The short answer is “yes.” It is usually possible to cement render over timber. To avoid this, you must apply render carrier boards to the plywood, but these can’t be applied directly to the plywood either, since there must be a gap between the two materials to allow for proper ventilation.
Can you render on timber frame?
Knauf Aquapanel Exterior is ideal for use on timber frame, timber battens and metal framed structures. It is mechanically fixed to the timber/steel framework and the system build up is then suitable to receive a render, paint or further exterior cladding finishes, such as slip bricks or tiles.
Can you render a wooden building?
We know that coloured renders are extremely popular these days but breathability is something that cannot be sacrificed when it comes to a timber frame property, so we recommend the use of Silicone render. This is a high tech, thin-coat render with vapour permeability and breathability.
What are the negatives of timber framed buildings?
Disadvantages of Timber frame: They’ll rot – The timber used in modern timber frame home designs are all pressure treated with preservative. Sound transmission – a timber frame won’t resist sound transmission as well as a block built home purely because the block home has more density to it.
Can you render over cement board?

Are timber framed houses a fire risk?
The risk of fire in timber frame buildings is far greater during construction than post construction. The main cause is simply because there are far more sources of ignition and the fire loading is far greater. Sources of ignition will include; Hot works – cutting, grinding, soldering, hot pitching.
What are three disadvantages of timber frame construction?
Disadvantages Wood rot. While huge advances have been made in the treatment of wood to extend its life span, it still remains more subject to rot than concrete. Structural limitations. Fire risks. Building code limitations.
Can you render over Pebble Dash?
Rendering over pebbledash is easy when you use the EWI-065 One Coat Dash Cover (OCDC)! Ensure that the pebbledashed wall is stable and secure by knocking the existing substrate with a shovel or hammer.

Is render board waterproof?

Can you render onto plywood?
The render mix cannot be applied directly to the plywood, as wood is not an ideal substrate for cement render. The best course of action is to prepare the surface, then install a breather membrane onto your plywood, then install timber battens and render carrier boards on top.
Can you cement render onto plasterboard?
Sand & Cement will not stick to plasterboard – however if the plasterboard is properly prepared it will do. Mix some sand in with neat PVA to form a slurry mix and roller this onto the plasterboard. However it should be noted that plasterboard is designed to have the finish coat applied directly to it.
What is the best insulation for timber frame homes?
Using mineral wool insulation, insulated external timber frame walls will typically provide better insulation performance than masonry walls of a similar thickness.
Is timber a good insulator?
Timber is a natural thermal insulator due to having air pockets within its cellular structure. It is 15 times better than masonry, 400 times better than steel, 1770 times better than aluminium.
How do I know if my house is timber framed?
A visual inspection, inside and out, will also pick up on details typical of timber frame construction. In timber frame structures windows are fixed to the frame, not to the brickwork outer leaf. This may result in a deeper external reveal than is common with brick or blockwork construction.
Is it cheaper to render or clad?
