Building Paper Guide: Choosing and Using Novia A1F Standard for Optimal Construction

Building paper is a term that covers a range of materials that are used to provide a protective layer between the external cladding and the internal structure of a building. Building paper can act as a weather-resistant barrier, a moisture and vapour barrier, a fire retardant, a sound insulator, and a temporary protection for floors and walls. Building paper can also enhance the thermal performance and energy efficiency of a building by reducing air leakage and heat loss.

However, not all building papers are the same. There are different grades, types, and specifications of building paper that are suitable for different applications and environments. Choosing the right building paper for your project can make a big difference in the quality, durability, and comfort of your building.

In this article, we will provide you with everything you need to know about building paper, including:

• What are the benefits of using building paper?
• What are the different grades and types of building paper?
• How to choose the right building paper for your project?
• How to install building paper correctly?
• Where to buy high-quality building paper online?

Benefits of Using Building Paper

Building paper has many advantages over other types of building materials, such as:

• It is easy to handle, cut, and apply, saving time and labour costs.
• It is flexible and adaptable, conforming to various shapes and surfaces.
• It is lightweight and durable, resisting tearing, puncturing, and abrasion.
• It is water-resistant and vapour-permeable, preventing moisture accumulation and mould growth.
• It is fire-resistant and non-combustible, reducing the risk of fire spread and smoke emission.
• It is sound-insulating and noise-reducing, improving the acoustic comfort of the building.
• It is environmentally friendly and recyclable, reducing waste and carbon footprint.

Different Grades and Types of Building Paper

Building paper is classified according to two main standards: BS 1521 and BS 4016. These standards specify the physical properties, performance requirements, and testing methods of building paper.

BS 1521 covers building paper that is made from wood pulp and impregnated or coated with bitumen or asphalt. BS 1521 building paper is graded according to its water resistance, vapour permeability, and weight. The grades are:

• Grade A: High water resistance and low vapour permeability. Suitable for use behind masonry, stone, and brickwork.
• Grade B: Moderate water resistance and moderate vapour permeability. Suitable for use behind timber, metal, and plastic cladding.
• Grade C: Low water resistance and high vapour permeability. Suitable for use as a breather membrane or a vapour control layer.
• Grade D: Very low water resistance and very high vapour permeability. Suitable for use as a temporary protection or a dust barrier.

BS 4016 covers building paper that is made from synthetic fibres and laminated with polyethylene or polypropylene. BS 4016 building paper is graded according to its tensile strength, tear resistance, and water vapour transmission. The grades are:

• Grade 1: High tensile strength and tear resistance. Suitable for use as a reinforced vapour control layer or heavy-duty temporary protection.
• Grade 2: Moderate tensile strength and tear resistance. Suitable for use as a standard vapour control layer or a medium-duty temporary protection.
• Grade 3: Low tensile strength and tear resistance. Suitable for use as a light-duty temporary protection or a dust barrier.

Choosing the Right Building Paper for Your Project

The choice of building paper depends on several factors, such as:

• The type and design of the building
• The type and location of the cladding
• The climatic conditions and exposure to moisture
• The thermal and acoustic requirements of the building
• The fire and safety regulations of the building

To help you choose the right building paper for your project, here are some general guidelines:

• For external walls, use water-resistant and vapour-permeable building paper, such as Grade B or Grade C, to provide a weather-resistant barrier and a drainage plane behind the cladding. This will prevent water ingress and allow moisture to escape from the wall cavity.
• For internal walls, use vapour-resistant and fire-resistant building paper, such as Grade A or Grade 1, to provide a vapour control layer and a fire barrier behind the plasterboard. This will prevent condensation and reduce the risk of fire spread.
• For roofs, use water-resistant and vapour-permeable building paper, such as Grade B or Grade C, to provide a breather membrane and a secondary barrier under the tiles or slates. This will prevent water penetration and allow moisture to evaporate from the roof space.
• For floors, use water-resistant and vapour-resistant building paper, such as Grade A or Grade 1, to provide a damp-proof membrane and a thermal barrier under the screed or the floorboards. This will prevent dampness and heat loss from the floor.

Installing Building Paper Correctly

To ensure the optimal performance and durability of building paper, it is important to install it correctly, following the manufacturer’s instructions and the best practices. Here are some general tips for installing building paper:

• Before installation, check the condition of the building paper and the substrate. Make sure the building paper is intact and free from defects, and the substrate is clean and dry.
• During installation, use the appropriate tools and accessories, such as scissors, knives, staples, nails, tapes, and sealants. Make sure the building paper is securely fixed and sealed to the substrate and the joints.
• After installation, protect the building paper from damage and exposure to sunlight, wind, and rain. Cover the building paper with the cladding or the finish as soon as possible and avoid puncturing or tearing the building paper during the process.
