Choosing the Perfect Insulation for Timber Frame Construction

timber frame insulation

An Introduction to Timber Frame Construction 

As timber frame construction becomes increasingly popular, it is important to choose the right kind of insulation for these types of builds to achieve optimum thermal performance and energy efficiency. Choosing the right kind of insulation can be a daunting task, but with our help, it’s never been easier.  

The Importance of Insulating Timber Frame Construction 

Insulation is an essential component of timber frame construction as it helps to regulate the interior environment, reduce energy costs, and protect against moisture damage. Because timber frames are composed of wooden components, they can be more susceptible to thermal transfer than other materials such as metal or concrete.  

Insulation helps to reduce this thermal transfer, allowing for greater control over the internal temperature of a building and reducing the cost of cooling and heating. Additionally, insulation also protects against moisture damage by preventing condensation from forming within the building structure due to temperature differences.  

Insulation Kings’ Top 2 Products For Insulating Timber Frame Construction: 


Consisting of high-quality resin bonded slabs, ROCKWOOL RWA45 is an ideal choice for the quick and easy insulation of walls, roofs, ceilings and floors.  

This material has been specially designed for high acoustic, thermal and fire performance (rated Euroclass A1 non-combustible), meaning it is a highly versatile and safe material for insulating timber frame construction. The material is also water repellent, preventing moisture build-up and damp.  

2. ROCKWOOL Flexi  

Similar to ROCKWOOL RWA45, ROCKWOOL Flexi also offers high acoustic, thermal and fire performance (also rated Euroclass A1 non-combustible), and repels water to ensure the structure of the building stays free from moisture that can cause rot over time.  

The easy to install insulation can be fitted between fresh timber and expands as the timber dries and shrinks, offering a snug fit and optimum insulating effects. This material is ideal for use in framed external walls, internal partitions, pitched roof rafters, intermediate floors and more.
