Celotex is the market leader in rigid PIR insulation materials. From its headquarters in Suffolk, Celotex is at the heart of energy efficiency measures aimed at achieving the UK's carbon reduction targets. This video outlines practical installation advice on Celotex PL4000. Our high performance thermal insulation board where PIR insulation is bonded to 12.5 mm taped edge plasterboard. PL4000 is available in a range of thicknesses, and possess an in built vapor control layer.

It can be used in new build up application as well as providing the perfect solution for refurbishment projects. Prior to installation it's important to ensure the wall is sound, secure, free from contaminants and dry.

The benefit of using a direct bonding method is not only speed but it also allows for variable flatness of the wall. Concrete should be dampened prior to application and occasions a primer may be necessary. The drywall adhesive should be prepared, mixed and applied in line with manufacturer's instructions. In all instances the background should be plumb for alignment making allowances for high spots on the masonry.

Mark chalk lines on the floor and ceiling to establish the new wall plain. Vertical guidelines on the wall should be marked at 1200mm centers to indicate the positioning of the boards. The installation should start from an internal corner, or a window, or door reveal. A continuous bed of adhesive should be applied around the perimeter of the wall as well as around any services or other openings.

This is especially important when considering the air tightness of the building. All conduits and piping should be installed prior to commencement of all works. The insulating backing of the laminates should not be remove to accommodate services, with each dab approximately 75mm by 250mm in dimension. Individuals debs should not bridge bonds. Typically the adhesive dabs should cover at least 20% of the board area. The board should be cut approximately 15 mm short Floor to ceiling height and positioned with the bottom edge resting on packing strips. Tap the board into position with a straight edge, checking alignment with the chalk lines. Once positioned, the board should be lifted to the ceiling edge using a floor lifter and supported until the adhesive is set. Once set, nailable fixings should be applied at midpoint of the board and approximately 25mm from the board edge. Other boards should be installed closely butted together using the same technique. Metal framing systems can also be direct bonded to the wall. The same preparation and setting up procedure should be used. Additional vertical and vertical and horizontal lengths should be applied around services, doors and windows. Regardless of the method used, additional consideration should also be given for the fixings of cupboards, radiators, etc.

Commonly Timber Frame battens & metal frame systems can be used to support the boards. As for a direct bond method, correct preparation of the wall is essential. The installation should start from an internal corner or a window or door reveal. The board should be cut approximately 15 millimeters short of the floor to ceiling height and positioned with the bottom edge resting on packing strips. Place the boards into position on the frame checking alignment with the chalk lines on the floor and ceiling. Once positioned, the board should be lifted to the ceiling edge using the floor lifter and supported with additional packing at the base of the board. The board should be fixed using appropriate drywall screws at 300mm centers, along the vertical and horizontal elements of the frame. Other boards should be installed closely butted together, ensuring three screws are fixed along each tapered edge and positioned equally along the height of the board.

For windows, reveals and external angles. It's important to consider the junction of the installation to avoid thermal bridges. The board should be extended beyond the corner. Cut back the insulation to form a neat junction with the reveal board or wall lining. Apply a bed of adhesive and place the cut board into it. Once the adhesive is has dried, two nail-able fixing should be installed halfway up the board and 25 millimeters from each edge.

When using Celotex PL4000, there are a variety of thicknesses available.Thin solutions are available for specific use and reveals. For board joints, an appropriate joint filler should Should be firmly placed into the tapered edge with tape then set into the filler. Traul apply two or three applications of jointing compound, allowing each to set before the next application. Each applications should be feathered out beyond the previous application. Screws and nails should receive the same number of applications. In circumstances where square edges meet, it will result in a raised profile. In these situations, the secondary application of joint filler should be emitted. The feathering should be extended to conceal the joint. For internal angles, simply crease the jointing tape and follow the same procedure for board edges.

At external angles, an appropriate Tape can be used or alternatively an angle beep can be used when extra protection is required. A finishing scheme coat of two millimeters of plaster should be applied to complete the installation. Apply plaster to the boards and joints with firm pressure. The joint adhesive should be firm but not quite set. Two applications should be used Two applications should be used to achieve the final fitness of two millimeters. Apply the second coat onto a wet primary coat and trial to a smooth, flat finish. Once dry, the final surface is ready to be decorated. Consideration should be given to the need to prime the surface prior to painting or papering. Celotex PL 4000 is fast and efficient solution for new build applications, or to provide thermal upgrades in any refurbishment project. The premium performance of Celotex solution will help to optimize your space.

Video Transcript

Rockwool is a natural insulation product made from basalt rock which is produced by the power of volcanoes. It's melted in our furnace and mixed with a by-product of other processes. It's then spun and cooled to create a wool effect. Roockwool, this forms the basis of many insulation products used in all areas of construction. Rockwool's team of demonstrators are out to spread the word across the UK showing the unique benefits of our products.

As it's stone-based, Rockwool insulation is non-combustible and can withstand temperatures of more than 1000 degrees Celsius. Put a blow torch next to a piece of Rockwool insulation and it will begin to glow. But doesn't catch fire or melt. That means Rockwool insulation acts as a barrier to fire slowing the spread of flames. Rockwool insulation is also water repellent. It actually resists water and drains it away. Even when we submerge Rockwell, it simply comes back to the surface and water runs off it, and the interior of the wall remains dry and unaffected. As Rockwoll is comprised of inorganic materials, it prevents the growth of mold and mild dew. Another characteristic of Rockwoll insulation is it's ability to absorb sound to keep your home quiet and comfortable. This box is lined with Rockwoll sound installation.

A loud alarm is activated and placed inside the box, the lid put back on and the sound is virtually eliminated. Remove the lid and the alarm is still going back on, and the sound is almost gone. Rockwoll sound insulation is highly effective as to preventing noise transmission from room to room. Thanks to it's higher density and non directional fiber orientation which traps sound waves and dead in vibration. Fit is critical in achieving performance of any insulation.
