The demand for rigid foam insulation has increased exponentially in the last couple of years. This is because they are considered as a cheap and effective way of keeping the house warm. The installation of these rigid foams over the wall studs is pretty easy and can be done by taking care of some simple measures at the same time following proper steps.
Step 1: Preparing the Walls
Prepare the walls of the area to be insulated. Check for any edges that might be jutting out or any distinct cracks. Rectify them by hammering the edges flat and fill the cracks. Make sure that the studs are smooth and are clean enough for the adhesive to be effective.
Step 2: Measuring and Marking
With the help of measuring tape, calculate the total size into which the foam boards have to be cut (one wall stud corner to the other). It is advised that it should be double checked for any mistakes. Miscalculations would lead to wrong sizes being cut which would be useless. In such a case, additional units of boards would have to be brought. Accurate measuring is important. Use the marker and the measuring tape to make appropriate marks on the board. While cutting the boards, these marks would be used as reference points. Place full length straight scales so that no problems are encountered during the cutting process.
Step 3: Cutting
Using the reference marks, cut the foam boards with the help of hand saw. Once again, accuracy is important. Be precise while making the cuts. Since these need to be placed on the walls, any error due to misjudgment would lead to repeating the whole process again. A good method would be to use the complete face of the saw from top to bottom in one stroke.
Step 4: Placing on the Wall
Stick the foam boards with the help of the adhesive between the wall studs. The adhesive needs to be of good quality, preferably superglue or an industrial adhesive. Once they are positioned appropriately, hammer them to apply pressure so that they get stuck firmly. Leave the setup to dry for an hour following which, place screws at equal distances in both horizontal and vertical directions. The use of washers would result in a firmer grip.
Step 5: Covering
Cover the foam boards with drywall so that it looks elegant. This would cover up the gaps between two or more boards which will reduce loss of heat. Additional procedures that can be followed include water proofing the walls. Implement them as deemed necessary.
The above mentioned five steps are more than sufficient and if followed can guarantee a warm interior for a minimum of 25 years. Once installed, there are no additional maintenance requirements. The initial installation cost may seem higher but it evens out in the long run and the average cost reduces significantly. Since this is a permanent fixture, no costs on buying heat would need to incurred till the time the insulation is working effectively and efficiently.
