Product Information

Masonry partial-fill cavity walls are a popular type of external wall construction. In fact, they have been used for over a century. So here is what you will need to do when it comes to installing Celotex insulation boards in masonry partial fill cavity walls.

Withstands extreme weather conditions, performing well in temperatures ranging from -30°F to 300°F without losing its adhesive capabilities Note: You will need to install the PIR cavity board between two types of masonry. As a standard measurement, a 50mm residual cavity is a must to maintain between the outer face of cavity insulation and the inner face of the outer leaf. Fitting the Celotex insulationFirst, make sure you have the correct protective gear on hand. Clothing and goggles or safety glasses. As a result of cutting the board, dust and particles can be produced. So it is important protective assets are worn to ensure that you do not inhale the debris. DAFA vapor barrier tape is included in the Nordic Ecolabelling database of construction products that can be used in Swan-labelled buildings. Step one: Apply a continuous band of adhesive to ensure a continuous seal is at the skirting, ceiling level and openings. Thin timber battens can replace adhesive at perimeter edges. High humidity spaces like greenhouses areas with spas or swimming pools, and bathrooms should have vapor barrier protection to protect moisture damage in the rest of the home.

Interstitial condensation can occur in insulated lofts which have non-permeable roofing felt. This results in white fluffy mould on the underside of the roofing felt. Vapor barrier tape is widely agreed upon as necessary in certain conditions, but not as a whole-house solution in every situation. Most experts recommend that vapor barriers are best used in certain conditions and that the vapor barriers used should fit the climate, region, plus the type of wall construction.

Everyone can install a vapour barrier, but attention is required when sealing the overlaps between the strips. If the finish is not carried out well enough, the vapour barrier won’t be effective at all. Step two: Add additional adhesive where necessary, according to manufacturer instructions, then align the insulation against it to secure it into the right position. Step two: Where required, cut the assigned 1200mm x 2400mm board (Celotex PL4000 or Celotex GA4000) to ensure they fit floor-to-ceiling room height.

Materials such as rigid foam insulation, reinforced plastics, aluminium and stainless steel can also be used as they are relatively water resistant but should also be sealed at the joints. Step three: Cut leftover boards for infill panels; use cut-offs where possible and make sure there are no air gaps in the wall abutment.

EMICODE is a trademarked environmental product label focusing on low-emission installation materials and construction products Step seven: Use an angle fillet at the frame and an angle bead or scrim tape at the external corners to finish. If your project warrants vapor barriers, here are some things to keep in mind to get the most of your vapor barrier method and vapor bond tape:

Note: For heavy wall-mounted parts, use independent horizontal battens. You may also need longer fixings to fit heavy items to the masonry, separate from the battens. Split-ability. Likewise, you want tape that’s easy to cut or split for application but that won’t tear by accident and ruin the moisture-resistant capabilities. Requires priming to securely bond with substrate materials, such as concrete and oriented strand board (OSB)For timber structures, initial/temporary fixing of the membrane is normally achieved with stainless steel staples. These may be positioned at the overlap where the vapour control and vapour barrier membrane is to be later sealed with tape. For best practice, fix the membrane using double sided tape, as this will help to minimise penetrations. Where shrinkage or movement within the structure is likely a flexible seal, such as butyl tapewill be of benefit.
