Product Information

In each case, these documents set target insulation (thermal performance) levels that you should look to achieve depending on the work you’re carrying out. The U-value you need to achieve will depend on where your property is located, and whether you are retaining the existing floor slab (and installing the insulation above it) or digging it out entirely. If these are not achievable, the Approved Documents and Technical Handbooks set out some specific scenarios where you can target a worse U-value."

Insulating Suspended Timber A Best Practice Approach To Insulating Suspended Timber

Install tanalised roofing battens to the rafters and joists, this is to ensure a 50mm air gap between your house roof and the insulation, allowing adequate ventilation. 3. Install Insulation Our ‘BB’ range utilises a highly breathable, reflective top membrane which provides you with a secondary rain barrier, whilst allowing moisture to escape safely away. The remaining layers are perforated which keeps the whole product breathable, whilst still providing high thermal performance.

Insulating a roof will greatly reduce the heat loss that occurs through the top of a house, a key element of the thermal envelope. Roof insulation will give you a warm loft, allowing you to convert it or use it for storage. There are several different options for insulation materials within a traditional pitched roof, as well as options for other types of roofs like curved roofs or dormer roofs, allowing you to save energy regardless of the design of a house. Your Options For Roof Insulation Digging out an existing concrete floor to add insulation is an effective yet very disruptive solution. (Image credit: Getty) Are there any tips when installing a concrete floor? Interstitial condensation within a property’s structure can be a serious problem and one that’s expensive to remedy. The correct use of Vapour Control Layers is one way to protect the fabric of a building and reduce the chance of damage to the insulation and timbers. In this guide, we look at how vapour barriers work, why you need them and how to install them. What is a Vapour Control Layer & how do they work? At this stage, depending on the level of insulation you need you can install further insulation boards on top of the joists, attaching them with a nail gun.

When talking about floors, a vapour control layer is positioned at a different level to the damp proof membrane so generally you wouldn’t be able to substitute one for the other. Can you use a DPM as Vapour barrier?The insulation must be thin to avoid affecting door opening height.There are a number of thin insulators, like Sempafloor, warmup boards, or wood fibre boards, that could work in this instance. Rigid foam insulation boards can work as well but are less forgiving of foot traffic.
