Timber frame construction is an efficient and flexible build method. Compared to traditional masonry, it can accommodate more timber frame insulation in between the wooden studs, as in a cavity.

A continuous layer on the outside provides extra performance, while a layer on the inside gives additional room for electrical wiring. This helps create safe, efficient and positive living and working environments.

Why do we need timber frame insulation?

Timber frames filled with insulation generally offer better thermal performance than masonry walls of the same total thickness.¹ However, their reduced mass and wood properties mean they need the right material to provide strong fire protection and acoustic performance. ROCKWOOL timber frame wall insulation delivers excellent fire resilience and soundproofing capabilities, alongside its thermal resistance qualities.²

Timber frame house insulation is well suited for use in timber frame buildings with its quick and easy fitting and dimensional stability. It will adjust to the small movements of the construction and stay in place for a lifetime.

Benefits of ROCKWOOL products include:

Fire resilience
Sound absorption
Thermal resistance
Flexible application
Water repellent

Calculator and savings

The amount of insulation required will depend on the size and dimensions of the timber frame construction. With thermal requirements mostly determining the insulation thickness required, use a U-value calculator or contact our local technical team about the best product to use.

In most cases, it will be a combination of full fill insulation between the wooden frame with a layer on the in or outside.

Use our ROCKWOOL U-value calculator to determine the thermal performance of the building’s walls/roofs, and possible cost savings. For more details on technical specifications, visit our ROCKSPEC Specification Toolkit.

Why choose ROCKWOOL solutions?

ROCKWOOL timber frame insulation delivers wider value than just thermal performance. The stone wool insulation is highly fire resistant – an ideal property when insulating around flammable wood. It also offers excellent sound absorption, reducing the impact of noise pollution in and outside of a property.³

The range of products include timber frame slabs and rolls to suit different frame dimensions and designs as well as the varying performance requirements. Each product is flexible for varying dimensions and comes with easy friction fitting.

Various features make ROCKWOOL products ideal insulation for timber frame construction. Using the seven strengths of stone they are:

Fire resilient
Water repellent
Sound absorbent
Thermal reductant
Robust
Cost-effective

The low carbon footprint of ROCKWOOL timber frame products is a perfect match with that of the wooden structure. The construction is easily dismantled at the end of its lifecycle, adding to the reduction of our environmental footprint.

Case studies

The problem

F. Socciarelli School in Italy required an efficient, safe and aesthetically pleasing extension. It needed to be sustainable, quick to build and meet the school’s green aims.

The solution

Using a laminated wood and ‘post and beam’ frame system, a façade was constructed with Rockpanel to reduce heat loss, energy consumption and allow breathability. The colours and wood complement the school’s design – and ROCKWOOL solutions are designed to prevent the spread of fire.

The results

F. Socciarelli School benefits from A4 energy performance – making the school nearly zero-energy efficient. Excellent safety and fire resilience add to the building’s success.

We have invested not only for the future but for the present of our children too. To give them a safe place to study, play and live is a matter of pride for us. The school has an excellent level of thermal and acoustic comfort. We also have to recognise that we completed the project in less than 100 days.

Installation

Installing timber frame wall insulation during construction or as prefabricated elements is the common method. It can sometimes also be retrofitted to existing properties.

Key tips:

Choose insulation type – Pick an insulation product suited to the size and dimensions of the frame.
Build airtight – Apply an airtight vapour barrier on the inside of the construction to avoid thermal performance loss.
Weatherproof – Avoid insulation and the timber frame getting wet where possible, as this can lead to leaks before the insulation is installed.

Sustainability and energy efficiency

Timber frames are a more environmentally friendly construction material than others due to their sustainability. ROCKWOOL products are also designed with circularity and a low environmental impact at their heart.

Made from highly sustainable stone wool, ROCKWOOL insulation aims to vastly improve the energy efficiency of every building where it is applied. It can be used to meet the Passive House standards⁴ – creating energy-efficient buildings that promote indoor comfort and acoustic insulation.

Our timber frame wall insulation enhances thermal performance and lowers energy consumption.
