Timber Frame Insulation

Why install a vapour barrier or air infiltration barrier on a timber frame that doesn’t have a thermal value? Low-E Insulation will increase the performance of your timber frame in less space than anything else on the market.

G Taylor, Bolton, UK

“We had a serious problem with damp and mould. Not only did Low-E eliminate the problem but the room is easily to heat too. It was far more noticeable than the cavity wall insulation that caused the problem with the mould”

Wendy R, Stockport, UK

“The Low-E was quick clean and easy to install. It occupied about 1” of space, so the room feels the same size as it was. It used to be too cold to sit in, now it’s easy to heat. I’m over the moon.”

Gerry D, Sunset Building, Luton, UK

“We are managing to meet U-value requirements in smaller studs. Customers love that we can save some floor space and our fitters love that is quick and clean to install.”

G Stone, Stroud, UK

“We use both the vapour and the breathable versions of Low-E Insulation. We’ve tried using other foil insulation products, but they can be time-consuming and difficult to install. Low-E is so easy to work with, we just wouldn’t use anything else.”

Timber Frame Insulation Options

Low-e timber frame insulation is ideal for insulating your home and is the perfect choice for an easy installation. If you are considering insulating your timber framed property please read through the below guides for the type of roof you have in your home. 

Timber Frame - Internal and External (Partial Fill)

With Low-E® PERF installed on the exterior side of the frame as a breather membrane and Low-E® EZY installed internally as a vapour control layer and airtight membrane, the amount of secondary insulation required is greatly reduced. This system creates the most efficient timber frame possible and reduces life-cycle running costs of any building.

Timber Frame – Internal (Partial Fill)

In this example, Low-E® EZY is installed on the face of the timber frame with a partial fill of insulation in the timber frame. This system increases thermal performance, reduces draughting and provides moisture protection, all of which can be problematic in timber frame construction. The counter battening on the face of the frame creates a service void ensuring Low-E® EZY (the vapour barrier) is not perforated.

Timber Frame – Internal (Full Fill)

Low-E® can also be installed on a timber frame with a full fill of insulation. A full fill of insulation is usual if a Blown or Natural Fibre insulation (sheeps wool etc) is used in the timber frame. In this example, Low-E® EZ is used to increase thermal performance, provide air tightness and moisture protection.

Timber Frame – SIPS

SIPS panels are usually installed with airtight membranes internally and breather membranes externally. Installing Low-E® EZY and Low-E® PERF in place of these membranes does not add any labour steps to the build, but will increase the thermal performance of these already highly efficient systems and reduce the building’s lifecycle running costs.

Timber Frame – Passive House

To meet extremely low U-values or ‘Passive House’ standards, specially designed timber frames incorporating Low-E® Insulation can be constructed to reduce thermal bridging and create the most efficient buildings. These can be constructed on or off-site making them extremely versatile.

In this example a rigid foam is installed between the studs with a second layer (unbridged) installed on the exterior side of the timber frame, faced with Low-E® PERF. Low-E® EZ is then installed on the interior face of the frame, before counter battening. Another option is to use an insulated plasterboard. This creates a second unbridged layer of insulation. This will also reduce the amount of insulation required between the studs.
