12.5mm Siniat Moisture Board

Siniat Moisture 12.5mm GTEC Board is a type of gypsum board that is specifically designed to resist moisture and prevent the growth of mould and mildew. It is made with a moisture-resistant gypsum core that is covered with a special moisture-resistant paper liner on both sides, making it an ideal choice for use in high humidity areas such as bathrooms, kitchens, and utility rooms.

In terms of environmental sustainability, Siniat Moisture GTEC Board is made with natural gypsum and does not contain any harmful substances such as asbestos. It is also 100% recyclable, making it an environmentally friendly choice for builders and contractors.

The Benefits Of Using Siniat Moisture GTEC Board – 12.5mm

One of the key benefits of Siniat Moisture 12.5mm GTEC Board is its ability to resist moisture. This is achieved through the use of a moisture-resistant gypsum core, which is specially formulated to withstand exposure to moisture without becoming damaged or degraded. In addition, the paper liner on both sides of the board is also moisture-resistant, helping to further protect the board from the effects of moisture and humidity.

Another benefit of Siniat Moisture GTEC Board is its ability to prevent the growth of mould and mildew. This is important in areas where moisture is present, as mould and mildew can quickly grow and spread, causing damage to the building and potentially leading to health issues for occupants. Siniat Moisture GTEC Board has been tested in accordance with ASTM D3273, and has been found to have no mould growth after 28 days of exposure to high humidity conditions.

Siniat Moisture GTEC Board (12.5mm) is also easy to install, making it a popular choice among builders and contractors. It can be cut to size with a saw or a knife, and can be secured to walls and ceilings using screws or adhesive. The board is lightweight, making it easy to handle and manoeuvre during installation.

Key Considerations

When using Celotex GA4000, you need to satisfy yourself that use of the product meets all relevant national Building Regulations and guidance as well as local, national and other applicable standards relevant for your construction or application, including requirements in relation to fire and applicable height restrictions.
Please refer to the following product documents:

Celotex GA4000 should not be used in the external walls of buildings over 18 metres in height (England and Wales) or 11 metres in height (Scotland). Recent changes to Building Regulations mean that only non-combustible insulation or insulation of limited combustibility can be used in buildings of that height.
