Applications

Knauf Insulation DriTherm® Cavity Slabs are primarily used for thermal insulation in both residential and commercial external masonry cavity walls. 

These glass mineral wool slabs are installed as the wall is constructed, fitting snugly between the inner and outer leaves and around wall ties. 

DriTherm® Cavity Slabs’ width is optimally designed to match standard vertical wall tie spacings, ensuring tight joints and continuous insulation coverage. The addition of a water-repellent additive further enhances moisture defence, making these. These glass mineral wool cavity wall insulation slabs an excellent choice for any construction in challenging environments.

Frequently Asked Questions (FAQs)

What is the advantage of using Knauf Insulation DriTherm® Cavity Slabs for cavity wall insulation?

Knauf Insulation DriTherm® Cavity Slabs are designed to provide superior thermal performance with a thermal conductivity of 0.037 W/mK. These glass mineral wool slabs are specifically engineered for full-fill masonry cavity wall applications, ensuring a snug fit and maximum energy efficiency.

What is the difference between Knauf Insulation DriTherm® Cavity Slab 32 and Knauf Insulation DriTherm® Cavity Slab 37?

The primary difference between Knauf Insulation DriTherm® Cavity Slab 32 and DriTherm® Cavity Slab 37 lies in their thermal conductivity values, which indicate the material's effectiveness in insulating against heat transfer. The DriTherm® 32 has a thermal conductivity of 0.032 W/mK, making it more effective at insulation compared to the DriTherm® 37, which has a thermal conductivity of 0.037 W/mK.

Both products are designed for full-fill insulation in masonry cavity walls and are manufactured using Knauf's ECOSE® Technology, making them environmentally friendly options. Additionally, both types are non-combustible with a Euroclass A1 fire rating and feature water-repellent properties, though they are not waterproof.

Choosing between these two will depend on the specific insulation requirements and energy efficiency targets of your project, with the DriTherm® 32 offering slightly better insulation performance due to its lower thermal conductivity.

How do Knauf Insulation DriTherm® Cavity Slab 37's handle moisture?

The DriTherm® Cavity Slabs include a water-repellent additive that helps resist moisture ingress, making them an excellent choice for use in all exposure zones, including those deemed 'Very Severe.' This feature ensures long-term durability and consistent thermal performance.

Can Knauf Insulation DriTherm® Cavity Slabs be used in any residential project?

Yes, Knauf Insulation DriTherm® Cavity Slabs are suitable for use in both residential and non-residential external masonry cavity walls. Their design allows for installation during the wall-building process, ensuring seamless integration without the need for additional barriers to meet fire safety requirements.

What makes glass mineral wool slabs like DriTherm® ideal for cavity wall insulation?

Glass mineral wool slabs, such as Knauf Insulation DriTherm® Cavity Slabs, offer excellent thermal and acoustic insulation properties. They are non-combustible, moisture-resistant, and made with sustainable materials, making them an environmentally friendly choice for cavity wall insulation.

Why choose full-fill cavity wall insulation with Knauf Insulation's products?
