Which is the Cheapest Way to Insulate a Roof?

Budget-friendly insulation is the order of the day for most citizens of Pakistan. Discover the benefits of Insulate a Roof to improve energy efficiency and comfort. Primarily, the costs depend on the material quality, experts’ visits, area coverage, and climatic changes. To understand the dynamics of roof insulation, you need to connect with Lakhwa Chemical Services, one of the best companies in Karachi.

Is it Worth Insulating a Roof?

Layering your roof is an effective way to minimize heat loss and reduce expenditures. Insulation can prevent ice dams (water refreezing on roofs) and ensure safety for residents. Moreover, it helps slab-on grade structures to remain cozy and cool in warm conditions. Lastly, outside noise is subdued by minimizing effects of air movement.

Money-Conserving Roof Insulation Methods

1. Spray Foam Insulation

Polyurethane or latex spray is applied to the underside of the roof. This insulation type aids in sealing crevices, blocking moisture, and providing a reinforced heat-resistant layer. It can be used on targeted areas or the entire roof.

Benefits

• Long-lasting
• High R-value
• Eco-friendly

Drawbacks

• Foul-odor
• Airtight

N.B. The cost of spray foam insulation is Rs. 100 per board feet. (excl. of labor cost)

2. Batt Insulation

Batt or Fiberglass Insulation is DIY-friendly and convenient to install and maintain. It is available in rolls with varying R-values. This insulation can fit around roofs, rafters, and joists. Lastly, batt insulation is optimal for sound dampening.

Benefits

• Moisture-resistant
• Readily available
• Optimal choice for garage, basement, and attic

Drawbacks

• Respiratory Issues

N.B. The cost of batt insulation is Rs. 150-200 per square feet. (incl. of labor cost)

3. Blown-in Insulation

This covering is made from cellulose, fiberglass, or recycled materials. It is an excellent choice for filling large-sized areas, such as roofs. In addition, it can be fitted into hard-to-reach places too. Blown-in insulation is non-flammable and suited for cold regions.

Benefits

• Moderate to High R-values
• Eco-friendly
• Adaptable

Drawbacks

• Moisture-prone
• Need careful installation

N.B. The cost of blown-in insulation (fiberglass) sheet is Rs.250 to Rs.350 per square feet.

4. Structural Insulation Panels

Also called SIPs, structural insulation panels are popular for residential structures, especially bungalows. These coverings help reduce energy and maintenance costs.

Benefits

• Quick construction
• Weather-proof
• Flexible design

Drawbacks

• Moisture-prone

N.B. The cost of structural insulation panels is Rs. 1000 to Rs. 1500 per square feet.

5. Rigid Insulation Boards

Rigid boards are made from polyiso, XPS (extruded polystyrene), or EPS (expanded polystyrene). These coverings offer high R-values and higher densities than other insulation materials. It is an excellent source of restricting air movement.

Benefits

• Weather-resistant
• Versatile
• Fixed installation

Drawbacks

• Moisture-prone

N.B. The cost of rigid insulation boards is Rs. 280 for 24×18 sheet (Expanded Polystyrene)

Can Thin Insulation Coverings Be Used?

The Thin-R technology offers slender insulation materials to restrict thermal and cold bridging. Thin insulation is designed from PIR with thermal conductivity of 0.022 w/mK. It is applied in hard-to-reach locations, especially where critical maneuvering has to be achieved.

It is relatively simple to install. You don’t need an engineer or an insulation expert to fix the additional layering material. It is a lightweight and versatile substance that does not create dusty outcomes. The user will have no issues of respiration or stale air.

Conclusion

Roof insulation is an essential aspect for saving energy costs and enhancing comfort in homes and offices. Select the most convenient type from the above-mentioned insulation materials. Don’t worry, the solution will be budget-friendly and economical in the long run.
