The Isoboard and Summit XPS Ceilings are the latest fashion in homes in South Africa. Isoboard Ceilings are available in thicknesses from 25- 80mm thick, ideal for all families and households with limited ceiling volume space to achieve the correct R-value. The thickness of the ceiling boards governs the cost of Isoboard. We offer the best Isoboard price in SA.

Having Summit XPS installed is a neat and clean operation. The application is almost dust-free as there is no skimming and dust in these applications. For an average house, most homes can have ceilings installed in two to three days.

Benefits of Summit XPS and Isoboard Ceilings

  • We will comfortably complete an average bedroom of 30m2 in one day. By far the fastest Ceiling to install.
  • One can’t compare Isoboard Thermal Ceilings to traditional Rhinoboard types.   
  • No painting is needed for these ceilings as they are fresh, clean white and do not fade.
  • The only Ceiling that is also insulation. Thermal Insulation properties are excellent.
  • Isoboard will outlast the lifespan of many homes.
  • It has a Modern, clean ceiling.
  • Isoboard XPS does not absorb water. So, there is no stress as with traditional ceilings that absorb moisture.
  • Fitting these ceilings is a clean, dust-free application, with no skimming, sanding or painting.
  • Importantly, installing Isoboard is quicker than traditional ceiling board applications.
  • These Thermal ceilings will improve the indoor temperature in summer and winter.

Isoboard Isopine Ceiling Option

Isopine is the name given to ceiling boards with the typical tongue-and-groove finish. We all remember the old, knotty pine ceilings produced with this finish.

An Isopine Ceiling is made of Isoboard or XPS, with a tongue-and-groove finish similar to old knotty pine ceilings. The main difference is that it is made of smooth, clean XPS  rather than wood.

Isoboard Thermal Ceilings The Smart Choice

Everything You Need Too Know About Isoboard

What Are The Isoboard Applications?

  • Isoboard Ceilings: Standard Ceilings as well as Exposed beams. In all new homes, as well as retrofitting existing homes.
  • Factory installation application. We have a few options for XPS Ceilings in the factory environment.
  • Wall Cavity Insulation Isoboard: Ideal for all new builds to reduce Thermal Heat transfer through the brick walls.
  • Floor Insulation: This reduces the cold air below, especially in homes built near rivers or dams.
  • Between Walls: Ideal option for reducing heat flow into the home in summer.

Isoboard Thermal Ceiling insulation is undoubtedly one of the best ceiling options today. Its excellent thermal insulation properties and aesthetically pleasing appearance make it a good choice. Unfortunately, the only downside is that these ceilings do not reduce noise from the roof into the home.

For this reason, it is essential to fit roof insulation with a high NRC (Noise Reduction Coefficient). For example, the New Think Pink Aerolite with TEL Fiberizing technology or the Knauf Ecose Insulation will stop noise from metal roofs. Unfortunately, the Isotherm Insulation has a very low NRC. We install the new Pink Aerolite in nightclubs and pubs as insulation and soundproofing. These thermal insulation ceilings reduce the amount of roof insulation required.

Isoboard XPS Applications

How To Install Isoboard Ceilings?

Installing either Isoboard or Summit XPS is relatively simple. 

  • We generally fit the wooden brandering at 500mm centres. However, some installers use up to 700mm. Over several years, our experience has taught us that a smaller gap of 500mm is the best option.
  • Measure between walls and cut all XPS Ceiling boards to size.
  • When cutting the boards to size, remove 40mm from the length for an easy fit.
  • Then, place the Ceiling board between the walls, ensuring an equal gap.
  • The next step is essential! We must apply XPS glue to all the purlins before we install the ceiling board.
  • Once completed, wash the ceiling boards with a damp cloth to remove the static and fit the cornices.

How To Install Isoboard Between Beams?

In many new homes, we fit the Isoboard Ceilings above the beams at the building time. However, as a retrofit, we install the boards between the beams.

Importantly, before fitting the XPS ceiling boards, we must ensure we have the correct space to secure them. When installing Isoboard or Summit XPS ceilings, the fastening points are no more than 400 mm apart. We will fit the boards between the beams from inside the home. The gap between the beams is inconsistent in almost every roof. For this reason, we must measure accurately between the roof trusses for every Summit XPS Ceiling board.

Once we have installed all the ceiling boards and are happy with the gaps on the sides, we can fit the quarter-round cornices. These cornices take up very little space, allowing more of the wooden beam to be the feature.

In most cases, the wooden beams are painted white in advance.

Isoboard Ceilings For Factories

As we know, factory spaces can be extremely hot in summer and cold in winter. Sadly, there are few options to reduce indoor temperature in industrial premises. 

We have found a few options that work exceptionally well in reducing the industrial area’s summer heat and winter chill through demand.

Our first option was to fit the Summit XPS Ceilings similarly to traditional applications. Some of our recent applications include the Suspended ceiling grid, in which we install the ceiling boards between the main tees. 

We supply 50mm Isoboard Ceiling boards to be fitted in Industrial premises to block the inside of the roof space. In particular, this application is to encapsulate or block asbestos fibres from entering the premises. 

On factory premises, we prefer the Sisalation foil over the isolation foil. This combination gives the building a stunning look and provides excellent thermal benefits with all year round.

Isoboard Between Walls

To some, this may seem like madness. However, insulated walls improve the indoor temperature in summer and winter.

When the home is built, we will fit the XPS boards between the walls in the cavity space. All buildings have a cavity space between the bricks to allow hot air to escape.

However, when we install high-density XPS, we create a thermal barrier. The thermal insulation barrier stops the heat build-up on the walls from entering the home.

The thickness of the Isoboard or XPS varies depending on the specifications. The most common thickness is 50 mm. However, in the last year, we have had several applications where the specification is 100mm. 

The simple application requires a clip fitted to the XPS for ultimate strength.

Fortunately, the outcome is a very energy-efficient home.

XPS Under Floor Application

For many, the question of underfloor insulation seems like madness. However, in some cases, it can be one of the most important. 

As we know, homes near rivers or above underground water will be colder in winter. Before we lay the concrete slab, we fit either Summit XPS or Isoboard ceiling panels to reduce the flow of cold air from below.

In homes with underfloor heating, there is a substantial benefit.

Adding XPS under the foundation of the build or home or below the floor of the home when using heating ensures perfect heat gain with almost no heat loss down. 

As a result the heat generated by the under floor heating is all focused upwards. 

This results in very little heart loss n the home. At the same time we are saving energy on heat loss undergound.

6 rEASONS YOUR hOME nEEDS iSOBOARD cEILINGS

  • Your home needs an Isoboard Thermal Ceiling to improve the indoor temperature in summer and winter.
  • Also, XPS Thermal ceilings will outlast the lifespan of most modern homes.
  • The extruded Isoboard ceilings offer a high-quality, smooth sheen finish. The advantage of the smooth finish is that no painting is required.

As we know, Isoboard Ceilings have many benefits. However, the three most important reasons are as follows.

  • Isoboard Thermal Ceilings are the most advanced ceiling boards, and their thermal insulation properties are excellent. By installing them, you can give your home a lifetime of comfort and energy savings.
  • Secondly, Isoboard Ceilings absorb less than 0.5% water by volume. The XPS ceilings are a bargain, considering how many homes have ceiling damage related to roofing leaks or leaking water pipes.
  • Thirdly, XPS Thermal Ceilings’ long lifespan will outlast the life of most homes. Their modern, clean-cut look will remain fresh for many years.

We love fitting Isoboard Ceilings as they are a clean, simple ceiling option for any home or factory.
