiant barrier properties of high reflectivity and low emissivity. That means the foil reflects much of the roof's heat back upward. The low emissivity property of the foil reduces the amount of heat that the foil radiates on through to the attic insulation below.

Can you use insulation in a retrofit?
Foil insulation can be applied in both new and retrofit constructions.
How to make reflective insulation?
Cutting this material requires a sharp blade in a utility knife and a straight edge. Place the insulation on a hard, flat surface before you cut. A scrap piece of plywood is perfect for this job. Mark the foam board on the rear of the insulation. Place the knife at the top of the piece and cut straight. This will cut through the foam and score the aluminum underneath. Run the knife again on the aluminum sheet and you will have cut through.
How does reflective insulation work?
Reflective insulation is a great product that can be used to help save money on heat ing bills by placing it behind hot water radiators. This type of insulation is built with reflective properties that do not absorb heat but direct it in another direction. Radiators are a common sight in many older homes. They provide a lot of great heat, but they lose a lot in the direction of the wall. With reflective insulation installed behind the radiators, you can keep your room heated more efficiently and save money in the process.
How to measure radiator for insulation?
Use a tape measure and find the measurements for the length and width of the radiator. Then add another 8 inches to the length and the sides of the radiator. This will give the insulation enough room behind to continue reflecting the heat 8 inches away.

The process is more tricky than installing foil insulation during the construction of a property, but can be undertaken if need be.
How To Install Foil Insulation On Walls?
This is because it is difficult to get into the plaster once it is set, without cutting through .

The reason it is sometimes referred to as reflective insulation is, because on hot days, the reflective surface of the insulation panels literally reflect the sun rays back out, stopping them from entering your property.
Why use foil insulation?
Basically, a foil insulation panel works to reduce the heat transfer effect that occurs during thermal radiation. The reflective surface acts as a barrier to reflect the heat from one side of the panel, preventing it from transferring to the other side.
Why do you need insulation during construction?
This is because it protects the inside from rain, meaning work can carry on without bricking or cladwork being complete.
How does radiant barrier insulation work?
RadiantGUARD® radiant barrier foil insulation installed in an attics can reduce attic temperatures by up to 30 degrees when stapled with a staple gun to the underside of roof rafters by REFLECTING up to 97% of the radiant heat that strikes its surface thereby reducing heat transfer from the attic to living spaces resulting in lower utility bills. This method also reduces the heat subject to attic mounted AC duct work thereby allowing them to work more efficiently.
How to keep your attic cool?
Start early in the morning when your attic is at its coolest. Carry all of your radiant barrier and tools into the attic to avoid unnecessary trips to and fro. Keep plenty of water on hand and drink even if you don't think you're thirsty; especially in the summer months.
How effective is radiant barrier?
A radiant barrier can be very effective at BLOCKING radiant heat when installed in conjunction with roofing and siding material, however, the radiant barrier MUST be installed with an air space on at least one side of it. As long as there is at least a 3/4" air space on either side of the radiant barrier, the application will be effective at BLOCKING radiant heat. For more information on why a radiant barrier must have an air space on one side of it to be effective, please see our What is Radiant Barrier page.
What is radiant barrier on counter?
The picture below shows a batten/counter batten system with a slate/tile material with a radiant barrier on top of the counter battens. The radiant barrier is installed on the top of the counter battens in non-watertight applications. This allows the radiant barrier to remain dry while also achieving the 3/4" air space requirement.
What are some examples of radiant barrier roofing?
Metal, tile, and slate roofing systems are examples of such roofing systems where a radiant barrier can be easily incorporated. Equally as important as the air space on a radiant barrier is the requirement that a radiant barrier remain clean and dry in any application.

How much space between rafters?
Install unfaced mass insulation between rafters ensuring a minimum of 1" ventilation space between the mass insulation and the underside of the roof decking.
