Warm Roof Insulation

A warm roof is a roof structure where the insulation is placed over the roof deck, directly under the waterproof membrane. This type of insulation is ideal for flat roofs or low-pitched roofs, where the roof deck serves as the primary weatherproofing layer. Warm roof insulation can be further divided into the following categories:

• PIR (polyisocyanurate) insulation boards: PIR insulation is a high-performance and lightweight material that offers excellent thermal resistance and fire resistance. It is easy to install and can be cut to fit any shape or size of the roof. PIR insulation can also withstand foot traffic and weathering, making it a durable and cost-effective choice for warm roofs.
• Mineral wool insulation: Mineral wool is a naturally fire-resistant material made from volcanic rock or slag. It has good thermal and acoustic insulation properties, and it is also breathable and resistant to mold and pests. Mineral wool insulation comes in different forms, such as batts, rolls, or blown, and it can be fitted around obstacles and irregular shapes.
• Spray foam insulation: Spray foam insulation is a form of insulation that is applied as a liquid and expands to fill cavities and gaps. It provides a seamless and airtight barrier that prevents heat loss and air leakage. Spray foam insulation is also waterproof and durable, and it can adhere to any surface, including metal and concrete. However, it may require professional installation and handling, as it can release harmful chemicals and fumes during application.

Cold Roof Insulation

A cold roof is a roof structure where the insulation is placed below the roof deck, between the ceiling joists or rafters. This type of insulation is suitable for pitched roofs or roofs with an attic or loft space. Cold roof insulation can be further divided into the following categories:

• Fiberglass insulation: Fiberglass insulation is a popular and affordable material that comes in batts, rolls, or blown form. It has good thermal and acoustic insulation properties, and it is also fire-resistant and mold-resistant. Fiberglass insulation is easy to handle and install, and it can fit snugly between joists or rafters. However, it may not be suitable for areas with high humidity or moisture.
• Cellulose insulation: Cellulose insulation is an eco-friendly and sustainable material made from recycled paper and treated with borate. It has good thermal and acoustic insulation properties, as well as fire resistance and insect resistance. Cellulose insulation is easy to install and can be blown into place, filling all voids and gaps. It can also absorb moisture and reduce noise levels, making it a comfortable and efficient choice for cold roofs. However, it may require proper ventilation and conditioning to prevent mold growth.

Benefits of Roof Insulation

Roof insulation can bring many benefits to your property, both in the short and long term. Here are some of the key advantages of investing in roof insulation:

Reduced energy bills

By improving your building's energy efficiency with roof insulation, you can save up to 50% or more on your heating and cooling costs. Insulation helps to trap the heat inside your building in the winter and prevent it from entering in the summer, thus reducing your reliance on HVAC systems. This can lead to significant cost savings over time, especially for larger or commercial properties.
