The Benefits of using Knauf 125mm Dritherm 32

One of the key benefits of this product is its excellent thermal performance. It has a thermal conductivity of 0.032 W/mK, which means it can provide high levels of insulation and help reduce energy consumption. This makes it ideal for use in both new and existing buildings that require insulation upgrades.

Another benefit of Knauf Dritherm 125mm Cavity Slab 32 is its acoustic performance. It has a high-density structure that can effectively absorb sound waves and reduce noise transmission. This makes it an excellent choice for buildings located in noisy areas or those that require a quiet environment, such as hospitals or schools.

This product is also easy to install. It comes in pre-cut sizes that fit perfectly into standard cavity walls. The slabs are designed to be friction-fitted, which means they can be easily pushed into place without the need for any adhesive or mechanical fasteners. This makes installation quick and hassle-free, saving time and reducing labour costs.

Knauf Dritherm 32 125mm is a safe and durable insulation solution. It is non-combustible, which means it does not contribute to the spread of fire. It is also resistant to moisture, which means it will not sag or slump over time. This ensures that it maintains its thermal and acoustic performance for the lifetime of the building.

In addition, Knauf 125mm Dritherm 32 is environmentally friendly. The product is manufactured using sustainable materials and has a low environmental impact. It is also recyclable, which means it can be reused at the end of its life cycle.

Installing 125mm Knauf Dritherm Cavity Slab 32

Installing 125mm Knauf Dritherm Ultimate Cavity Slab 32 is a straightforward process that can be carried out by a competent DIY enthusiast or a professional contractor. Here are the general steps involved:

  • Preparation:
  • Before installing the insulation, it’s essential to ensure that the cavity wall is clean and free from any debris or protrusions that could affect the insulation’s performance. Any existing insulation should be removed to make way for the new installation.

  • Cutting the insulation:
  • Knauf Dritherm Ultimate Cavity Slab 32 – 125mm comes in pre-cut sizes that fit standard cavity walls. However, if necessary, the insulation can be cut using a sharp knife or saw to fit any irregular spaces.

  • Installing the insulation:
  • The insulation is designed to be friction-fitted into the cavity wall. Start by placing the insulation at the bottom of the cavity, ensuring that it fits snugly. Then work your way up, filling the cavity with insulation until it is completely filled. Ensure that the insulation is flush with the surface of the inner leaf.

  • Finishing:
  • Once the insulation is installed, it’s important to ensure that the cavity is sealed to prevent any air leakage. Seal any gaps or holes with a suitable sealant or tape. Finally, replace any removed skirting boards or architraves.

It’s worth noting that proper safety precautions should be taken when handling insulation, including wearing protective clothing, gloves, and goggles. If you’re not confident in carrying out the installation yourself, it’s best to hire a professional contractor to ensure that the insulation is installed correctly and safely.

Correctly storing 125mm Dritherm 32

Proper storage of Knauf Dritherm Ultimate Cavity Slab 32 (125mm) is essential to maintain its quality and performance. Here are some tips on how to store the insulation correctly:

Store the insulation in a dry and secure location: Moisture can affect the insulation’s performance and cause it to sag or slump over time. Therefore, it’s important to store the insulation in a dry location away from any potential sources of moisture. The storage area should also be secure to prevent any damage or theft.

Keep the insulation off the ground: To avoid any potential moisture damage, store the insulation off the ground on pallets or racks. This will also make it easier to access and transport the insulation when needed.

Protect the insulation from sunlight and weather: Exposure to sunlight and weather can also affect the insulation’s performance. Therefore, it’s important to cover the insulation with a tarpaulin or plastic sheeting to protect it from the elements.

Avoid stacking heavy objects on top of the insulation: 125mm Knauf Dritherm Ultimate Cavity Slab 32 is designed to be resilient and durable. However, stacking heavy objects on top of the insulation can cause it to compress, affecting its performance.

Store the insulation in its original packaging: Knauf Dritherm Cavity Slab 32 (125mm) is typically supplied in polythene packaging that protects it during transit and storage. It’s important to keep the insulation in its original packaging until it’s ready to be installed to ensure that it stays clean and protected.
